How do I go about these Multiclip Settings?

[Josh Taylor] “Footage: Shot at HD 1080p25 with up to 9 different angles.”

OK…what codec? XDCAM? DVCPRO HD? ProRes? HDV? What?

and NINE angles? you are going to need better storage that what you have.

[Josh Taylor] “Preferably G-Raid Drive as scratch disk: Firewire 800 Type – 2x SATA II – RPM – 7200 – Cache – Up to 32MB per drive”

That won’t work for NINE STREAMS of HD video. YOu need at least a 5-drive ESATA or miniSAS RAID for that. That is serious playback. NINE layers of video at the same time. You need serious playback speeds on your storage, and a G-Raid won’t cut it. Nor will FW800.

[Josh Taylor] “Would the Macbook even be fast enough?”

Nope. I doubt it. YOu might be able to get eSATA to the machine, IF you have one with the Express34 slot. But really, 1080p HD…9 streams of video? You need serious power for that. A laptop and a small drive will not cut it.

[Josh Taylor] “Would it be best to convert the footage? Maybe my sequence settings aren’t right?”

Well, what settings do yo have now? Well, that doesn’t matter, no matter what they are, you can’t do this with a laptop and a G-RAID

Hi Josh,

if you want to edit XDCAM EX this might help you. System requirements should fit those already suiting SD, as XDCAM EX has a bitrate of just 35mbit/s. But even in SD nine streams via FW800 might get difficult.

Right now I’m editing seven streams as a multiclip in FCP. The footage natively is XDCAM EX, but made some trouble in playback. I first had to export the single XDCAM EX MOVs of each camera into one Quicktime Reference File, to have just one clip for each camera, to add them to the multiclip.
Afterwards the Viewer showed the single streams of the multiclip in realtime as usual, but the Canvas wouldn’t show my program edit, saying it still needs to be rendered. Though my sequence settings fitted the footage.

I downconverted the footage to Apple ProRes422 SD and playback worked in both Viewer and Canvas in realtime again, though the bitrate of the ProRes files was higher than of the XDCAM EX files.

But while editing another problem occured. Videoplayback started to flicker, while audio continued accurately. Still don’t know what the problem is. Just found out it’s the same with IMX 50 and that stopping playback and starting again helps.

Thanks for the replies guys!

I thought this would be the case. I think I ay try converting all the files in a low quality format, make the multiclip, and then almost ‘cheat the system’ by deleting the low quality footage and when re-importing, choose the HD version.

Maybe this seems to easy a method to get around it. I will give it a shot! 😀

Thanks again!
