What video settings work (all rants off please :) )

I think most of the active members are aware of the video difficulties SO please (please, please) turn your rants off for this thread. What I am trying to find is a combination of settings that DO work.
My preferred codec is MP4.
From some suggestions in other threads, I have tried these encoding settings.
Screen resolution: 320x240
Frames Per Second: 30
Kbps: 300
Audio codec: [email protected]
...and I am playing back on TCPMP 0.72RC1 using these settings
Options/Video: Raw FrameBuffer
Options/Video/Dither: Off
Options/Video/Pixel Aspect Ratio: Auto
Options/Settings/Advanced/Slow Video Memory: On
Options/Settings/Buffering/Preload at Underrun: 85%
Using this, all I get for video is about 1 frame every 3 seconds. Audio is fine.
So can anyone add this this for getting MP4 to work?
Do I need to use a different codec? If so, I would prefer something other then AVI, since I have a mixed environment. Does anyone have suggestions on the best cross platform Codec, that has work well on the Kaiser?

I'd be interested in this too. I can play back videos taken from the video camera flawlessly but when trying to encode them to the same MP4 codec they can get choppy. Not sure what gives :0

Using WMV here
I couldn't get the mp4 output from my ATI Multimedia Centre software to work at all on my TyTN II so I've settled on WMV 9 at 352 x 288 resolution and 372 kbps (thats at 15 fps). Anything with higher bit rate than that seems to cause problems with to much screen tearing during fast movement scenes.

You might want to follow this thread... seams that the Core Player is attacking this known problem for the Tilt. I'm by no means an expert on this, but seems like the Qualcomm QTV technology for the video has some issues:
http://www.corecodec.com/forums/index.php?topic=596.0

I use PDXE, Lathe, and a few others to encode Divx videos at 320x240 video quality at "28" audio in stereo at 96 or 128k MP3 with a total bitrate under 500k (usually shoot for 475kbps). If the encoder allows it, for portable video I bump the audio volume by 15% and I increase brightness as well. To me most movies look darker on the small screen. If cropping is allowed I crop widescreen content, cutting off some of the sides of the picture to get closer to the 3:4 ratio of PDA screen. I also like to turn the brightness down as much as possible to increase battery life so the bump in brightness helps there as well. An average movie 1:50 length is about 480MB
I've used Core and TCPMP (currently using TCPMP for the youtube capability) and use Rawframe buffer as well. I'm sure that Core 1.2 will make things even better.
I get 30FPS and normal fluid video, looks like my other 8525, hx4700, and Archos 320 and 400 units with crisp clear video, no complaints.

This MP4 doesnt play on my pc only the phone???

I have an TiLt and when i try to record videos on my phone in MP4, it appears to work fine and i can play it back on my phone using TCPMP. but when i try to run this on my computer rnning vista it only shows video with no sound.
What can be causing this, is there a way to fix this and has anyone else noticed this..
ps. i hope ths has not been spoken about b4, i hate sounding like a nubie

There's lots avout video formats in the wiki here:
http://wiki.xda-developers.com/index.php?pagename=The H.264 (a.k.a. MPEG-4 Part 10 and AVC) Bible
FWIW my mp4s recorded on my TyTN II wont playback on my PC either, it's simply a case of finding a suitable codec.

recorded videos on Tilt not playing on vista with sound!! I GOT IT FIXXX

Hey thanx for the reply but VLC is what i got installed and doesnt work, thought someone else had the same issue like mine. The .MP4 files that the TiLT records doesnt playback properly. PROBLEM is : I get the video portion just fine, but no sound. I have the. I tried in Media Player, VLC, QuickTime, RealPlayer, etc.... All the same... video plays but no sound.
I googled the issue and found out some other HTC phone users got it too and a couple solutions i found are.
1. In QuickTime it says: "Error 2041 - Invalid sample description in movie"
Solution: Checked the Apple.com or quicktime forums, if you use quicktime, change the file name from .MP4 to .3GP and it will work, it will not work otherwise. (if you dont know how to rename the files or dont see extension, Windows vista or XP go to tools>folder options>view>uncheck hide file extensions for known file types and voila)
2. Since I did so much reading on this, I got a new player (KMPlayer) that beats vlc in my books it plays the files recorded from the tilt just fine unlike VLC latest build, its fast and does all vlc does but it has a better GUI and plays anything you throw at it. you can get kmplayer here
Conclusion: The TiLt is fine, just that I couldnt get the right player to run the video files it records. apparently there is some issue with the qualcomm processor and the video output files of .MP4, some others have reported issues with any .MP4 files and had to do the same listed above.
Hope this helps someone here...

