Adjust contrast and color with RGB curves.
Use a master curve to adjust contrast or individual red, green, and blue curves to change color. Ask your agent to adjust shadows, midtones, or highlights, then refine the editable curve points.
Sample footage generated with Seedance 2.5. The demonstrated correction is applied with native Tesseract controls.

A prompt to start from
Use Tesseract to grade this coastal footage with RGB curves. Give the midtones more definition, keep texture in the darkest areas, and warm the highlights slightly without clipping them. Keep the pale rocks close to neutral. Compare the original and revised frame, and leave the master and individual channel curve points editable.

- Master curve
- Shape the overall relationship between dark, middle, and bright tones.
- Channel curves
- Adjust red, green, or blue in specific tonal regions.
- Control points
- Revise the curve’s points without changing the source footage.
A few useful details.
How are curves different from a contrast control?
A contrast control makes a broad change. Curves let you choose which tonal regions move and how much—for example, opening shadows while holding the brightest tones in place.
Can I adjust color without affecting every tone equally?
Yes. Individual red, green, and blue curves let you treat shadows, midtones, and highlights differently. Review the result for unwanted casts and clipping.
Can the curve points animate?
The current RGB curve point arrays are static. Your agent can revise those points between previews; do not assume every grading control supports keyframe animation.
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.
Where does the video render?
Tesseract renders in the environment where your agent runs it, including supported local computers and hosted Linux environments. The engine is free; your agent’s subscription or usage costs are separate.

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.
