Analog audio is sampled at 48KHz 16 bits. DV audio can be output in analog at 32 KHz 12 bits, 44.1 kHz 16 bits or 48KHz 16bits. The DV-Bridge doesn't necessarily need a computer to work. It can convert to and from DV by itself and it is great to convert analog footage to be recorded on a DV camera or deck or DV footage from a camera or deck to be dubbed to any analog format. It automatically senses the input source and switches to the correct mode of operation. Because it converts in real time via hardware, it lets you watch your converted footage on the fly on an analog video monitor. When connected to a computer, depending on the software you can playback and/or edit your DV footage on the computer while watching it on a video monitor. This is definitely the way to edit as you can only see what a video will really look like on a video monitor. If you only use the computer monitor, you may end up finding out that what looks great on your Mac or PC screen may not necessarily look good on video.
I have read many messages on the Hollywood DV-Bridge technical support forums and I can see that most reported problems are actually a result of user error. This unit is extremely easy to use, still all the common rules of video do apply. As an example, many people complain about rolling images or loss of vertical sync. This seems to happen only when people feed non-timebase corrected VHS, Hi-8 or S-VHS video through the unit. In such cases the original signal may be bad enough to cause the DV-Bridge to lose reference, causing the aforementioned problems. The old "garbage in, garbage out" rule applies here and feeding good quality footage through the unit should definitely give you good results. If your footage is bad to start with, run it through a TBC before it goes into the DV-Bridge. Another common problem seems to be with the automatic mode switching function. It does take a few seconds to kick in and the more impatient users seem to have a hard time waiting for it to do so. I have found that, once in a while, the switch will not work but there's a little button in the back of the unit that lets you manually switch modes. I prefer to use the button all the time since it's faster, more reliable and it lets me switch between sources instantly.
The Dazzle Hollywood DV-Bridge is one of those rare products that deliver outstanding results at a very reasonable price. I consider it to be a must-have if you own a Mac or a PC with firewire connections and have at least one analog VTR or camera lying around. It is also a perfect unit for authoring DVDs on the Mac from Betacam SP or MII footage, since it will preserve the quality of the original images and should make your DVD footage look practically like your master. And since Apple's DVD Studio Pro relies on the DV format to achieve faster MPEG-2 compression, just the time saved on the first project should definitely make this a worthwhile purchase.
