  • What is your operating system?

Window 10

  • What is your Shotcut version (see Help > About Shotcut)?

start from 26.25?probably

  • Can you repeat the problem? If so, what are the steps?

Video color changed to red while export:

I don’t remember exactly it starts from what version, probably 26.6.25(I roll back to use that version’s subtitle function), “the video I export colors turn more red and bright” than I saw in the software preview. I tested 26.8.1-26.6.25, they all appear the same issue. I thought it was because the “process method“ is wrong (I was using 10bit and 4k on a 1920 video, only keeping same frame rate). Then I fix it back to original way (I used 10bit and 4k before and it was fine ). But the video is still red and brighter when exported. Then I go to use kdenlive to edit the same video using same method, and this time the video color is correct. So I don’t exactly know what cause the issue, just saw there isn’t any post about the problem I encountered. Sorry for the inconvenience. Thanks for your work.

The subtitle bug is the same as other post .

The color change is really obvious, even I roll back to use 26.4.30.

After editing then export:

both are screenshots from vlc, because I noticed (after I upload to media platform) mpc will adjust the color to look like the original one.

okay, I was using 26.4.30, fixed the problem by using the ‘video mode preset that on the list’ instead of using ‘custom presets’ that I selected which are the same settings as ‘video mode preset’.
