Since yesterday copyright-holders have to provide timestamps when claiming videos manually. This way you can see exactly which part of the video was claimed.
You already saw that before, but only on automated claims.
Furthermore, you are now able to edit the claimed videos in the Studio-Editor. There are three possibilities:
- Mute audio completely for the claimed part
- Swap the claimed song with one from the YouTube Audio Library
- Cut the claimed part
The affected part is highlighted in the editor, too!
