I looked into the reel numbers but they matched. What didn’t match however was the timecode. For some reason as soon as it came into Resolve the starting timecode for those clips was changed to something far from correct (sometimes reset back to 1:00:00:00 other times random numbers like 1:01:50:08). I manually set the timecode in the media pool and it linked up.
Any idea what might cause timecode to change once it hits Resolve? I noticed the clip name was changed in FCP but that shouldn’t affect it.
