    That's not fixable. There's no red and blue information in the image. The best you do is make it back and white.

    what Tom says - just green, red and blue chanel are empty ...

     

    Consider to make it b/w, crank up a bit contrasts, maybe sharpen a lil':

    old pictures = black&white, that's a perception habit .. better than green&white

    ok so how do i remove the pixelation now? After I did the color correction its now pixelated. It was so dark so I brightened the video. How can I fix this? If you look at the benches you will see what I mean.

    You can't. The video is very poor quality, and it's not helped that it appears to be scaled up. What is the resolution of the original media? The output file is 1920x1080, which I'm sure is not the size this was shot in.

    It was converted from a VHS tape to a DVD. So I converted the DVD. Should I put it to 720x480?

    That would help, but the VHS quality is very poor to start.

    that is a very very low quaility source.. recorded in low-light conditions, analogue, probably several times converted...

     

    Plus, we are used to fullHD in its shiny glory, have a look:

    res vhs.jpg

     

    The cyan box is an actual TV; the orange box is the theoretically max. resolution of DVD (=never in real life); and the tiny blue square is the real-life res of  analogue VHS. (a Retina-iMac is 6x the cyan one,...)


    Now what happens when you blow up your homerecording by that factor?

    Not meant offensive, but don't believe C.S.I. Miami etc

     

    No process whatsover can re-enact detail what's not on tape.

     

    What I would consider, is, to make the video SMALLER. That tricks the eye, the pic looks sharper, has more contrast than a blown-up version.

     

    What is your final delivery? Where or how is it watched?

    Thanks so much for your response. So I am putting it back to 720x480. Do you think that will do by tricking the eye?

    If it's playbacked on a fullHD monitor? for sure No

     

    Again: what is your final delivery, or to be precise: on what kind of display will it be watched?

    Whatever source you playback on a telly, it usually & automatically gets 'zoomed'/blewn up.

     

    Therefor my suggestion: make it smaller, add black bars around it, so the real content doesn't get multiplied by 8 but by 4 or wotever....

    Its going to be played back on a flat screen TV. How much smaller should I do it? I did it to 720x480 and looked awful! Way worse than in does on the mac. What size should I make it?

    If this is an HD screen, you will never make this look good. If you handle the media correctly standard definition size scaled on your TV should look better than scaling in software. The original media was terrible quality to start, probably multiple analog dubs old before it was compressed for DVD, and then ripped from the DVD back to a production format. To improve it you might need to consider your whole process from the original media you have. What do you have? The VHS? The DVD? How are you ripping it?

    I have both. I used handbrake to convert the DVD. The quality looks the same on the DVD as the VHS and maybe even better.
