I will try that suggestions as soon as I can, but it seems like more of a workaround than a permanent solution to me.
The actual stitch isn’t being farmed, just rendered from a single machine. Granted, we have an EditShare, so all of our files are located on an external server which we have extremely fast connections to. Since our workflow is highly dependent on this hardware, it doesn’t really make sense to pull all of the files onto a local machine whenever we need to stitch.
I’m not convinced that this is a network problem, since we don’t have problems with shorter length videos, or with other compressions. It almost seems like AE isn’t properly closing out/signing the render. We can watch each frame render, and we have a 2.5 gig file at the end of it, but we can’t open it. I’ll test your solution and see if it tells me more.
Oh, and btw, thanks for your help. Every time I have a technical issue and start researching answers your face seems to pop up in my search results. Its great to have such helpful people in the community.
