Y levels outside tv range

[PAL sucks]

What would you do? Clip? When I do a PC to TV it looks obvious that it doesn't need that when viewing REC.601 and as you can see the NTSC version doesn't have illegal levels so did someone screw up processing it further after squashing the levels?

I also read some players don't expand the levels back when converting to analogue. Has anyone seen that and how often do you think it occurs?

I clipped off the borders and resized to NTSC for comparison. Edit: woops I shouldn't have clipped the borders for 720 but without borders the luma is greater in the histogram. Also the PAL dvd borders were nice and legal at 15 or 16 or whatever it is it was above the brown region.

The PAL picture clearly has blow out brights. If it's just that one shot with the blown out sky I wouldn't bother adjusting it. But if it's typical of many shots I bring the peak level down down.

Who cares what "some players" do? You want the levels to be correct. Digital video should have luma levels between 16 and 235. Occasional peaks outside that region are ok but you want the bulk to be within that region.

I'd use the default mode of Histogram(). It's much more useful. I usually prefer it horizontal rather than vertical so I use TurnRight().Histogram().TurnLeft(). Or I use VideoScope() which shows smaller details better.

What about the colors?

Edit: posting my solution for future reference if somebody should hit upon this through search since I have seen other dvds have blown out whites (Exorcist, Creepshow circa 1999 WB dvd).

For whites above legal values try to adjust without reducing contrast, gamma value may need adjusted to taste:

smoothlevels16(input_low=4096,gamma=1.08,input_high=65280,output_low=4096,output_high=60160,chroma=0,lmode=1,dither=-1,smooth=0,limiter=0,ecenter=65280,brightSTR=0,darkstr=200,ecurve=1)

To counter cool color settings use tint.avsi, may need to adjust strength or green level which is the middle two digits:

tint($FF3100,30)

Later last night I thought someone probably adjusted contrast post tv levels. It happens through the whole movie which has a good bit of sky and sunlight through windows.


The colors caused me a lot of grief and after trying to smoothtweak it I settled on tint($FF4100,29) to counter the cold color setting they used. It looks pretty good and I certainly don't want it yellow like Anchor Bay used to do to their releases. Is there a way to subtract that tint command setting it for blue?

The colors look a lot better. And the levels are within the correct range now.
