Can we increase our frame buffer rate past the 60 limitation? Other devices have!

UPDATE!!!
links to what i am talking about. Want to change the frame buffer rate.

*What Refresh Rate Means*
With the introduction of television display technologies, such LCD, Plasma, and DLP, and also Blu-ray Disc and HD-DVD, another factor has entered into play that affects how frames of video content are displayed on a screen: Refresh Rate. Refresh rate represents how many times the actual Television screen image is completely reconstructed every second. The idea is that the more times the screen is "refreshed" every second, the smoother the image is in terms of motion rendering and flicker reduction.
In other words, the image looks better the faster the screen can refresh itself. Refresh rates of televisions and other types of video displayed are measured in "hz" (Hertz). For example: A Television with a 60hz refresh rate represents complete reconstruction of the screen image 60 times every second. As a result, this also means that each video frame (in a 30 frame per second signal) is repeated twice every 60th of a second. By looking at the math, one can easily figure out how other frames rates related to other refresh rates.
The important thing to take into consideration is how the increase in Refresh Rate improves, or doesn't improve, the perceived screen image quality for you, the consumer. Let your own eyes be your guide as you comparison shop for your next television.
Is it possible to jump our frame buffer rate up past its current 60 limitation?
I will look for some links, but i know other devices (gtab?) have jumped from 51 to 79. This will make all video and games blow our mind!

Does we have this limit ? And if we have it will not affect any thing the human eye can't see more than 60 fps and the tab screen is only 68 fps so the 60fps limitation will not affect us

[Q] Video watching screen resolution

What's the optimum size resolution for watching videos on Xperia X8
What I mean is that I convert my HD videos into a 320x240 resolution to view it on my phone. I convert because my stock video app does not let me play those "big screened" videos. But both the audio and video quality decreases considerably.
I don't wish to use any 3rd party app to watch those HD videos , rather watch them on stock app (Converting into small resolution saves me disk space as well )
What screen resolution should I use to watch good video quality on my X8 ??
Also , any tip to improve audio quality ?
Specs :
Xperia X8
GingerDx V021
Stock Kernel

you can try on 480*320 resolution at bit rate of 1082(around) and 25frames/second and in audio 93kbps bit rate and 48kHz sample rate.
hope this will help you....
P.S. - you are using a custom rom right? so why don;t use try something like MX Video Player? so far it seems to be a good player on stock 2.1 for me. (just sharing my experience mate )

I watch mp4 videos at resolution 640x360 with the mx video player..

I try convert any blueray film with :
- video : H.264, 480*320, 25 fps, 900 kbps bit rate
- audio : aac, 44100 Hz, 2 channel, 128 kbps bit rate
smooth and clear playing in my x8..
try wondershare video converter.. you can googling it.. cheers..

I'm surprised the Tab S doesn't play 4K files natively

Greetings all,
I played around with this tablet yesterday evening at the BB in Burbank CA. Very nice tablet, great design and of course the screen is to die for. With the venture into 4K, I want my next tablet to be able to handle 4K files natively with hardware decoding. I currently have the Sony Xperia Z tablet.
The Tablet S has the same processor as my Note 3 so there must be something in the code that doesn't allow for 4K playback (I transferred two 4K clips via Wi-Fi Direct to the table; one shot from the Note 3 and one from the Sony FDR-AX100 4K camcoder).
There was a post on most of the major phone sites that said Samsung was demoing a 4K panel in a 10" form factor tablet, with a possible winter release. I'm all over that!
Cheers.

Yeah, I also can't wait for smartwatches that can play 4K video.
Oh wait, no point.

4k on tablets will be very expensive, one they do arrive. But the video quality on such a small screen will not offset the price. It's not going to knock us out of the water. Just like you can't tell the difference in resolution, on small television sets, above 720p

Don't be a douche! I was sharing information that I discovered on a new product, if you didn't like the news, then you shouldn't have commented on it!
I have a 4K TV, 4K camcorder and my Note 3 records AND PLAYS 4K so there's a point for me and anyone else with a positive interest in newer tech.

