Dynamic Overlays: Update Graphics on Live Channels Without Interrupting Playout

CloudPlayout channels now support fully dynamic overlays. Add a new lower-third, reposition a logo, swap an L-band, or remove an Aston while the channel is live on air — all without interrupting the output stream. Previously, overlays had to be configured before a channel went live; now you can mutate overlay state at runtime and see changes applied within seconds.

Add overlays mid-broadcast — Push new overlays onto a running channel and have them appear at the start time you specify. Update overlays live — Change position, source image, or schedule for an overlay that’s currently on air. Remove overlays cleanly — Delete overlays mid-stream with precise cleanup at the configured end time. L-band and Aston variants — Configure dedicated slots for L-band and Aston overlays with independent time windows. Preset reuse across channels — Apply saved overlay presets across multiple channels for faster setup. Predictable layering — Main video, scheduled overlays, and dynamic overlays render in a consistent z-order, so graphics never disappear behind each other. Dynamic overlays are configured through the overlay configuration endpoints on a channel. Your existing scheduled overlays continue to work unchanged — the new dynamic capabilities are available alongside them.
