Apple Final Cut Pro HD (4.5): New Features - Manual (Page 50)

50 Chapter 1 Using DVCPRO HD
Using 30 fps Timecode With 720p30 and 1080i60
1080i60 and 720p30 formats both use 30 fps timecode. 720p30 has one timecode
number per progressive frame, while 1080i60 has one timecode number per two
interlaced fields.
Note: The option to show drop frame timecode is only available if your media file has
a frame rate of 29.97 fps. 30 fps media files can only have a time display of 30 fps,
non-drop frame timecode.
Using 24 fps Timecode With 720p24
On tape, 720p24 records 30 fps timecode. Even though the frame rate of 720p24 media
files is 24 fps (or 23.98 fps), the timecode track is captured at 30 fps. In Final Cut Pro,
you may choose to view this timecode in two ways:
• Source time: 30 fps timecode from the source media file, which corresponds to the
original source tapes
• Clip time: 24 fps timecode displayed based on the 24 fps (or 23.98 fps) frame rate of
the media file
Important: The frame rate (or timebase) of a media file is independent of its timecode
track rate, although they are usually related. 720p24 is an example of a media file that
has a frame rate and a timecode rate that differ.
Using Graphics and Effects With DVCPRO HD
Creating Graphics for HD Projects
Creating graphics and still images for high definition video projects is the same process
as for standard definition video. To determine the image dimensions for your sequence,
follow the guidelines below.
Note: Unlike standard definition video formats, which use rectangular pixels, high
definition video formats use square pixels. You don’t have to worry about adjusting
high definition image dimensions before importing your graphics into Final Cut Pro.
Sequence preset Still image dimensions
1080i 1920 horizontal x 1080 vertical
720p 1280 horizontal x 720 vertical
