I am rendering an after effects project consisting of over 320,000 source frames of 4000x4000 resolution, outputting over 250,000 frames as PNG files.
Rendering is instant on our machines, all time is spent "compressing and writing" frames. It is taking forever.
We have several machines that are all windows 7, with 16 physical cores, 64GB ram, connected to a 4Gbit SAN.
I did some experimenting, tried using all 16 cores, or 8 cores, or disabled multi-frame rendering even. When this project is rendering my cpu usage is almost non existent,. maybe 1%-5% at times.
with 16 frames at a time being rendered it is averaging between 1 and 7 seconds per frame depending on the content of the frame.
Does Adobe have any plans to multi-thread the PNG exporter? or is there a faster 3rd party plugin out there i could use? It is very slow and doesn't tax the CPU's at all. Even on a single core it doesnt even use 100% cpu while its saving.
I even tried loading one of the frames into photoshop and simpy hit save as a PNG and it took almost 15 seconds to compress and save. I did it again without compression and it saved the 40MB raw file instantly.
That is terrible performance for machines like mine that are pretty much the fastest things out there.
Thanks!
