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 offline HD, MPEG-2 I-frame HD, HDV,
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,
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 Offline HD codec
format to create offline edits that use less disk space. A Video for Windows
(VFW) version of the offline HD codec is available for use with VFW
applications. When this codec is installed on a system without Matrox Axio
hardware, such as a laptop computer, the system can be used to complete
offline editing projects in Adobe Premiere Pro. For some examples of
workflows that use the Matrox Offline HD codec, see
Offline HD codec"
• 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 offline or online 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. On a system without
the Matrox Axio hardware, this codec can be used to render and play back
1440 ×1080i/p clips only. For examples of workflows that use the Matrox
MPEG-2 I-frame HD codec, see
