Latency between outputs

[SvenCRen]

Hello Holger,

We will definitely be doing more and more productions like this and hopefully we'll be able to come up with a solution to it. We were using both the outputs on the same machine running in widescreen mode so it was one large file across both outputs. That would eliminate the idea of a frame sync issue between layers but I find it challenging to figure out where the problem actually resides. I do suspect that it would be latency between the two outputs on the video card but I am also thinking that it could be the inputs to the Spyder.

What we observed was not consistent, sometimes the playback was just fine however the problem did happen on the backup server as well so it was not just isolated to one machine. It would be good to find out a way to test this a bit further but I am not exactly sure how because two monitors side buy side would not be a good reference in this case.

I look forward to your email regarding the other issue that I sent on to you. I have to put my video map together for that one ASAP.

Best wishes,
-scott

I have had the same problem directly off machines as well as through Spyder.

The GPU renders each output separately by the nature of how it works. Dynamics in the rendering of each side would very likely create delay artifacts.
