speaking of MP4 H.264 play in Gtablet...I suspect the 512MB RAM is not enough juice so 1080 can't play smooth (choppy) in the device.
I convert most of my movies to 720x480 MP4 H.264 and using hardware encoder to (QQPlayer, VPlayer) play and very smooth play but 1080...very very choppy, doesn't matter MOV, MP4, MPEG4, MPEG2..etc
And Yes, if the 1080 movie length is only 10 or 15s (4MB or 8MB), it will looks good (so you see the marketers show the device capable for 1080)...but in the reality, 1080 movie with 7 min (~1.2GB) plays like CRAP LOL...
I wonder how smooth they can be played in Asus Transformer tablet - but I ended my own saga here by staying with 720x480 MP4 H.264 format - good enough for my kids watching 10 movie in the long hour drive!

1080p is 2Mbit per frame, and is larger than the actual display, so it has to be scaled down to 1024x600 as it is decoded - at 24 frames per second. The mp4 (or other) decode + scaling without GPU acceleration is the problem, not the availability of a couple GB for frame buffers.
At a minimum, rescaling your video to fit the native resolution would probably fix it. Most people just don't want to bother
Ram has nothing to do with it ( well it does but even 128 would work )
Its like schettj said, the GPU accell or CPU accell / Multithreaded decode thats the problem.....Ie....Software is the problem.
I am getting ready to convert some movies to H.264 to play on my View. What are the ideal resolution and bitrate settings for good quality viewing? I was looking at using 720x480(I think this is standard for ntsc dvd) with a bitrate of 768 or 896 for the video and 128 for the audio. Any ideas/thoughts/suggestions?
Hi everyone,
This is my first post on this forum. I am not sure if it is proper to ask my question here. It seems this's a forum for developers? I am not a developer at all. If I posted on the wrong thread I am sorry.
I just bought my Asus Eee Pad Transformer Prime TF201 about a month ago. You see, I am completely a newbie about the tablet things. I have a large collection of Blu-ray discs which I want to put onto my TF201 for watching while traveling around. I found a Blu-ray ripping program (It is called Aunsoft Blu-ray Ripper if it matters) that can convert Blu-ray movies to the MP4 format videos for watching on Android tablets.
My question is: I don't know what are the best output settings I should use with the Blu-ray program There are too many technical terms I can hardly understand. Does anyone here have any video conversion experience for Transformer Prime? Any advice or instruction is highly appreciated!
Detailed info about the settings in Aunsoft Blu-ray Ripper software:
Format: H.264 Video(*.mp4)
Video settings available are:
Codec - h264
Size(pix) - original; 1280*720; 1440*1080; 1920*1080.
Bitrate(kbps) - original; 4000; 6000; 8000, 10000; 12000.
Frame Rate(fps) - original; 12; 15; 20; 23.976; 24; 25; 29.97; 30.
Audio settings available are:
Codec - aac; ac3.
Sample Rate(hz) - 22050; 32000; 44100; 48000.
Bitrate(bps) - 64000; 96000; 128000; 160000; 256000; 320000; 640000.
Channels - Mono; Stereo; 5.1 channels.
So I haven't done any converting myself, but I think I can help. Ill just go through those settings you listed and give you what i think would be the best choice.
video-
size- 1920*1080 should work since the prime can handle hd
Bitrate - not sure on this one I would imagine that you could go pretty high like 8000-1000
frame rate- 30
Audio-
codec - aac
sampe rate - 44100
bitrate - (idk on this I think anything is fine) 256000
channels- doesn't really matter the prime will only play mono from its own speaker, but if you hook it up it might be able to do more so maybe 5.1 or else stereo
Hope this helps
If you have a large collection of blu-rays that you want on the Prime, then storage space may become an issue, even if you get a micro-SD card. You could try the suggestions made by cmat1120 and see how many GB a single movie takes up. That will help you determine how many movies you'll be able to store on your Prime.
If you plan on watching movies with headphones, I'd recommend going with a stereo audio output. I don't know if 5.1 will do you any good because I don't think that surround sound gets passed through the HDMI port (I haven't been able to get it to work, anyway), and the extra audio channels won't improve headphone quality.
I also recommend going with original frame rate. I don't see a need to change it, and I especially don't see any reason to increase it above the original. That won't magically give you extra frames that don't exist in the first place.
If you're aiming for 1080p HD, then it is 1920 x 1080 with 24 fps. That's where I would start, and I'd adjust the bitrate depending on how much storage space I want to use per movie; a higher bitrate will take up more storage space but will have better quality.
After thinking about it some more, I am changing a recommendation - go with 1280 x 720 resolution. The Prime's display is 1280 x 800, and some of those 800 pixels are dedicated to the bar at the bottom of the screen. The Prime cannot display 1080p on its own screen. If you rip your movies at 1920 x 1080, the Prime will scale it down to 1280 x 720 when it displays it. I don't even think it can display 1080 through HDMI; only 720. Shrinking the movies down to 720 when you decode them will spare you a chunk of storage.

