Hi, I was working on AMD PC and I had many MoviefileIn TOP in my program used as Color mask. When I try to open in NVIDIA PC I couldn’t open file.
Once I bypass everything I could open, but it’s not solving issues. (After I opened file I turned on many nodes and PC was freezing)
Should I turn off “Play” on MoviefileIn in general? What kind of thing I can make data lighter?
Thanks
Hi @kggmmm,
the number of movies able to play on a machine is largely dependent on your hardware setup including drive speed, encoding, etc.
The hang could be due to files not able to open fast enough or reading frames fast enough. The Movie File In TOP has settings on the Tune parameter page that control the behavior for how long the operator should try to open the file before giving up (File Open Timeout in ms) and how long to try to read a frame before giving up (Frame Read Timeout in ms). The defaults here are 10.000.000 ms basically meaning “forever”. Movie File In TOP - TouchDesigner Documentation
Generally though, only the movies currently required should be playing forward. If all their viewers are on, they are being all composited somehow, or all displayed on the output, then that can cause performance issues depending on your hardware setup and movie encoding.
There is a article here on optimization that might be of interest:
