Active-speaker tracking
Follow the conversation as speakers change. Keep the person delivering the line in focus.
Follows whoever speaks.
Stacks the cameras.
On a five-person stage, StarZero punches in on whoever talks and cuts clean to the next. Three cameras in one frame become three rows. With no face or voice to go on, it follows the motion, down to a rider a few pixels tall.
Every shot, its own answer.
Podcasts, stages and action.
Crop, follow or stack. StarZero decides shot by shot, from who is speaking, how many cameras there are and what is on screen. Each frame below is composed live in your browser from our reframe API's real answer.

Where to look, when to move.
And when to stay still.
A portrait frame is a sequence of composition decisions. Different footage needs different direction.
Subject focus
Direct attention to a particular person, product, or action using focus hints.
Stable holds
Let the camera settle when the subject is still, so the frame does not keep drifting.
Smooth transitions
Follow movement and changes of attention with controlled camera transitions.
Split-screen composition
Turn tiled or composite shots into separate participant panels when the conversation benefits from both people being visible.
Editable keyframes
Refine the result with smooth transitions, linear moves, or holds. Keep the final choice of focus and movement.
Direct it in chat.
Or build it into your product.
Use reframing while producing a clip or campaign in StarZero, then refine it on the timeline. Keep it in the same project as the cut, captions, and sound.
For integrations, the REST API supports segment and timeline reframing, with access on request. Over MCP, the agent and the Podcast Clipper reframe as part of the edits and clips they make, and recurring workflows can include it as part of a larger production.

What footage should we use for a demo?
Bring examples with speaker changes, moving subjects, quiet holds, or composite layouts. These are the situations that challenge your current process. Compare source and output over the full sequence.
Can we correct the automatic framing?
Yes. Change the focus direction and adjust the keyframes in the editor. The aim is a composition your team can inspect and refine.
Can we use reframing without adopting the whole editor?
Yes. Discuss the REST API or MCP path for your workflow, including source access, aspect ratios, expected volume, and delivery requirements.
