Thanx for taking the time to explain that Adrian, I guess I'll select 'quick start' when I convert. I use Quick Time Pro to convert from iMovie to a QT movie which I then upload to YouTube, blip and a few others. My files have been very large, even after following the advice of a very popular vid-blogger. I don't like the resolution that he apparently finds acceptable. But thru trial & error just the other day, I discovered a combo of selections that reduced my file size to about 1/3 size with ok acceptable rez.
Anyway, I was happy about that. Again, Thanx. Some folks on this site seem to have an elevated opinion re: their opinion and so I don't engage the group often. You've been considerate.
