Fixing Red Tint on RE Afterlife

[SquallMX]

After watching my RE Afterlife Blu-ray I noticed a red tint during the whole movie, after confirming this with VDub, I used FFDShow to fix the video and create a proper BD-R, now the movie looks fine, but when adding colormatrix() to my AVS file in order to create a DVD-Video backup, the resulting output has a slight bluish tint that i can not remove with FFDShow. Any idea how I can correct that?, or better yet, doing the initial correction in AVISynth.

what made you hit the red gamma so hard when it looked like a gain issue?

everything will look cyan if you reduce the gamma of the red channel (-.04 is a small number, but a HUGE difference in gamma).

RGBadjust might give you better control over gain, or possibly rgblut (part of masktools v1) will give you a bit more precision and allow you to adjust more than just gain if you need it.

...or leave it reddish... they may just have wanted it that way. credit rolls are made digitally, and there's very few places a tint can be introduced accidentally in an all-digital post workflow. conclusion is that they probably wanted it that way (at the very least you can conclude that they signed off on it. they may not have noticed a red shift as eyes tend to lock onto the average and white-balance themselves after a while).

It was just a quick fix with FFDShow, I never thought too much about it :o.

Thanks for your answer, at first I too concluded that was it was an intentional effect, but after watching the DVD (the one included on the BR+DVD combo package), I noticed that the DVD does not present that red tint (actually the framing is different, and the image is way more darker, almost like if they used a different master source). I just found weird that without Colormatrix() the bluish look was not noticiable.

I will try with the plugins that you mentioned :thanks::thanks::thanks:.

strange that the DVD should be so different.

how old is this film? i didn't think these were that old - it's all about "universal master" these days, but from your description what's happened is they've done a DVD transfer off an internegative or something.

i'd be inclined to trust the HD version more in this case, but it certainly seems weird that it should be tinted like that.

back when i was transferring film, i'd be super-careful to make sure i kept the colours as accurate as possible. the good thing about a modern film scanner (as opposed to a "telecine" which is a very different exotic beast) is everything is calibrated once-off and all one has to do is set the black point and scan the thing, then adjust later as needed. colours don't drift, everything's sharp and there's tons of precision and less grain. on a telecine one has to agonise over whether the LAD patch at the start bears any relation to the actual film, or whether to follow your gut and keep whites white and blacks black (which often trashes the flesh tone unless you actually make blacks greenish).

in your position i'd colour correct the HD version with RGBadjust (note: it's built into avisynth, so no plugin needed). screenshoot it, use photoshop's levels (white point only) and do a bit of maths to get the required 0-1 floating-point gains for RGBadjust.

...watch out for the Nausicaa blu-ray, where Ghibli insist the red cast is intentional as Miyazaki attended the HD transfer. who are we to argue? :)

The movie is new (2010).

but from your description what's happened is they've done a DVD transfer off an internegative or something.

Thats probably the case, oddly enough both transfers have perfectly synchronization and the same length.

Just a small comparison (Top BR, Button DVD):
