[Avid-L2] Re: Center Duration 1 fame 1 frame longer duration than time code calculator?

 

The EDL convention made it easier to see your matchframe edits. In a clean list the previous events out point would match the matchframe in point on the next edit/event. When you looked at the edl it was easier to confirm the matchframe. The "Match" button didn't exist on early linear editors so you had to do a lot of trimming based on the duration the new edit would take place relative to the last Record out point. To extend or pick up an edit was entering the last edits out point for both source and record. Learning the edl first made it difficult for me early on in Avid especially at the end of a sequence where you go past the last edit and you see the frame moved to the left half of the record monitor. The record tc moved forward 1 frame but not the source time code. That was confusing for me at the time of transition to Avid.
