Looking at both pictures I'm wondering which one is using the "correct tint"? Before the screenshots no one commented anything about biased tinting only when we do a side-by-side comparison we notice it.
I can do some experimentation using different codecs but that will take more time as it is. It would be much easier if someone from somewhere can post a direct still capture from the master. And decide once and for all what is the intended "tint".
Dunno what the answer is. Back when I made that conversion filter most peoples displays, if calibrated, were probably set up such that something like the DVD version of Video Essentials looked correct. But this would mean that, if not correctect, PC playback of ATSC HDTV would be a bit off.
Likewise your examples. If you take a supposedly BT709 screen cap and make an RGB jpeg out of it with no conversion then anybody set up for proper DVD BT601 color viewing may think the color is off by a bit. But that would be their problem, not yours, and I wouldn't start mass converting these images because of it.
I don't know what the proper answer is. People view video on many different setups but most everybody sees your web images on their PC's, however adjusted. I just suggested the color space issue in case some movies were improperly in BT.609 which you might find by trying my filter or other conversion on them. This would be especially true and interesting when the BD and HD DVD versions appear to be colored differently for some reason.
And of course we also get into the religious 'directors intent' debate. The Matrix will still be green no matter how you view it.
edit: One other interesting test is to see if converting the video to BT601 makes it look more like the DVD coloring on whatever particular display setup you are using. It should (unless the conversion is already being done somewhere in you decoder chain).
