FUSION WORKFLOW / 08
Level: Beginner workflowAutomatically Keep a Presenter Centered in Vertical Video
Tracker with IntelliTrack follows the presenter, then Transform scales and offsets the source so the subject stays inside the target area of a vertical frame.
Understand the task
When horizontal or loosely framed footage is adapted to vertical video, a presenter can drift toward the edges of the crop. In this workflow IntelliTrack follows a stable feature on the person and Tracker Match Move with BG only compensates that movement in the source footage. IntelliTrack requires Studio; the classic Point Tracker is an alternative to test on suitable footage. A downstream Transform defines the final scale and framing, keeping the presenter visually anchored in the chosen part of the vertical canvas without dozens of manual position keyframes.
The task only needs two main processing nodes. Tracker analyzes motion and converts it into positional correction; Transform handles final composition, scale and edge safety. Keeping those jobs separate makes the setup easy to understand and reuse. If the presenter should sit off-center to leave room for captions, change Transform Center without retracking the shot.
Node graph
Zoom into a branch, select a node and inspect its incoming connections.
Select a node to inspect its connections. Drag to pan; Ctrl/Cmd + wheel or + / − to zoom. Arrow keys move the view; Home fits the graph.On a touch screen, enable Move to pan and pinch the graph.

Assembly order
Feed the source clip to Tracker and choose a high-contrast stable feature on the presenter in IntelliTrack, usually part of the face, head or clothing that is not frequently occluded.
Track through the required range and inspect turns, fast movement and partial occlusions. If the track drifts, retrack that section from a more stable feature.
Keep the source footage in Tracker Background and choose Operation: Match Move with Merge: BG only. This output compensates the recorded motion relative to the chosen reference; FG over BG serves a different compositing task. Check that the selected feature stays still.
Use Transform after stabilization for the final vertical crop. Increase Size and adjust Center so the face and body sit correctly while preserving room for captions or social UI.
MediaOut receives the completed vertical reframing. The composition point can still be changed in Transform without recalculating the track.
Node parameters
The values below belong to this example. Use the descriptions to understand what each setting controls when adapting the graph to your footage.
The source composition uses IntelliTrack with a tracking point on the presenter. Operation is set to Match Move so subject motion drives the framing correction.
Transform performs the final vertical framing after Match Move. Exact values depend on source material, but the method is consistent: scale until the vertical frame is covered, then place the person at the intended composition point.
Troubleshooting
Do not track the mouth, eyes or another small feature that constantly changes shape; prefer a more stable area of the head or clothing.
Avoid points that are frequently covered by a hand, microphone or another person.
Do not scale without safety margin; compensation can expose empty edges if the crop is too tight.
Do not try to fix a bad track only with Transform. Repair the Tracker path first.
Do not force the face into the mathematical center when subtitles, logos or graphics need space on one side.
Avoid overly rigid compensation on handheld footage; retaining a little natural camera movement can look better than perfect lock-off.
Check the composition
