Color Correction Help

jrazz wrote on 10/9/2011, 5:37 PM

I filmed a wedding for a friend of mine (I don't really do weddings anymore) and I thought I would use my GoPro to get a wide shot of the wedding party in addition to 2 of my A1's. I have never tried to use them together so I didn't know what to expect. They only paid for 1 camera and since they are friends I thought I would go ahead and throw in an extra cam plus the gopro to see how it did.

One thing I was not ready for is the shifting white balance of the GoPro. I assumed that the white balance would not change, but I was mistaken... badly. I can understand going outside from inside, flourescent to incandescent. But in a static scene where only people are moving, I wasn't ready for. So, I would like to Color Correct the GoPro footage. I have included below some shots from the GoPro where it tends to drift the most color-wise.

Any help would be appreciated. I do have Boris CC7 as well and attempted to use the Color Match tool but failed at getting proper results.

I have a similar problem with my Contour helmet cam, which can't be locked to a single white balance setting, and tends to shift in and out visibly in consequence.

You can keyframe white balance corrections as you go, but in practice I've found this time-prohibitive and still not very successful, so I just try to live with it (and curse the designers for not giving more control over the cam).

Don't know if there are any other solutions...

Why not give http://www.fbmn-software.com/en/color-match.htmlthis[/link] a shot. I've tested it on a few clips and the results are very very good.

I did give it a go. My trial ran out a few weeks back. I got some weird results. Which, that reminds me, I need to send him some files related to that issue I was experiencing.

Since there is a white screen on the wall, you could correct all clips so that the screen is always white. In addition to Fbmn's products, there is also the free AAV Colorlab.

To use the eyedropper, un-tick the default "6-vector" box, tick the "Adjust" box and select the "Adjust" word to expose the controls. Use the eyedropper to click on what should be neutral colour (white or grey, but not what has been burnt out to white). To reset a correction, click the eyedropper on pure white, such as can be found in the program's window.

fwiw, I ran each of these stills thru the FBmn White Balance FX by keying on the projector screen. Here's the results.

I didn't spend a whole lot of time on this, except that I added a little FBmn Exposure to the 2nd still - just to make a better comparison. It sill didn't match exactly - note the floor is a bad color match with the balance of the stills (maybe fiddle with the CC or Secondary CC?).

I just had a little play with AAV Colorlab and noticed two problems immediately. First, the second image is apparently underexposed relative to the others. If this is not done, the detail in the folds of the bride's dress would be lost. Second, even if the brightness is lifted, it still looks like the bridesmaids have been dipped in carrot juice (colour saturation is greater).

The dynamic range issue in the first point could be tackled using NewBlue Video Essentials II Shadows and Highlights plugin (or better still, Adobe's Shadow/Hightlight effect in After Effects, Premiere Elements, etc.). Vegas already has a saturation effect you can use.

Hi all,

@Jerry: many thanks for having taken the time to post your stills comparing before/after with a combination of White Balance and Exposure.

@J Razz: Feel free to send me some stills so that I can help as much as I can ;-)
It would be too bad that you feel disappointed if I can find settings that fix your issue. I do agree that ColorMatch requires some practice, and am looking forward to gathering tricky real-life cases, to enrich my FAQ page. You have my contact details on www.fbmn-software.com.

Best regards,

Yes,

I will send you some stills (and a sample from the other footage I referenced in another thread about psychodelic colors).

I don't feel disappointed, I just haven't spent much time with your product (and my trial ran out). What I was hoping for was a simple eye-dropper color match and it is a bit more involved than that. Your willingness to help and be involved goes a long way however.

With that being said, I was able to use BCC 7 Color Balance to quickly make the changes I needed.
