Color Correction-anyone know how to do this?
I want to take all the color out of my footage to make it B&W but I would like to leave in 1 specific color depending on the shot. For Example leave color in an actors eyes or hair or even leave the blood red. Any help would be appreciated.
thanks -

Depending on the range of colors, you might be able to achieve this with secondary color-correction. Generally it requires drawing a moving matte around the object to retain color. Avid’s Animatte works well for this if you have the patience. Put a base layer on V1 and make it B&W. Put the same video on V2 and draw the matte around the object to stay in color. Place keyframes and move bezier points as the object moves through the shot to create a traveling matte.

What you are trying to achieve is known as the “Pleasantville Effect,” named after the movie “Pleasantville,” which used this effect heavily. What Oliver has described is sound and good (as always!), but there’s an easier way (to me, anyway)…or at least, another way to do it. Here’s the tutorial:

The method in that tutorial is your best option really.
You can use an Animatte nested in V2 layer to limit the effect to a general area (get the green of the eyes but not the trees by only applying the Chroma key to a smaller area).
Another way you can achieve a similar result is with the Spill Suppressor in a Chroma Key – add a Chroma key to a clip, turn the gain on the primary key to 0. Enable the spill suppressor, select a colour that is OPPOSITE the one you want to keep on the colour wheel, turn gain right up and play with softness settings. This way is less precise.

The keying is a good suggestion as long as the colors are in a similar range. The advantage to Animatte is that if your requirements expand, you are covered. For example, if one person in a shot should be in color in an otherwise B&W scene, which is actually the correct “Pleasantville” effect.

If you have access to a Symphony with the secondary color correction system, you can do this in the color corrector without drawing any mattes. This is one of the effects that Avid demoed when they added the secondary color corrector.

Thats the problem with ‘Demo’s’ they are never real world examples – I can’t remember ever using the Symphony secondaries without having to draw a matte as well to hold out parts of the image. Eg BW shot wanted except for the actors blue eyes in closeup – but there is a blue truck in the BG too….

Indeed. Although the Animatte plugin can be pretty hard to work with.
If it got to that stages I would be moving the shots to something like After Effects or Combustion to do them. Animatte just become a bit nightmarish with lots of points and keyframes.

Any advice on converting footage to just B&W with maybe a blue or yellow tint?
Would you guys recommend doing C.C. in a program like Digital Fusion or After Effects?
