My comment 1 was a copy/paste error. A test of my MOV files shows no problem, both older and current MOV files from a Nikon Z camera. We need a sample video with which the problem can be reproduced. Maik
The comment 3 makes me suspicious now, I definitely posted the correct text... Another question, since you have provided practically no information, is which digiKam version are you using exactly? Are you using the Qt5 or Qt6 digiKam version? Maik

I noticed some issues with version on 8.4.0 and recently updated to 8.5.0 but the problem remained the same. So I have reverted back to version 8.2.0 yesterday since it doesn't have a problem with Quicktime videos. I will submit a picture of how the colours are displayed later, since I will need to install the newer version again.
Please answer the question whether you have installed the Qt5 or Qt6 version of digiKam? What is the exact name of the installer for digiKam-8.5.0? Or look at the component information in the digiKam Help menu. Maik

We probably need a MOV sample video from you. Do you have an AMD graphics card? Please try to activate the option to fix AMD problems in the digiKam settings under Miscellaneous-> System. Restart digiKam and test whether the problem still exists. Maik

Thanks, I've managed to solve the issue. I went to Miscellaneous-> System and changed decoding settings from ffmpg to WMF (In reply to Maik Qualmann from comment #8) > We probably need a MOV sample video from you. > Do you have an AMD graphics card?

Created attachment 176624 [details] HEVC MOV. file
(In reply to kasiaslopien from comment #11) > Created attachment 176624 [details] > HEVC MOV. file Sorry, the problem is half solved actually, so I had to reopen the case. The HEVC Quicktime videos (taken with Iphone) seem to be problematic. I have changed the settings to WMF and the video plays OK, but if I want to fast forward "an error has occured" pops up. And so I am unable to skip back or forth in the video. If I reset the setting to ffmpg I can fast forward but the picture is distorted. I've updated a sample above. Would appreciate your help.
Sorry, but we can't do anything with a video filmed from the desktop, it's absolutely useless. We need the original video that causes the problem. With digiKam-8.6.0 there is the option to turn off hardware video acceleration and texture conversion. If you have tested these options and there are still incorrect colors, reopen the bug report with an original sample video. Maik
Sorry, I can't find a video that I would be able to upload without having to trim it, which then changes video's parameters. The problem lies in the colour mode of the video. In Digikam it is listed as Other. It seems that other Mov videos with same hevc codecs but with a specified CCIR-709 are displaying well. Sorry if that's not helpful..
I can't find a sample video with an unknown color space. MOV video files can be "hard" cut, so just copy a few MB from the beginning of the video into a new file and make that available. Maik

My OS is Windows by the way. If I want to edit a video I need to use Windows Movie Maker or other programme. Can you edit it in DigiKam?