if you want an mp4 player on your pc for free, go to nokia.com

MANY THANKS! zulualpha7,
I have had the error 2041 problem for a long time and have never been able to play vids recorded on my TyTn II on my PC.
I almost installed various codec packs as other forum members have done but after reading about potential problems of having multiple codecs for same file type and upsetting the system I decided not to do this.
I have some really important 'once in a lifetime' family moments like my friend's son catching his first fish etc... I though they were all lost for ever.
I just downloaded latest Quicktime and renamed file extensions to ".3gp" like you said and now I can watch everything!!!!
Thank you so much this really has been a big improvement for me.
ONCE AGAIN THIS FORUM ROCKS! Thanks to everyone for so much fantastic helpful info.

HTC S730 Video playback

Hi everyone.
I know, bad video performance is a known issue (see http://www.htcclassaction.org/).
But on my device I'm not able to play any video file without bucking image. About every second, the image stops for a short instance (I get sick watching this for more than a minute )
I tried different video files with different formats:
- wmv8 with 300 kbp/s, 25 images/s, 320 x 240 with wma8 128 kbit/s stereo (converted using All-in-1 mobile video convert)
- mpeg-4 (H.264)/AVC, between 128 and 1248 kbp/s 25 images/s, 320 x 240 and 64 to 128 kbp/s for stereo audio (converted with SUPER)
- a couple other files found on the web
I tried to play them with the installed Microsoft Media Player. Normally sound is ok, video never is. For the video it seems to make almost no difference what settings I use. mpeg-4 is a bit better than wma8. But between the 1248 kbp/s and the 128 kbp/s video there is no difference (besides th artifacts), It's bucking the same.
Can anyone please tell me, what codec / settings are playable on the HTC S730? Or can someone post an example video file that plays well on his device?
Any help is appreciated!

Window's media player is your problem in this case.
I have Core player and that TCPMP one posted above. If I drop resolution on some of my files I can play them perfectly in core player, and with TCPMP set to low (medium) all videos play fine. High action scenes sometimes cause a little studder so I am going to lower the origional res down a little bit.
The only problem I have run into is on some higher quality ones the phone runs out of page file memory which I currently have set to 1024 within TCPMP. Make sure your phone's memory is clear when trying to watch stuff and you should be just fine. Especially if you are dropping the resolution down that low.
I will try to take a short video of a video playing

Works!
It works! The problem really was windows media player!
Thanks a lot for the hint - I think I'd never try to change the player...
Frame rate is not perfect yet. I still have to figure out what the best settings are, but it is already ways better than before.

Hehe, no problem. WMP is not a well optimized player. For my computer and HTPC I use zoom player, it can handle 720p on a processor that really shouldnt be able to.

Video settings
Hi all.
After spending a lot of my spare time I finally found the right settings for converting videos for the HTC S730.
First I tried to convert videos to H.264/AVC and WM8. This does not produce anything you'd like to look at. Even with very low video bandwidth (200 kbit/s for video) the best I got was below 10 frames/s. With TCPMP it's a bit better than with Windows Media Player but there is no big difference.
But if works fine with the following settings:
Container : AVI
Video Codec: MPEG-4 480 kbit/s
Audio Codec: mp3 44.1 kHz stereo 128 kbit/s
For converting I use the free SUPER (http://www.erightsoft.com/SUPER.html).
This way I get close to 25 frames/s (maybe 10% are dropped).
Please note that such a video cannot be played with the Windows Media Player. (AVI is a Microsoft format, but it looks as the player doesn't like the codec.) However it plays fine on TCPMP 0.71 (from here: http://picard.exceed.hu/tcpmp/)
My daily train rides are much more pleasant now

With my S710 (has a 200MHz TI OMAP850) I'm streaming 25fps/200kbs of my VLC server (which transcodes digital sat streams in real time). I'm using .ts container, mpeg1 vid, mp2 audio and Coreplayer as client.

