FAQPage Schema

How do I record a CLI demo video for a README file?▼

Recording a CLI demo video involves capturing terminal sessions with asciinema and converting them using agg and ffmpeg. This pipeline automates the creation of polished GIF and MP4 demo videos directly from your command-line or TUI interactions.

Can I record interactive TUI sessions for a demo video?▼

Yes, you can record interactive TUI sessions using tmux integration. The recording process orchestrates asciinema to capture the live terminal interface, ensuring that interactive elements and real-time user inputs are accurately preserved in the final video output.

Does this demo recording workflow support Rust and Python tools?▼

Yes, the demo recording workflow supports Rust, Python, TypeScript, and Bash tools. It handles both direct CLI subprocess recordings and interactive TUI sessions, allowing you to generate demo videos across multiple programming languages and execution environments.

What is the best way to convert asciinema recordings to MP4?▼

The best way to convert asciinema recordings to MP4 is by using a pipeline that first transforms the cast file into a GIF via agg, then converts that GIF into an MP4 video using ffmpeg, ensuring high-quality video output for your CLI demos.

How do I design pacing and acts for a terminal demo?▼

Designing pacing and acts for a terminal demo involves structuring your recording into clear segments. The process includes detailed guidance on act design and pacing, ensuring your CLI or TUI tool demonstration flows logically and is easy for viewers to understand.

Do I need ffmpeg installed to generate terminal demo videos?▼

Yes, you need ffmpeg installed to generate terminal demo videos because it handles the conversion from GIF to MP4 format. The recording pipeline relies on ffmpeg alongside asciinema and agg to produce the final high-quality video outputs.
