Content positioning.

Reframe the source inside a fixed visual container.

Move footage inside a fixed frame without moving the frame itself. Two matching windows use custom fit with identical scale and different content centers. The subject’s placement changes while the outer bounds remain aligned.

A prompt to start from

Use Strata. Create an eight-second silent Strata content-positioning comparison. Place two equal 812×584 coastal-video frames side by side on Bone. Both use identical custom content scale and synchronized footage. Keep the frame geometry fixed while the right version uses a different absolute contentCenter to shift the person right and leave more open space. Set “The frame stays. The focus moves.” in one line above. The difference must come from Custom media fit, not moving or resizing the layer.

A few useful details.
