I would like to annotate a bounding box for a video,
but when I try to specify it in JSON, it doesn't work.
Is there any way to do this? Or do I need to implement it?

Thank you.

Creating bounding boxes, points, polygons, etc is only possible in images for now.

For video, there is only event (timestamp) annotation at the moment.

I will add information about JSON template schema and annotation possibilities in the wiki.

I'm sorry for the late reply.
Thank you for the detailed wiki.
It was very helpful in understanding the specifications.

Also, are there any plans to implement a new type of Annotation Object?
If there are any future features, I would appreciate it if you could let me know.

We add new annotation types and functionality when we have new requirements, but we don't have a new features roadmap at the moment.

About new planned functionality, we just merged into main branch a beta version of a new type of annotation for use with multiple images at different angles of the same scene, using epipolar lines. I will add the documentation to the wiki soon.
Also we have planned some improvements for reviewing results from a model.

About bounding boxes and other annotations directly in video, there is no plan at the moment. Some users handle video annotation by annotating video frames as images, but I understand in some cases is not practical.
