I've not had the opportunity to use this project yet, but https://github.com/nbedos/termtosvg seems to be another nice alternative. It provides the option of using templates that have playback controls or a progress bar. Also supports copying from the "terminal" like asciinema does.

Yes, termtosvg is a really good solution to this problem!

Here's an example with a pause/play button:

Was it intentional to make ASCIInema sound like "ass enema"?

thanks. now I will never be able to unsee that.

And save about a million bytes in bandwidth.
