Using the Matrox MPEG-2 I-frame HD codec
MPEG-2 I-frame HD codec workflow example
for online editing
In this workflow example, the Matrox MPEG-2 I-frame HD codec is used to
capture video clips for use in an online editing project. The clips are captured
with Matrox RT.X2 at a data rate of 90 Mb/sec or higher and then used to
complete an online editing project. A VFW application, such as Adobe After
Effects, is used to create a composition that is rendered using the VFW MPEG-2
I-frame HD codec and imported into the online editing project. When the edit is
complete, it is exported to tape for broadcast.
This workflow scenario is represented in the following diagram:
