Problem processing large video

Cary Knoop · 29th December 2018, 21:02

I am trying to process a 4K video encoded ProRes 4:2:2 HQ.

Even when I try to simply open (commenting out the decimate) nothing seems to happen (no significant disk, CPU or memory activity):

Code:

from vapoursynth import core
import vapoursynth as vs

c = core.ffms2.Source('a:\video.mov')
#c = core.std.SelectEvery(c, cycle=3, offsets=[0,1])
  
c.set_output()

Running: Vapoursynth R45. Windows 10 on a Threadripper 1950X with 64GB of memory, source disk A:\ is an NVME drive.
