FFmpeg Studio — In-Browser Video & Audio

In [1]:

# 1. Drop a file

Pick a video or audio file from your machine. Nothing is uploaded — ffmpeg runs locally as WebAssembly. First load fetches ~30 MB of WASM from a CDN.

Idle — engine loads on first run

# 2. Pick an operation

Target format:

Re-encodes the input to the chosen container/codec using sensible defaults.

Width: Height:

Leave one blank to keep aspect ratio. Width/height round down to the nearest even number.

Start (seconds): End (seconds):

Trim by seek timestamps; output keeps the source container.

Silence threshold (dB): Min duration (s):

Drops segments quieter than the threshold for longer than the min duration. Re-encodes audio (and re-muxes video) — same container.

Bitrate:

Strips the video stream and re-encodes audio to MP3.

FPS: Width: Start (s): Duration (s):

Two-pass conversion with a palette for crisp colors.

Arguments (use input and output.ext):

Power-user mode. Whatever you'd pass to ffmpeg. The downloaded file's name comes from the output.* argument.
