Stillsplice

Stillsplice finishes image sequences you have already made. Import your stills, set their timing, then make an H.264 MP4 video, a looping GIF and a CSV timing sheet from the same timeline.

FINISH A SEQUENCE
Import PNG, JPEG and device-supported HEIC images through Android's file picker. Numbered filenames sort naturally, so frame 2 comes before frame 10. Check missing sequence numbers and mixed image sizes, reorder stills, and adjust each hold from 1 to 240 frames. Undo and redo sequence edits, set every hold at once, or compare a still with the previous one using a translucent overlay.

CONTROL THE LOOP
Choose forward, reverse or ping-pong playback at 6 to 30 FPS. Ping-pong does not repeat turning endpoints. Use a square 1080 x 1080, landscape 1920 x 1080 or portrait 1080 x 1920 canvas. Up to 500 stills per sequence. Preview and export use the same timing plan.

KEEP THE ACTUAL FILES
Create MP4, GIF and a timing CSV together. GIFs use a 960-pixel long edge and cumulative centisecond timing to avoid rounding drift. Preview saved videos, GIFs and CSVs, share individual files, or save and share a ZIP package. Exports stay with their project and show whether they match the current edit.

YOUR OWN WORKSPACE
Projects and imported copies are saved on your device. Start empty with your own files, or try the optional original paper-koi sample. The tablet workspace places the image stage and frame grid beside the editing and export controls.

One purchase includes every feature. No account, subscription, ads, analytics, camera, microphone or developer-operated upload. Delete a sequence to remove its local source copies and exports. Files you choose to export are controlled by their destination.

Stillsplice finishes existing images. It does not capture photos, draw artwork, add sound or interpolate between imported frames. Android 9 or later.
