Asciinema – Record and share your terminal sessions
This is really cool, and if I wanted to host a demo on a public website or something like that (attempting to keep bandwidth use down), I would use it in a heartbeat.<p>My use case for terminal demos is very different from that.  Usually I&#x27;m just recording something short and emailing it to one person.  Bandwidth savings do not accumulate across many website visitors, and simple is perfect.<p>The nice thing about video is I can just email it.  I don&#x27;t need to host a web server instance for playback.  Even at very high quality settings (&quot;ffmpeg -qscale:v 1&quot;, nothing blurry about it) the resulting video is only about 1MB&#x2F;minute (80x24 term, h264 or h265).<p>Here&#x27;s my demo workflow, in case folks are curious:<p>1. simplescreenrecorder to record terminal window + voice.<p>2. ffmpeg -i recorded.mkv -vcodec libx264 -qscale:v 1 -acodec aac encoded.mp4   # or s&#x2F;264&#x2F;265&#x2F; for slightly better compression, if the receiver has new enough codecs<p>3. Email the video or whatever.<p>That&#x27;s it.
