BTW I'm using an nvidia GTX 275, driver 260.99. I delayed updating the driver because of some other premiere issues that it caused.
Computer is an i7920 with 12gb of ram, SSD boot and WD raptor. Footage is AVCHD 720.
Just for argument's sake, what happens when you eliminate the time remapping on your background (Video 6) layer?
Well I just ditched those 2 layers and started with fresh clips with no effects or time remapping or anything. set layer 7 to multiply and applied the track matte to it and got the same result.
On the same timeline video 1,2,3,4 are 4 layers that do the same thing. If I replace with the nested clip from video 7, then it works. But get this. If I copy those clips to say video 5,6,7,8. Then THOSE clips stop working too.
is there are issue with having 2 track mattes on the same timeline?
If i copy layer 2-4 (2 video track s and matte) to layers 5-7 and then set the track matte to layer 7 it'll flake out. Just out of curiosity and then dleted the original tracks (1-4) and copied the flaky ones back to the bottoms of the stack. Set track matte to 3 and it all works.
I then moved the track matte layer to layer 6 and it flaked out again.
So it seems that putting the track matte in layer 6 or above with make it fail.
I've tried this in a few different ways now it fails reliably in layer 6 or above. So is this just me, or is it a bug?
