talks-reducer 0.3.4

CLI for speeding up long-form talks by removing silence

Talks Reducer

Talks Reducer shortens long-form presentations by removing silent gaps and optionally re-encoding them to smaller files. The project was renamed from jumpcutter to emphasize its focus on conference talks and screencasts.

Example

• 1h 37m, 571 MB — Original OBS video recording
• 1h 19m, 751 MB — Talks Reducer
• 1h 19m, 171 MB — Talks Reducer --small

Changelog

See CHANGELOG.md.

Install GUI (Windows, macOS)

Go to the releases page and download the appropriate artifact:

• Windows — talks-reducer-windows.zip
• macOS — talks-reducer.app.zip (but it doesn't work for me)

Install CLI (Linux, Windows, macOS)

pip install talks-reducer

Note: FFmpeg is now bundled automatically with the package, so you don't need to install it separately. You you need, don't know actually.

The --small preset applies a 720p video scale and 128 kbps audio bitrate, making it useful for sharing talks over constrained connections. Without --small, the script aims to preserve original quality while removing silence.

Example CLI usage:

talks-reducer --small input.mp4

When CUDA-capable hardware is available the pipeline leans on GPU encoders to keep export times low, but it still runs great on CPUs.
