Mutli clip editing laggy help
I’m editing some 1080i/30fps HDV music video on my 24-inch imac:
specs:
3.06 ghz processor
2 gb ram
500 gb hard drive (I have about 20 gbs of video)
Whenever I try to use the multi-clip function of MC 3.0 I continually get lag on the clips and they temporarily freeze and skip. I tried anywhere from 3-9 clips in the multi-clip but they all lagged the same. I believe that it is due to my system simply not being fast enough. I was just wondering if anyone else might see a solution to the problem so I don’t have to wait to to start editing until I get back to school in december to use one of their G5’s.

Did you capture as HDV as well? Are you in a Thin Raster project?
You might have some luck transcoding the HDV clips to DNxHD full raster. -
What is the drive connection? If you are trying to pull 3-9 streams in real time from a slow drive, it’s not going to happen. And using a Long GOP source such as HDV also adds compute cycles to the process…

Also be sure to enable playlength so the Avid doesn’t have to “build the pipes” for the entire sequence before playing.

AND…
Make sure you digitized your footage in an ‘M’ resolution. You won’t be able to play multiple streams of HD in multicam mode….

Be curious, not judgmental.

Well this is actually a very interesting project, because the footage was digitized in FCP with the Prores 422 codec, then imported into avid at DNxHD145. The footage still looks good though. For future reference what’s an example of an M resolution?
Thanks for the help,

“M” resolution was a “multicam” resolution for SD allowing 4 streams of video on the older hardware and OS systems. It as a 1/4 frame of the data rate.
I wouldn’t expect 4 streams of DNxHD 145 to play off an internal drive without skipping frames.

Try changing the playback quality setting on the bottom of the timeline. When in multicam mode, make sure its reduced.
