  • Firewire card recommendation and audio sync question

    Hi all. I have been visiting this forum for a couple of years, but this is only my 2nd post. (this is a great resource btw)

    I am thinking of getting a Firewire card to go with my Sony TRV510 camera and am looking for suggestions. My needs are very modest - capturing clips to put on my web site, editing commercials out of TV programs, and maybe finishing my cousins wedding video from 3 years ago ).
    I had (still have actually) a Marvel G200, but moved on to a Millenium G400 and lost the video capture capability. I don't need a tuner or analog input particularly, but if the TRV510 can be convinced to do real time conversion of analog to DV for capture via Firewire, then so much the better.
    I see that the ADS Pyro seems to get favorable comments here, so I'm leaning in that direction, but I do have one question about Firewire first:
    Is the audio transferred along with the video, or do you need to connect analog audio to your soundcard and record it that way? One thing I definitely can't stand is A/V sync problems, but if the audio is sent in digital form along with the video, maybe that isn't a problem (hopefully)??

    I am a semi-hardcore hardware/software geek, so I have no fear of card or driver setup issues and my machine is pretty standard fare anyway: PII400 on ASUS P2B, 128M, SBLive!, Intel ethernet, G400, standard IDE hard/optical drives, WindowsME.

    Thanks for any suggestions!

    Brad.

    Firewire carries both the video and audio signals. However, A/V sync problems can still occur from what I've read here. There's never a simple answer...

      Firewire tranfers one stream of mixed audio and video. If you play that avi on computer with software codec, you can get audio out of sync, because your sound card is in use. If you don't try to compensate such mismatch and transfer avi back to tape, you should get perfect sync.
      I do so with DV raptor and with Dazzle PCMCIA firewire card for my notebook. Dazzle also has pci version for desktops.
