nexus one video conversion with handbrake

Hi,
Anyone tried using handbrake to do video conversion to mp4 h.264? I'm using 0.9.4 and not having much luck. All i get out is the audio. I can convert to 480x320 resolution on Videora but trying to get 800x480, or something close to that resolution. So i have this video i want to convert and in Handbrake i used the native 720x304 screen size at 24fps. I think i tried 29.997fps too. I am wondering if the bitrate needs to be some specific multiple like 768kbps or 1.5Mbps. Is there a configuration that will work with the Nexus? Thanks in advance.
[update] so i stumbled upon this link that may or may not help.
http://matthodology.com/n1/2010/03/02/convert-movies-for-viewing-on-nexus-one-using-handbrake/
i will try it out tonight and let you folks know.
[update2] hey what do you know, it works! i used the "iPhone & iPod Touch" preset and it looked pretty good. exciting! need to experiment with more videos. follow the instructions in the link and make sure you adjust the width appropriately. definitely don't try a resolution that is over the source resolution, that's just wasteful! hehe

I know the physical sizes of the iPod/iTouch are about the same, but isn't the resolution 2 times less?
Nexus One Resolution: 800 x 400 = 320,000 Pixels
Iphone Resolution: 480 x 320 = 153,600 Pixels
2.08 times less?
It would seem you are not getting near the resolution the phone is capable of.

my problem was Handbrake was saving everything as .m4a. Change your extension to .mp4 if you haven't already done so.

somehow that particular preset works, you can adjust the output resolution in the first tab. from what i'm seeing it seems like it's working. i will use a media tool to check the resultant file's resolution tonight. good point though.

The Windows Mobile part of the forum has a great application that has thus far worked great for me.

I actually just got handbrake set up doing video conversions for the Nexus, but it's at home. If I remember correctly, I used the iPod settings, then changed a couple of values (namely setting the width to 800 by default and letting it keep aspect ratio) and set a preset. Looks fantastic on the Nexus, I'll try to see if I can export the preset somehow when I get home and send it your way.

try format factory... it has a preset for the N1

Handbrake is great , has alot of options, as usual it is only good if you know what you are doing, so we need a preset that WORKS.
right now I'm testing HD Encoder by projection, runnig it on Ubuntu usin Wine 1.2 Beta , well it has ceashed ... will test more.
The good thing is you have just 3 options ... so it's easy to use

Rats, I can't seem to find a way to export a preset, so I'll just try to type out what I set. I know I started with the iPod preset:
On Picture, I have Width = 800, then click "Keep Aspect Ratio" and let it populate height. Anamorphic set to "None", Cropping set to "Automatic".
On Video Filters, everything is set to Off and unchecked.
On Video, Video Codec is H.264 (x264), Framerate is "Same as source", Avg. Bitrate is checked with the value of "1500"
On Audio, the one track is set as Source: Automatic, Audio Codec: AAC (faac), Mixdown: Stereo, Samplerate: 48, Bitrate: 128, DRC: 0.0.
Nothing special for Subtitles or Chapters
Advanced I've got:
Reference Frames: 1
B-Frames: 0
Motion Estimation Method: Uneven Multi-Hexagon
Subpixel Motion Estimation: 6
Motion Estimation Range: Default (16)

CABAC Entropy Coding: Unchecked
Psychovisual Rate Distortion: Greyed, all the way left.

Hope that helps!

how do you like that converter so far? how long does it take you to convert a full movie like district 9? i'm using aimersoft.com and they also have a N1 preset and add subtitles from srt files. you guys can get it free via torrent

Thanks for this.
I am able to export presets, so after I'm done converting "Fight Club", if the settings worked, I'll update my reply with the preset attached.
[edit]
15 hours to encode...fuxit.
The preset (using Swervo's info in the above post) is attached. Remove the .txt extension.

Just downloaded and installed Format Factory... where's the Nexus One preset?! Under Google, there are two for a device called GX... neither with the correct resolution.

Did you find the nexus preset...I can't find it myself

I just use the iPhone/iPod Touch setting, the resolution is lower, but it looks fine and keeps the file size down. I've converted seasons of TV shows and it works great

How long does converting a 700mb video in format factory take.its been 3 hrs and I'm at 72%. Is this normal?

I use to have a BB and I used this guide:

It worked on my BB and it works flawlessly on my N1.

