First of all, this sequence referred to was processed with outdated versions of FFMPEG, that unfortunately detorriated the image quality, and was not detected by me until a new version of FFMPEG had solved this.
My process is to record movies while driving, using action cameras set to "record while moving", and post-process to image sequences using FFMPEG and a series of python scripts. Both my cameras are set to record in 1080p (sequences before September 1 was recorded with one camera), and camera set up are to cover as large area as possible, hopefully to cover 360º sometimes in the future. Quality on images might vary as the cameras are mounted outside on a moving vehicle, mist, rain, dust and speed will all have a negative factor on the images.
Leadershipboard is not important for me, I seem to be the most productive in Brazil, but if somebody was to dethrone me, than I'll rest in peace that I am not the nerdiest nerd in Brazil any more.
My goal is to have a coverage that competes with Google Streetview, and that this coverage can benefit OpenStreetMap.
If people are bothered that I get a high position on the Leadershipboard, than I invite them to cover the areas I currently are covering, so that I don't need to.