It can display 1080 via HDMI, assuming your content is 1080 of course. I'd still go with 720 though.. Personally I can barely tell the difference between 1080 vs 720 up-close.. I have trouble distinguishing the two from 8-10 feet away, and the TFP will only display 720 if you're watching on the tablet.
.mkv 720p
although 1080p isn't a problem either, with dice player you just resize it to fill your screen
and bitrate above 160 if you hear the difference on this device I want your ears
Thank you all very much for your inputs here! Really appreciate.
I've tested with the 1080P settings that cmat1120 suggested to convert my Transformers BD of 2hrs 23min. Guess what? The generated MP4 file is 10.28GB! Although the file played flawlessly with surprisingly good quality on my big computer screen, the huge file size made my Transformers Prime tablet a little it bit hard to cope with.
The 1080P settings generates too huge file. In this way my tablet will only be able to store 2 or 3 movies.
I've also tried to use ac3 5.1 audio settings, but the converted file played without sound on TF201. I think ac3 5.1 makes no sense for Transformer Prime as it will only to be able to produce stereo sound.
I then tried with the 1280*720 settings and the generated file is more acceptable with good quality on TF201. The final file is only 4.14GB. This way my tablet will be able to hold about 6 or 7 movies.
The detailed settings I used as below:
Format: H.264 HD Video(*.mp4)
Video settings:
Codec - h264
Size(pix) - 1280*720
Bitrate(kbps) - 4000
Frame Rate(fps) - 24
Audio settings:
Codec - aac
Sample Rate(hz) - 44100
Bitrate(bps) - 128000
Channels - stereo
The 720P settings also converts faster in the Aunsoft Blu-ray Ripper. So I think I will use the above settings for my future conversion.
But if there's any way to make the final size decreases to 2GB around while still keeping the good quality...
Thanks again cmat1120, jkvato, namebrandon and Hawkysoft !
I use DVD Catalyst. It is the best ripping software I've found. It has a bunch of pre-sets for many devices including the Prime. These pre-sets are also set-up for whatever resolution you are looking for from SD to Blue-Ray. This program also has the capability to remove the black bars from certin aspect ratio's. I personaly have not ripped any Blue-Rays but there is a pre-set for HD.
The people who make DVD Catalyst are great at answering e-mail for any problem or question you have. They usually answer within a few hours.
Highly recommended

I use DVD Catalyst as well, and it's a pretty good program. The downside is that in order to rip blu-rays you also need to buy additional software to decrypt the blu-ray, such as Any DVD HD or DVDfab Passkey for Bluray.
I used DVD Fab HD Decrypter to rip the Bluray to hdd then Handbrake to encode to .mp4 (use the ipad preset). Resulting file size has been fairly small. Puss In Boots.mp4 was < 1G. Other movies have been approx 2G or less.
It's not a one-step solution but both apps are free and both apps work on Linux as well as Windows.
THANK YOU FOR MORE INPUTS HERE!
I find Handbrake is very useful to reduce the file size while keeping relatively good quality.
The generated MP4 file from Aunsoft Blu-ray Ripper using the 1080P settings is around 10GB. After using Handbrake to convert again to the iPad format it is now reduced to 1.3GB. Great
The 1.3GB file is now in the .m4v format with resolution 1024*464. It played fairly well on my Transformer Prime and much better on my sister's iPad 2
Also I find if you reduce in Aunsoft Blu-ray Ripper the video bitrate(kbps) value to 2000 the generated H264 MP4 file can be even smaller! At 4000kbps it is 4.14GB, but with 2000kbps it is only 2.14GB and the video quality is still quite good. Surprise
So it seems the video bit rate is the main factor deciding the final file's size.

