System information
Format Description
Measures and Beats Displays the ruler in measures.beats.ticks, where 64 ticks = 1 beat.
To set the tempo and number of beats per measure, use the Ruler tab
in the Project Properties dialog. For more information, see "Setting
Project Properties" on page 53.
Feet and Frames
16mm (40 fpf)
Displays the ruler in feet+frames at a rate of 40 frames per foot.
Feet and Frames
35mm (16 fpf)
Displays the ruler in feet+frames at a rate of 16 frames per foot.
SMPTE Film Sync IVTC
(23.976 fps)
Displays the ruler in hours:minutes:seconds:frames with a frame rate
of 23.976 frames per second. This frame rate matches the frame rate
used when the inverse telecine process removes pulldown from
progressive-scan 24 fps (24p video).
This format will display running film time correctly if you will be
transferring your project to film. To see running project time, use
SMPTE Film Sync (24 fps) or SMPTE Drop (29.97 fps).
SMPTE Film Sync (24
fps)
Displays the ruler in hours:minutes:seconds:frames with a frame rate
of 24 frames per second. This frame rate matches the standard
crystal-sync 16/33 mm film rate of 24 fps.
SMPTE EBU (25 fps,
Video)
Displays the ruler in hours:minutes:seconds:frames with a frame rate
of 25 frames per second. This is known as SMPTE EBU (European
Broadcasting Union) because European television systems run at 25
fps.
Use SMPTE 25 EBU format for PAL DV/D1 projects.
SMPTE Non-Drop
(29.97 fps, Video)
Displays the ruler in hours:minutes:seconds:frames with a frame rate
of 29.97 frames per second, which leads to a discrepancy between
real ("wall clock") time and the SMPTE time, because there is no
compensation in the counting system as there is in Drop Frame.
Use SMPTE Non-Drop format for NTSC D1 projects that will be
recorded on master tapes striped with Non-Drop timecode.
SMPTE Drop (29.97 fps,
Video)
Displays the ruler in hours:minutes:seconds;frames with a frame rate
of 29.97 fps to match the frame rate used by NTSC television
systems (North America, Japan).
Use SMPTE Drop Frame format for NTSC DV/D1 projects.
Both SMPTE Drop and SMPTE Non-Drop run at 29.97 fps. In both
formats, the actual frames are not discarded, but they are numbered
differently. SMPTE Drop removes certain frame numbers the
counting system to keep the SMPTE clock from drifting from real
("wall clock") time. The time is adjusted forward by two frames on
every minute boundary except 0, 10, 20, 30, 40, and 50. For example,
when SMPTE Drop time increments from 00:00:59.29, the next value
will be 00:01:00.02.
