So I just converted my first blu-ray to play on the tablet and it looks a little pixelated. Did I use the wrong settings or is it the program I'm using for conversation?
the outputted .mp4 has the following settings:
Video
Frame Width - 1920
Frame Height - 1072
Data Rate - 2496kbps
total bitrate - 2624kbps
frame rate - 24 fps
Audio
bitrate - 127kbps
channels 2
audio sample - 48hhz
I set the program to export for Android Tablets 1080P. They don't currently have the Samsung 2014 as a listed model yet, I did see the Nexus 10 which has the same resolution but oddly enough it wanted to do 1280 x 720 res.
Why convert?

2624kbps for 1080p file?...
bump up your bitrate. 2500 is kinda low. 3000 is acceptable imo if you're concerned with space. I only use 2500 for videos for my daughter. 4 to 5K should give you a 3-5GB file depending on movie length and how well it can compress.

To Answer your question I'm using Pavtube Blu-Ray Ripper. Looks like its defaulting the bitrate to 2500 (for the target) I'll try raising it and see how that works. Thanks.

Yea what he said ^^^
If your going to use low bitrates then your better off using a resolution of 1280 instead of 1920, generally for good quality archiving any bitrate below 4000 for 1280p is considered low, for 1080p anything below 8000 is considered low, although there are other variables at play which can mean you use less or have to use more.
Obviously I'm not talking about viewing on a tablet when using the above but I thought it would help just to give you a general idea, with tablets having a smaller screen size its going to allow you to get away with a lower bitrate.
Your going to find it easier to get a bitrate close to 4000 when using a resolution of 1280 while maintaining a file size your happy with.
Unless you have a 50" tablet 1080p is overkill :laugh:
I would also recommend handbrake along with a little bit of reading of basic encoding.

It just occurred to me a bit ago that this could be why my 720p videos suck more then the next lesser resolution.
Sent from my PC36100 using XDA App
I have a class 6 and havent seen an improvement over class 2, the video records at a slower speed than your card can handle so it shouldn't matter,
I can backup roms quicker though
thank you for the reply.
so the crappy 720p video was a marketing scam or what?
i love this phone, and i thought the video shot very good till i noticed that it wasnt set to 720p, so i bumped it up thinking it would look even better....lol it looks worse.
Umm lets see:
1280*720 = 921'600 pixels
Assume that the camera records @ 8 bpp (24 bit color) * 24 fps = 921'600 * 24 * 24 = 530'841'600 bps... that is 531 Mbps or 63.28 MB/s.
So theoretically, yes a higher speed media would yield a better quality (note that the calculations above do not take in consideration the CPU and the compression, also notice that the sound is not included). Even at the crappy 12 fps, the required sustained speed is still higher than any microsd card out there.

agreed i have a class 6 micro sd n the video quality still sucks

I think the various codecs and compression make these numbers much less significant, but since I don't know the exact numbers I'm would have to speculate on how much the sd card speed matters.
I have heard that for some cameras the sd card speed can affect video capture.
Probably the way the phone handles the compression is the major cause of choppiness for our phones though.
they compress the video so the crappy class 2 cards the phones come with can keep up, someone would have to change the codec so it doesn't compress it as much.
Hello,
I have gotten this MHL adapter for my Note 2 about 2 weeks ago and it works decently. The problem I have noticed is that when I play GTA 3 or GTA Vice City is that the framerates seem a bit jerky to me. Im not sure if its just me or if its the mhl or if anyone else has this problem. Is there anything I can do to fix it?
http://www.amazon.com/gp/product/B009MJ58OI/ref=oh_details_o02_s00_i00
Dear X-dude,
Same here...
No problem with videos or other apps but games have less framerates when using mhl... I am not satisfied with the performance of game playing using mhl and sixaxis controller on TV Screen... Couldnt find a solution till now... I had same problem with Note1 also...
Kind regards...
Sent from my Amiga Note
MHL is not 'up to par' when playing video games, the fps just can't keep up. Playing videos though will work excellent! I use my N2 all the time to stream and play videos and music on my HDTV, looks and sounds amazing! Video games...not so good....
its not the MHL that is the problem.
the problem is the fact that the device is running in mirror mode. if you're running the TV at 720p as well as the phone at 720p, that means that the GPU now has to render twice as many pixels (ie. 1843200 pixels instead of 921600 pixels). it only gets worse if you run 1080p as it will have to render a little over three times as many pixels. doing that is far too demanding for our overclocked mali400 GPU, which is one of the reasons why it lags.
basically, the only device available at the moment that would have reasonable framerates in mirror mode based on GPU power alone would be the ipad 4th gen. i personally dont like ipads, but hardware wise, they do have a beefy GPU. the adreno 320 can keep up well enough, but isnt quite as quick as the powervr chip.
the malit604 might be able to do it if samsung can optimise the driver if they use it in the s4 next year, but at the moment, the performance of the mali 604 isnt much faster than the adreno 320.