now try to compress it to mpv, 720p and tell me the output ;-p
720p is better than 1080p for the prime, also reduces size, although 1080p isn't a problem either for me.
p.s. the movies i watch are roughly between 4 and 7GB
Series at the otherhand are mostly between 1.5 and 2.5GB makes sense cuz of the time huh?
p.s. i checked the program you use, and it should support mpv compression as well
"now try to compress it to mpv, 720p and tell me the output ;-p"
Thank you Hawkysoft!
Did you mean the MKV format?
I could not find the MPV output format in Aunsoft Blu-ray Ripper

ah yes sorry... thats what i ment yea
I just tested with the MKV 720P settings from Aunsoft Blu-ray Ripper and the generated MKV is only 1.52GB! Fairly good size and quality for my Transformer Prime. But my sister's iPad 2 did not even accept the MKV file. You see, my Transformer tablet is better than iPad
The Blu-ray movie I converted with is Toy Story 3 of 1hr 43min long. With the program's CUDA acceleration the conversion only took 56 minutes. Very good!

Format: MKV HD Video(*.mkv)

Hi I wanted to know if it is possible to improve to improve audio recorded during a video??
I mean I can record video at 720p 25 fps, but the DAMN audio gets recorded at 12 kbps!!
It's just tinny and annoying sound cuts up all the time.
So it is it possible to increase the bitrate of audio via modifying some system file or changing some parameters in phones hidden settings or something like that?? my phone is a Chinese Zopo PILOT ZP100. Thank you.
btw, When I use Sound / voice recorder, it records in 3gppp at high setting with 127 kbps AAC audio.
https://play.google.com/store/apps/details?id=rubberbigpepper.lgCamera&hl=el
some users with the same problem on other phones use this app with AMR_WB encoder selected and they reported a significant audio quality improved during video
Try it, it might work
Thanks mate. this actually CAN record high quality audio but the video even when selected to record at 30 fps , reciords at 10-11 fps, I guess its my Class-4 card...
Perhaps compare the data rate required to store video+audio data compared to audio data only, and also account for the lower transfer speed of a class 4 SD card compared to class 10. There might be other limitations as well - if a product is sold as a mid-range phone the picture quality may be deliberately downgraded compared to what the hardware is capable of. Samsung galaxy ace 832MHz arm CPU with class 10 SD card = 320 x 240 video recording

when I use native app to record video, it records with bitrates of 11,000+ and 25 Fps! Just that audio is ****ty 12 kpbs!
With the lgcamera app as I reduce the video bitrate the fps goes up so I think it is a bandwidth issue only but then the native camera app can handle such high bitrates....!

try to find out what encoding is used for 720p in the stock camera app, and make sure it's the same in lgCamera.
with the wrong encoding settings your phone may fall back to software encoding, which is much less efficient.
my phone for example is capable of 30fps 1088p video recording, but using software encoding(hw en/decoding is broken in the rom i use) it can only reach 30fps on 480p, or 720p if i overclock.

Don't know, I guess the free version is capped at 20 FPS cause no matter what parameters I set frame rate doesn't go past 20 FPS...
The default encoder for phone was H.263 in 3GP container. still it doesn't make any difference. I was thinking about editing the Media_profiles.xml in ETC folder but it's not even there!!

Hello,
I have Zp200 and I have the same issue about audio quality... and Lg cam software does not work properly (sometimes close and lock the phone during record).
Do you have any new about how to change this bitrate?
Thanks, Caio.
If i wanted to watch a movie what's the maximum BitRate can I run? for example my macbook can't run anything above 35Mbps while my Note 10+ can run up to 75Mbps so far ( i have not tried anything larger than this so far).
You can see the max supported bitrate of all video decoders on your device by Media Codec Info.
For my Tab S5e, the max bitrate of hardware accelerated Qualcomm video decoders is 100 Mbps (HEVC, AVC, VP8) and 60 Mbps (VP9). But, I have no problem to play 4K, 10-bit test videos with 200 and even 250 Mbps bitrate. See some video bitrate test files here:
