Colour through black & White in Premiere pro

[Paul Gallagher]

Hi,

I have seen montages etc with the footage in black and white with say the brides flowers coming through in full colour, is it possible to do this in Premiere pro and if yes could someone point me in the right direction.

Also in some black and white footage is it possible in premiere pro to put a round white sort of border around the picture, like cloudy effect and if yes how is this done?

Many thanks
Paul

Thanks for that Edward, great job I'll try it out.

P.S. Pro probally has the same filters.....right?

[Edward Troxel]

Don't know. I edit in Vegas where we use the secondary color corrector. Just remembered that tutorial being available.

[Paul Gallagher]

Its a great tutorial but it only lets one colour show through, a bunch of flowers usually has 3-4 different colours. In photoshop I can do this by adding a colout mask, but I don't know if this can be done on a moving video in premiere pro, does anyone else know if this is possible?

The other video I seen with it done on was a mac system.

Thanks again Edward.

Random ideas:

1- Do multiple chroma keys.

2- It may be able to key out not-very-saturated colors. That might almost do it.

3- If it's a static shot, you can just mask out the flowers.

4- If the shot is moving, you could always rotoscope it. It's a little time-consuming but it'd work.
Combustion, After Effects are programs you can use to rotoscope.

Chroma keys,

Can you explain maybe a bit more on how this effect works?

After effects is probably the route to go down but I don't own it.

Moved thread to Premirer forum.

I presume Premiere / After Effects can chroma key any color you want.

So basically what you could do is:
Chroma key out the colors that you want to appear.

You have two layers.
The top layer contains multiple chroma key filters which punches out the colored areas. Add a de-saturation filter to remove color from the top layer. You'll have a black+white layer with 'holes' in it.
De-saturation filter: Use something like color corrector or hue/saturation filter. Or a black and white filter, if there's a filter with such a name.

On the bottom layer you just have the normal video with normal saturation.

Thanks for your help Glenn,
I might consider the after effects route but for this project at the moment I'll just take a few stills from the footage and do the effect in photoshop.
I will consider buying AE at a later date.

The best way to do this effect in premiere is to use multiple clips with different colours "Colour-passed" in each.
I.E. Say you want only the colours pink and green to stay and desaturate the rest to B+W
1) Use colour pass filter picking out pink colour
2) Duplicate clip and add to track above previous clip.
3) now add colour pass to 2nd clip picking out green colour
4) Now use a chroma key on the top clip and pick out a mid-grey colour from the background
I have done this a number of times and it works great.

[Paul Gallagher]

Thanks for that Peter, I'll give it a try, do you have to adjust the opacity or anything else on the top clips?

I still can't get this to work,

I must be doing something wrong.

I give up. Either that or go to mac and use FCP lol.
