I get to make these videos at work. I edit them using #Kdenlive and had to use the #rotoscoping tool to edited a #MapleBug that wandered on the scene. I use #AudioRecorder from #Fdroid to capture audio then sync in kdenlive. After it all I use #Handbreak to reduce the video size to about 3 to 4 mb from 45mb to post it on a display say city Hall.
#OpenSource is awesome
