ZitatChecking this option, it will scale to [0,255].
Hm, but i GET the same Color-Range like the Source if i use that, like i wrote in former posts, i've checked this many times.
The Histograms of the Source and the Target-Videos are exactly the same (OK, there's always a little loss while encoding, but that's not what i meant).
Let's have another try:
If you have DV-Source and a correct working DV-Codec, you get a Video with the Range of 16-235. That's the same Range, a MPEG2-Video should have, right?
Now feed this Video directly into TMPGEnc. What Option will you Choose? CCIR601 or YCbCr?. Consider: This is an Output-Option, and the Video still is in CCIR601.
If encoding in CCIR601 only clamps the Range, nothing should happen, because there's nothing to clamp in the Source. But watch the resulting Video, i bet, it is lightened.
If encoding in YCbCr is scaling to 0-255, the resulting Video must be darkened, but (on my machine) it isn't - like my MJPEG-Source also.
That's what i discovered, and i can repeat and repeat it, it's always the same Result.
Why i'm not trusting AVIsynth any longer? Because of all of this mess with the Luma-Range.
