This looks fine

But then when it plays it looks like this:

Hi Rob,
Thanks for your patience. I just heard back from our lead transcode engineer about this issue.
Unfortunately, the reduction in gamma on Vimeo is expected for this type of source file. Despite have a color space of bt2020, your input has a 8 bit of color depth; therefore our transcoder is defaulting to a limited color range. This is resulting in the drop in color you've experienced. At this time, our system can only produce full color range playback files for 10 bit source files.
He also noted that your color properties are tagged incorrectly (possibly by your editing software). Other players (such as Quicktime) are likely ignoring the tags and playing back your video as expected. The only solution here would be to correctly tag the file, and possibly use a bit depth of 10, if you'd prefer to use the bt2020 color space going forward.
I apologize that we were unable to resolve this issue for you, but If you have any questions, please don't hesitate to ask. Thank you.
Sincerely,
Dana C.

Hi Rob,
Thanks for getting in touch, and my apologies for the trouble here. My name is Dana, and I'm the Video Support Manager here at Vimeo.
The color variation you've encountered seems to be deriving our transcoder. It seems to be having an issue accurately reproducing your video's color space (Rec2020) and bit depth (8). I've opened a ticket with our engineering team for further investigation, and I'll be sure to provide an update as soon as I hear back. In the meantime, I would recommend trying to upload a 10-bit video using the Rec2020 color space, if possible.
In regards to the horizontal lines issue, it sounds like you might be running into a decoding issue in your browser. I've performed some tests, and concluded that our encoded files play correctly in other players. For background, each browser (Safari, Chrome, Internet Explorer, etc.) uses a different technology to decode videos. As a result, videos may look or sound different from browser to browser (the frequency also depends on your hardware and CPU) Unfortunately, this is unrelated to Vimeo, but if continue to run into that issue, please take note of the browser you are using at the moment— there may be a bug in Chrome or Safari that is causing those lines to appear. If that's the case, we'd be happy to file a ticket with Google or Apple to address the issue.
Thanks again for sending over this report. I'll keep you posted on any updates I receive from our engineering team regarding the color variation issue.
Sincerely,
Dana C.[/font][/font][/font]
