Using the Matrox Offline HD codec
°To create your new offline HD editing project:
1 Open a new Adobe Premiere Pro project by choosing File > New, and from
the
Available Presets list, expand the Matrox - HD folder and select the
Offline
preset for the type of project you want to create.
¦NoteYou can’t capture to Matrox Offline HD format when working with a
1440×1080i/p project.
2 Select your capture settings as explained in “Defining your Capture settings”
on page 97.
3 Capture your clips using the Matrox Offline HD codec.
You can now work with the offline HD clips in the current project, or transfer the
clips to a remote Premiere Pro editing workstation. If you intend on completing
your offline HD project on a remote editing workstation, go to the next section. If
you intend on completing your offline HD editing project on Matrox Axio, go to
“Recapturing your clips at full HD resolution” on page 262.
Creating an offline HD project on a remote
editing workstation
As mentioned, the Matrox VFW Offline HD codec allows you to work with
low-resolution HD clips in Adobe Premiere Pro on a system that doesn’t have the
Matrox Axio hardware. You must, however, have the Matrox VFW software
codecs installed on this system (see “Installing the Matrox VFW software codecs
on a system without the Axio hardware” on page 56).
¦NoteIf you have a Matrox RT.X2 system, you can use it as a remote editing
workstation for your Matrox Axio offline HD projects instead of creating a VFW
project as explained in this section. For more information about this feature, see
your Matrox RT.X2 User Guide.
To create a VFW project that will allow you to use the offline HD clips that you
create on Matrox Axio, you must use the following project settings:
