Drop one video or multiple PNG frames here
MP4 / WebM / MOV, or separate PNG animation frames. PNGs are added in filename order and can be duplicated/reversed without importing them again.
Tip: solid white, black, or clearly contrasting backgrounds give the best cleanup results.

Quick Notes

Source frames per second only affects video extraction. PNGs are imported directly as frames. Duplicate active appends another copy of the active sequence; Append reverse appends that sequence backwards (for example 1-2-3-4-5-5-4-3-2-1). Preview frames per second only changes playback speed. Click-drag to paint active frames; Ctrl + Click toggles one frame.

Tips & Advice

What this tool does

Drop one animation video, or import multiple PNG frames.
Extract video frames at your chosen source frames-per-second rate, or use PNGs directly.
Activate only the frames you want in the loop.
Duplicate the active sequence or append it in reverse without re-importing files.
Preview the loop in real time.
Optionally remove the background.
Export the selected frames as a sprite sheet PNG.

Best source-video advice

Keep the camera locked. No zoom, no pan, no tilt, no dolly.
Keep the character centered and fully visible.
Use a solid or very simple background.
Avoid fire, dripping liquids, flowing cloth, or giant loose capes if you want easy loops.
Simple silhouettes and readable weapons work best for sprites.

Prompt idea — general walk cycle

Animate this exact character as a clean loopable walk cycle. The character stays perfectly centered and walks in place on screen. Full body always visible. Fixed camera, locked framing, constant scale, no zoom, no pan, no tilt, no dolly, no camera motion, no perspective change, no translation across the screen. White background, no shadows, no environment. Only the character moves. Simple readable walk cycle, subtle stepping, small arm swing, slight body bob, game asset style.

Prompt idea — strict top-down

Animate this exact character as a clean loopable walk cycle. Strict overhead top-down view, camera directly above, orthographic game asset feel. Maintain the same top-down silhouette during the entire animation. The character walks forward relative to its own body, but remains walking in place on screen. Character stays perfectly centered. Full body always visible. Fixed camera, locked framing, constant scale, no zoom, no pan, no tilt, no dolly, no camera motion, no perspective change, no translation across the screen. White background, no shadows, no environment, no cinematic motion. Only the character moves.

Background-cleaner advice

If your character is mostly green, try a purple or magenta background.
If your character is mostly purple, try a green background.
White on white and black on black are the hardest cases.
The cleanup here is a bonus helper. The main product is the sprite-loop workflow. For best results, plan your source background wisely.
