This used to be a tutorial on how to export 720p video from iMovie ‘09 for sites like YouTube or Vimeo. Apple have now added a 720p export option to iMovie ‘09 version 8.0.1, so if this is all you want, you can stop here. Run Software Update for the latest version of iMovie.
But if you have an HD camera that shoots in 1080i, and you want higher quality video output, follow this guide.
Please note that I don’t have the time to answer every comment I get on this post, and I’ve had a lot. Please scan through the other comments to see if someone else has asked your question, and re-read my guide carefully. Thanks.
Since this guide was written, Apple have released Snow Leopard and QuickTime X. This guide still applies, but you will have to use QuickTime 7 (which isn’t installed by default), instead of QuickTime X. QuickTime X is still too limited to be useful.

Note: This guide is for users of iMovie ‘09 and 1080i video cameras. If you have an older version of iMovie (including iMovie ‘08), this guide won’t work for you. If you have an HD camera that doesn’t shoot in 1080i (such as one of the “Flip” cameras, or most digital still cameras that also shoot HD video), this guide won’t work for you.
By default, Apple’s iMovie ‘09 software will only export video at up to 720p, and at 25fps. (This tutorial will use PAL framerates, but if you live in America or another NTSC country, it will still work for you. Just read 30 instead of 25, and 60 instead of 50.) 1080i video cameras, however, shoot 50 frames a second. It is possible to exploit this interlaced format and end up with 1080p video, optionally at the full 50 frames a second. (Note that you need a very fast Mac to play 1080p50 video. You should probably choose either 1080p25 or 720p50. Alternatively, the Sony Playstation 3 makes an excellent 1080p50 video player.)
Here’s how you can get the most out of your 1080i video camera.
