# Push overlays, dynamic overlays, and overlay scheduling for Cloud Playout

> Push overlays mid-stream, schedule them, and apply dynamic overlays across loop and schedule channels.

Cloud Playout's overlay tooling has grown into a full mid-stream graphics workflow.

* A new "Push overlay" control lets you push an image overlay live to the channel without modifying the schedule.
* Dynamic overlays are now supported on both loop and schedule channels, including dynamic overlays in segmented slots.
* Overlays come with an icon legend in the schedule so it's clear when one is active.
* The push-overlay validation has been tightened: file size limits surface immediately, error messages are specific (PNG vs. video, exceed-size, etc.), and 401s during the push surface as toasts.
* Edit and delete actions are disabled while a channel is going live to avoid race conditions.
