In recent posts I have been promoting H.264 as the best video codec for Flash video players. But I have to admit that I couldn’t get H.264 .mp4 files to play in my WordPress blog! It just loaded, and loaded, and loaded … I looked everywhere for answers, got clues and hints but nothing seemed to work. After much testing I found the problem and fixed it. I also fixed my coffee machine but that is another story :)
What were the problems? First of all, the Flash player can’t handle H.264 .mov files. So don’t use them, use H 264 .mp4 files instead as described in my other post ‘Great .MP4 with Compressor and Quicktime‘. Secondly, it doesn’t work if you preview the post using the ‘Preview’ button in WordPress admin! You need to publish your post and check the permalink. Took me a looooong time to figure that one out.
That’s it. I hope it helps.
// UPDATE januari 2010: this blogpost is outdated. Here is a better solution: the new Compressor 3.5 has presets for the Apple devices iPod, iPhone or AppleTV. The resulting H.264 .m4v files also work with the Flash video player. Great quality, no hassle!
