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.
