Media

Add media…

Every photo, video, or audio file gets its own movable timeline bar.

Drag any clip bar freely left or right; every other clip stays put and the ruler scale stays fixed. Scroll horizontally for later times. Arrow keys nudge 0.1 s, Shift nudges 1 s, and Alt nudges 0.01 s.

Audio layers

Add any audio file, then choose what it should do. Every track stays on this device and is mixed locally into the export.

Add audio…

Locally synthesized sound effects

Preview a generated sound before adding it. Sounds use oscillators and seeded noise in this app; nothing is downloaded.

Normalize audio files analyzes each imported file locally and targets a −1 dBFS peak. Volume and fades remain separate, editable controls.

Basic cleanup

Simple local pixel filters run in preview and export. They do not reconstruct missing detail.

Enable cleanupReduce grain (may soften detail)Sharpen

Select a photo or video layer.

Captions

TIMING Manual/imported captions stay on the project clock; captions generated from one clip move and retime with that clip.

Speech recognition runs on this device. Your media and generated text never leave the app, and every caption stays editable.

Import SRT / VTT

Generate captions locally

Choose one language for the whole source, or mark only the sections where the speaker changes language. The bundled model and your media stay entirely on this device.

Layout

MEDIA Select a photo or video layer to arrange it.

Repeat or reflect the selected media in equal-size sections. Layout stays attached to that layer and is included in preview and export.

Follow movement

Select a video, compose its first frame, then mark a distinctive area that stays visible. The local tracker follows pixel detail—not identity—and begins from your finished composition.

1. Choose the starting result

2. Mark a trackable area

Choose a clear, textured detail that remains visible, such as an eye, logo, or high-contrast edge.

3. Track and apply

How strongly to apply

Select a video layer to begin.

Fine-tune tracking

The tracking box is centered on the point you clicked. Increase its size if the area changes shape; use a shorter sample interval for fast movement. The preview shows the analyzed path and warns about weak matches.

Area X Area Y Area width Area height Check movement every Smoothing

Show only part of a layer (optional mask)

A mask hides everything outside a shape. After choosing one, drag it directly in the preview: drag inside to move, drag a square to resize, or drag the round handle to rotate.

Effects

BASE Select media, text, or a sticker to attach new effects; with nothing selected they apply to the base media.

Stack effects freely. For text and stickers, the browser automatically shows effects that follow the real visible edge—including transparent PNGs and rounded shapes.

Quick recipes

Text

Font

Fonts are bundled locally, so exports look the same everywhere.

Select any words inside a text box, then use B, I, or U. Ctrl/Cmd+B, I, and U work too.

Stickers

Use a design or upload any screenshot or picture. Text is optional and is never added automatically.
