More Types of Video Annotations?

Does Label Studio support video annotations with other shapes besides bounding boxes, such as polygon or pixel-wise masks, spatial keypoints, text overlay on a shape (like https://labelstud.io/templates/optical_character_recognition.html for videos)? The "control tags" for these features that work for images don't seem to work for videos.

The original poster in https://github.com/heartexlabs/label-studio/issues/3693#issue-1583979964 mentioned some of these features in their post about timeline segmentation, but no further detail was given more advanced spatial/geometric annotations.

Thanks!
