Default 1080p Video Testing for Nook Tablet (MP4)



I've uploaded a suite of 720p and 1080p MP4 clips to test for video playback performance. All are made from the same clip (the hunting scene from Avatar). These should be playable with the standard video player.

http://mediafire.com/?depxt4zyvpwel (download folder)

The clips progress from easiest to most demanding. The "min" clips use baseline profile, low bitrate, and minimum compression. The "avg" clips reflect typical scene rips, with medium compression settings and bitrate. The "max" clips mimics worst-case scene rips with max compression settings and level 5.1 setting. The last clip is the original BluRay clip.

clip_720p_min.mp4 - lightweight rip, baseline profile, L3.1, RF23, Ref1, veryfast preset, 7.7Mbs avg
clip_720p_avg.mp4 - typical scene rip, high profile, L4.1, RF21, Ref4, medium preset, 8.5Mbs avg
clip_720p_max.mp4 - worst-case scene rip, high profile, L5.1, RF20, Ref16, veryslow preset, 9.1Mbs avg

clip_1080p_min.mp4 - L4.0, 14.8Mbs avg
clip_1080p_avg.mp4 - L4.1, 16.9Mbs avg
clip_1080p_max.mp4 - L5.1, 18.7Mbs avg

clip_1080p_master.mp4 - master BluRay clip (2-part rar), high profile, 31Mbs avg, 45Mbs peak


The hunting scene is a very intense scene in Avatar and is a good stress test. Per the bitrate graph of the 1080p_max clip below, it has two peaks, 32.5Mb/s @ 0:44, and 29.1Mb/s @ 1:12 (these are when the shot beasts take a tumble into the mud). If frame-drops happen, they would be at these two spots.

Please try any clip you wish to test, and give feedback on whether playback is smooth with no frame-drops, particularly at around the two "mud splashes."

Using stock Nook video player:

Avatar_clip_1280_baseline.mp4 - Looks good, sounds good.

Avatar_clip_1280_high_5.1.aac.mp4 - Video looks good, no audio.

Avatar_clip_1920_baseline.mp4 - Looks good, sounds good.

Avatar_clip_1920_high.mp4 - Looks good, sounds good.

I can't say for certain what frame rates I'm getting, but it isn't choppy. The 1280 clips might be a bit smoother than the 1920 clips.

  • 1280_baseline - all good, full fps
  • 1280_high_5.1.aac - full fps, no sound at all
  • 1280_high_mp3 - full fps, no sound at all
  • 1280_high - all good, full fps
  • 1280_main - all good, full fps
  • 1920_main - all good, full fps
  • 1920_high - all good, full fps
  • 1920_baseline - all good, full fps

So it can play full hd no problem, but it doesn't like aac/mp3 audio or 5.1 channels?
Devices:
HTC One X (Int'l version) (Samsung - FIRE your designers!)
Nexus 7

Use "thanks" if my post helped you

@DarkDvr

The Android spec for MP4 only allows stereo AAC. 3rd-party video players can play any audio format via ffmpeg software-decoding. But that may invoke software-decoding for the whole video, which means no more smooth playback.

I've reuploaded a revised clip suite to better fit the 4430's performance. The ramping of challenge is more gradated, so you can more precisely determine the NT's video capability.

e-mote, can you suggest the app for encoding for Nook compliant formats and some settings example for that app. Much appreciated.
