Workflow Scenarios
Understanding Typical Workflows
Using Io
LD
or Io
LA
and Final Cut Pro 4 allow more workflow flexibility than ever
before. Users can independently select different formats for capture and storage
media, while also outputting to analog and/or digital uncompressed formats.
Capture formats may vary, depending on the Io model you purchased. Media can
be stored on disk as:
•
offline quality at low bit rates
•
on-line quality at moderate bit rates
•
or with the highest quality as 8 or 10 bit uncompressed
Following are summaries of the most common workflows, listing data rates and
relative quality levels. Some workflows require a RAID array and some will work
using the host Power Mac’s internal system drive—it’s noted where this is
supported in the following discussions.
Corporate/Industrial
Io LA captures and outputs
component and composite video, with
4 channel balanced audio
Io LD captures and outputs
SDI video with embedded
audio.
Using standard desktop video
techniques, video/audio is captured
directly from a camcorder or deck.
Io
LD is used for playing back
captured media and editing/mastering
to tape or DVD using Final Cut 4 and
other tools
Monitoring a variety of legacy and
current devices for playback or
conversion can be a challenge. ,
AJA Io
LA can use all of its I/O ports
simultaneously, supporting a
wide range of old and new equipment
configurations.
