Stuttering playback

Posted by Jon Felix on November 13, 2012 at 8:36 pm

Hi! Re-learning AVID (after 10 years) and all good except that I have stuttering playback from the timeline AND whilst playing sources. PLayback will always start out OK, then start to stutter. Checked everything I can think of: Everything is rendered (in any case, as I said, it does it playing source clips too). The video quality setting is draft: yellow.

Imac 2011 3.4 I7 16Gb RAM The AMD Radeon HD 6970 card …
The drives are a combination of Thunderbolt connected RAID and FW800.

Could the weak link be the FW drives (they’re all G-Tech)? If so that’s disappointing because FCP and PPro would cope fine!

Thanks,
Jon

In the timeline, do you have red, blue or yellow bars in the timecode ribbon for the spans where it stutters? The colors will indicate whether it is the drive, the effect trying to play in real time, etc. If I remember correctly, blue was for drive being unable to keep up.

Thankyou for the reply…. no blue bits .. just red and yellow .. but only on part of the timeline .. other parts have no color bars on top and they still wont play properly. Also of source clips viewed in the source window stutter too.

mmmmmmmmm

What format are you working with? And did you access it via AMA and are trying to edit native, or did you transcode to DNxHD?

Hi August. To answer your question: I do not know (wasn’t my project originally), since everything is off-line (see my other posted problem).

And everything is off-line because I tried to move the project to a faster (Thunderbolt) drive to fix the stuttering playback – assuming that is was the FW drive.

I have lost two days now … won’t be using AVID again in a hurry … back to Premiere and even the beautiful simplicity of old FCP7.
