Chapter 4: Using SYNC HD 51
Frame Rate Restrictions with Video Reference
In Generator Preset mode, if the Clock Reference
is set to one of the two video inputs
(Video Ref In or Video In), Pro Tools is restricted
to generating time code at the incoming video
frame rate.
With the SYNC HD, the Time Code Rate you
choose is dependent on the video format:
• For NTSC, you can choose only 29.97 FPS
or 29.97 FPS DROP.
• For PAL, you can choose only 25 FPS.
In Generator Preset mode, if the Clock Reference
is set to one of the two video inputs, 24 fps can-
not be used as the SYNC HD time code format.
These restrictions are removed when not in
Generator Preset mode.

From Pro Tools:
