Files and settings

Editable sample: 12 seconds from the 2009 U.S. inaugural address, marked public domain under U.S. law. Source and license · Steve Jobs at Stanford ↗ · Jensen Huang speeches ↗

Drop local files here. Up to three clips; source size and duration follow this device’s budget above. Source up to 1080p.

Time range
The start is included. Compressed audio can contain codec padding; tiny duration differences are normal.
Output frame
Use even dimensions. Native video: up to 1080p; WASM video: up to 720p, including portrait 720×1280. Frame captures can use up to 1080p.
Video format and quality
Bitrate is a target, not an exact file-size promise. Native supports up to 60 FPS, WASM up to 30 FPS; unsupported settings are rejected rather than silently changed.
Rotate, flip, then crop
Coordinates refer to the rotated/flipped full frame. Drag the rectangle in the preview or enter exact numbers.
Audio settings
Opus may require 48 kHz. MP3 at 16/24 kHz is limited to 160 kbps; use 44.1/48 kHz for higher MP3 rates.
Processing method and compatibility

WASM first use loads about 32 MB from this site. Captions and watermarks may load an additional 16 MB local font. Files are never sent for server conversion.

Your video stays on your device

Start with a local file or the attributed speech sample. The preview and actual output appear here.

Supported formats depend on the device. Unsupported or damaged files get an explicit message.

Getting started

Choose rotation/flip, adjust the rectangle in the transformed frame, then choose output dimensions.

Before you use the result

Device-aware sources: 256 MiB–2 GiB per file and 1–4 hours combined, up to three clips, one video and at most one audio track, up to 1080p source. Native long outputs can use local temporary storage; WASM has separate input/output/working-memory budgets and up to 720p/30 FPS. Actual codecs, memory and storage are checked; compression is not guaranteed.

Try an example

Rotate 90°, crop a smaller rectangle and inspect the exported orientation and edges.

How it works

Browser-native WebCodecs and Mediabunny are preferred; fixed single-thread FFmpeg WASM operations cover missing codecs and other supported tasks. Inputs and outputs are checked for dimensions, duration and expected tracks; long native results use bounded sample checks and can stream to private local temporary storage. No server conversion or arbitrary commands.
