FAQ

Is video uploaded for trimming?

No. ffmpeg.wasm loads and encodes video locally in your browser.

How do I trim a clip?

Load a video on the Editor subview, set in and out points on the timeline, then export.

Can I export GIF or APNG?

Yes. Choose animated export options and tune frame rate and size in the Export subview.

Why is export slow?

Long clips and high resolutions are CPU intensive in WASM. Trim shorter segments for faster GIF exports.

Which input formats work?

Common containers such as MP4 and WebM depend on browser and ffmpeg.wasm support.

Where are default export settings?

Open the Settings subview to set defaults stored locally on this device.

Can I remove audio from a GIF export?

GIF and APNG exports are silent animations. Use Convert for audio-only outputs if needed.
