Often my videos that i upload to Youtube turn 'pinkish' when played there. And unfortunately Youtube allows to adjust Yellow-Blue ratio, but doesn't allow one to play with any other colour after upload.
Sometimes i can counteract this 'pinkification' by using the Youtube editor and increasing both brightness and contrast, but since that implies one extra re-encoding step i would like to avoid that if at all possible (also it doesn't always work).
What i have notice is that this happens more often if the video is shot with just slightly insufficient lighting, where the video (as it plays on my computer) appears just a little darker than it should be.
- Is this something that is a common problem or is it just my particular approach to recording that causes that?
- Can i expect better quality if i re-encode video locally by increasing luma? Or maybe by decreasing red in RGB?
I am not adding any extra profiles/filters when viewing videos locally. I have tried two separate players (totem and vlc) and both play all the videos equally well. Dark ones are a little dark, but no pinkish colour is added.
The video is recorded by Panasonic HC-V500 and is directly (without any extra reencoding) uploaded to youtube. Recording mode is 1080/50p (i have also tried 1080/50i). The file format is M2TS. Here is the avprobe output:

My monitor is calibrated just fine and i have no problems playing anything else. In fact, as i've said i have no problem playing these exact videos locally before they get converted by Google (Youtube).
