If you want a guaranteed playable video, in whatever media player, use standard mp4 640x480 under 25fps
Also found this info somewhere when I had my Touch Pro, same applies to our TP2.
Since there have been massive problems playing back video on the newer HTC devices, I thought I'd step in...
Below is a GUI, to ease the pain of getting nicely watchable videos on the Touch HD, Xperia, Diamond and Touch Pro.
Any device with MSM720x chipset should work, just make sure to select the correct video resolution.
I would like to give a lot of thanks to tnyynt for helping me test and find the best parameters.
Current version: 1.21
Instructions:
1. Download
http://gm.mainframe.no/stuff/Encoder.rar
2. Unpack the RAR to a directory of your choosing (on your computer).
3. Run Encoder.exe
4. Select the videos you would like to encode and the output folder, hit "Start!". If you like you can tweak the options, but the pre-set options will produce good video for the four devices mentioned above.
5. Once finished encoding, transfer the encoded video to your device and use
Album (or WMP) to view them.
Do not use Coreplayer and complain about performance! Coreplayer can not utilize hardware acceleration yet and is slow!
If your source videos are SD (DVD, PAL etc), use the default 600 kbit/s or 500kbit/s.
If your source videos are HD (1080p/720p), use 750kbit/s.
Remember, there is absolutely no point to use higher bitrate, because the quality won't really increase and you will use
more battery life with higher bitrate! Also, if you are using less than WVGA resolution, you can apply less bitrate. The approximate formula is (YourWidth*YourHeight)/(800*480)*bitrate. So as example for QVGA you would use 4x less bitrate.
