● Video Drives: Avid rS drives, iS Pro drives, iS Plus drives or DigiDrives. At this time,

the Avid MediaDock is not officially qualified for use with AVoption.

● About Firewire Drives: The DigiDrive FireWire 80 (as well as other firewire drives) are

not qualified for use with AVoption or AVoption|XL. AVoption and AVoption|XL require

SCSI storage for recording and playback. However, you can use the DigiDrive FireWire

80 to back-up your video storage SCSI drives.

Third Party Video Capture Cards: The Pinnacle miroMotion DC30 Plus QuickTime capture card

(with firmware v1.2.1) is not officially qualified for use with AVoption, but it does appear to

coexist with the ABVB/Janus cards in Digidesign's limited investigations. Your results may vary

from these findings. Software for the miroMotion DC30 Plus can be found in the Digidesign

Support/Downloads/Utilities section of the website.

Dual Screen Monitor Cards: Currently, the only Dual Screen Monitor Card qualified for use

with AVoption is the Appian Jeronimo 2000 AGP for Macintosh. This is a single AGP card which

can drive two VGA monitors. This card is currently qualified only for use with single-processor

G4 computers with AGP graphics systems. The PCI version of this card is not supported.

For more information see the Appian page in the Digidesign Support / Downloads section

Maximum Performance Guidelines

Compatible Dual-Channel SCSI HBA card

Total System RAM: Minimum 256 MB

Note: AVoption supports "plug and play" compatibility with many Avid systems. When

"inheriting" a drive containing audio and video data from an Avid system, we recommend you

connect this drive to the SCSI channel dedicated to video storage. There is no need to copy the

audio data from such a drive to your dedicated audio drives, however we recommend that you

not record any additional audio tracks onto this drive.

Virtually all the testing for AVoption was done with a baseline of 32 tracks of 24- bit/48k audio

and one stream of AVR77 video data (record and/or playback). These test configurations

generally included one drive for every 16 tracks of audio. One way to achieve higher track

counts is to dedicate more drives to the audio tracks.

On a supported configuration, you should be able to easily achieve this performance baseline,

even with a high degree of edit density on each track. The higher the edit density, the more

heavily taxed will be the storage subsystem.

You may find much better results than this baseline, since Digidesign's performance tests re

designed to stress the storage subsystem more heavily than the average "real world" usage. In

several cases, our test group was able to continuous record or playback of 64 audio tracks and

AVR77 picture simultaneously.

There are other possible steps that can be taken to maximize the performance of a Pro Tools

system with AVoption consult the User Guide or Release Bulletin (available for download as a PDF

here)
