FCP7 Multiclip requires render?
on Jul 2, 2013 at 10:25:10 pm

I couldn't find this in previous posts...

I've successfully used the multiclip feature many times in FCP6. Now in FCP7, a render (green) is initially required once the multiclip is placed on the timeline. I typically use two 90min clips to create the multiclip. When each of the two original clips is placed on the timeline, no render is required as the clip & timeline settings match (ProRes 1280x720 59.94). When the multiclip is placed on the same timeliine, it has a green render.

I don't remember encountering this in FCP6. Am I missing something or is this just something unique to FCP7.

Thanks for any input!

Make sure your RT settings are set to UNLIMITED, and that you have MULTICLIP PLAYBACK enabled. And that the media is on fast drives.

Thanks, Shane. I've done both and a green render is still required when I make a new attempt to place the multiclip on the timeline.

Any other thoughts...?

A green render is fine. Means you still playback at full resolution. Orange is the one of concern.

How is the drive that the media is on connected? Same drive that worked with FCP 6 with the dark green render?

All media is on FW 800 drives; largely the same ones I've used in the past.

I'm receiving only a green render, which I can render for an hour and everything is fine. In FCP6 with largely the same parameters (actually on an older machine; a G5), no render was required of the multiclip except for the effects (dissolves, etc).

I can deal with all this. I'm just trying to understand why now there is an extra step.

Thanks for any thoughts...

Well, did the codec of the footage differ? G5's don't really do ProRes...so guessing you were using DVCPRO HD or some other, lighter codec. ProRes has a higher data rate...10 bit vs DVCPRO HD's 8 bit. It's full raster 1920x1080, or 1280x1080...not 1280x1080 or 960x720. That does make a difference.

And you don't need to render before you start editing. Best not to really.

You're right. The G5 was pre-HD for me. I'd forgotten. However the workflow is the same. I guess what's puzzling is that the source clips sit on the timeline without needing to render, but the multiclip requires it... and I'd never encountered that before.

It really doesn't affect the project at all. It's just one more step. I was just curious as to why.

As always, thanks for your insight and prompt responses, Shane!

[Robert Allan] "The G5 was pre-HD for me. I'd forgotten. However the workflow is the same."

Doesn't matter if the workflow is the same, the fact is that you are working with media that has a MUCH higher data rate than SD...even DV. The same hard drives that you used for SD, won't give you the same performance in HD. The data rates are triple-quadruple what they were before. Playing back multiple streams of video, HD video for sure, requires fast hard drives. Firewire 800 will work for two streams, but you'll get the green render. Fibre, Thunderbolt, eSATA, SAS...those will perform better.

Big difference between SD and HD

Green will play back in real time for editing..

When you are done, you need to collapse the multiclips and the render bar will go away.

You do not have to render.