It depends on your computer's specs... but even on my laptop, which is running a core2 duo with 3gb of ram, it takes about 60% of the time of the length of the movie, or maybe a little less.

lol, takes me 7-12 minutes to encode a 2hr movie to 80% of original size

1920x1080 in Webtop 3 (ICS)

Hi,
I been using the webtop 3 on my atrix lapdock and it is really amazing
I connected it to my 37" FULLHD LCD screen and chose 1920x1080 50/60Hz as my resolution but it still looks like 1280x720,does someone knows if it is even possible to output 1080p from the droid 4? (I have seen posts about getting webtop 2 in Atrix to output 1080p).
How does webtop 3 works in terms of outputing,since it is plain ICS there is no X server,right?
Is there any config files that I can play with?

It's just in the normal Android settings menu, though I can't remember exactly where, probably under display.
The option only appears once you have an HDMI cable hooked up, and I don't have one available right now, sorry.

Yep, under Dispaly you can find Webtop resolution and can choose 1920x1080 50 or 60Hz.

I see the option, but it's greyed out for me, for some reason. My TV supports it, but it defaults to 1280*720

I`ve just tried it again, connect to my 40-inch Samsung, choose Webtop, by default it`s 1280x720 - but I can change it to 1920x1080.

are you sure you don't have a 1080i TV and not a 1080p? webtop might be picky between the two.

This is often the issue. A lot of 1080i TVs aren't even 1920x1080 they are 1366x768 using cheap panels originally intended for computer use. See if you can find the actual specs, including the native resolution, of your TV. Or post the make and model here.
In any case the phone will be querying the TV for it's capabilities and offering up whatever the TV claims to support.

It's a 42" LG 3DTV from 2011, according to the LG remote control app on my phone it's a 42LW570S-ZD. As far as I can tell it's full 1080P with 100 Hz (so assuming 50 Hz should be no problem either, but it might be picky about this I guess?)
Maybe I should turn off the smooth motion thingy?
Edit: probably a TV related issue indeed, with my projector it works fine. I can select from the whole list of resolutions even though its native resolution is 1024*768.
Edit 2: Now the selection seems to work, not sure why. Maybe playing around with the projector 'unlocked' it, or maybe it was the smooth motion thingy. 1920*1080 seems to be a lower resolution effectively than 1280*720 for some reason, browser still says it's 720P so still need to search some more. Strange thing: 1280*720 @ 60 Hz works great without 'scale to fit' enabled, but same resolution @ 50 Hz doesn't fully fit in the screen. Enabling scale to fit make everything look less sharp, so the resizing algorithms aren't that great.
Edit 3: There's something very fishy going on here. It looks like it's always based on 1280*720 resolution somehow:
- My TV reports the selected resolution, but anything over 1280*720 looks like it's downscaled (horribly).
- Web pages always report 1280*720 resolution via stock browser, even when I'm in 640*480 and can clearly see the lowered resolution.
- Android Assistant always reports 1280*672 (or something) resolution, which is excluding the action bar I guess.
No idea if that's related to my TV or just a general WebTop issue though. The TV seems to respond to every resolution change, and shows the selected resolution in its info bar.

I chose the 1920x1080 all that I am saying it is that it looks like 1280x720 to me.
My TV is Full HD and I use it with my PC in 1920x1080.
Can it be that it scales the picture to be in the same dimension?

Same for me, and the phone seem to report the resolution being 1280*720 regardless of the actual selected resolution.
Also the downscaling algorithm is terrible, 1920*1080 downscaled looks less crisp than 1280*720 full resolution.
Tonight I want to try taking some screenshots, and see what sizes they get.
I was wondering if it could be the HDMI cable, but it passes 1080p just fine for other devices.

acipio Robt.
The chipset(OMAP 4430) should support full HD display and from what I understand on webtop2(on atrix I think) people managed to display the full resolution.

The proof is in the pudding. I took screenshots at 640*480 (clearly blocky when shown on TV, and TV indicates resolution as 640*480), 1280*720, and 1920*1080..
They all have the exact same dimensions!
The actual operating system is running at 1280*720, regardless of which resolution you select! It's resized by the output chip. Nasty nasty!!
(but understandable, else every resolution change would require some apps to restart, and using 1080p instead of 720p would be less fluid while most people can't tell the difference anyway = less customer satisfaction for Average Joe)
So we need some config file hack to enable TRUE 1080p probably.
Edit: XDA forum resizes the pictures, so here they are in full resolution (click the corner icon to view full) - http://imgur.com/a/2DuqK
Edit 2: Even for WebTop 2, it looks like Motorola never stated it supported 1080p - looks like 720p is max. But for older WebTop versions, a higher resolution could be hacked via the terminal, so I'm hoping to find something similar for WebTop 3. So far no luck in any config file or DB I checked.