I have an episode of Top Gear that I can play in TCMP at mediuam quality, its video rate is 199 / 25 fps.
WMP will only play the non tweeked files, in other words if it was compressed into any codec (xvid, divx, ogg, mkv) and other of the others WMP will not play it unless it has the codec installed. The other players (core player / TCMP) come able to read these files upon install so they work better.
With TCMP most of my files do not even have to be changed, just dump them on the sd card and with the player set to medium quality it goes right through them. Now some high action / motion scenes will cause a little lag or slow down but not much and not for long.

This is soooo ridiculous! WMP worked just fine in the older 200mhz devices! Now we have to switch to TCMP and make sure that no programs reside in memory before playing ANY videos? Ridiculous! HTC is losing a lot of faithful customers with this.

It depends on the type of file's your trying to play.
Just like WMP on the PC, it wont play anything without the codecs for them.

[Encoding Movies] best program, settings?

Hiya,
Since all my old music video's are in 320x240 format I'd like to re-encode my ORIGINAL music video files into 640x480 format.
Until now I've been using Nero Recode which gave me ease of use and a pretty nice result.
What program(s) are you using to encode your material and what settings?
I know the Diamond can pretty much play a divx/xvid without re-encoding, but I'd like a smaller filesize so I can place more files on it.

pocketdivx encoder is free, simple to use and produces good results

I use SPB Mobile

Thx for the suggestions.
I've been searching/reading a bit and I'm not an encoding expert, but from what I've read the best possible format would be H.264/AVC?
It would be awesome to get such an awesome movie quality that 'certain other brand phone users' would turn green in envy
My search continues!
Check THIS out for alot of info on the H264 format

I've tested a bit around with encoding Movie files.
Under Windows i become good results with Super from eRightSoft
But i use the most time Linux Debian. There is "AviDemux" you're friend
I'd converted some of my Musicclips in MP4 with AviDemux. In advance:
"MPEG-4 ASP Xvid" at "800KBit VBR"
"AAC (FAAC)" Audio at "128KBit"
Super from eRightSoft in advance:
"H.264 AVC" at "1000KBit CBR"
"AAC (LC)" at "128KBit" Audio
The results seems very pretty so far. But the video seems to stuck if the Bitrate is more than 1100KBit. All tested with Mobile Windows Media Player, because i dont have Coreplayer at the moment.
The old TCMP 0.xx gives an horrorble output. Too many framedrops etc.
Which formats are natively supported from the Qualcomm Chipset, knows that anyone ?

Slow video playback

Is anyone having problems with video playback?
WMV files they are played very slow (loosing a lot of frames). With MP4 I got best results but not the best. Any suggestions??
Thanks

WMV
I can't even get the above files to play

are you using Media Player? as video playback has always been awful on Medial Player on every pocket pc or smartphone ive everhad.
install TCPMP and video playback will be perfect, and will play any file you throw at it

Thanks for the tip keyz86. I'll try it.

no problem, glad to help a fellow Dimondarian

Dimondarian Cool hehehe

Has anyone been able to play a full resolution file without skipping?
I am using CorePlayer now but if another player works better, please say so.
With Coreplayer I benchmark about 85%, which is not good enough.
I believe the Diamond should be able to get 100%.
I found that an encoded mp4 file would play about the same as the original avi xvid file...
What do you use to encode videos specifically for the Diamond?
Come on!! Post your results!

What video settings do you use with coreplayer ?
DirectDraw, GDI or what ?
This is what i get:
With these configs.:
But with some other videos i have i get only 88% speed and some frame drops and tearing.
Doesnt the Diamond has a good video hardware.
Imo, it shouldnt lag at all.
Ive read somewhere that it doesnt use the hardware correctly since the drivers were not fully implemented. Not sure if its true.

Still looking for a good solution... any more help?
Coreplayer is still choppy ...

Yeah, I wasn't able to get WMVs to play using this, either.

I think what we need to have a look at is which encoding, resolution, bitrate, fps, etc are optimal for the diamond using core player.
I'm experimenting a bit. Will report back in a bit...

I've just got my Ignito (diamond) a couple of days ago, but I've got a long history of video playback on hand helds. Since this is my first time post, and I happen to have a bit of time on my hands.... I'm going to convert a file into a series of different resolutions and settings to see which one will perform the best. I know the objective is to get a full res one to play, but I'll see what I can come up with.
Also, I'm using the default ROM at this time.

