Capturing HDV and SD material to edit in SD on
Matrox RT.X2
If you want to deliver in SD but take advantage of the superior image quality
offered by your HDV camera, you can capture HDV material over the 1394
interface and edit the clips in SD on Matrox RT.X2. To do this, you create a
1440×1080i/p project and capture the HDV clips natively over the 1394
interface. You then create an SD project and import your HDV clips.
When working in your SD project you can capture native DV clips over the 1394
interface, and capture SD clips using Matrox RT.X2’s analog component,
S-Video, and composite inputs. The SD and HDV clips can be mixed in real time
in the same SD project. The HDV clips will be downscaled to SD when you scale
the clips to your project’s frame size for realtime playback as explained in
“Mixing SD and HD clips in a project” on page 20.
When your edits are complete, you can export your project to tape as SD video
for broadcast. If you want to deliver in HD format, you import your SD project to
a 1440×1080i/p project. You can then export to HD format without having to
recapture your clips (the SD clips can be upscaled to 1440×1080i/p format for
realtime playback).
This workflow scenario is represented in the following diagram:
