View Full Version : What encoding bitrate do you all use for the Droid X?

I was using 1600kbps video and 160kbps audio to do some video encoding for my Droid X. However, when playing back, the audio is out of sync and the video choppy. These are using h.264 and stereo AAC. Resolution is 854x(aspect ratio matching).

The files play fine and look fine on my computer, so the only thing I can think of is too high of a bitrate.

Any suggestions?

I've successfully managed to play 3000Kbps / 160Kbps H264 at 854x480 (exact resolution) without issues.

Generally I use 800-1000Kbps/128Kbps, which works great for me. 3000 was clearly overkill, but I just wanted to know.

I used the build-in Gallery for video playback (which makes use of the hardware acceleration for video playback)

Odd. Maybe a different codec? Did you use h.264 or mpeg?

I used H264

You can try the trailers from the link in my sig for testing yourself. Most of them are done using the Droid HQ2 profile in DVD Catalyst 4, which runs at 1500/160 H264/AAC

This link:
http://www.droidxforums.com/forum/droid-x-audio-video/12117-droid-x-plays-hd-720p-mp4-file-samples-post-need-testing-hdmi-plz.html

contains a few samples of the 3000Kbps testing I did.

For more trailers, you can visit this link as well:

Index of /nook (http://www.tools4movies.com/nook/)

those are full-res 854x480 at 1500Kbps/160Kbps

(the NOOKcolor plays those without any issues, even though it has a slower processor)

edit2: if you use the streaming links (the .mp4 ones), you might encounter stuttering if you use 3G. Connect to WiFi or download the zip-ones.
