Applying pulldown in HD sequences

Depending on your HD sequence settings, Matrox Axio applies a pulldown
method so that you can capture an HD video format (input format) that is
different from your sequence's format. For example, when working in a 1080p @
23.98 fps sequence, you can capture 1080i @ 29.97 fps source video and use it in
your 1080p @ 23.98 sequence as long as the material was originally acquired at
23.98 fps or 24 fps. This includes film footage that was shot at 24 fps, then
transferred to tape as 1080i @ 29.97 fps using a telecine process. In this case,
Matrox Axio performs a standard reverse pulldown when it captures 1080i @
29.97 fps material for use in a 1080p @ 23.98 fps sequence.
You can output your completed 1080p @ 23.98 fps sequence to 1080PsF @
23.98 fps, 1080i @ 29.97 fps, or NTSC format. To output the sequence as 1080i
@ 29.97 fps or NTSC, a standard 2:3 pulldown is performed to convert your
video to the appropriate format.
Remarks
• Material shot by an HD video camera at 1080i @ 29.97 fps (non-telecined
material) is not suitable for use in a 1080p @ 23.98 fps sequence. Instead,
use a 1080i @ 29.97 fps sequence for working with this material.
• If you want to capture and edit HDV 1080p @ 23.98 fps clips, you can create
a 1440×1080p @ 23.98 fps sequence, which supports capturing HDV
material natively over the 1394 interface using the Adobe Premiere Pro HDV
capture format. You can output your completed 1440 ×1080p @ 23.98 fps
sequence to 1080PsF @ 23.98 fps, 1080i @ 29.97 fps, or NTSC format. To
output the sequence as 1080i @ 29.97 fps or NTSC, a standard 2:3 pulldown
is performed to convert your video to the appropriate format.
