I'm fairly new to coloring and have been able to amass enough work to get a reel together. My only question is: what is the best method of exporting and which service to use for getting it to potential clients? My DNX 175 out is an extremely large file and Vimeo's conversion + computer monitors crush any sort of nuance my work has. Any suggestion?
3. Compress that ProRes using compressor or similar program (I've been satisfied with compressor, some use handbrake) into H264 using those specs, then bring the resulting h264 into Resolve and compare against the original.
4. If you're happy with the h.264, upload it and it should not recompress (or at least, only to create different resolution and bandwidth versions).
Definitely consider the presentation on the website. There will be a difference in perception of the blacks viewing against a black, gray, or white background. Also, one thing I like about Vimeo is the ability to limit the interface and customize the colors on the embed.
A lot of people are viewing now on devices with adjustable brightness, so if you are worried about crushed blacks, you might want to have some color bars or other reference that you can check displays with.