Yes, without 1080p (or even 1280x1024) support I'll send back the Razr Maxx inkl. HD Dock BT Mouse & Keyboard. I was testing the Webtop 3 solution to connect to a regular Business Monitor (e.g. 19" and 24") to run a virtual Win7 Desktop via Citrix Receiver over that - but with a limit at (true) 720p this is no acceptable solution for me.

Chromecast tab cast resolution

Hey guys!
I've been playing around with my Chromecast after I got it today, and everything seems to be working great. Except when I cast tabs (or the whole desktop) to the Chromecast, somehow the display gets cut off by like a couple of inches on each edge. I tried with a Macbook Pro, and a Win 7 desktop (varied the resolution on the computers as well). I have a Haier L32D1120, wanted to know if anyone else is having similar issues. I tried the different options under the Chrome extension, none of them fixed it. I use a PS3/Roku/Apple TV on my TV using HDMI, and none of them have any issues like this.
Any clues?

I'd expect them to handle some overscan, but without some sort of setup util to determine (via user input) the optimal amount, you're likely to still have some. Does it provide a setup in the beginning asking you to move edges of a box or arrows until they are at the edge of the screen (overscan calibration)?

I looked at the advanced video settings on my TV, and somehow the Overscan setting is set to On, but it never lets me do anything in that option or change it. Weird. Might have to look at the manual.
Thanks though.

I think it's the TV that is doing the overscan, since it's an HDMI signal, not a Monitor input like VGA or DVI. So it's interpreting that the signal has been adjusted to be overscanned. Idunno.
Anyway, My TV (Samsung) has an option to adjust the fit of the picture
Menu > Picture > Screen Adjustment > Picture Size > Screen Fit
Now I can see the entire video and no overscanning.

Yeah. Overscan isn't accidental. The reasons may be ancient and a result of inexact control and display, but all modern "TV" displays will scale/crop some of the signal (overscanning) to deal with the format of the signals that had to be padded for displays that had no choice (CRT).
That's pretty much THE defining characteristic of a TV vs a "Display". These days, any decent digital TV can display 1:1 pixel ratio (like yours).

Waze not filling the full screen ?

Hi
I bought T325 and i wanna use it as a big GPS (when i'm passenger, it's more funny than watching video while wife is driving)
So i tried Waze. Working fine on all my FullHd devices, but not with T325 2560*1600. Screen is not fulfilled.
Waze is not screen resolution compatible atm with T325. Porbably app will be updated in the future, devices like LG G3 are coming with huge resolution.
Is there a way to solve this problem for the moment, modifying DPI for example ?

I have lot of white squares on the map using WAZE SAMSUNG TAB PRO 8.4" SM-T325 on the corners or at the top and the bottom! How can it be corrected?
youtube.com/watch?v=wn1AU0qziow&feature=player_detailpage

I've just bought a glaxy tab pro 8.4 for the specific reason to use waze ( i'm a taxi driver ) to my horror i'm having the same problems as described here. I had a tab 4 7 inch and it worked fine. Please be a solution for this, is there any way around this?

Guys, haven't received my T320 yet, but try fiddling around with 'Xposed' + 'App Settings', some DPI change or fullscren force would probably resolve this.

Sorry to resurrect an old thread, but Waze still has yet to fix the rendering issues on higher res screens. I've played with a bunch of settings in X App Settings and nothing seems to help. I think we'll have to wait on a fix from Waze

Determine present resolution

I have a chromecast hooked up to a pretty old TV via HDMI. It's working perfectly and the TV tells med it's running at "720p, 60hz". My problem is that when I hook up my computer (nvidia gtx 960) via HDMI to the same TV I have to set it to 480p for the picture to be stable. At 720p it starts to flicker and go black on and off. I have tried many different resolutions with varying result. I don't understand why it works with chromecast and not with the computer, both at 720p.
That's why I was figuring if there is a way to tell at exactly what resolution the Chromecast is playing. Perhaps the Chromecast have determined an optimal resolution for the TV that I havn't yet tried with the computer. So is there a way to tell the exact resolution if I root my Chromecast?
Thank you

1280 X 720 60Hz is standard 720P.
If you look in your nvidia control panel (which is what you should be using) there should be an indicator of what the native resolution of the monitor is.
1280 X 720 or 1176 X 664.
Don't try to set resolution from Windows itself on an nVidia card.
You may also need to set desktop scaling if your monitor's bezel doesn't support underscan.
You should also do that in the nVidia control panel.
If you have that installed simply right click on the desktop and there should be a link to it in the menu.