That doesn't make any sense.
Mirroring in that case = Output twice what GPU rendered once. Mirroring isn't involving any extra work to GPU, (not sure about 1080p output, but i guess that all rendered in 1080p instead of 720p then downscales to fit the screen of device, performance-wise its only a tiny amount worse than having 1080p screen on device). But any output (and MHL is included) has latency, when you output videos it is not noticeably because you don't interact with videos, but when playing dynamic game you'll start to notice lag between interaction and game react to it.
It is only applicable to Mirror output, extended screen surely will take part of GPU perfomance, but not half of that - it is depending on what you doing. 3D games is involving much more computing than several layers of 2D in android interface or media player.
Need some technically adequate investigation on FPS drop and MHL latency

I also heard something about that and does the 30hz cause dropped frames? Also im pretty sure my mhl outputs at 1080i and not 1080p which makes a difference?
1080i is the culprit.

Souai is right. If you would like a demonstration, do the following. Install the Electopia game/benchmark. When you start the app you will be asked if you want to run it in WVGA resolution or full screen. Try WVGA first. On the next screen choose 'benchmark' mode. Let it run then note what FPS you scored. Next run the benchmark again in full screen mode and note the (lower) FPS. Next, plug your phone into your tv using MHL and run both benchmarks again and note the lower FPS scores.....see? When plugged into a tv via MHL it is having to work much harder.

Hello guys i want to know why...?
I can download movies that are 720p with great quality like 600mb or less..
Why Android record videos maybe in 720p like 10 seconds and it have 150mb +/-
Mayba 10 seconds be 5mb? O less?

it has to do with the compression rates of the videos.
Some people think the 720p at 600mb are horrible quality but on the phones they look decent, since the screens are smaller, its hard to tell, but but on the bigger screens, not that great.
It just varies on the codec/compression/fps
Yea but as i said, movies 720p in TV or atleast 1080p not exceeds 1GB, and 1GB is like 5 minutes in phone. There is a way to change it?
A bluray movie in 1080p is in excess of 10GB for the video alone. Just because you can pirate heavily compressed videos around the 1GB mark doesn't mean this is the prime quality.
The phone will try to take the best quality video capture that the memory and CPU can handle. That's why you have such large sizes. You're supposed to export them to PC and then compress into whatever format you require.
Honor 8 Pro is an incredible device, which ticks all the boxes. But since it has a 2k display and a v8 engine in it, it chunks on the 4k battery pretty quickly.
If there is some way, we could lower the resolution to 1080 similar to that on S8 and S8+, I think the battery life will almost double!

