Timestamped feedback
Pause at the moment you want to flag, leave a comment, and the creator opens it pinned to the same frame. No more "at around 0:14, second hook line" in a Slack thread.
Structured approval states
Submissions move through assigned, submitted, in review, revision requested, and approved. Everyone always knows whose turn it is.
Revision history that survives
Every version of every cut stays attached to the deliverable. You never lose context on why v3 looks the way it does.
