Ok, I've upgraded my system, updated all my software, even the bios on my motherboard.
I am perplexed at why multi-camera mode in cs5 is still not working. Here is my process:
I start a new project
Video settings are
- drag my video clips onto the timeline on different tracks. One at a time.
- sync them up
- nest them
- Enable multi camera mode
- Open multi camera monitor
- Sequence has 2x HDV & 2x AVCHD files
- It will go along fine for about 10-15 seconds, sometimes longer (10minutes), sometimes shorter, then it
starts to get jittery. Somestimes the video just stops, but I can still hear the audio.
Sometimes there won't be any video at all when pressing play in the multi-camera monitor... or it will play but so slowly.
Sometimes I can make it through about 5-10 minutes of cutting and the video will stop, but audio continues. Once this happens I cannot get video back. If I close everything and restart PPro I *might* get another 5-10 minutes where it's smooth as butter... but then it will stop.
So here's my system:
Windows 7 Pro
i7 950 - 3.06ghz
12 gigs of ddr3 1600
2 hard drives in the following config
- 500GB 7200 RPM (C: drive)
- 1TB 7200 RPM (D:)
- 1 tb drive that contains my original video, preview, Scratch, cache, and exports
Graphics card is a Geforce GTX-470
800 watt power supply
During the short time that I'm cutting it's smooth as butter, without a bump. But if I have to stop to go back and fix a cut I will not be able to resume my multi-cam editing. It will just kind of freeze up and nothing except play audio.
GX470 is updated with latest driver
I've tried disabling and enabling the MPE - I don't seem to notice anyhting
I don't have any effects placed on these clips as I'm editing a 4 camera angle concert. Right now I'm just cutting and will crop/resize/color correct/fades once I finish cutting...
What do I do?!?!
I just checked the RAM settings and timing to be sure that they are correct,
which they were.
I just added another 1TB hard drive... Do you suggest that I do a RAID0?
I've never done this before... do you know of a good guide that could walk
me through it?
Take note than with your media, the CPU will be a far larger influence in smooth playback than will a RAID. I have no trouble working with four DV streams from a single hard drive. HDV and AVCHD have the same data rate as DV. But they require a LOT more processing power.
Before you spend the time and money setting up a RAID, try out some DV media and see if you really need a RAID.
I hope this info will help you ,
a weak ago i needed to cut with multicam 2 camera footage format AVCHD , each footage was 1 HOUR Long (1080@50i).
when both footage was on my raid 0, multicam didnt run smooth.
i plug to my computer addtional external hard disk (eSATA) and paste one of the camera to it.
the multicam was running much more smoother , meanning (i just think so ) when each camera is on seperated phiysical HD ,multicam can run faster.
notice that avchd format is quiet complex for any NLE compare to XDCAM or HDV .
Well I added the third hard drive per Harm's link. It seems to be cutting
smooth once again. I have more testing to be done, but it looks like that
solved my issue as of now. I will report back and award answer as soon as I
have a chance to finish cutting this set.
Is there no way to pre-cache the multiple video streams into RAM? I am having the same issue, but have easily enough RAM to cache around 10 decompressed minutes of the multiple streams I''m working with. Looking at the disk and processor activity though Premiere seems to be only requesting footage as I need it...
Are you still having the same problem? I was getting the same results. In my case I am using an external monitor and I had the "Desktop Video Display During Playback" disabled. Once I enabled that setting multi-cam started working for me. I see this was over a year ago but maybe it will help someone else in the future?
