Appendix B, Matrox RT.X2 Workflows
Overview
This appendix provides general information about using various Matrox RT.X2
project presets and codecs for working with different types of projects in Adobe
Premiere Pro. Workflow diagrams and descriptions are used to help explain the
specific workflow details.
Working with SD “24P” material
Matrox RT.X2 allows you to choose a Premiere Pro preset to work with SD
material originally acquired at 23.98 fps. When you select the Matrox 486p @
23.98 fps project preset, you can edit SD material as 23.98 fps progressive video
as long as the source video was originally acquired at 23.98 fps. This includes
video that was captured to tape by a DV camera capable of shooting 486p @
23.98 fps video, and Panasonic P2 video shot as 486p @ 23.98 fps and recorded
directly to disk as .mxf files. You cannot use the 486p @ 23.98 fps project preset
to capture or edit video that was originally acquired as NTSC or PAL.
Regardless of it’s origin, SD material that is acquired at 23.98 fps must undergo a
format conversion to NTSC (486i @ 29.97 fps) when it is recorded to tape, or
recorded to disk in the case of .mxf files. This means that the output from your
source device and input to Matrox RT.X2 is always NTSC. Your source device
outputs the 23.98 fps material as NTSC by applying a pulldown method when it
records the material to tape or disk.
Some DV cameras that are capable of shooting 23.98 fps progressive video have
the option of performing either a standard or advanced pulldown for recording
material to tape or disk. In order to use the video with Matrox RT.X2, we
recommend that you set your DV-1394 device to use advanced pulldown (called
24PA or 24P Advanced mode on some devices) to convert the footage to
29.97 fps interlaced video. Matrox RT.X2 will then apply an advanced reverse
pulldown method to convert the source video to 486p @ 23.98 fps for editing
clips in Adobe Premiere Pro.
¡ Important
When using a Panasonic P2 camera to shoot 486p @ 23.98 fps
material for use with Matrox RT.X2, you must set the camera to Advanced
mode (486/24pA).
The output from your 486p @ 23.98 fps project on Matrox RT.X2 is always
NTSC. Matrox RT.X2 provides the option to apply either an advanced pulldown
or standard pulldown. In most cases, you would want to perform an advanced
2:3:3:2 pulldown only if your DV video requires further processing or if it is to
be archived. Otherwise, a standard 2:3 pulldown should be used when you export
your 486p @ 23.98 fps project to tape. For more information about standard 2:3
pulldown and advanced 2:3:3:2 pulldown, see
Standard and Advanced Pulldown
