 These options set parameters of the mixer on the video capture card.
 They will have no effect, if your card doesn't have one.
+For v4l1, 0-65535 is a valid range. For v4l2, the valid range is
+0 to 100, and 50 maps to the default value of the control, as reported
+by the driver.
 .IPs immediatemode=<bool>
 A value of 0 means capture and buffer audio and video together
 (default for MEncoder).
