Use of SLR for video

[Anthony Jukes]

Hi Randy.
One thing you can try is rewrapping the .mts files to .m4v with a free
script as described here
http://vimeo.com/groups/gh1/forumthread:232846

After rewrapping, iMovie is generally happy enough to import the
files. There doesn't seem to be any loss of quality as it's not really
converting, just changing the container. It is very quick.
