P30 Pro "Red Tint" Mystery. Solve it here.

[EricMartinSoCal]

The "red tint" in video shot on the P30 Pro is well documented on here and YouTube. Someone who knows about this type of tech needs to help us solve a mystery! After hours of testing here is my observation:

The "red tint" is clearly present when I view video shot on the P30 Pro on my Windows laptop, Windows desktop PC and my wife's NATIVE video app on her iPhone! Just as described by many reviewers.

BUT

The SAME video on the SAME device (wife's iPhone) when viewed using the YouTube app looks perfect. ALSO, the same video on my P30 Pro, 4K TV and Galaxy S10+ looks great in BOTH the native video app AND the YouTube apps. What the heck is going on?

I think it's a codec issue. I'm also getting different results per device. If you run video through VLC Player on a PC, then on Adobe premiere pro, then da vinci resolve and Windows Media player, it shows different results

It looks outstanding on my 75 Inch 4K TV which should really put it through the paces as far as quality. So is it the phone then? Or the device? I wonder why I've never experienced such dramatic difference on other phones?

You are right I believe. Here is a screen shot off YouTube playing on my laptop. The first was a file moved from the phone and simply saved using Adobe Premiere and the second is uploaded to YouTube directly from the phone. No editing of either video.

Yeah I'm not 100% sure but I believe it is. I've no issue with it because anything that's precious video for me I'll go and edit anyway

Videos with stripped metadata looked fine on all devices/apps I tested whereas there were differences with intact metadata. Following command got rid of at least "Color Representation" (exiftool) tag without re-encoding.

ffmpeg -i in.mp4 -map_metadata -1 -c:v copy -c:a copy out.mp4

I have NO RED TINT on video recorded in H.265 while there is red tint in some video recorded in H.264!
