I have a Fraps video with full RGB colorspace and want to export tons of frames from it through Avisynth script. The speed is just so slow (about 0.8 fps) with PointResize. Spline36 gives about 3 fps. If I don't do any resize, then I can get about 9-10 fps. I'm using FFVideosource as video opener.
Slow performance happens also in other videos like H.264. This is normal for image sequence export?
Virtualdub status tab gives these during exporting:
Video buffer 31/32
Video frame requests 0
I/O thread activity 0-1%
Processing thread activity 100%
EDIT:
Tried to export frames as JPG and got about 50 fps but with PNG it is that 0.8 fps
Marked quick compress for PNG and now I get about 17 fps. I/O activity is about 10-11%
