Here's a frame by frame of the Dallas Q39 (118 and 3310 in same match).

118 is going for their 3 tote auto, 3310 is going for containers, and a team 932 (middle of field red side) is driving forward at a high speed in auto mode.

Frame 1 - Yellow lights on field illuminate
Frame 2 - Red/Blue DS stack lights illuminate
Frame 3 - Nothing
Frame 4 - 932 tips back and begins movement
Frame 5 - 932 continues to move
Frame 6 - 3310 begins to drop arms

Another frame by frame on Dallas F1 (118 grabbing from step, 148 auto)

Frame 1 - Yellow lights
Frame 2 - stack lights
Frame 3 - Nothing
Frame 4 - 148's arm moves
Frame 5 - 118 drops arms

From watching a few other matches, there is usually a different number of frames between lights and robot movement for teams like 118 and 3310.
