3) Method 3 — Manual Masking (for non green/ blue background)

For short clip editing, use manual masking for instant results. Draw a shape according to the subject and place it as the background. Suitable when the chroma key is not available.

  • Step 1: Place the subject layer on top and the background layer at the bottom.
  • Step 2: Select the subject layer & click on layer control
  • Step 3: Go to the Mask/Shape/Path option
  • Step 4: If the subject is complex, select mask shapes like rectangle, ellipse, triangle, and manual brush.
  • Step 5: Animate masks if the subject moves.
  • Step 6: Use feathers and refine for a natural look.
  • Step 7: If the subject has a complex shape, then use multiple layers of masks, like a mask for the nose, a mask for the hair, and a mask for the hands.
  • Step 8: Now preview your masking, and you can export it.

Advanced tips & troubleshooting

  • Use garbage matte first: a rough mask to remove outlying green zones, then chroma key for fine removal.
  • Fix green spill: Despill tool / reduce green channel using color wheels / selective color correction.
  • Holes in subject: duplicate original layer, place below keyed layer, use blend/opacity to fill thin holes (careful).
  • Edge jitter / mask pops: increase mask keyframe density where motion is complex; turn on motion blur on the subject layer if available to hide small pops.
  • Soft hair edges: try a small blur on the subject, then an unsharp mask on the subject layer (subtle) to restore crispness.
  • Export with transparency: check if your Alight Motion version supports WebM/PNG sequences with alpha. If not, export on a solid color and use external tools to convert to alpha if possible.
