Dropping frames w/ 2K footage on Mac Pro

[Bret Williams]

Nah, I can look back at FCP posts to see what days I was and wasn’t working. 🙂 Or at least when I shouldn’t be billing!

Another gotcha, do you have the waveform playing during playback? Turn that off. It makes no sense, but even with proves you can have problems playing back with the waveform on. Well, actually the bug is that when you turn on live waveform/vecotr, the timeline switches to saying that native footage needs to be rendered. Even if there’s nothing to render. Turn off the waveform and the orange/red bar goes away.

But if you have anything 2k that isn’t rendered, that means FCP is not only playing back a 2k file from a very full unaided drive, but you’re also asking the processor to achieve rt effects on it at the same time? I wouldn’t hold your breath. At this point, your drives are full. They’re not raided. It plays back pretty well. Finish the thing, render it and export.

The footage Red 4K footage transcoded to ProRes 422 HQ at 2K; there is also some 5D footage transcoded to ProRes 422 HQ at 1080p.

So you are mixing two frame sizes in the timeline. Are they also different frame rates (Red @ 24 5D @ 30)?

What would Disk Warrior do? Does it free up space somehow?

The only thing that will free up space is deleting files, but if your files are fragmented that won’t help you much until you completely erase the drives and copy media onto them again freshly (contiguously).

The dropped frames only happen when moving to or from the timeline-native 2K footage to any kind of rendered footage (color corrected, rescaled 5D footage, or subtitles).

How do you have your render options set? You may have them set inefficiently.