With Coreplayer you should use the 'QTv' display option - this is hardware accelerated and beats 100% benchmark on every AVI I have tried. If you get a blank display using this mode, you are using an old version and need to update.

Alright. After trying a bunch of different codecs, encoders, video and audio formats at various resolutions I came the conclusion that for now, full resolution video is just not possible without jerky movements during continuous motion or fast action scenes.
My eyes are very sensitive and I get really irritated if playback is not perfectly smooth.
So far what works the best in achieving this kind of natural playback is AVI as the output container with XviD video codec at 480 x 360 resolution, and mp3 audio. I set the video and audio bitrates to match whatever the source video was (min 864 kbps and max 1008 kbps for video and 192 kbps for audio).
Even then, CorePlayer is a must with the following settigns: QTv On, TytnII driver mode On and Smooth Zoom On.
Every now and again CorePlayer will show only a purple screen during playback when QTv mode on. At that point I usually do a soft reset and it starts working again.
This issue may be resolved with an upcoming release of CorePlayer (1.3) but until then, the solution above works exceptionally well.
I'd be very interested in anyone else is having success in other ways...

320 by 240 versus 640 by 480
I have done some playing with conversion and have found that the Diamond (currently) does not support the 640 by 480 settings with a good bitrate. The BEST conversion I have found (using Coreplayer to play back the files) is using the BETA Version of the Pocket Divx Encoder (http://www.pocketdivxencoder.net/EN_index.htm) and using the HTC Diamond Template (NON VGA!!!!, there is a VGA and non VGA) that team has developed. They have done an excellent job!
The output settings -
Dimensions 320 by 240
Video Quaility - "36" ... 584 kb bitrate
Hopefully an update by HTC or coreplayer will be released to fully utilize the resolution that the Diamond SHOULD be able to support, but for a clear, non jerky playback, this is my 2 cents

im able to play those axxo dvdripson using coreplayer without any sort of convertion....

I want to share my experience. I am using core player and trying to recode unprotected high-definition TV shows (original resolution of 1920x1080) that I've recorded on Windows Media Center (.dvr-ms files) to watch on my Sprint Diamond. Unfortunately .dvr-ms are poorly supported, and the only program I've found to recode is TMPGEnc 4.0 Xpress.
I am using Core Player version 1.2.5 build 4506, and my video output is QTv Display with the Tytn II driver mode enabled.
Like everyone else here, I have had horrible results when converting the shows to DivX at 640x360 at any usuable bitrate (above 500 kbps). Benchmarking in Core Player yielded a playback speed of 66% or so (completely unacceptable, obviously). So I played around with the resolution and bitrate, and finally settled on the following:
Format: DivX
resolution: 512x288 (maintains the 16:9 aspect ratio of the original)
Video bitrate: 850 kbps
Frame rate: 29.97 fps (progressive)
Audio: MP3
Audio bitrate: 80 kbps, 48kHz sample rate
With those settings, I have a 104% playback benchmark with around 25 dropped frames compared to several thousand played, and about 29.5 fps. Basically, it is completely smooth audio and video.
I was still PO'd that I had to sacrifice so much resolution and bitrate on a supposed media device, so I played around with other formats. WMV was awful. MPEG-2 was awful, and avi was passable, but no better than DivX. I also decided to try h.264 (MPEG-4 AVC). Here are the settings I used:
Video Format: MPEG-4 AVC (saves as .mp4)
Resolution: 640x360 (still maintaining the original 16:9 AR)
Video bitrate: 1000 kbps
frame rate: 29.97 fps (progressive)
Audio format: AAC
Audio bitrate: 96 kbps, 48kHz sample rate
Core Player absolutely choked on this. It was unwatchable, and the benchmark revealed a playback speed of 50%. Dropped frames were higher than played frames (!) and framerate was 13 fps. Obviously not successful.
But, before I deleted the file, on a whim I decided to try Windows Media Player and...it was completely FLAWLESS playback. Absolutely beautiful, smooth motion, no audio stuttering, slow and fast pans were the best I've ever seen on a WM device.
Why??? Is there something I'm missing about this that someone can elaborate on? Is this the fabled "hardware acceleration" that I've read so much about? I should note that WMP had a hard time on a 320x240 .wmv file, so I can't really understand how it is able to play a 640x360 .mp4 file so smoothly. In any event, I have found my perfect file format, and, surprisingly, it doesn't involve Core Player in any way.
-R

