So we're producing videos in after effects with the exact same RGB value background as our web design (and developed test site) and when we export the videos and drop them in the background colours are WAY off, any ideas?
you need to change gamma.
you probably are in print sRGB (which has same primaries as Rec709) - but gamma is different.
Change the gamma to 2.4 not 2.2 and things should start to match.
If not let me know. What tools you using? (please dont say adobe! They are horrendous for colour!)
I'm a complete noob but I'd say it is gonna be trial and error.
Maybe do a screen grab of the video background colour and use that value on the website. Reverse the process.
Yeah we are using after effects and illustrator! Where would I change the gamma mugwart? (cheers btw)
I remember something with this problem, you had to open the rendered file in quicktime7 pro and change the Properties of the video channel transparency to blend 100%...something like that, if you are on osx.
but that was years ago, didn't produce video for the webpages with the new versions of AE.
other things I can think of:
check your color profiles in all your files (AI and AE), make the background in AE with exact colors (not imported from AI) and embed the video in the browserpage for check (players might interpret video data differently)
there is also a difference in rendering in AE and Media Encoder...so maybe check the other one also
It's a known issue with gamma and H264 MP4 (Just Google "H264 Gamma Shift"). There really isn't an actual fix (even what uan had mentioned which was what most people did). The solution is to try and counter the gamma by overcompensating in the source so that the exported version looks normal.
You wont get a perfect match btw. The gamma will make things look differently on both screens.
if it was in nuke:
remove gamma (1/2.2)
matrix from sRGB->Rec709(this would be mild if not pointless)
add gamma back on 2.4
render out frames.
convert with ffmpeg
hehe... just screencap the 'off' colors in the video and recolor your svg, pngs etc to match the shitty output (I almost guarantee the client won't notice) ;)
