I like to get some advice on how to write a script in avisynth, that fix the color only to specific frames of the video, and by using some virtualdub filter to fix that color. Is it possible ?
Let say that I want to fix the color from the frame 22000 to 25000, and not touch the rest, how do I do that ?
I know how to fix the colors, I have the numbers for those virtualdub filter So I dont need advise on the filters nor the numbers, but just how to use the virtualdub filter to fix color from one specific frame to an other.
These are the plugins I'd like to use in my script
#To be applyied only to a certain numbers of frame (ex:frame 22000 to 25000)
LoadVirtualDubPlugin("C:\Users\Virtualdub\Plugins\ ColorMill.vdf", "ColorMill")
ColorMill(25954, 25187, 25954, 24412, 25697, 23650, 25956, 24420, 25956, 25188, 25697, 25700, 25700, 1129, 8197)
LoadVirtualDubPlugin("C:\Users\Virtualdub\Plugins\ COLOREQU.VDF", "CEQ")
CEQ(256, 256, 256, 0, 0, 0)
#continuing normal process
TemporalDegrain(degrain=3, ov=4, blksize=16)
Thank you for your time, it is really appreciated

Without a sample, it's quite hard to "imagine" a way to help you out, there are hundreds of colors issues we can think of.
Send a screenshot, a few seconds video...
I know how to fix the colors, I have the numbers for those virtualdub plugins. What I want is to apply those filter to a specific numbers of frame. Ex from the frame 22000 to 25000, I want those filter to be apply, but not the rest of the video. So basically I like to know what to write in my script to make those filter work from one frame to an other, exclusively.
# assuming last part1 = Trim(0,21999) part2 = Trim(22000,25000).FixColor() part3 = Trim(25001,0) part1++part2++part3
# assuming last fixed = Fixcolor() ReplaceFramesSimple(last, fixed, Mappings="[22000 25000]")
Good thank you Jagabo!
Just a quick question, because I am confuse where I should load the virtualdub filter in all this?
part2 = Trim(22000,25000).LoadVirtualDubPlugin("C:\Users\Virtualdub\Plugins\ COLOREQU.VDF", "CEQ"). CEQ(256, 256, 256, 0, 0, 0) ?
Sorry about that question but I am not use to call virtualdub plugins
My advice is to do this in your NLE. It is much better suited for cutting the video into scenes, and then do your color grading scene-by-scene.
