Brightness/Contrast Difference from PC to YouTube So I have a trailer I've been working on, I did everything in Davinci Resolve 12. When I convert the video using Handbrake everything looks fine, but when I upload it to YouTube, either there's a ton more contrast, or gray is being remaped to black, not sure, but the photos below should show what I'm talking about.

I've done quite a bit of research, and the closest I've come is there might be something wrong with the way YouTube treats color spaces in conjunction with how I converted it. Any ideas? Thanks.

EDIT: Just finished uploading a version I converted with MPEG Streamclip, and the color looks great, though it was washed out on my PC. It came out as a ~200MB file for just a few seconds at 100% though, so not fun to upload. Looked just as crisp with Handbrake at ~27MB. Any way to take the color/brightness stuff from Streamclip and use it with Handbrake?

YouTube:

VLC on my PC:
Looks like Handbrake is outputting full range but flagging it as video levels, so the Handbrake output actually has Y=0 as black and Y=255 as white but the flag is telling Youtube that Y=16 is black and Y=235 is white.

If you upload a short segment (3-5s) of both your Handbrake input and output, that can be confirmed.
