I shoot on an AF100. FCP log and transfer (prores 422) consistently works well for me but randomly a few clips will convert fully, but have 90% of the clip blacked out.
The clips will show up in my capture scratch, in my assets bin, but when i scrub them on the preview monitor after the first 20 seconds or so, it turns black?? Although the clip is it's proper length there is no sound and only black. But the clip previews in full in L&T?
