Welcome to the comma.ai Programming Challenge!

Your goal is to predict the speed of a car from a video.

  • data/train.mp4 is a video of driving containing 20400 frames. Video is shot at 20 fps.
  • data/train.txt contains the speed of the car at each frame, one speed on each line.
  • data/test.mp4 is a different driving video containing 10798 frames. Video is shot at 20 fps.


Your deliverable is test.txt. E-mail it to [email protected], or if you think you did particularly well, e-mail it to George.


We will evaluate your test.txt using mean squared error. <10 is good. <5 is better. <3 is heart.
