Multicamera editing slow
Hi This is the second time I am using multicamera editing in FCP X. The first time was a good experience. I used two angles and both were HD at 720p. I have not experienced any problems there. But this time as I am working on another show, again with 2 angles and in Standard Definition, the cutting tends to start slowing after I reach 30 minutes and it continues to slow until it becomes unbearable. Can someone tell me what seems to be the matter? I am using an iMac 2.5 GHz Core i5 with 8GB 1333 MHz DDR3 ram and MAC OS X 10.7.2.

Check if you are using optimized media for multicam.
Menu:
Final Cut Pro>Preferences>PlaybackCheck:
– Create optimized meda for multicam clips -
I am using optimized clips for multicam. Infact I start very good. It is only after I reach the 30th minute that the cutting starts slowing down gradually. I split the show in two parts. It happened in the first part, so I stopped, made another project for the second part and I started again. And again after 30 minutes of cutting it slows down.

FCPC still doesn’t like long projects , I’ve been splitting up longer shows into 20-30 minute segments for editing and then Putting them together on final export

Thanks for the tip. I hope Apple will fix this in the near future.

I’m sure they will, FCP classic used to do the same thing in it’s earlier versions

I’ve been having a similar problem with a much shorter project. Was on the phone with Apple 4 times and even sent them files (more about that in another post).
Performance improved quite a bit when I copied the project file to my system drive (event still on external eSata drive). I had understood best practice was to keep both project and event on the same volume. But the crummy performance says otherwise.
So for now, I am back to a FCP 7 approach, with project files on my system and project media on external drives.
It might be worth a try.

I also had the same problem with 10.0.5. so apple did not fix it!!
after 30 min of multicam editing everything slowed down untill no more work was possible
( beachball with every edit , playback stopped , only video cuts no dissolve , no fx
i have to do a programm with 2 Hrs . so i am really angry nowi noticed something when splttting up the rest ( which i hated to do because i wanted ONE timeline )
a similar project was nO problem in FCP 7)i looked at the size of the project files on the disk
30 Min = 107 MB the folder and 34MB just the Current version its got 216 Cuts ( clips)
16 Min = 17,8 MB!! the folder an 3,5 MB for the current vrsion its got 108 Cuts ( clips)SO; TEN times the size for double of time & cuts ,, Something grows very wrong here !! , exponential
BTW 8core 3,2Ghz MAcpro 24 GB RAM SAS RAID so its not the hardware 😉
ON 10.6.8 & 10.8.1 same problemPeter Schroeder

Peter, are you working with compound clips in that project?

I think that the problem is not the mulicamera editing tool. I have worked in HD format and had an hour and a half project and it worked perfect. I think the problem is the kind of file you use in the timeline. In the particular project where I had the problem I was using files that I captured from a tape and files the I had filmed right on to a Hard Drive. When I eliminated the files from the Hard Drive, FCP X started working normal again. So I think it has something to do with the kind of files I was using, even if they were also .mov files.

no compound clips . just straight cuts
its seems to be a strange kind of memory usage
making a new project : copy the first 10 min into the new project : size 3 MB totaL 10 MIN
copying the 10 min 3times into the timeline 3,9 MB total 30 mincopying the next 10 min 9 MB total 20min
copying the third part 18 Mb total 30 min
the original 30min is 34 MB
and even 30 MB should not bend down the system but ist does
