RESOLVED: Movie File Out H.264/H.265 simultaneous outputs

Hello,

I am trying to write 4x Movie File Outs simultaneously using the H.264 codec. My first two outputs work, but the second two fail with “Unable to open Video Codec (2).”

Is TouchDesigner 099 limited to only 2x simultaneous outputs with the H.264/5 codecs on GTX cards? How about Quadros?

All other codecs work, but I need H.264 as this is for a permanent install for 3 years, of which I am responsible for the AWS bill. :slight_smile: The final media server will be running dual P4000s, so it’s my hope that Quadro supports this functionality. I can test on my M5000 rig to confirm.

Thanks!

As the H264 and H265 encoders use GPU Hardware encoders, this is the limitation. The limit is still 2 for most of Nvidia’s line.

Ben,
Thank you for the reference data, this is very helpful. Yet another reason to #GoQuadro.
Cheers!
