Bug: Colour shift when video exported from Express

[Ru Howe, Stornaway.io]

Hi,

Exporting a video with a colour background to use against a same colour background on our website, the background colour in the video changes on export.

We've found this via our Express Embed so I am reporting it here.

Background colour of images does not change on export.

Specifically: 

I set the background colour of the Adobe document to FFCF03

I export it as video and the background colour in the exported video comes out as FDD506

See attached screenshot - the video is lighter, less saturated.

The workaround for us to to edit our images and background colours to use the same colour as the video, rather than the other way round. Ideally that shouldn't be the case, of course - it should match the RGB colour we specified.

And I understand the difficulties in colour profiles with video - but if possible, it would be great for the team to do some work on trying for greater colour matching on export.

Thanks,

Ru Howe

I see only 2 eyeballs on this after 3 days - could you let me know if you've been able to pass it on, or where else I should post this?

Hi there,

thanks for reporting this—I agree with you that an ICC profile mismatch is the most likely cause.
Can I ask you whether the same happens on Adobe Express? I would be very surprised if it's not the case.
I'll raise it internally and let you know what I find out.
Thanks for your patience

Thanks Barranca! (Should I call you Barranca or Davide?!)
Yes, my colleague checked and it's the same in main Express.

Hi Ru,

Davide, my name, is perfectly fine 🙂 
I thought that, thanks for confirming it. My suspicion is that the input image is treated (assigned) a different color profile (or the profile is discarded and the default one assigned), and in the video creation pipeline, this wrong profile is used in the conversion to whatever ICC it is used by default in video production, hence the discrepancy when you go measuring the two HEX values. But I might be wrong, reason why I've asked to engineering.
If the input image you use as a background is not sRGB, I would give converting it to sRGB first a try.

Thanks!
Helpfully for debugging, in this case, there's no input image being imported into Express with a colour profile - it's a background colour set with the Express background colour picker, set to that specific Hex. 
And when you export it out as an image, it keeps the exact hex / rgb colour.
But when exported as a video, a different colour profile is applied and it shifts.
In the old days, this used to happen with Quicktimes because of gamma.
But this feels like the Express video export is using a profile that's different from what the image exporter is using.

Engineering is looking at this, and yes, ICC profile conversion is very likely the culprit here.
Thanks again for bringing this to our attention.

Somebody noticed this colour shift again today when exporting something that they wanted to match to their website background coloir.
