Merge clips limitation...
Last night I filmed a series of short interviews with models who were auditioning for an upcoming pageant. I filmed them in 2K ProRes which even on my GPU-challenged machine runs fine in HitFilm (unless I have a scopes window open, scopes must eat computing power).
I recorded the audio separately, since I don't yet have XLRs with preamps on my Red.
Syncing is where I'm running into problems. The camera segments clips into 4GB chunks. That means that the long-running interview shot is split into a bunch of files. The first one syncs up fine. The rest don't, and I'm guessing that it's due to the ambient noise; I suspect that the scratch mics weren't able to record the models' dialog cleanly enough for the waveform analysis to find a match because of the ambient noise.
This is one case where spanning ProRes files would be a huge improvement. There's also a fatal flaw; HitFilm won't let me extend the audio track to its full length after I sync it, so I can't use the expedient of lengthening it out and laying the rest of the clips in behind the first one, taking advantage of the first one being synced.
I'm going to see if I can stitch the segmented clips into a single one, stuff that back into the bin, and merge with that...
As an enhancement, I think the merge function should be available in the timeline, I think it would be more user friendly than merging in bins, especially in projects with lots of clips.
