DEVA POST PRODUCTION TIPS
The intention of this page is to give as much help as possible
to anyone that is wishing to load Deva generated files onto postproduction
equipment.
We intend to keep this page as up-to-date as possible and to that end,
would welcome any additional information or experiences you might wish
to share.

EDIT AND SYNCHING PACKAGES
Avid
The only versions of Avid software that will read Deva DVD files directly
is Avid Version 10.5 or later.
Your Avid will need a DVD RAM drive fitted to it's SCSI buss
The Avid will read BWF Poly files (16 or 24 bit width) from the DVD
RAM disk
We think you can make the Avid read MONO BWF files from the Deva DVD
RAM disk. There are implications within the Avid, as this means that if
you have more than one track recorded (there could, of course, be up to
four) it is not possible to associate the tracks greater than one together.
Therefore they will not all move at the same time within the time line.
Avid Software pre version 10.5 can read Deva DVD discs, but you will
need DVD-RAM Tune Up (www.softarch.com)
and DOS Mounter v3.05 (www.softarch.com).
Devalink (www.syence.co.uk)
will be needed for Mac based machines, and AV Transfer (www.avtransfer.com)
if your machine is a Windows NT version Avid.
There is an implication in having BWF Poly files delivered to the editor
for synching up. Many post production machines do NOT support BWF Poly
as an import format, so you need to give thought here to the autoconform
and track lay.
Pro Tools
Pro Tools is becoming more popular in the UK. The latest versions will
now read BWF file but older versions will only read SDII files.
Importing into Pro Tools necessitates Dos Mounter 3.05, no other version
of this programme will read Deva formatted DVD discs.
DVD Ram Tune Up is also required.
INDAW
Aaton Indaw 6 (which works only in Windows NT) can read Deva produced
DVD RAM disks directly.
If your job is being synched up with Indaw then be aware that Indaw can
read both BWF Mono and BWF Poly files, but that BWF mono files are NOT
compatible with the keylink system.
At present Indaw likes to see TOD TC with breaks in the TC between shots
- this is how Indaw distinguishes between the end of one shot and the
start of the next.

DAR
DAR (now defunct!) reads AES 31 files, so it should be possible to get
BWF files into DAR if required.
Fostex DV40
With the introduction of this new machine from Fostex, utilising Deva
produced DVD Ram disks has finally become transparent.
The DV40 is a direct replacement for a DAT machine in the post production
process. It can playback files from DVD Ram disks either as 4 tracks of
digital (or analogue) audio, or file transfers via Ethernet connections.
This machine can be controlled by a standard RS422 interface and plays
back both FAT16 and UDF formatted files. Files can be linked in PB mode
so that the whole disk will chase incoming TC, for instance, from video
and lock up with full sync almost instantly.
Ideal for batch digitising into Avid editors or as a stand alone file
transfer machine for Sadie or Protools audio work stations.

Devalink
Devalink is a software solution that allows automatic transfer of audio
and TC information from Deva recorded DVD RAM disks into Avid Media Composers.
It reads SD2 files from DVD RAM media and creates OMF 1 or 2 sessions
from them, which can then be loaded into Avid. It is designed to run on
any Macintosh computer with a Power PC processor.

DRIVES
Firewire DVD Ram drives
Recent experience has shown that Firewire DVD Ram drives on a Mac based
Pro Tools system can be problematic. The computer will format and write
to and read from the drive. Unfortunately Deva formatted discs cannot
be read from this DVD Ram drive. Changing to a SCSI drive solves the problem.