The thing is that HTC didn't release any kind of SDK for Diamond or Touch Pro and companies like CoreCodec have hard time trying to figure out how to use the HW acceleration but they are trying very hard to improve the situation so maybe with time they will be able to use the HW for now the only way we wan't to watch videos with HW acceleration is only WMP which means recoding or atleast remuxing files.
Cheers
P.S. Could you post exact specs of the .mp4 file? What kind of AVC it was and things like that.

in regards to the WMP hardware acceleration.
is it better on battery life than having coreplayer trying its hard out to render a video. even if its a small 320x vid that plays at 120%. Does that mean that the cpu is running near max?

Video playback

Hi there!
I have gotten to new Lg Optimus 2x now for about a week and I am getting a bit annoyed now. I bought it purely on Being able to play full HD Movies on my Tv. But with countless hours spent on forums and trying with different players, and also differnt types of formats.
What I have on the phone now is QQplayer and arcmedia and ofcourse Lg's player
Formats I have used and there display quality:
.AVI Works in QQ, Arc but not in LG's
.Xvid Works in all
.Mkv (480p) Works in QQ ,Arc but not LG's Also this is where the framerate goes down.... out of sync audio.
.Mkv (720p) Just awfull
I am now converting a 720p movie to mp4 format h.264 to try if that works but it takes ages and I can't be botherd to convert a movie for 4h when I want to watch it on my TV.
So what can be done.. why can it play back some lame teasers on full hd but not a bloody movie in decent quality on 480p...
What should I try to convert movies and episodes to?(prefix)
The phone is not Rooted and I have no experience in that matter
Kind regards!

Because a video is not just a video
Video consist of 3 parts
videopart encoded to some specific format (xvid, divx, mpeg-4, h264, mpeg-2) etc
audiopart encoded to some specific format (mp3, ac3, dts) etc.
a container (avi, mp4, mkv) etc. that encapsulates the video and audio part
furthermore the video and audio part are not just encoded in specific formats, but according to specific settings - often called profiles. These define things like bitrate, b-frames, ref.frames, and other technical stuff
The chipset only support hardware acceleration (which is needed to play video in high resolution) for certain types of formats, and only when encoded after certain specifications, and only when encapsulated in certain containers, and finally only when being played by the LG player.
Other players cannot utilize the hardware acceleration but rely on software filters like ffmpeg, these give you the possibility to play formats that are not supported by the chip itself or by LG's player by using these software filters. But this also means there are no hardware acceleration to help the playback and therefore you can only play these in standard resolution and/or you can get synch issues between video/audio.
the main format supported by the chip and the LG player is called mpeg-4/h264 - and its only supported inside an mp4 container - mkv are not supported.
The encoding of the video part mpeg-4/h264 are only supported up to a certain profile level - meaning it only support upto a certain bitrate, a certain number of ref.frames, of b-frames etc. It also only support certain audio formats, mainly aac. It wont play your downloaded 720p/1080p mkv with ac3 or dts audio, and a videotrack using h264 profile level H4.1 or more with lots of ref.frames
In short you cannot just throw any downloaded or home cooked video to the mobile and expect it play - it wont. Secondly if you bought it to be a generic HD mediaplayer for these types of videofiles, then you bought it for the wrong reasons. It is not a generic HD mediaplayer, its a mobile phone, with the ability to record and play up to fullHD video - if these comply to the specifications which are supported. This videoability are mainly targeted at recording video of reasonable quality (for a mobile phone) and playing web2 content like youtube HD video which complies to these standards.
Nothing more - it wasnt designed to be your HD mediaplayer replacement
So what to do ?
make sure youre videos are encoded as h264 using max profile level 3.1 and max 10mbps bitrate - using an AAC audiotrack and encapsulated in an .mp4 container. Then they will play in HD resolution.
Now all you need is reading a couple of hundreds websites and guides on how to check your files for these specifications (mediainfo), remux video from an mkv container to an mp4 container if the video and audio inside are allready compliant, or how to reencode to desired specifications if they are not compliant.

