Slow conversion speed

[nick-george]

Hi there,

On an Intel Core i5-6500 CPU @ 3.20GHz, it takes over four minutes to convert an 11 second recording into a video.

Is there any way to speed this up?

Thanks!

Another conversion of the same recording, but with a custom resolution took much longer:

$ time ttyrec2video --size 282 75 ../ttyrecord
Reading ../ttyrecord ...
ttyrec length: 0:00:10.709228 (222 distinct frames)
Writing ../ttyrecord.mp4 ...

real	43m46.617s
user	43m47.831s
sys	0m1.803s

I can see that one CPU core is maxed out during the process, but I can't see exactly what calls are taking up all the time.
