What raw-video-processing does

The skill streamlines rough screencast editing using two Python scripts managed by uv. It first triggers remove_silence.py. That script cuts out dead air longer than 0.5 seconds without re-encoding the stream. The aggressive -20dB threshold treats keyboard typing and ambient noise as silence, keeping pauses out of the finished recording.

Once silent sections are gone, speed_video.py applies a 1.2x playback rate and re-encodes the file through FFmpeg. Without ffmpeg and uv pre-installed on the machine, processing cannot run. Order matters here. Speeding up the clip beforehand changes audio pitches, which confuses the silence detector and cuts spoken parts.

What it helps with

  • cut silent gaps and keyboard clatter from raw screencasts
  • speed up edited screen capture video to 1.2x
  • preview cut timestamps using --dry-run before rendering
  • trim long software walkthroughs without manually slicing clips

Example prompts for the agent

  • Remove dead air from demo.mp4 and boost playback speed to 1.2x
  • Run remove_silence.py on screencast.mp4 with --dry-run to inspect timestamps
  • Strip pauses and typing noise from tutorial.mp4 using a -20dB threshold

Questions about raw-video-processing

How do I install raw-video-processing in Claude Code?

Run npx skills add zc277584121/marketing-skills --skill raw-video-processing -a claude-code in your terminal.

Why must silence removal run before speeding up the clip?

Silence detection relies on intact frequencies from the original audio track. Speeding up the clip first warps the audio, causing the detector to misidentify speech or overlook quiet pauses.

Which system dependencies are required?

Both ffmpeg and uv must be present in your system environment alongside Python 3.12.
