Multiclip editing is choking during playback
Hi,
I just created a mulitclip using 6 angles and my computer is choking on playback. I just went and bought 4 more gigs of ram (totaling 6) to try to fix the problem and it’s the same as when i had 2 gigs. I’m playing back 720p prores 422 HQ. Does anyone have any tips. And my settings are on unlimitted and dynamic.
Thanks so much -

What type of hard drive subsystem are you using? that is, what type of drives, and how many are stripped together? That’s more important than RAM.

Hey david,
I’m using a Media Vault that has 10 drives. Its a fibre channel. Raid 3. It’s got 2 terrabytes of storage though theres 485 gigs left. -
That should be fast enough, but you should run a test to check the throughput. Do you have either the AJA or Blackmagic drive test? If so, run some tests and see what your numbers are. Its possible that your throughput is just not high enough for the number of streams you’re playing back in multicam. If not, your drives may be too full or some other issue is causing a bottleneck.

I’m using an aja kona LH but i don’t have a drive test. It would be ashame if the guy recommeded all this ram, which isn’t making any difference instead of putting that money towards another drive to back up some of the other projects onto. Does all this ram even make any difference with final cut?

They are both important, but if the drives are not providing the needed throughput your system will be hamstrung.
Your AJA Utilities which gets insatlled in your Applications Folder has the AJA System Test. Run that a few times to test your hard drive throughput. After opening read the help files to mkae certain you run the proper tests and report back…
