When uploading a video to Vimeo the video is transcoded by Vimeo and in the process red gets a bit more saturation and the contrast is increased a little.
As I chose Vimeo as my platform I have to live with that and hence compensate for it during my video production.
How would I determine the exact amount of red desaturation and contrast decrease? Can I overlay the screenshots somehow and calculate a difference? Is there maybe a plug-in for Premiere Pro that compares two videos and outputs a suggested colour correction?
I know I can do this by trial and error, but I'd rather have an automatic solution.
Here's an image showing the effect:
Note the difference of skin tone between Safari
and Vimeo HD file
. The latter is the intended colour.
