color match in 4 cameras - help

Hello,

I have footage from 4 different video cameras:

- GoPro 7 Black - recorded in protune

- GoPro 8 Black - recorded in protune

- Sony FDR-AX100

- Sony A7 III (reference video)

I have Graide Color Match plugin, but it was able only to match footage from Sony FDR-AX100 and Sony A7III. I am not able to color match GoPro 7 Black and GoPro 8 Black footage. Can you help me how I can do it in Vegas Pro 17? I always have problems with manualy set hue/saturation/gamma/gain etc.
I have big request to you to help me fit the colors between these two 4 video cameras in Vegas Pro 17 Suite.

I would like also to know how you did it, what parametrs and video effect you used to color match. Graide Color Match plugin did not the job and it is not good result in that case, maybe cause the footage is in protune.:((((((((

Pleaseeeeeeeeeeeee help me:

Here are the snapshots:

1) Sony A7 III looks like this:

2) Sony FDR-AX100 looks like this:

3) GoPro 7 Black (protune mode) looks like this:

4) GoPro 8 Black (protune mode) looks like this:

I do really appriecieate your help.

Regards

Marcin

Do not shoot 10 bit Protune. You will be into the next epoch trying to match it.

Do shoot 8 bit AVC, as your other cameras.

Do you mean I should turn off Protune and never use flat format in GoPro Hero 7 and 8 while recording also by Sony A7 III and Sony FDR-AX100 video cameras and record in normal/standard settings in GoPro Hero 7,8 to let it match perfectly in that equipments set?

I have just applied the continous way in Graide Color Match. I have just started rendering. I will watch it tomorrow. I will write to you my opinion of it after watching the whole video. Thank you for your tips. I need to read a whole tutorial for Graide Color Match at last.

You should ecord 8 bit 420 AVC 2.2 gamma in all cameras.

No protune. No flat log gamma. No 10 bit. All the same.

That way they have a chance of being matched.

Musicvid - thank you for your explanation.

How do you know that protune settings and flat profile are 10 bits in GoPro Hero 7,8?

I am not able to find this information even on GoPro Hero 7,8 manuals.

How do you know that my Sony recordings are 8 bits?

How did you check it?
How can I check if my recordings are 10 or 8 bits? Does MediaInfo tell me it?

Sorry, but I am confused:(

Does Gopro color profile (opposite to Flat) is 8 bits in GoPro Hero 7,8?

Thank you in advance for next explanation.

Since you won't understand linear vs. 2.2 gamma yet, you will need to educate yourself about Protune. It is not a consumer format and I don't recommend trying to match it alongside delivery formats. The information is readily available, along with other essential instruction, such as white balance.

In my catv activities I tend to work with other videographers who show up for events with their own cameras and end up having to match the footage and its a challenge. I find what makes it easier is using my main cam to take a white balance reading using a big white card I usually bring and asking the others to set their color temperature to mine... if they can do that. I suppose we could film a few frames of white card and maybe use the Vegas white balance fx... but I have not tried that yet. In post if I find a scene that doesn't match and cut well from one camera to another, the Vegas Color Match fx can often fix that... if there are alternate angles on the same subject, it lets me capture the reference cam's preview, then capture the alternate cam's preview (by temporarily manipulating the track muting) and generate a color corrected output for the alternate cam. Works well at the track level as long as the cams are not in auto-white balance mode. Otherwise it has to be done as a clip-level fx for each cut over. Another additional approach is picking up one of the xrite color swatch boards and filming it on each cam after matching color temp... I did that as an experiment on my last shoot using the business card sized one that came with my monitor calibrator and, tiny as it was, it worked remarkably well though zooming in enough to fill a frame with it took a little doing. I also found that Vegas17 color curves fx has a new calculate button that will derive a color correction curve all on it's own if you point it at a frame filled by the swatch. I did the swatch thing as an experiment, probably not doing it as intended, but I think I'm going to spring for the larger swatch board they sell and maybe watch some of their instructional videos on how best to use it.
