The author stumbled upon Blender’s Video Sequence Editor (VSE) during a visit to Blender HQ. Despite having no prior knowledge of video editing, they decided to dabble with it and ended up contributing some performance optimizations to the VSE. They improved the timeline drawing, fixed issues with scopes, optimized ffmpeg libraries for audio/video reading and writing, optimized audio resampling, addressed “off by half a pixel” errors, added new filtering options, and optimized VSE effects. The author notes that they were able to accomplish more in two months on their own than they could have at an actual job, highlighting the complexities and limitations of working within larger organizations. They express their interest in continuing to tinker with Blender in the future.
