    what is the best setting I should use in iMovie 09' for compression? My video is only 6 minutes long and I want to send it via email and I can't be more than 20MB.

    I exported it into a MPEG-4 format and it was only 17MB but the quality was terrible. How can I send a small video and still retain the good quality of it?

    thanks for any tips !!!!

    6 minutes compressed into 20MB is quite bad.
    That's 3.3333MB per minute, 55 KB/s and assuming the video has 25 frames, that's 2.222 KB per frame.

    For that the image dimensions (resolution) shouldn't be more than 320x240 pixel.

    What dimensions has your original video and what resolution shall it have when being delivered per email?

    The most common codec used for this task is H264 wrapped in a .mov or .mp4 container.

    iMovie has several templates to use for exporting video, your best bet might be the one for the iPod touch.

    But you could also export a good quality version with iMovie and the use MPEG Streamclip to re-ecode the video again,, as MPEG Streamclip gives you the option to set the final file size by entering the KB/s, MB/s or Kbit/s and Mbit/s.

    Another alternative is to use a service such as Vimeo. You can upload the video and password protect it. Then instead of sending a bloated e-mail, you simply e-mail the URL and password. The uploaded video can be much better quality than you might be limited to within your 20MB size limit.
