Old VHS. Colors seems too bright

[cd090580]

Hi,

A friend gave me an old VHS tape to backup it to a DVD.

The video was shooted on an old VHS-C camcorder in 1994. Then the small tapes from the camcorder were copied to a standard VHS tape (VCR to VCR).

No I'd try to copy the VHS to a dvd-r with a standalone DVD recorder. The picture is quite good but the colors seems too bright or washed at some places.

Here is a sample:


Is there any avisynth or virtualdub filters that can improve the picture quality without spending a lot of hours just to see that the final result is the same as the source ?

Thanks.

No ideas ????

What's the reason for the vhs-c to standard vhs? Thats just another generation loss in quality. Don't see why you couldn't burn to your standalone DVD recorder straight from the vhs-c with the full size vhs adaptor of course

Simply because my friend doesn't have the original VHS-c anymore. He only have the standard vhs tape

What is the brand and model of recorder you are using?

The recorder is a Philips DVDR70. All my other copies are perfect. When I play the VHS on the TV the result is the same as on the dvd.

The main problem is the source.
Is there any filters (avisynth or virtualdub) that can improve the quality ?

If I understand you correctly, this tape when recorded to dvd is a bit bright and washed out. This may be due to IRE from the tape being off. The IRE level determines what the recorder will consider to be a black level. For example, VHS sources have IRE black = 7.5 but some recorders allow IRE = 0 for black. If you record with an IRE=7.5 source to a recorder set for IRE=0, the video will appear a bit bright and washed out because the source can only get down to an IRE of 7.5 which is not black to the recorder but a dark gray.

It looks like the Philips recorder can accommodate either. Which way do you have it set?

That looks fairly typical for VHS camcorder although strangely cropped (wide blanking). Consumer camcorders record "bright" to make signal to noise and low light appear better than they are.



This is a simple -5% luminance level correction. More could be done.

Ok I will try that with a virtualdub or avisynth filter.

Is there any way to fix also the blue effect between the sky and the mountains ?
Thanks

I can't tell what that is. It might be Y/C delay offset. It would be easier to tell from a sample with a vertical color transition. It may have been caused during the VCR to VCR dub. See if it's on the original.

It's on the VHS tape. I don't have the original VHS-C tapes from the camcorder. My friend only gave me a copy from the original tapes. He doesn't have the original VHS-C tapes anymore
