alternative to ProRes for RT editing?
I’ve been trying to do some multicam editing of 4 1080 angles. The footage came from Panasonic HDC-TM700 cameras. The clips are 15 min each and about 3-4GB in size.
I used compressor to turn them into ProRes 422 and each clip by itself works fine in FCP. However, as a multiclip, my machine (MBP 15″ i5) can’t keep up. Nor can my desktop Mac Pro.
There’s definitely some bloating going on here in the conversion. The new files are in the 40GB range, so they increased about 10x in size.
Is there another codec I can use for RT editing that won’t blow it up so much? I’m on FCP 2 so I don’t have ProRes LT or Proxy.
thx

DVCPRO-HD should work

Tried DVCPRO-HD and it can’t handle 4-stream multicam of that either. Looking at data rates, I see:
original footage: 24Mbit/s
DVCPRO-HD: 231Mbit/s
HDV: 26Mbit/s
XDCAM: 36Mbit/sI suspect I can handle either the HDV or XDCAM no problem, but looking at the images those two are noticeably softer than the original.
Is there a codec with a lower bitrate that maintains the full 1920×1080 resolution that is also native to FCP for RT editing?
thx!

You can figure out what the file sizes should be with this link.
Can your graphics card handle 4 streams? Can your media drive?
You can edit in prores proxy if that would help.

Since ProRes Proxy is not an option, you might do an old school transcode to Offline RT in Media Manager. Then when your done editing, collapse your multiclips, then reconnect to the original full res files.
The workflow for this is in the manual.

Hi Ben, If you trans-coded a 15 minute 1080p video file to ProRes and it ends up at 40 Gigs you may have accidentally encoded to ProRes 4444.
A ProRes 422 video file, assuming 24p should only be approx 1 gig a minute ie: 15 minutes = 15 gigs. At 30p it would be about 1.3 gigs a minute… or 15 minutes = 19.5 gigs
Now, playing back 4 streams of 1080p ProRes files all at once, assuming 4/ ProRes 422 30p video streams, is going to require a RAID system and would NOT play off of an internal MBP system drive or even an external FireWire drive. You will need something with a throughput approaching 100MB/sec or more.
Hope this helps, Good Luck!Richard Cooper
