Yes it may sound strange, but now with the upcoming HTML5 features every browser again is playing its own game. Firefox and Opera support only OGG Theora, Chrome and Safari only MP4 and what about IE .. it doesn’t support anything. Than why should we convert to mp4 with h.264 codec?

Because everybody is playing flash

And that’s again very sad but at least the flash players are playing mp4 with this encoding, which is good because this file will be playable under most of the mobiles. And if you have a large video site to support why don’t you convert to mp4 and play it with a Flash Player and give the opportunity to play mp4 on mobile.

Only one file under the sky

Thus you gain to keep only one file – playable under every device?

YouTube and FLV

Now I wonder why YouTube have both FLV and MP4 formats?

Of course if you’d like to be perfect …

Convert every video to MP4, FLV and OGG, but that means 3 files for every video?!
