In editing a short form project in Avid MC 8.4, we are getting a jittery and skippy video playback consistently even though we're watching at half res (green/yellow), rendering often, with a powerful MacPro, and have only one editor working off this media partition on our Facilis server. For client viewing, we are connected to a Panasonic TV through an AJA ioXT. It seems to get bad enough for a need to restart the whole computer, which helps for a short while. Any tips on how to optimize our set up and avoid so many restarts?
More details on the setup:
- MacPro cylinder (Late 2013)
- Processor: 3.5 GHz 6-core
- 32 GB ram
- Graphics: AMC FirePro D700
- OS: 10.10.3 Yosemite
- Avid MC 8.4. Project is 1080p 23.98, RGB 107.
- Media: We ingested DNxHD encoded QTs and some ProRes4444 to a 1920x1080 23.98 project DNxHD 36 mxf. Avid media is on it's own a separate partition from the project, all only being used by one editor at a time with plenty of space.
- Server: Facilis version 6.2, restarted 1-2 times/week, connected out via ethernet.
- Monitor out to Panasonic LCD TV through AJA IoXT HDMI out.
AJA with latest software and driver (install 12.2.1).
AJA Format matches Avid sequence: 1920x1080 23.98, color space YUV 8 bit
*It helps to disconnect the AJA for monitoring, but doesn't completely solve. - Edit: It's short! 30 second commercials, some simple masking and scale/position keyframes.
