Frame Rate Glitch

Hi,

I was getting a playback glitch on all outputs during rehearsals for a show. Content was sticking at the same time on all three outputs every 3-4 seconds.

Setup was as follows:

2x Mac Pro Main and Backup running 10.8.3 with M365, Vector 150 SSDs
3x 1920x1080p Outputs from X4
Content was ProRes 422 LT 30fps
Cat set to 30fps, x4 outputs set to 60hz.

Catalyst was not reporting dropped frames and I tested content I have used before on other shows with no issues and these had the same glitch at the same time. Having fiddled for a while I set the cat to 60fps. This has stopped the glitch but now the cats timings bars are all over the place and it would be good to understand where this initial problem came from.

Answers and questions on a postcard please.

Cheers,

My guess it's the OS. 10.8.x is a dog performance-wise. 10.6.8 is the OS of champions for the old style Mac Pros.

I am going to re image back to 10.6 with m364 and see what happens then.
