Using the Matrox MPEG-2 I-frame HD codec
MPEG-2 I-frame HD codec workflow example
for online editing
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.
