1080p/23.976: For HD online editing. Film-originated material can be
transferred to this format for editing and effects.

1080i/50: For HD broadcast
1080i/59.94: For HD broadcast
In the 30i NTSC and 25i PAL options, the i represents interlaced frames
played at 30 fps or 25 fps. An interlaced frame consists of two fields, each of
which contains one-half the scan lines of the frame. Interlaced frames are
standard for NTSC and PAL video media.

Not all project types and resolutions are available on all Avid editors.
Therefore, your system might not support certain project types or resolutions
that are covered in the documentation.
For more information on 23.976 projects, see “Working in a 23.976p NTSC
Project” on page 26 and “Capturing with Advanced Pulldown” on page 6.
Working in a 23.976p NTSC Project
Avid editing systems include a 23.976p NTSC project type. This project type
is especially designed for capture and output of digital audio that has been
transferred or recorded at 48 kHz, in sync with picture at 23.976 fps. A 23.976
project lets you maintain digital standards for all NTSC input and output at
23.976 fps. This rate can be downconverted to standard NTSC without further
audio slowdown. Audio captured at 48 kHz can remain at 48 kHz throughout
the project.
Select this project type for one of the following reasons:
Your audio and video sources have been shot at a camera rate of 23.976
fps using Advanced Pulldown (see “Capturing with Advanced Pulldown”
on page 27). This frame rate, sometimes referred to as 24p by
video-equipment manufacturers, is a DV-based standard-definition
format, with media being recorded and played back at 23.976 fps. Your
Avid editing application takes full advantage of the high-quality
progressive nature of this media, as you work in a 1:1 relationship with the
frame rate at which you captured your media.
