How Do I Give Each Tracked Video Region Its Own Effect?

To give tracked regions different video effects, add BOXES in BeamTracer Performer and choose FOLLOW → FACE + HANDS. Put MASK below BOXES, choose SHAPE → BOXES, and set DEAL → EACH. The enabled effects below MASK become a pool: each detected box receives one treatment while the surrounding video stays visible.

One moving picture, three treatments. Thermal colors the face, ASCII rebuilds one hand from characters, and Duotone recolors the other. The effects follow the detected regions.

How do I build a separate effect for the face and each hand?

Start with a clear view of a face and two hands. Keeping some space between them makes the result easier to read. The example uses TRINA · HANDS, which is available directly in the FX Rack.

The order is VISUAL SOURCE → BOXES → MASK → THERMAL → ASCII → DUOTONE. MASK changes how the effects below it reach the picture. An effect above MASK still processes its input normally.

What does DEAL EACH change?

EACH distributes the effects below MASK across the detected boxes. With ALL, those effects form one chain applied inside the masked regions. Thermal followed by ASCII and Duotone can therefore look very different from three separate treatments.

These assignments belong to the current box order. They are not named roles such as “always give the left hand ASCII.” If a hand leaves the picture or detections change, an assignment can move. Check an entire gesture before recording a take that depends on a particular arrangement.

For the opening example, use these starting values:

Set the mask’s outline color to #91fff0 and GLOW SIZE: 0.012 for the mint edges shown here. Grow and edge widths are relative controls; check them again when changing the source framing.

Can I turn the boxes into circles?

Choose REGION → CIRCLE inside MASK. The detector still follows rectangular face and hand bounds, but the treatment is clipped to a circle within each region. The tracking brackets can remain visible around it.

Only REGION changes here. The effect pool and source interval match the rectangular example.

Use DIAMOND, HEXAGON, RING, or HEART for another cutout. Tight shapes can crop a fingertip or the sides of a face. Increase GROW a little, or return to RECTANGLE when the full gesture matters more than the cutout.

How do I magnify a tracked face or hand?

Put ZOOM below MASK and choose STYLE → MAGNIFY, CENTER → BOX, and AMOUNT: 2.2. The zoom centers on each region instead of the middle of the screen.

This is a different two-effect pool: ZOOM → THERMAL, with DEAL: EACH and REGION: HEXAGON. Zoom is one of the treatments being dealt; it is not an extra magnification added to every treatment.

For the same magnification on every box, leave only ZOOM enabled below MASK and use DEAL → ALL. Start near AMOUNT: 1 and raise it while checking the eyes and fingers. Strong magnification can make an otherwise small movement jump across the window.

How do I keep the tracking readable in the export?

Review a short saved clip with the hands moving apart, overlapping, and leaving the frame. A good still does not show whether the mask follows the whole gesture. Reduce glow if the outlines hide the fingers, and turn off extra tracking decorations until the effect regions are easy to follow.

The examples are silent and show fixed assignments. EACH · BEAT is available when you want the pool to re-deal on beats; test it with your chosen music before recording. The tracking and masking guide covers the other mask shapes and tracking sources. The color-tracking tutorial shows how to target a selected color instead of a face or hands.
