I noticed my Kdenlive-exported video looks slightly more reddish after uploading it on Vimeo. It's not too pronounced but enough to make the skin tones look a little off.
I exported my video the default ITU-R 709 color space which, as far as I understand Wikipedia is the exact same as BT.709 which is recommended on the Vimeo help page so I don't know what went wrong, but mostly I don't know what between Vimeo, KdenLive or my possible bad use of either is responsible for it.
I tried both with webm and mp4.
Any ideas?
