Question: Ok, first things first: [here's a screenshot from a recap I've downloaded](https://i.imgur.com/roBCN82.jpg). I guess if Neil Patrick Harris would host the ceremony back in 70s it'd look like that.

There's this obvious offset of the yellow colors, but since it's all in RGB, I guess that's an offset of the R and G colors combined? And the rest of the picture looks pale as well.

The file was downloaded using WinSCP. It's a large file so I can't redownload it, but I guess if the downloading program had messed things up it wouldn't open anyway. So the issue might be caused by some incorrect settings on my PC? Or is that a fauly video card? Although the rest of the system, as well as other video formats, look fine, but who knows.

I am confident the source file is fine.

Where do I look for the fix? Any ideas are appreciated

Answer: 
Yes, it is unlikely that it is something wrong with the data you have downloaded.

Depending on what video player you use, you can try fiddeling around in the settings in order to get satisfactory colors.

It could be anything from a faulty video card to a bad monitor. However, most video players lets you change color rendering.
Thanks for the input guys, sorry I'm not allowed to upvote right now.

I've managed to narrow it down, you're right, the issue was caused by the renderer settings, I had `EVR Custom Pres. **` selected although I've no idea how did it get there as I didn't choose that option specifically.

Resetting the output settings to use the "System Default" renderer has solved the issue.
