Source trim and placement.

Move a clip without changing which source moment appears.

Place the same source moment at different points in an edit. Two video layers both read source seconds 2–6, first at timeline 0–4 and then at 4–8. The repeated pouring action makes the independent source and timeline ranges visible.

A prompt to start from

Use Tesseract. Create an eight-second silent Tesseract editing study titled “Same / moment.” on Bone. Use the packaged water-pour film at right. Play its source interval from 2 to 6 seconds first at timeline 0–4 seconds, then repeat that exact source interval at timeline 4–8 seconds. Preserve separate sourceRange and activeRange values on the two Video layers. The second pass should visibly restart the same pouring moment, showing that timeline placement does not change the source trim.

Read the prompt

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.
