But if they are some edges of some background building way in the distance with shallow depth of field, probably nobody is going to notice. If they are important areas, maybe something like highlights on actors faces, you probably don't want to blindly clip them. And you can take appropriate further action if required. The benefit of _Al_ 's vapoursynth visualization is it will calculate the %, and also importantly, you can see where the affected pixels are.

And if it's an actual full range recording (black and white level are actually Y=0,Y=255), you need to clamp the levels there too. The usual thing to do there is to clamp highlights into range first. Many consumer camcorders actually record Y 16-255 black to white. The downside is they all tend to blur the picture Basically something to reduce the % if it's high. That's where the other filters and manipulations are used, after the conversion and subsampling, you might want to apply a band filter or pass filter. it really depends on theĬontent and edges and the relationships to each other. If you stop there, by definition that's conservatively 100% legal for r103īut you will almost always get some illegal pixels back when converting to YUV and especially subsampling. If you test a standard colorbars video for the input, you get messed up colors and values again with full in,limited outįor a normal range, standard video file Y16-235, using the full range in and full range out equations, clipping to RGB 16-235 is pretty conservative. So which should I do? Not sure, because I don't know how you arrived at those values, and more importantly not sure what type of source you are starting with In limited range the clip values are 19 and 233. I found that if the output were full range, I had to use those wacky clip values that you saw before. If you wanted those clip values it would look like this Stick with that syntax -vf scale,format and you will reduce the chance of having problems later. To be consistent, I would get rid of that last -pix_fmt and replace with format. Reference black and white are still RGB 16,16,16, 235,235,235 there, 5-246 are only for transient under/overshoots too there)Īnd not ok, because you're using full in, but limited out.
(and R,G,B 16-235 for r103, using studio range RGB. 5-246 is only for transient under/overshoots. That's your reference black, reference white. The target range is supposed to Y 16-235.
