Here is a low-action sequence example of what I mean. Keep in mind that those are three back-to-back frames,
Look at the subs. First frame has them, and third frame doesn't. But the second one still has the luma with subs, but its chroma clearly comes from the third frame, without subs!
And it's even worse in action sequences. I made a clip (Huffy, about 24Mb) to show the problem in all its glory. Watch it frame-by-frame to get a better idea.
I tried various filters for deinterlacing and deblending, always ending up with the same result, so I doubt those processes are the cause. I haven't even bothered cleaning up the footage yet either (apart from cpu=6), because I feel it's useless to try it at this point. That will be a whole new can of worms. I'd rather tackle problems one at a time!
Here is my current script. Pretty bare, but as I said, I haven't really gotten into the cleaning up yet. I stuck with Leakkerneldeint for now, since it's so much faster (though I think Sangnom looks better).
Crop(6, 2, -26, -10)
Is this a known problem with that DVD? Or is it something I might have done in the ripping and indexing process? I haven't done it any differently than usual, but one never knows...
But most importantly, how do I correct that? I know how to correct chroma shift within a frame, but haven't found aything about doing it between frames...
Has anyone else had that problem? Any help will be appreciated.
