Timecode Question - All Clips Start on Frame 00 or Frame 12 in L&T

Hey Guys,

I did a quick shoot on the AF100 on Friday, and as I'm Log and Transferring everything now, I'm noticing that the Media Start timecode of every clip ends on either frame 00 or frame 12 (see attached image).

It's HIGHLY unlikely that I stopped the camera on the half or full second mark EVERY time, so does anyone know what's up with that? The footage seems fine, I'm just wondering what caused this. FYI, I was shooting 720/24P.

Thanks for any insight you guys might have.

It's because the AF100 records in a long GOP format with a GOP of 12. That means every 12 frames is an I-Frame. All media has to start with an I-Frame.
