VIDEO FIREWIRE DEVICES

These are all similar in functionality with Analog Video/Audio I/O converting to and from DV format via Firewire.

Note: using a DV Codec box introduces a 300mSec hardware latency, and although this is sync orrected perfectly during record/playback, scrub and jogging with a DV device is typically less responsive than with a PCI card. However the high picture quality and convenience of DV codecs offer a non-PCI solution which is ideal for many applications.
Virtual VTR is designed to work with QuickTime compatible video hardware. Most often this means PCI cards which capture and playback video, using standard, or proprietary codecs. Alternatively, you can use any QuickTime Software codec, although this may limit the quality of the picture you are able to deal with in real time.

The other important category is Firewire based DV or uncompressed video. VirtualVTR is able to deliver a QuickTime data stream through a Firewire connection to be fed to a transcoder box which turns that into analog video. Most of these boxes use the DV format, but some offer other feeds too, for example AJA ioHD.

VIDEO PCI CARDS

AJA:
Kona - Highly Recommended for Professional and Broadcast applications. VirtualVTR Pro has special modes for tighter integration with Kona, ioXT and io4K.

BlackMagic Designs:
DeckLink cards can often be used with VirtualVTR in a basic mode, although some versions of the BlackMagic driver have problems with chase-sync type operations

THUNDERBOLT VIDEO DEVICES
The recommended interface for VirtualVTR is AJA ioXT or AJA io4K. For non chase-sync applications, most BlackMagic products will work, although not for 4K. Contact your Gallery dealers for the latest information about synchronising with these devices.

SYNCHRONISATION & CONNECTIVITY HARDWARE

TIMECODE GENERATORS / READER - CB P2MMC
The P2MMC interface is a general problem solver for complex and advanced VVTR setups. It acts as a timecode reader/generator, P2 / MMC interface, and supports special modes in the VirtualVTR software.

MIDI INTERFACES
If you use VirtualVTR slaving to or generating timecode, or under MMC control, you will need an MIDI interface.
Officially Supported Device :
M-Audio Midisport 2x2


SERIAL PORTS / CABLES FOR 9 PIN
If you use VirtualVTR with 9-pin control, you will need a free serial port and the appropriate Cross over slave cable. The Serial ports on AJA Kona cards work well (with the slave cable). Also Keyspan USA28X (with slave cable). Also CBElectronics USB 422 offers 9-pin serial via USB with jumper select, so no slave cable needed. USB 422 also has LEDs which make troubleshooting easier.
