Usually, i use [pix_video] to get the video stream of a webcam.
[pix_film] is more designed to read a movie file from your hard drive.

If you need a value to quantify the movement in your webcam field, you
can use [pix_movement] (or [pix_movement2]) and the fourth outlet of
[pix_blob].
See 04.video/03.movement_detection.pd in the Gem examples (in the help
browser window) and the help patch of these objects.
