You can add comments directly to a video or audio file to create commentary or ask questions. You can edit or delete your comments if necessary.

You can also reply to a comment that has been posted in the timeline. Currently, replies only support one reply level. You cannot reply to another user's reply.

Note: Users with editing rights can delete any comment at any time.

After you upload a video or audio file, you can edit the details of the media and add tags.

Details include the title and description of the media. Descriptions do not appear anywhere in Arc, but the content in the description is used to locate the media files when users search for them.

Tags help organize the media and also act as search terms to help users find a relevant media.
