Converting B&W to Sepia

Hi folks, I am about to encode a classic, it's in B&W (I guess the technical name would be greyscale). Does anyone can give me a hint on how to convert it to sepia, using an AviSynth filter?

RGBAdjust() ColorYUV() Can't tell you what settings to use but those are probably what you're looking for. When you figure it out, please post your settings.

RE: Converting B&W to Sepia

Hi- I've fooled around tinting old silent films. Here's my method, which has been adapted from other scripts I've found here and there (sh0dan and mf are the inspirations, I think): First make an .avi following some variation of this script: BlankClip(Color=$CC9933) ConvertToYV12() LanczosResize(512,384) Choose whatever RGB values you want. This is a kind of brownish yellow (is that sepia?). Making the .avi takes no time at all, but I've wasted a lot of time trying to get the exact color I want. Then, if the name of the .avi is Color.avi, tint your main movie like so: LoadPlugin("F:\DivX Stuff\GKnot\2.5Plugins\mpeg2dec3.dll") A=Avisource("D:\Chaplin\Color.avi") mpeg2source("D:\Chaplin\Chaplin.d2v") crop(10,0,700,476) LanczosResize(512,384) MergeChroma(A,0.7) Strengthen or weaken the influence of the color by adjusting that 0.7 up or down.

I'm working on some stuff with a guy who is really into old films. I'll ask about true sepia seed color.

Mergechroma is probably the easiest way to control. Coloryuv(off_u=something, off_v=something_else) is probably the fastest way.

RE: Converting B&W to Sepia

Just out of curiosity, I experimented a little trying to get a "good sepia color" the settings I used on an already greyscaled clip was this: Coloryuv(off_u=-22, off_v=25) thought it pretty decent, but one can use this as a starting point to tweak to their own liking, and depending of course on their input clip

Thanks, folks, both solutions work great on preliminary tests I've done. I will post my final settings when I finish. Thanks a lot again.

Ok, this worked for me: ColorYUV(off_u=-32, off_v=32) Thanks again, folks.
