Multiclip Playback Trouble

[Cody Walters]

I didn’t have the realtime scopes displayed while I was playing the multiclip. I’ll try turning them off, if that helps anything in the background.

I’ve been considering a RAID solution for all of my footage. Is this something I can do when I have files on the harddrive currently?

Does anyone else have any speculation on why I can’t play back this multiclip? I would also be curious to hear from someone who edits multiclips with three DVCPROHD clips or more and their hard drive or RAID set-up.

I have done 2 camera DVCPRO HD 720p on a single internal drive, and two camera prores 422 on the same drive. And ProRes has a higher data rate. 3.0Ghz MacPro.

Dunno why you can’t.

[Cody Walters] “I set it to dynamic as well and it is still choppy. I’m watching my activity monitor while this is playing back, and under disk activity the data read/sec reads to a maximum of 35 mbs. Is this normal? “

If I am reading this correct…no, its not. Even a single internal SATA drive should give you more than 100 MB/s.

Are you saying you had four clips in your multiclip? I have three clips in my multiclip and still can’t figure out why it won’t play smoothly.

I am having a similar problem, and have gone through lots of attempts to fix.

Here’s my story:

1. Started out with a 4 camera HD shoot
2. Created Timecoded multiclip
3. Playback stuttered after a few seconds of playback, although it was being played from a three-drive RAID array
4. Transferred all footage into a proxy version in H.264, hoping lower data rate would enable smooth playback
5. H.264 wouldn’t play back multiclip at all, now, the canvas plays back while the multiclip is completely frozen. The image updates when playback stops.
6. Thinking this might be because of the H.264 codec, I generated a ProRes 422 (proxy) version of footage, re-linked, and it still is doing the same thing.

“Multiclip Playback” is enabled.

Any ideas?
