Question

With the Color Range keyer selecting colour has stopped working for some footage

In AE CC 2017, I have a composition (A) where the footage is from another composition (B) and this composition (A) had 11 colour range keys on it. And they had worked at one point and I had selected the colour to key. Now, when I add a color range key to the composition, pressing the icon to select the colour to key switches to the (eyedropper?) icon but when I place it over the footage to select the colour it changes back to the normal mouse pointer so doesn't select the colour.

The video that's started having a problem is quicktime pro-res - even though colour range key worked okay on it previously (note: I'm using Windows 10).

I've also tried using the footage from composition (B) in a new composition but that does the same thing (just shows mouse cursor over the footage). But if I put a color range effect on a video rendered with quicktime jpeg2000 it works as normal (shows the eye dropper when cursor is placed over the footage).

I've tried loading the pro-res video into a brand new (empty) project and the color range keyer works as normal there (shows the correct icon when placed over the footage).

Is there a quick/simple way of fixing it in AE CC 2017 (there's an issue with the project when you load it into AE CC 2018 too, and that doesn't load a quicktime jpeg2000 compressed file and I doubt it will render to it either) so in the main project the color picker works properly with the pro-res video like it had done when I added the previous color range effects?

Note: I've tried turning hardware acceleration off in "general->display" but that didn't make it work again with the pro-res based comps in the main project.

Is there something within the main project that's become corrupted? Would I have to copy everything out of the project into a new project (and is there a good way to do that)? Or would it be better to re-encode the pro-res file as an uncompressed video and replace the video in the project with the uncompressed one (even though that will create a big file (since it's a 4K video) and that will create a file I shouldn't need if the project still worked with pro-res?

edit: I tried replacing the video in the project with a png compressed version of it and the colour picker still doesn' work in that project for that video.

Sure you can collect all media and create a new project with collect files

Go to File/Dependencies/Collect Files

Thanks a lot. I collected the files (though not the media) and saved that. Though when I open that project (that was the collected files) I still get the same issue with the eye dropper icon changing to the normal mouse pointer when when I click on the color range key effect and move the mouse over the ProRes mov or a composition derived from it (ie. clicking on the eye dropper icon would change it to the eye dropper but then moving the eye dropper to the composition window to select a colour would change it back to an arrow pointer). Though when I select "new project" and put that mov into it (just that) and add the color range effect, the colour picker (eye dropper icon) works normally with it.
