Using
your ViewCast Products in an Editing Environment
Both
Osprey Video and Niagara
streaming systems products can leverage the video and
audio editing capabilities found in popular editing packages
today, Adobe Premiere, Sonic Foundry Vegas Video, and Ulead
MediaStudio Pro. Given the extremely flexible nature of
Osprey products you can select what codec best applies to
your capture session. In some cases, you may desire to capture
uncompressed video in an .AVI format and in others you might
apply a codec like Cinepak. In either case Osprey Video
products are there supporting you.
What
about my DV inputs?
Certain Osprey Video products like those in the Osprey-500
and Osprey-540 series offer the ability to stream audio
and video inputs live from a DV input. Osprey Video cards
are designed with the intent of streaming audio and video
in a live scenario and have embraced techniques and methodologies
supporting this intent.
Many
users using DV inputs often think of DV in a native format,
commonly a 25Mbps format composed of I-frames. DV has evolved
into a great editing format given the quality, abundance
of reference frames allowing frame accurate editing, and
the association with OHCI offering device control.
The
key differentiation is that Osprey Video products DO allow
for capture from a DV input but do not capture native DV
to the host computer. Osprey Video products transcode the
captured DV source material in realtime from the compressed
native DV format to an uncompressed YUV format; this does
NOT prohibit editing though.
The
result is simply a different approach to editing from DV
inputs. Rather than providing the native DV format your
Osprey Video devices are providing the traditional uncompressed
to the host PC.
In
summary, what this means from an editing approach is that
if you are editing video captured from your Osprey Video
device's DV input you operate under a YUV format rather
than a native DV format for capturing the source material.
