    Can someone help me with Old VHS colour bleed removal?

    katerinac64284570 Level 1

      I am trying to remaster VHS footage from 1992 which has very bad colour bleeding in it. The red has gone crazy. I have tried to fix it by reducing saturation snd changing colour balance and reducing grain and noise but no matter how much the colour changes the red glowing outline remains. I am only new into editing so could do with some advice. Thanks in advance.

          There's no easy way to fix this. This can become pretty advanced. You need to separate the channels and involve color space conversions e.g. using the Channel Combiner effect. The basic drill is like that:

           

          1. Convert the layer to YUV

          2. Separate components using Shift Channels

          3. Duplicate the layer at least 3 times

          4. Set Blending mode to add/ Screen/ Multiply etc.

          5. Apply the corrections

          6. Convert the pre-composed result back to RGB using another channel combiner

           

          Depending on how bad the footage is, of course a gigazillion other steps may be involved like sharpening the luma, deinterlacing,warping corrections using distortion effects so things line up, color corrections.

            Hi,

             

            I have solved the problem:

             

            First do ALL editing as once you duplicate tracks you will have to change BOTH of them!

             

            1) Duplicate Video Track 1 onto Video Track 2:

             

            Shrink Timeline Scale So Whole Length Of Timeline Is Visible

            Left Click and Hold Mouse Button Inside Video Track 1 Just After End of Timeline

            Drag Mouse Left Beyond Start of Timeline and up a bit but Keep Inside Video Track 1

            This makes a selection box and selects Video Track 1 in its entirety, Without Audio!

            Press CTRL C to Copy the Whole Timeline (Video Only)

             

            Move Pointer After end of Video Track 1 (You can't paste directly to Video Track 2)

            Press CTRL V

            Now you have a duplicate of the timeline at the end of the original Video Track 1

            Select This Duplicate as above (Make selection box covering Duplicate Part of Timeline)

            Drag this duplicate to the Start of Video Track 2

             

            2) Make Video Track 1 the Monochrome Track:

            Select First Clip on Video Track 1

            Click "Adjustments", Then "Color", Then "More". Set Saturation to Zero

            Make any Brightness or Contrast corrections that may be needed.

            Right Click on First Clip in Video Track 1 and select "Copy"

            Select Track 1 over Whole Timeline as above using a selection box

            Right Click and select "Paste Effects and Adjustments"

             

            3) Make Video Track 2 the Color Track and Shift the Color as below:

            Select First Clip on Video Track 2. Put play pointer in that clip so you can see the effects.

            Click "Applied Effects"

            Select "Opacity", then set "Blend Mode" to Color using drop down menu

            Make any Saturation corrections that may be needed.

            Select "Motion", then type in Position to correct color shift:

               For standard PAL video you will see 360 (half 720 horizontal pixels) and 288 (half vertical pixels)

               To shift color vertically type in 286 instead of 288.

               To shift color horizontally change the 360 number as required.

            Right Click on First Clip in Video Track 2 and select "Copy"

            Select Track 2 over Whole Timeline as above using a selection box

            Right Click and select "Paste Effects and Adjustments"

             

            You have now corrected any color shift on your whole timeline.
