Can these be made to match? at DVinfo.net

I'm editing a dance shoot where 3 cameras were running simultaneously. One camera produced footage much darker than the other 2. I'm working in PPro CS3 and After Effects CS3, trying to get them to match, or least come close.

They were all shot 720 24p on 2 JVC HD 250s, and 1 JVC HD 100. I use cineform as well.

I've played around with brightness and contrast, luma curves, lighting effects, etc. I'm not an expert in color correction, so I thought I'd post these screen shots, and see what people think.

You can try correcting them with 'Levels', but beware of the grain.

Dennis,

I did a quick color edit in Photoshop to get NoBrite2 to more closely match Brite2. It's not perfect, but this may help you get started. Here's NoBrite2 with the following corrections:

Levels: Input White (100), Grey (0.92)
Hue/Saturation: Hue (-7)
Curves (Input/Output): B (64/64, 128/180, 192/192)

You can do similar corrections in PPCS4. Should clean up nicely. Add a noise filter if needed to clean up chroma noise, or bump up the black level by one or two, or both.

You can try levels, as has been suggested, and curves. Try to avoid brightness/contrast if you can and stick with levels/curves. Your biggest issue is going to be grain due to the gain, but do some tests with different settings and view the tests on a TV. That should give you a pretty good idea what your consumers will see.

Try, try, try again. HD has pretty good leeway. But it's always good to try and get your camera people on the same page. Getting it right in the camera saves TONS of post time!! ;)

Thanks,
Matt

EDIT: Oh, and since you have After Effects, you probably have Color Finesse. That thing offers a huge range of options for correcting/modifying your color. Also, if you've 'upgraded' to Prospect HD 4, then you also have First Light, which is turning out to be a wonderful product. It'll allow you to embed color correction profiles as metadata.