Sure enough, it won't play them. I also downloaded an LG demo clip from You Tube (2300p !?!) and it refused to play as well. The Tab S recognized the file and correctly displayed the information but no go. Perhaps a firmware update can fix that. The demo Samsung supplies with the tablet is 1600p.

Wouldn't you need something like the Snapdragon 805 for 4k playback?
This is one of reasons I'm not that keen on the Tab S - the CPU spec is not that appropriate for the screen size

Why would you want to play a 4k video file on a 2k screen?

Because I can record it on my note 3, so of course I want to play it on my 2k display since I can't shoot 2k video.
Otherwise I have to watch it at 1080p on my tiny phone screen.
Why do so many people when they read a question immediately have to ask "why do you want to do that" or "don't do that it's stupid".

Lack of real-life experiences and not yet imagining the possibilities. I can understand the "why" question if it is followed by some comment that reveals a genuine interest in seeking knowledge.

The only reason I asked is because the tablet screen is only 2k and 4k won't look any better, but I now understand your dilemma of not being able to record 2k video on your phone.

Youtube now supports 4K video. Is there a way to play these from the native youtube app on this tablet?

The way I do it is download tubemate and it allows you to download YouTube video from 240p all the way up to 4k

4K Android Video Player
Try this app. It is expensive though. It is a player that plays the H265 codec.
Search for the Hoid P HEVC H265 Video Player.

You sure you have the Exynos version of the Note 3?
http://nerdict.com/enable-60fps-fullhd-video-recording-exynos-samsung-galaxy-note-3/
The main differences between the 2 versions are clock speeds and number of core. But there is one thing the Snapdragon version is capable of. It can record videos at 4k resolution (3840 pixels × 2160 lines) at 30FPS (Frames per Second), while The Exynos version can only record upto FullHD 1080p resolution (1920 pixels x 1080 lines).

The Hoid player stutters over the entire video on a 4K sample I took on a S5, For something of that price it performs similarly to MX player which also stutters.

I wad slighyly dissapointed as well it doesn't natively support 4k.
Since this is the only uhd device i own atm, i can just convert 4k to 2k.
But i do understand why you would want it.

it just missing the codecs required... wth samsung... codec also dont want to put on such a nice tab... since it can play the audio and logcat says it missing codec...

I am having same query. I hope Samsung will provide codec to support 4k playback in next firmware update.

Mx player pro reverts to software mode for 4k video. Hopefully there will be a hardware codec soon.

Try Android Video Player.
Works for me with most 4k videos, although it still stutters a lot with some of them.
I'm uploading two 4k videos downloaded from youtube
(viewing directly from youtube you get only 1080p)

Edit: 4k plays with software decoding, so I really don't understand why 'cool tool' tells me cpu is at 90-95% but @ 1000-1300mhz (not 1900!) and still video stutters..
shouldn't cpu be at maximum mhz when video decoding requires it?

960 FPS video recording?

According to this:
http://hispeedcams.com/lenovo-zuk-z2-pro-will-have-960fps-video-confirmed/
ZUK Z2 Pro should be capable of recording video at 960 FPS.
It is probably achieved through interpolation or something, or not at all (see Mediatek and their "[email protected] FPS").
Anyway, when you guys get hands on ZUK Z2 Pro, share your impressions and what the camera is really capable of.

