Weird, have to check if my media player behave in the same way. Does the same thing happen on all your video files?

I don't know but I've checked a couple other strong red ones and it doesn't happen with them.

EDIT: I opened the blu-ray in avspmod using a script and there it's smooth. So it's MPC's fault.

I see, glad you found the culprit. I usually use VLC but I will check how reds look on my player when I am able to and report back.

Edit: I checked a few films in MPC and I cannot see this problem with reds, I don't own the blu-ray but I checked the '04 DVD and the blockiness isn't there so I have no idea what's causing it with your player.

A few more slight changes:


(129158 - 129574) changed to:

129146 - 129574

this is a strange one the error actually occur before the scene change. 



(166214 - 167938) changed to:

166214 - 168066


(168300 - 168761) changed to:

168237 - 168761


Hopefully this is all of it, all the main affected areas was already found by msycamore and I really don't think I'm going to find more of them. So it seems all that's needed is the slight adjustment on some of the frame numbers to account for the blue shift.

Great job Red5! Will update the numbers, thank you for helping out! :)

Thank you so much Red5 for finding more.

And msycamore, I saw you updated the first post with my script, but there are some errors, for example:

w=trim(chroma,167939,168299)
x=trim(chroma,168237,168761).ChromaShift(C=2)

Copy-paste the one from my post instead, I've updated it correctly with Red5's latest finds.

It's not necessarily MPC, it might have something to do with the renderer or maybe even your video card driver. Is it the old MPC you're using or MPC-HC?

An example of the issue, here's a conversion using bicubic upsampling (Avisynth's default):

MPEG2Source("VTS_01_1.d2v", cpu=0)
Crop(0, 102, -0, -102)
ConvertToRGB(chromaresample="bicubic")

And here is the same frame with point (i.e. simple doubling of the chroma) upsampling:

MPEG2Source("VTS_01_1.d2v", cpu=0)
Crop(0, 102, -0, -102)
ConvertToRGB(chromaresample="point")

@Moth3r: It's MPC-HC, a very recent version. I guess MPC uses that point version you're showing there. Weird indeed.
