Thank you very much for the reply!
If you ask me, I would prefer the settings to be saved as a whole. Especially if you have a lot of videos, it's very annoying to have to make the settings you like every time. Many videos, for example, are too bright for me, so that I lower them a bit. This also improves the quality (as well as the contrast). I would very much prefer not to have to adjust this every time.
Thanks a lot!
