VHS to dvd, Video the reds are way to red....can it be fixed

[Denvers Dawgs]

I have a dvd that was made from a VHS tape. The reds are way to red and cause a blurring effect on anything that is red. Is it possible to somehow fix the color on the dvd? I no longer have the VHS so all I have to work with is the dvd, and the file on my PC I took back off the dvd. Looking for preferably a free way of doing this if that is possible as well

You can extract the DVD mpeg-2 files out, and use tmpgenc to re-encode to DVD mpeg-2, with the advance manual color adjustment in the tool. Then author the DVD.

You can also use virtualdub's filter's to adjust colour correction's .
Filter's can be "daisy chained" if needed , though encoding will take longer .
Preview alway's available .

From vdub , it's frameserve to bbmpeg and encode to mpeg2 (various tweak's as well)

It's a free method .

If the colour bleed is recoreded in the DVD then colour correction on it's own might not be enough.

Possible to post a frame?

Here's a few captures




hmmm, they don't seem so bad now. Maybe it was just the tv or dvd player that caused it. I'll have to try my other tv adn dvd player.

Also, could tmpgenc's Trial version allow me to fix the color?

The tv did it. I have an old tv that does that. Turn down the saturation, it'll go away.

quick adjustment right half (Vegas)
-20% saturation
+20% unsharp mask (0.15 radius, 0.15 theshold)

The reds above are still pretty noisy. Lotta noise everywhere, in fact (look at the boy's exposed arm and elbow, and flesh shadow areas). I've read that the red (lower) color spectrum during recording is most affected by (a) poor or inappropriate cables. My Monster cables used to produce this red problem, as well as murky cyan gunk in shadows. The problem went away when I threw out my Monster stuff. (b) Some VHS tape brands had nosie in this area. Sony VHS tapes of every quality had this irritating defect, as well as the low-grade tapes from other brands. (c) Low voltage in your system -- too many components on the same circuit -- definitely produces this problem, though it's usually also accompanied by severe color bleeding. I don't see too much of it in this capture, so I'm going to conjecture it was caused by either the cables, the tape, or both.

Vdub and Avisynth can take some deblocking filters that might help. They're tricky to set up, but might be helpful. You're limited to methods you can use, because your "master" is already MPEG, but maybe someone here can offer more tips on a fix.

It is just normal VHS recording (with oversaturated chroma), not a cable or tape brand problem.

Yes, edDV, I'd say it happens a lot, especially at slow VHS speeds. Or with an underpowered input signal. However, it was REALLY bad with my Monster stuff, especially their Series 3 S-Video wire. Yes, a lot of it went away with better cables. No, not all of it. But a lot. As with everything VHS, your mileage may vary .
