OpenStreetMap Code Swarm!
- OpenStreetMap Code Swarm in high quality (800×600, 4:24, mpeg4, 28.2Mb)
- OpenStreetMap Code Swarm in high quality with sound (36.1Mb)
- OpenStreetMap Code Swarm in medium quality (800×600, 4:24, mpeg4, 25.8 Mb)
- OpenStreetMap Code Swarm in medium quality with sound (33.7 Mb)
- OpenStreetMap Code Swarm in low quality (800×600, 4:24, xvid, 7.9 Mb)
- OpenStreetMap Code Swarm in low quality with sound (15.8 Mb)
This is my little surprise to all OSM devs!
After three days of try and error with the great Michael Ogawa’s code swarm, mencoder, subtitle editor, audacity and following some guides like this one, after 7 hours of frames rendering and countless hours of video compressing… here it is!
Unfortunately I’m not so into OSM history to insert sensible subtitles about “commit bursts” and I’m not sure about all the dates of API changes… if you want to help please contact me or comment!
How you can help:
- Tell me about relevant OSM dates that explains commit bursts
- Every circle represent a file, and all files in the SVN corresponding to some regex can be coloured differently (so we can, for example, have different colors for osmarender commits, tiles@home, core API, etc…; or, if wanted, different colors for ruby sources, js, html, etc..). I’m going to produce them for future videos, but obviously Regexs are appreciated
- I’m a real newbie on video compressing, so you can give me mencoder strings to encode the video in different or more attractive codec/quality. Consider that code_swarm outputs all frames in png, then I use raw output to merge them, insert the logo, insert the subtitles. After that I compress the raw file (here your help is needed!!!) and then I merge the file with the background music.
