Color Correction
I have a problem with some footage I got from an outside vendor. It appears that the video has no blue channel. The color bars at the beginning of the tape are (from left to right) white, light-pink, bright aqua, darker-aqua, hot pink, reddish-hot-pink, dark forest green.
If I take my blue levels and push them all the way up, everything has a blue tint to it, but you can tell the colors look like what they’re supposed to be.
How can I correct this? I have AE7 and final cut pro/color

sounds like they had a bad component connection somewhere.
I would actually demand they give you proper footage.

You probably can’t correct it. The information is missing. You might have to tell them to re-dub the tape, this time taking care to ensure all three cables are connected properly 🙂

If it were only a dub… I think the problem was actually in their camera. The tape out of their camera and into my hands. Our studio wiring is fine.
Assuming there is no way of getting any better footage, does anyone know a way to correct this?
p.s. it looks like this:

Sounds like the 2 strip Technicolor from the 1920s. Odds are that these guys need to get their camera serviced because one CCD isn’t working.

…From the grasping at straws department
Here is a free plugin that may be useful for your problem…. its called 1z1 YUV Tool….
Here is the description from the website…
YUVtool (FREE)
W H Y | once while shooting a feature film, the digibeta cam used then suddenly freaked out and – for some reason – the crew had no chance to repair or exchange it within the day. so I finally got the tape to have a look if the material could be used. Somebody gave me a hint that something with encoding inside the cam was broken/misaligned. so this filter was born, created to manipulate numerous YUV parameters which would not be adjustable by usual color correction. another use of this filter could be to repair a copy of a tape where the YUV cables were plugged in wrongly (called super fast copy mode). the last time I used this filter was with material shot with an HDV camera which was edited in DV down-converted inside the camera. when I got the final cut (on DV tape) for color correction I noticed that on some shots the color channels were offset from the luma channel. I had no time to figure out where these offsets came from, but this filter helped me to fix them.
H O W | the labels of the sliders should be telling enough to know what to do; some technical knowledge about video processing will help, though.Sorry…never used it and dont have a screwed up recording to test it for you…but its free to download and mess with …
Good luck

interesting John
in Shake
you can do a replicate channel
lay in a copy of the Y channel
Gaussian blur – somewhere between 10-20 px
invert or not (the new channel) depending on what you need to compensate for in the color palette.and tweak lots and lots of tweaking.
