Importing footage from a Canon 70D DSLR. For some reason, these clips have an "internal timecode", and if I import them into the trimmer, the cursor position doesn't start at 0. They start at around 8 or 9 minutes. It's an easy fix for me, actually, all I had to do in order to fix the issue was right-click on the clip in project media, go to properties, and under timecode select "use custom timecode" and set to 0.
I know the solution, but I'm just curious as to why it happens in the first place. Is Vegas mistakenly reading the date stamp as timecode?
