multiclip…or is my computer just slow
hey guys (and gals),
i am doing a multiclip edit with 4 video clips I captured from mini-dv tape…I took all 4 clips, synched them to a single sound source, and exported them all as quicktime movies using the default settings and creating stand alone video clips…then I reimported them into fcp and created a multiclip…however when I play the multiclip it plays for 3 seconds then stutters and stops. if I hit stop, the playhead jumps ahead, as if my computer is too slow to handle the multiclip…I turned on safe rt, dynamic for all previews, and my hard drive is connected via my internal sata bus…any idea why this would be? I’m such a FCP noob…thanks for the help in advance… -

Well, what kind of computer do you have ? And I tell you
What harddrives do you have ?Ren

g5 quad and a 500gb western digital internal drive…and the 500gb is only 1/3 full (it is also my scratch disk, but not my system disk)…

No, this shouldn’t be happening. I’ve used multiclip recently on a sinlge G5 1.8 and it played fine. First check your window size settings, then check your scratch disk settings to make sure you haven’t captured to your system disk by accident.

i am importing 4 4.5gb clips into fcp, my scratch disk is my 2nd internal hard drive (not my system disk, and not an external drive)…what do you mean by changing the window size settings…this is so frustrating…
-
I’m not at my workstation right now, so I’m not sure if you still get a ‘fit to window’ option in the multiclip window, but make sure everything is fitting inside the window view and not being cut off. Maybe it does this automatically, I’m not sure.
Also, go into your the multiclip submenu and try different views (try setting it to fewer just to see if it makes a difference).

I have it to fit to window…i changed it to 25 and 50%, no luck…also I changed the view to 9 up and 16 up, and still no luck…it only works in one up view, and whats the point of multiclip with just one window up…are my videos too big in size? I can’t see why this would be happening, especially on a system like mine…I also have a blackmagic decklink pro hd card and with it both on and off, no difference…any other ideas…thanks for your help, its either this or the $800 apple help and for one issue? this is way more worthwhile…

When I got my Quad G5, I installed 4 – 500GB hard drives in a RAID 0 and verified that I was able to get over 200MB/sec transfers from the RAID. The, the first time I used MultiCam, it exibited the same jumpiness of the play head with 5 DV streams. I don’t remember what I did to fix it but, it should not be happening from one SATA drive as they are capable of at least 60 MB/second for each drive inside the G5.
You might try downloading the AJA Speed Test utility and check out what that tells you. http://www.aja.com
If you have the Decklink HD Pro card, then you will need much bigger drives in a RAID to get into that format. True, uncompressed HD requires nearly 200 MB/sec for each video stream.

the clips are ntsc dv…i ran the blackmagic speed test and it reads @ 71.4mb/s and writes @ 44.2mb/s…any more ideas how to play these clips in real time? again, each clip is about 4.5 gb in size…

Ben, have you tried re-setting up the multiclip, just for the heck of it? Do your sequence settings all match your source material?

Ben,
Did you go through that process just to get the same audio on each angle? I’ve only used multiclip a few times but I always did it from the original source clips and haven’t had the problem you’re seeing. You can set the multiclip to use audio from only one angle, it doesn’t have to be set for “audio follow video”. I would try a test multiclip that way and see if you still have the problem. It may be there is some problem with the quicktime movies you created.
Regards,
David
