[QLab] video fades are popping in

[Jen Simmons]

When I "crossfade" between two videos, the incoming video does not  
fade up from 0%, but instead pops on at a low opacity and then fades  
up to full. It's annoying - and very visible (well visible to me).  
I've got everything programmed properly -- it seems to be a  
performance issue.

Even if I set things so that the outgoing video plays at 100%  
constant, and the incoming video fades up from 0% ontop of the  
outgoing video -- it still pops on instead of fading from a true 0%.  
The videos are preloading (or at least they are getting a yellow ball  
signal and telling me they are preloading.)

Specs:
MacBook Pro 15" 2 ghz Intel Core Duo
2 gig RAM
160 gig 5400 rpm harddrive
Radeon X1600 graphics card
QLab is on the laptop harddrive, along with the OS
	
Western Digital external harddrive
1 terabtye
connected via Firewire 400
stripped as one huge drive (RAID 0, I believe - not the RAID for  
extra performance)
All media files and the QLab show file are on this drive.

Ideas? Suggestions? Anyone else solve this??
I've thought about putting a fade up on the front of each source  
file, but that's a pain + locks me into things...

I would have expected a laptop this fast would have had no problem  
fading video.


thanks,
Jen