Very usefull mini guide into the jungle of video/audio, codec, splitters and containers.
Knowing this makes it easy to setup DVDFab and other rippers/converters (hopefully).
Thanks

I tested some h264 formats on the LG2x. Baseline profile works fine for 1080p video, I tried that up to 10mbit/s. Main profile works, but is too slow on 1080p and I think 720p also. It might work with SD resolutions, but I didn't test this. High profile simply isn't even recognized by the LG media player. I did try all profile levels, it ate all of them. Perhaps someone else can figure out the maximum bitrate the device will play smoothly, and what the "maximum" resolution for the main profile is (and at what bitrate).
So if you're putting h264 HD material on there, put it in an mp4 container with AAC audio, and use the baseline profile. 10mbit/s worked fine for the 1080p source I tested with (Looney Tunes Short Fur of Flying).

Hrms, can an app do this? Like for instance, on a desktop/laptop, Window's default player is not the greatest- however, here comes VLC player & it damn plays anything. My point is, can there be a App out there in our future that does this too for Android?

An app on Android can not use the hardware acceleration! On a computer however, a program (like vlc) is able to use your full power!

Hi all
Read this guide "How to make videos to Optimus 2x using Handbrake"

Hi.. THX that is great help.. Very interesting.... .
Do you think that we can expect some 3rd party video player using hardware acceleration of Tegra 2 in Market soon.? Playing .mkv and other HD formats.? Or it is not possible.?

I do not know, but if Tegra 2 will be used in other phones than Optimus 2x ... drivers might be upgraded to support more video types.

An app on Android can not use the hardware acceleration! On a computer however, a program (like vlc) is able to use your full power!

RAWrrrRRR!! WHY?? Okay, I kinda get it thanks...

Its a fact that HW acceleration can only be used when/if Nvidia Tegra 2 drivers supports it.
But any app can play any format if it have the right SW decoder (using CPU).
Optimus 2x should be fast enough to play quality video (DVD resolution 720×576) using sole SW decoders
Isn´t Full HD on a mobilephone a total overkill and kind of waste?
If I want to se a movie on my Full HD Flatscreen I use my Media Center or BluRay player

What kind of movies
YouTube videos ?

Hi Mittaa,
how does it work with big files..? You can only put files up to 4 Gb on the SD card can't you..? So there is not enough room for 1080p movies..???

As I said ... "Isn´t Full HD on a mobilephone a total overkill and kind of waste?"
FAT32 SD card can't handle files > 2GB
Maby you could split files and maby Android supports filessystems other than FAT16 and FAT32 ... I don't know

I think it is not a overkill. I don't have any way of getting HD content on my TV (BlueRay, Playstation, etc) so i can sure use this.
Or when I travel I can just plug my phone to the TV in the hotel room and watch the movie.

I agree. This phone has the specs to run it, & space is up to the owner to use. I remember a headline from Engadget stating that the "the 2X has a crazy amount of codecs for video media" when it's released in S. Korea. .mkv is probably the most popular container for HD videos- disappointing the 2X does not support this...

How is it possible to play 1080X1920 on a 480x800 screen?
It might be possible to use 1080X1920 when using HDMI mirror, but then how much space do you have on your phone? And do you want to split files > 2GB?
OK ... if you use hard compression file size drops ... but then quality also drops to something that you can compare with DVD resolution!
What I ment was that I personally prefare a lower resolution in a good quality
DVD resolution 720×576 ajusted to my phone (MPEG4) take up about 1-2GB and I use to have around 6-8 good movies on my 16GB SD card.
I too hope that more formats will be supported ... at the moment its just not good enough ...

optimus 2x supports baseline profile 4.1
basically it means that most of the 720p media files you'll find in the internet won't play smoothly because they are encoded according to high profile or even have been encoded after specifically more quality wise settings
if you need to encode for 2x you basically need software such as handbrake, set on the iphone and ipod touch profile on the right and change the resolution to your preference up to 1920 width and then set the bitrate so that the maximum won't go over 20Mbit
basically avg 15 would be fine though because of the fat32 limitations 4 gigabytes, it would be wise to calculate the bitrate according to the maximum file size
i do not know if Android supports ExtFat, which supports much higher filesizes, but because of the baseline profile limitations it doesn't really make any real difference between 1080p 15kbit/s or 5kbit/s video stream nor does those additional settings in Handbrake software
there is no "almost lossless" settings for optimus 2x, only thing matters is the speed for reencoding the bloody internet
