Converting Vimeo Files to MP4 on Mac with Correct Gamma and Color Space

As a video editor, I've faced numerous challenges when trying to upload my files to Vimeo from my Mac computer. The issue has been a long-standing one, without a clear solution until recently. In this article, I'll share the simple trick that worked for me and resolved the problem of inconsistent gamma and color space between different video players.

The key to resolving this issue lies in setting the output color space and gamma correctly in the export settings. Specifically, you need to set the project to Rec.709-A gamma (not just Rec.709) in the Color Management panel. This ensures that your file is exported with the correct 1.96 gamma based grading.

I tried various methods before finding this solution, including using Color Space Transform and modifying tags, but none of these worked. It wasn't until I stumbled upon setting the project to Rec.709-A gamma that my Vimeo files started looking identical across different video players, including Davinci viewer, Quicktime, and Vimeo itself.

For those who are not familiar with color grading and gamma settings, it's worth noting that you can grade your footage in the Rec.709-A gamma space and also include this tag in the delivery page for optimal results.

In conclusion, setting the project to Rec.709-A gamma is a simple yet crucial step when exporting files for Vimeo upload from your Mac computer. By following these steps, you'll be able to ensure that your files have the correct gamma and color space, resulting in consistent playback across different platforms.
