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.

Try it in your agent.

Use this prompt as a starting point. Review the result, then ask for the details you want to change.

A prompt to start from

Use Tesseract. Create an eight-second silent Tesseract 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.

How do I try this with my agent?

Install or update Tesseract in a supported agent, attach your source files, and copy the prompt. Review the preview, then ask for the changes you want. The composition stays editable as you refine it.

Set up Tesseract by Mirage so you can create editable designs, edit videos, and make motion graphics in this agent’s environment. Read https://github.com/mirage-hq/Tesseract and check the requirements for this local or hosted environment. If it is supported, follow the official plugin or skills installation guide, use its required runtime version, verify the download checksum, and confirm a short preview renders correctly. Then ask what I want to make and which brand references or source assets I have. Keep the editable project and source assets with the finished render.
