Gophers at Work

A visualization of the Go programming language implementation over five years, from initial specification through Go 1.1.1.

The final video is on Vimeo.

Title screen made with Keynote, image editing with Pixelmator, final composition with iMovie.

Generating the Video

Using gource 0.40 and ffmpeg 1.2.1.

hg log -r 4:release --style gource.style `go env GOROOT` > go.log

gource gource.conf

ffmpeg -y -r 25 -f image2pipe -vcodec ppm -i gource.ppm -vcodec libx264 -preset ultrafast -pix_fmt yuv420p -crf 1 -threads 0 -bf 0 gource.mp4

I ran into some out-of-order log entries, possibly caused by different time zones. My fix was to modify the default gource.style to use localdate and then use BBEdit to sort go.log.
