Storyboard to video (keyframe timeline)
Line up your keyframes, set how long each one holds and how it blends into the next, and export one MP4 — all in your browser.
How to use
- Add keyframes: several PNG, JPG or WebP images (sorted by file name), or one storyboard sheet that is cut into panels automatically.
- On the timeline, set the hold time, transition length and type for each keyframe — or pick a pacing preset.
- Preview the first seconds in low resolution, then create the full MP4 and download it.
Storyboard to video (keyframe timeline)
This is limited animation: keyframes plus in-betweens. Between two keyframes the tool can only blend or warp the pixels you drew (cross dissolve, zoom, dip, or optical-flow morph, the same algorithm as the Transition Clip Maker). It does not invent movement that is not in your drawings. For big motion, draw more keyframes — about one every 0.1–0.2 s, or 2–4 extra in-between poses for a single action. Dialogue and small changes work with one keyframe every 0.5–1 s; normal action with one every 0.3–0.5 s.
A storyboard sheet is split by finding the background gutters between panels; caption text, SHOT numbers and timecodes under each panel are trimmed off automatically, and a slider ignores an extra label strip at the bottom of each panel. You can also use an even rows × columns grid, draw boxes by hand or delete boxes before applying. Up to 200 keyframes and 300 seconds per video; long, high-resolution videos need a fast device, and the tool tells you before you start.
Frequently asked questions
Is this an AI video generator?
No. It is keyframe in-betweening, not AI video generation. The bigger the motion, the more keyframes you should draw (for big action, about one every 0.1–0.2 seconds). The tool will not invent in-between movement you did not draw.
Why do I see a yellow warning between two frames?
The two keyframes are too different for a clean in-between, so the morph may look ghosted or blurry. Add keyframes between them, or switch that transition to dissolve or a dip.
Can I add music?
The video is silent. Use Add Music to Video afterwards, and Vertical Video or Add Subtitles if you need them.
Are my images uploaded?
No. Everything, including the cutting of storyboard sheets and video encoding, runs in your browser, and it keeps working offline once the page has loaded.
