The visualization for the preliminary tool (not yet uploaded to remote) feels a bit sped up. Having an accurate frame per second, or fps value derived from video metadata/video data file constants may be important for syncing IMU data with video data, so this is an important issue to investigate.

Equation : y = mx + b
y = timestamp
x = frame number
m = frame rate
b = offset (user typed in?)
