Colour Pass a joke?

Post by troppo »

Recently I have been editing a short project to introduce a film festival. The idea was to take a subject with an orange shirt looking at an orange mango in a tree. Everything else needs to be black and white except the shirt and the mango. Sounds easy right? Is it just me or is the Ulead Colour Pass filter totally useless? It would put ugly lines on everything it was passing.
To get the project done I had to edit in Ulead, where I have an efficient workflow, and then export each clip to Premiere Pro to use it's colour pass filter. Annoying.
Has anyone else experienced unacceptable colour pass filter peformance?
Cheers,
Devil

Have never used it, but I did a trial and I see what you mean. Two things I did find: it worked better on an avi, rather than on an mpg, original and it worked better with reverse checked, provided you keep the similarity to <20%. Not a brilliant filter! :(

I think that a better solution would be to use a video matte (or image matte if there is little or no movement.)

...or use the T shirt clip as a "bluescreen" overlay, using the eyedropper to pick up the T shirt colour, and apply it to a black colour clip. Adjust the "similarity" to get the best combination of mango/T shirt vs other contents of the video. Have a white colour clip as the underlying video, and render it out.

If necessary, use video paint to blackout any other areas that have shown through unintentionally, such as faces. If you don't have access to video paint, render out as a BMP image sequence and just use MS Paint.

Use this black and white video as a gray key matte on your original footage, and have a monochrome copy on a lower track showing through.

Wow, thanks for your varied and comprehensive replies. But i think at this stage it's still easier to export the clip to premiere pro and use adobes much better filter.
Thanks anyway!
