Working with HD material

Matrox Axio provides Premiere Pro sequence presets for many of the common
HD video formats, and several Matrox HD video codecs that allow you to capture
and export your video at different video qualities. You can capture your footage
using the appropriate codec for the source material and then combine the footage
as needed. For example, you can mix MPEG-2 I-frame HD, DVCPRO HD, and
uncompressed HD clips in the same sequence. For more information about
working with Matrox codecs in your HD sequences, see the next section,
the Matrox HD
In some cases, Matrox Axio applies a pulldown method so that you can capture
an HD video format (input format) that is different from the HD format that's
defined by your sequence settings. For example, to capture 1080i @ 29.97 fps
source video for use in a 1080p @ 23.98 fps sequence, Axio will perform a
standard reverse pulldown on your input video during capture. For more
information about how pulldown can be applied in your HD sequence, see
"Applying pulldown in HD sequences"

About the Matrox HD codecs

When creating an HD video sequence, there are a number of editing decisions
that must be made, including the selection of an appropriate HD video codec.
Your Matrox Axio system provides you with different HD video codecs to
perform offline edits and finishing-quality online edits. The following provides a
summary of some Matrox HD video codecs and their most suitable uses:
• Matrox MPEG-2 I-frame HD codec
MPEG-2 I-frame HD format that produces high-quality, low bit-rate video
that can be used for either online or offline editing. The Matrox VFW
MPEG-2 I-frame HD codec allows you to render material to full HD video
using VFW applications, such as Adobe After Effects. For examples of
workflows that use the Matrox MPEG-2 I-frame HD codec, see
Matrox MPEG-2 I-frame HD codec for online editing"
"Using the Matrox MPEG-2 I-frame HD codec for offline editing"
page 200.
• Matrox 8-bit and 10-bit Uncompressed HD codecs
video to full-resolution, finishing-quality HD video for online editing. The
Matrox VFW Uncompressed HD codecs allow you to render material to
full-resolution, finishing-quality HD video for use with Matrox Axio using
VFW applications, such as Adobe After Effects. For an example of a
workflow that uses the Matrox 8-bit or 10-bit Uncompressed HD codec, see
"Using the Matrox 8-bit and 10-bit Uncompressed HD codecs"
• Matrox DVCPRO HD codec
full-resolution, finishing-quality DVCPRO HD format for online editing.
