I'm Italian and my english is not very well: sorry!
I like to go in a track with my bike, and I use a camera like GoPro for recorder my camera-car videos.
I’ve one system of data logger that archive RPM and SPEED data with a 20 Hz of framerate in a simple SD card. (I can trasform this data in all format: csv, xml, txt or excel.)
I want impression speed ad RPM in the video with After Effects.