You can there is option in battery section when needed it automatically lower the resolution !!!
We actually don't know when it gets activated. It would be better if the user is given better control of the resolution! Like to lock the display on 1080 to preserve battery and then to switch the display to 2k while playing HD games or watching VR
Charging time more

like others have mentioned, ideally, we want something we can manually control. like what is found on many other phones with 2K screen... users can manually select between 2k, 1080p and even 720p.
right now, the one under the battery/ power savings... we don't even know when it gets activated... or if it works (coz honestly, i can't tell any diff between 1080p and 2K on such small screen).
Hi,
Although there is a option to lower screen resolution to reduce battery consumption, we don't know when it exactly kicks into play or if it does at all. I suspect it only reduces the strength of the pixels.
We have raised this query in the recent meeting which was held in Chennai. They took it with a nod, not sure if it will be implemented. We did point out as to how S8 and S8+ does it.

You will see when an app which sucks too much battery , during that the pixel will be decreased.
PPSSPP needs this...
Current emui 5.1 low res option are not decrease resolution to 1080p I think. Its just reduce the pixels a bit and automatically activated only on power hungry apps. Logically if change resolution at least your screen will flicker a bit. Dont worry upcoming emui 8 will have option to truly change your resolution either 2k, 1080p and even 720p. I think its coming to our phone in January.

The settings allow you to lower the resolution. I lowered the resolution to 2340 x 1080 and I don't really notice anything different.... Would this increase battery life? If so, how much?
It will definitely increase battery life.
How much will it increase depends on your usage and your apps installed. It should at max give you 10% increase.

Ah thanks. I come from an xperia z3 so been using FHD screens only. I was interested in the XZ1 compact back then and one of the key points from reviewers is that the lower screen resolution(720p) saved a lot more battery vs the XZ1 at 1080p.

I think the misconception is lowering the screen resolution vs a device that maxes out at a lower resolution. Maybe it makes a difference for OLEDs...but for LCD screens, all if the pixels are still illuminated, so there's not much difference there.

Using lower resolutions use less power bc they use less gpu computational power. Youre not saving anything really from the screen itself. Think of it this way does your computer/laptop use more power running resource intensive applications or running idle?

Not that the resolution that saved power. If Sony could put their 3840x2160 resolution display into 4.3" size of XZ1 compact it still would run longer on battery than any 6.5" sized phone from similar battery even with 720p display. Because it's sheer size of screen that saves battery, not the resolution. 4.3" vs 6.5" is hefty difference. One needs more light to make 6.5" display emit light than to make 4.3" one hence one need more power.
Think about it this way, if resolution would matter then XZ Premium and XZ2 Premium would drain their batteries in a matter of minutes with 3840x2160 res displays. Right? But they work almost as long as say Galaxy S9 Plus or Note 8.

It not works like that. When your phone renders picture in 720p or 1080p it doesn't do it sitting idle. It still consumes power when rendering picture 60 times a sec. And its GPU still runs at 200MHz, maybe it needs like 230 or 250MHz for rendering picture in 1440p but is 250MHz vs 200 MHz a huge difference? I doubt it
It's not like 1440 picture rendering needs full GPU power but 720p or 1080p can be powered by idle GPU. Never was, never will. Ask devs in http://forum.xda-developers.com/android/software-hacking if in doubt
In reality ability to pick your resolution for battery life is a gimmick and doesn't really do anything.
There were no proofs that phones live longer from same charge when it's resolution lowered. Maybe it works for constant gaming, like playing games in 720p on a 1440p screen will bump battery life. But in other cases no
Taking only power consumption from the display alone, there is no different between HD, FHQ, QHD. The different is that if a game or any apps(or even system app itselfs) runs at HD, it will need less graphic computational power than running at QHD (once again, its not about the drainage from the display, its from GPU).

in reality, it's bull****. learn how GPU works. Try to ask Google devs if you don't know. They do habitate here, at XDA
It's not like it renders something and then goes to sleep turning cores off as CPU does. Instead GPU renders frame 60 times a sec and uses 203MHz either your resolution is 720p or 1080p. It can't lower frequency to 100MHz magically because it's not designed that way. So it consumes as much power working at 203MHz either rendering 720p frames or rendering 1080p frames.
Hence no battery economy achieved
