SMPTE Film Sync: click to display the time ruler, cursor position, and selection 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: click to display 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: click to display 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: click to display 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.

SMPTE 30: click to display the ruler in hours:minutes:seconds:frames with a frame rate of 30 frames per second.

This rate is exactly 30 fps and is commonly used when synchronizing audio applications such as multitrack recorders or MIDI sequencers. This format should not be used when working with video.

Audio CD Time: click to display the ruler in hours:minutes:seconds:frames with a frame rate of 75 frames per second for creating Red Book CDs.

If you want to display disc-at-once CD track numbers in the Time Display window, right-click the Time Display window and choose CD Track Position from the shortcut menu. In this mode, the Time Display will show track numbers and the running time for each track. Negative values indicate the pause time before a track:
