Working with HD projects
¦ Note Although Matrox RT.X2 SD does not support working with HD projects,
you can capture and import HDV 1080i/p clips to an SD project on RT.X2 SD as
explained in
“Capturing HDV and SD material on Matrox RT.X2 SD” on
page 182 .
Matrox RT.X2 lets you capture native HDV material over the 1394 interface and
capture HD analog component input to MPEG-2 I-frame HD format. Native
HDV and MPEG-2 I-frame HD clips can be mixed in real time in the same HD
project. You can also import SD clips to your HD project and Matrox RT.X2 will
upscale the clips in real time as explained in
“Mixing SD and HD clips in a
project” on page 20 .
¦ Note When working with a 720p or 1440× 1080p project, you can capture
native HDV material over the 1394 interface, but analog component capture is
not supported.
Matrox project presets are provided for capturing to native HDV or MPEG-2
I-frame HD format, but regardless of which preset you choose to create your
project, you can change your capture settings at any time to switch between
capturing native HDV using DV-1394 input and capturing HD analog component
video to MPEG-2 I-frame HD format. For more information about capturing to
MPEG-2 I-frame HD format, see
“Using the Matrox MPEG-2 I-frame HD
codec” on page 183 .
When working with a 1440 ×1080i/p project, you can import Sony XDCAM EX
1080i/p HQ-mode (1920× 1080) and 1080i/p SP-mode (1440× 1080) .mp4 files
for realtime playback. You can also choose to import Panasonic P2 .mxf files and
Sony XDCAM EX 720p .mp4 files to your 720p project for realtime playback.
When needed, Matrox RT.X2 will convert the clips to your project’s video format
by removing the redundant frames when the clips are played back on the
timeline.
When your edits are complete you can export your project to an HDV device over
the 1394 interface (for a 1440× 1080i/p project only), or export to tape using your
Matrox RT.X2’s HD analog component output. You can also choose to
downconvert the video to NTSC or PAL to record to SD tape. The format in
which you can export depends on your project’s video format as explained in
“Supported master output formats” on page 188 .
