If you want to convert a video in a format that can be played back on as much devices as possible, you need to make some concessions. This little tool tries to help with these: You tell it which devices are important to you, and it tells you which formats you can use.
Note that this list is not very detailed. This is deliberate, because otherwise it would be much too complex. It's also conservative: it might be possible that some devices of a category play files in additional formats not listed here. Moreover, there may be inaccuracies; if you find any, please tell me.
Please select the devices on which your video must play:
PC with Windows XP
assume that DVD player software is installed
PC with Windows 7
Mac with OS X
DVD player
DVD/DivX player
Blu-ray disc player
HD media player (WD TV, O!Play, Xtreamer, most Smart TVs, ...)
XBox 360
PlayStation 3
iOS devices (iPhone, iPod touch, iPad)
Web video using Adobe Flash
You didn't select any format yet. If this means that you don't care on which devices your video will play, then go ahead and encode it in whatever format you want :)
