Machines 'dropping off' the render queue
on Jul 14, 2010 at 7:35:29 pm

Hi guys,


We have Windows 2008 server as our centralized storage. All the render machines have the shared folders mapped correctly with all the permissions set. We are using After Effects CS5. What we are finding is that after a few comps have been rendered in a multi-comp project, some will drop off the render queue. What happens is that the render window list disappears and the watch window pops up and keeps cycling as if it's 'lost' the project is supposed to render. Usually, if we reboot or restart the render engine and go back to the watch folder, it "might" pick up the project and carry on rendering. All the machines are on Windows 7 64-bit.


Any suggestions?


Jason

[jason friedrich] "We have Windows 2008 server as our centralized storage. "

Is this server also running under 64-bit?

Hi Dave,

No, the server is on 32 bit. Here is a response from a contributor on the Adobe after effects forum...

"This is a known state, but not directly AE's fault - one of your machines is not able to access footage items within a specific limit and this effectively also shuts down other machines because they, too, go into this waiting forever state. Ultimately it boils down to too many machines trying to access the same files or directories and clogging up your network. The only way to avoid it is to ramp up your network bandwidth or e.g. instead of working with compound movie clips, work with image sequences.

Mylenium"

We have plenty of bandwidth for all the machines. It's weird because the machines will do a single comp, but, when they switch to a multi-comp and jump to the next render item in the list, some will drop off over time. I'm thinking we might try 'nesting' all the comps into ONE master comp and see what happens. Dunno?

If you're not rendering image sequences, you might give that a shot.

You might not ultimately need image sequences, but they have the virtue of being rendered one at a time. If the render stops for some reason, AE can render missing frames in the sequence later. Image sequences retain 100% image quality.

Furthermore, they're really easy to turn into movies. Put one in a comp, add to the render queue, and AE does the job faster than you-know-what through a goose.
