Just started using iMovie to edit video. Latest project was to DVR a movie, record to my DVD recorder/player, rip it to iMac, edit and burn back to dvd using iDVD. The 80 min. movie was ripped using Handbrake. It came to iMac as a 765 MB .m4v file. I imported it to iMovie, edited and exported as an 8.05GB .mov file. It seemed very large. When I clicked on the .m4v version, it opened in FLv Crunch, so I continued and converted it to .mp4, which came in at 4.65 GB. So the unedited movie was almost half the size of my edited .mov. I re-imported the FLv Crunch into iMovie, trimmed & edited to a 1.51 GB .m4v file. I then re-exported that as a 3.66 GB .mov movie. I realize that different formats, etc will be different sizes, but why so much of a difference? The iMovie Events file on computer is 17.49 GB big. Where is the size coming from? The only thing there is that original import of 765 MB? Also, I am assuming the larger .mov files are better to burn via iDVDF than the smaller .m4v files. Correct thinking on my part?
