But I have seen the color rotation software in practice and it sometimes works wonders for situations like this.
PE9 does allow one to isolate and apply corrections to different parts of the picture. I gave up trying to correct the color and just used cloning to make the best pictures I could come up with, which you can find below.

You can split the picture and work on the half you want to 'fix', then stitch or re-join the two halves for a closer match.

I have cleaned up the join between the two parts, and have also tweaked both the left and right side, and ended up with this. Whether this what a purist would want, I don't know, but a better picture in my opinion.

Ultimately its all shades of grey ....

My attempt to bring the two halves closer together.

Each half was copied and pasted into a separate file and then separately
colour corrected to get the most neutral colours.
Then each half was copied back over the original as a separate layer and
a colour balance adjustment layer was added to each half for final adjustment.
The right half had its midtones adjusted for more green and less blue and
the left half had its midtones adjusted for more red and more blue.
The left half needed a some masking to slightly reduce the effect of the colour
balance adjustment in order to get the fleshtones closer to those of the right half.

The background still has a bit of a colour mismatch but the overall image
is more in balance than was the case in the original.

If anything it's a good starting point before trying anything else

You have a little yellow color cast.

Here is my version:

Most of you are probably familiar with the film "The Seduction of Lyn Carter" although the download of this title is no longer available on VEF.

I have a DVD that I bought (many years ago) of "The Seduction of Lyn Carter". Published by tvxfilms.com and sold through Excalibur.

You are probably familiar with this particular version (I think it was posted as a download on VEF a few years back but that seems to have disappeared.)

The color quality is poor to say the least. It seems to me, although I know very little (just enough to be dangerous) about how films are colored, that the film stock was stored in such a way as to permit sunlight to bleach the red dye out of sections but not all. So as you view the film (from the TVX DVD release) some of the frames are pretty good quality and then many of the frames have a very greenish tint.

I was wondering if you knew of any software that could handle color correction of a film damaged in this way. Some frames are reasonable, but most frames have a severe greenish cast (lack of red?)

IMO, this film was Andrea True's best work. Largely, in part, due to the director Spinelli and to me it's worth "saving."

Fixing degraded video is hard; when you see big time film restoration projects, they've gone through it by hand-- not perhaps frame by frame, but sequence by sequence. You'll have to go through and mark segments by hand, to a considerable degree.

The shops that do this use custom software mostly, but there's some stuff that you can give a try.

In the free/shareware category, there's some impressive stuff, but its still a lot of work. Davinci Resolve Lite, or Red Giant Colorista are both limited versions from pro video tools companies . . .

Of course a few brightening tweaks can do the trick. Sometimes simplest is worth trying before masks and layers, especially as its brightness that's at fault on home magazine scans.

If it were a soundless loop it might be a bit easier. There are packages to correct tint - like the ones mentioned above - in videos but also some better software that can correct the tints in individual frames. You could parse every frame out using one package and then apply corrections to each frame in a batch mode perhaps but then you have the problem of sync'ing the sound back with a regular film.

Yes, I researched the "problem" starting with the links deepsia supplied.

I think it is all way above my skill level, experience and in a word HARD!

I've given up. Probably won't live long enough for the process to become easy.

Thanks to all for cluing me in.

You might give it a try. The tools are free, and its a useful skill. That said, this one might not be the place to start.

I did look at "The Seduction of Lyn Carter" and this would be very hard. It looks like it was originally shot on film, then converted to video by a not-very-capable telecine operator. _If_ someone had the original film, and it was in usable condition, you could go back to that and rescan it, and do much better.

But trying to fix a bad video from dodgy film is really hard. Colors are all over the place, and its not a consistent thing.
