8mm and Super 8 films can have lots of color issues when restoring and transferring to the digital domain. I'm at the point in my learning curve where I have discovered that the MSU Old Color Restoration Filter (v 0.9) when used in virtualdubmod can find fairly accurate colors which can then be worked with.
My only problem with this filter is that areas in the original with any luminance become VERY white with a loss of details. Here's an example with credit to themaster1 :

Although I can use Gradation Curves to lessen the luminance in the top range, the details are still lost.
Can anyone offer any help or suggestions ?

I am sure you will get a professional answer on here, but perhaps toying with the gamma (some filter must exist for this) might help you out a bit
PS: thank you for the heads up on the old color filter -

Word of warning -- ColorMill has created interlacing damage on some videos I've used it on. It's very random, I don't know what causes it just yet!

Nope, not YV12.
It was an I-frame only high bitrate MPEG-2 opened with MPEG2.vdplugin in VirtualDub 1.8

I'll need to re-add the MPEG2 and MOD to the system, if that's the case.
What I observed I cannot explain. It was not field order issues, but there was some sort of oddity going on, move clearly viewed during a pan.
What has thrown me, however, is the fact that it was random. Two other projects looked fine, only the one was all fubar.Want my help? Ask here! (not via PM!)

I forgot to mention those screen caps were at 4x enlargement. The red lines are one pixel thick in the originals.
And, as mentioned, you can use AviSynth along with Virtualdub to get around the problem. -
Is there a way this can be repaired? I have a video here that had its interlacing messed up by the aforementioned VirtualDub (MPEG-2 source) YV12>RGB conversion, something cleaned up by Colormill.

What has been done to the video? You opened the MPEG 2 video in VirtualDub -- and then what? Some filtering or conversions might leave the video still fixable. Can you provide a short sample?

Well, I ran the first one through Restream, and it was actually fine after reversing interlace. I'm going to see if I run across anything that Restream won't handle correctly. It's not as bad as your 1.9.2 image above.
The footage is so degraded that it didn't look like a simple reversal, but that may be all that happened.
I'll keep you informed...
Thanks.Want my help? Ask here! (not via PM!)
