WB postproducction and mirrorless camera

Hello,

I have some videos, my first recorded videos. Normally I take photos and somebody told me that I could setup the WB with postproduction.

I thought... well! will be easy like a RAW and the grey point but... WTF. I'm getting crazy.

Any advice?

Thank you

Not sure i fully understand what you're asking, but seems to me that you have shot your video at a fixed WB and would like to put back the reds in post?

This will not yield good results unless you are very shallow. You need to WB manually by WB on a white slate or similar at shooting depth before you shoot your video. Unless you are shooting RAW-video that is with a Canon 5D running "alternative" software.