Yeah it is on official site, there is 960 fps but unfortunately resolution is not mentioned.
Something is written in chinese forum that 960fps is not supported yet because there is no ZUI 2.0 yet.
So we will have to wait a little for a review.

hello everybody, as a student very intersted i made a little calcul. The snapdragon 820 is able to encode 4k video at 30fps, ie 8.29 Mega pixel at 30fps. So the sd 820 encode 248 Mpixels per seconds. So at 960fps, it means that you get about an image of 0.25 Mpixel,which is roughly a 480*640 pic. Not bad. However if some Mediatek CPU encode at 1080p 480 fps, and if the sd820 is considered better, then he can encode more than 2.09*480 Mpixel per seconds, which match 720p at 960fps. hoping for some other resolution/fps solutions from ZUI 2.0. But if there is no breaktrough for the camera then 960fps is impossible to reach( this far this speed is only achieved by pro cameras which cost thousands), meaning it's a false rumor launch by zuk for marketing aims. Wait for the reviews is my last advice. tchao

SD 801 was capable of [email protected] FPS already (h264).
SD820 is capable of 28 MPx/s (4K is 8MPx) , so theoretically, it is capable of much more than just what you mentioned. [email protected] FPS is only HEVC bottleneck.
https://www.qualcomm.com/media/documents/files/snapdragon-820-processor-product-brief.pdf
MTK claimed their SoC is capable of [email protected] with the use of a Sony's sensor which didn't even have that capability in it's datasheet.
And honestly, it's been a long time since they announced that and have you seen it ever come true?
The only mobile camera sensor capable of very high FPS up to this moment was Toshiba's T4K82 with [email protected] FPS, [email protected] fps and [email protected]
http://www.androidauthority.com/toshiba-240fps-t4k82-sensor-596203/&ved=0ahUKEwjDx_zy4f3MAhUFORQKHXP1BisQFggcMAA&usg=AFQjCNHi7pL_vdS6wb7F9fnUwtST4ip4IA&sig2=nTEBpX31ZuZS2WzWgj5VAQ
But it never appeared in a phone (or any device really), guess it was not as good as they claimed it to be...
OmniVision's OV13870 is capable of up to [email protected] through cropping and binning. However I have a feeling that they are actually the only one to be honest and admit it is not REAL 1080p. Because every slow-motion recorded with a phone I saw was like of a lower resolution then the file captained to be of. (720p looked like 360p, etc)
In my opinion, 960 FPS video recording is not possible with the mobile camera sensors which are currently at the market... Besides, iPhone always seems to come first with better slow-motion (they introduced 240FPS with a Sony sensor and nobody was able to compete woth that for more than half a year). They haven't even introduced 480FPS yet and somebody claims to have achieved 960 fps? I consoder that highly unlikely.
That is why I am looking for what comes out of ZUK Z2... If it really is a 'scam', then I say that they (ZUK and Lenovo) need to be punished...
Even if they come up with something ugly like frame interpolation.

First samples regarding the slow-motion video recording:
http://www.gizchina.com/2016/06/08/weekend-zuk-z2-pro/
So now it is confirmed - it does not record at 960 FPS. It does not even record at 240 FPS.
It records at only 120 FPS ! 720p is the resolution.. but honestly, it does not even look like 720p... more like 576p.
And the player allows you to set the playback speed... so for 960 FPS they basically play one frame 8 times....
Pretty disappointing...

1080 60 FPS too much noisy

I tried to make a video in indoor light in 4K and 1080, 60 FPS, is there a reason why 4K is much less noisy? I did not think that resolution decides how much noise is there.

4K provides you with almost 4 times the resolution of 1080P thus you will most certainly see a difference in clarity.
In running a quick test, at 1080P on the default camera app, it captures the video at a bit rate of 20.0Mbits per second.
In contrast, at 4K @ 30FPS, it captures the video at 41.9Mbits per second.
So the capture size versus the bit rate is certainly going to play a deciding factor.
But there are other ways to achieve an optimal capture rate @ 1080P.
If Xiaomi gave us the ability to utilize the High Efficiency Video Coding (H.265) and dictate our own bitrate, you'd see better capture rates @1080P.
My only other suggestion would be to seek out a third-party camera application (GCAM perhaps?) and test further.

Is there an app that supports [email protected]? There is no point in recording videos [email protected] if there is 4K, but I like the idea of 60FPS.
