How we make and test clips
All 236 example clips are generated by PromptJazz in SpeedReel at 480p and 16:9. Unless a library note below says otherwise, each is text-to-video with no reference images, 8 seconds long and unedited. Every prompt page names the model and the test date, for example “Made with Seedance 2.5 · tested Oct 2026”, and gives the clip's length. We review every clip frame by frame and write up the wording that failed and the fix.
The Chinese prompts on the zh-TW pages are beat-for-beat translations; the example clips were made from the English originals.

By library
- AI camera movement prompts
- Every move in a scene starts with the same scene paragraph, so the camera is the only difference. The clockwise orbit is mirrored left to right.
- AI lighting prompts
- The four genre swaps reuse a light layer word for word. One staging was refused by the provider and replaced.
- AI facial expression prompts
- The casts and looks are deliberately varied. One expression was refused by the provider in its first staging and was restaged.
- AI martial arts prompts
- Techniques are shot the way fight scenes cover them, not like training footage.
- AI video style prompts
- Every style renders the same rooftop scene, so the style block is the only difference, and the grid runs from least to most lifelike. Glitch art was dropped for vaporwave because its clips came out clean, with no glitches, and the copyright check refused takes of three styles until they described technique and a distinctive cast.
- AI film look prompts
- Grades, director and weather looks share one street walk; action looks share one rooftop leap. Four looks were refused for output likeness with the default cast and passed with a recast man; bleach bypass and cross-processed needed rewording.
- AI video text prompts
- Every clip spells its words exactly, with the text on screen from the first second. When the 【 】 brackets that mark on-screen text were drawn into the clip, “brackets” in the negative prompt or naming the word plainly fixed it. Clips the copyright check refused passed once the cast changed. Three clips are trimmed so they open on readable text, so this library shows real clip lengths instead of the 8-second beat bar.
