Dear Dan,
Thank you for your response. Here are the properties of the file:
I assume this is an HDR file. What’s the most convenient way to make it look close to the original? Should I manually adjust the contrast and colors in Shotcut? Do I need to convert it to BT.709 first, or can I work directly with the original file?
In any case, trying to match the original colors manually can be tricky and tedious for someone who isn’t very familiar with how color and contrast work. Is there a simpler, more foolproof way to do it? QuickTime displays the video correctly. Is there a way to export or convert it from QuickTime with the correct tone mapping and take over the result as a source footage to Shotcut?
