Request: Limiter - support for RGB formats

[TbtBI]

Is it possible to be added support for RGB formats?

What is the use case for it? There is no luma or chroma in RGB, unless we convert it to YUV by using a color matrix, apply limits, then convert it back.

Merging two clips could go out of range 0.0..1.0 (float processing). Yes, one could do something like Expr("x 0 1 clip") but I was surprised RGB is not supported since VapourSynth Limiter is doing it.

I see, a simple channer clipping is needed then. For the note, VS names their parameters simple as min and max. http://www.vapoursynth.com/doc/functions/limiter.html Avisynth: http://avisynth.nl/index.php/Limiter No luma or chroma is involved there, so probably there can be another variant which takes and RGB clip and "min" and "max". Supporting RGB implies a working "show" parameter as well.

Now when I look again at both avs and vs Limiter - it's obvious that avs function is more or less meant only for YUV format. A limiting function for RGB can come from different than Limiter plugin but if there isn't speed difference compared to Expr("x 0 1 clip"), creating such plugin eventually only for debugging (parameter show) doesn't worth it.
