I am in the market for a new HD camcorder. I tried out a friend's Canon M31 and no matter what video quality setting I used on the camcorder, once I transferred the video to iMovie the edges are very squirmy (I know, not a very technical description). This is most pronounced on horizontal edges. The problem appears when viewing in iMovie and on the finished DVDs played on my TV. Is there a problem with his camera? Are there some camera settings that I need to change? Are there some import or processing settings I need to adjust? I can't believe that this problem is common or nobody would buy these camcorders. I also tried a Sony model at the store as an alternative to the Canon, recording onto my own SD card. Once I got home I found that I could not import the recording into iMovie. I had the same problem with my friend's Canon. Do you have to upload via the camcorder? Thanks in advance for your thoughts and advice.
