Kona LHi, FCP & 720p
I have a octo intel mac with 8 gigs of ram and the latest version of FCP and a Kona LHi with the 8.1 drivers. I use a xserve raid and an internal raid for media playback. Ok so here’s the deal.
If a project has a 720p prores sequence with a 59.94 timebase, I can’t playback the sequence without turning off mirror to desktop. If I try to mirror to desktop the sdi signal to the external monitor drops frames and goes way out of sync.
If the 720 sequence has a 23.98 timebase, everything is fine.
1080i or standard def dont have this problem. Thoughts?

So your video output to set to 720p 59,94 10bit?
What kind of drives are you playing back from?

[dan luke] “I use a xserve raid and an internal raid for media playback.”
So which one is this 59.94 material on? Why two?

this stuff is on the xserve. I have 2 to maximize storage ability.

And how fast is the drive running? Use the AJA system test.

Top graph is reading one of the 720 59.94 files from the INTERNAL raid. Bottom is from the XSERVE.
File size is 21gigs. Playback thru FCP with desktop mirror doesn’t work from either location.

Then the speeds are up there. Are you sure you have the setting correct?
This should be working perfectly. I’d try and uninstall and reinstall of the Kona drivers and see if that shakes loose any issues.

It’s been a problem over a year. I’m not sure how many driver iterations I’ve been through in that time period. The problem occurs when I playback a clip in the viewer so not a whole lot of settings to consider.
