6. Continue clicking the marking point on every frame until you
capture all the data you need or until the video doesn't step
anymore.
Observe that the graph and table are updated with each mouse click.
Note: In order for MultiLab to automatically move to the next step after one mouse
click, the Consecutive option in two-body motion must be selected (the default
option)
Two-body motion
Use the left mouse button to mark the first body and the right mouse button to mark
the second body.
You can mark two-body motion in two ways: simultaneously or consecutively. In the
simultaneous method you mark the two bodies alternately on every step of the
marking process. In the consecutive method you finish marking the whole motion of
the first body and then repeat the process with the second body.
Simultaneous marking
1. Click Video Analysis on the menu bar, point to Two-body motion,
then click Simultaneous
2. Proceed as in one body motion except that in step 5 right click to
mark the first body and left click to mark the second body
MultiLab waits for both right and left mouse clicks before moving to the
next frame
3. Keep clicking alternately with the right and left mouse button at
every step
Consecutive marking
1. Click Video Analysis on the menu bar, point to Two-body motion,
then click Consecutive
2. Proceed as in one body motion until you finish marking the first body
3. Click Go to first
