cast-me

cast-me is a CLI app designed to automate the transcoding of video files (presumably screencasts). I originally created it due reduce the enormous file size of my quicktime screencasts.

Feature set it pretty thin at the moment. It does what I need it to do (for now). See RoadMap for ambitions - when time / motivation permits.

Check out the feature set below!

I've dialled in a single preset for coding screencasts. FPS at 8 with no loss in the number of pixels. On longer .mov files, it's usual to see ~5% of the original file size.

🌎 Road Map

• Remove dependency on CLI prompt libraries
  • Re-implement using Ink react-renderer.
• Use Redux-Toolkit and MemoryRouter to manage state of application.
• Flesh out configuration options
  • FPS
  • Bitrate
  • Concatenate (with timecode meta output)
  • Transition
  • Overlay
  • ...
• Presets
• Local configuration files
• Web interface
• Youtube Upload
• Versioning / NPM publishing
• commander for CLI flag UI design.
• Use Typescript
  • In hindsight, I much - much prefer developing with Typescript.

ffmpeg

These links formed some of my initial education into ffmpeg. cast-me now delegates to fluent-ffmpeg - a very convenient wrapper for node.
