Video Playback sync on Multple stages	Can't Post

Hi All,

Got an interesting issue, I've got a setup at the momment where I have a single movie Player playing a 800x600 file, this then splits down to 4 outputs, via a Zoomer actor & scaler to reduce the output to 320x240.

Essentially a single file which is outputing to a 2x2 Video wall,

What I'm finding is Stage 1 lags behind stage 2,3 &4 (which stay perfectly in-sync)

Any idea's / suggestions?

All running of a Brand new Mac Pro 2.8Ghz 8 core, 2GB Ram, 3 x 320GB HHD's, 6 Video Output, ATI Radieon HD 2600XT Cards

Thanks in advance
Andrew

Try pre-loading. Use a scene enter trigger to preload. Hope this helps.

An instant without duration....

Hi,
Thanks, Yea tried that already, Have kinda fixed it by delaying stage 2,3&4 by 2 Frames and it seams to be working.

It stills seams a bit odd, as if any thing I would have thought it would have been the other way round.

Now I just need to get it to play at above 12 FPS!

Please file a bug report on this so that I will remember to take a look at it:
