Adjust video quality

Dear developer-community, i am a user, not a developer in a software sense. Maybe video developer to be :slight_smile:
My interest is the possibility to adjust video quality. I hope i did not just overlooked it. I have very limited bandwidth and there would only watch the videos in a low quality. Until now i could only notice that they are being streamed in very high quality. Can that be changed?
Best regards,
Rolf
