Getting Audio via Firewire to Broadcast Monitor
I’m feeding audio and video via firewire into my mini dv deck.
S-Video out and stereo RCA’s out to my Sony broadcast monitor.Mini DV deck is just on – no tape armed, don’t know how to do this
other than “Print to Video” layback function, which I don’t need.I’m getting picture fine.
Just need to hear the sync’d sound with picture while I edit.In FCPro 4.5 HD my setting are as follows:
VIEW/Playhead Sync/Follow
VIEW/External Video/All Frames
VIEW/Video Playback/Apple Firewire NTSC
VIEW/Audio Playback/Firewire DV checked and grey’d out/Audio follows VideoUnder Pref’s
Audio-Video Settings/Device Control Preset -Firewire NTSC NDF
Audio-Video Settings/Video Playback/Apple Firewire NTSC
Audio-Video Setting/Audio Playback/Firewire DVCPU Pref’s
Sound/Output – no firewire option
options are: Built In Audio (CPU spkrs)
Digital Audio (Optical Digital Out port)
Logitech USB Headset
SoundsticksWhen I use the Soundsticks (main monitor rig) there’s a delay
(USB) between visual on the broadcast monitor.How do I get the sound directed to the broadcast monitor speakers?
Setting??????Help.

Any audio going out via the firewire will experience a delay (3-7 frames usually) relative to the computer monitor. THe only way around this is to use a video CARD that lives inside the computer, like a AJA or Blackmagic. These cards use the pci bus, and therefore can output video in sync with the timeline.
Your settings seem to be correct: firewire out for both picture and sound. Can you confirm that audio is getting to the DV deck? Does that deck have headphones? VU meters? If it’s getting to the deck, then your problem is downstream from there. If it’s not getting to the deck, then try trashing your preference, restarting everything and trying again.

Audio is going to the deck, right?
You should hook up some kind of audio monitors to the deck’s analog outputs. Anything from headphones to computer speakers to actual nice speakers.
At that point the video on your external monitor and the audio from those monitors should match. You are watching and listening to the video and audio coming out of the deck’s analog ports.
Ok, great. But the comptuer screen is probably off, right?
At that point, go into System Settings > Playback control and find the box for “Frame Offset.”
Set it at 4 to start and see if everything matches up. If not, mess around with the number ’till you find what works.

Thnx gents.
Unless I arm the DV deck, there’s no way to see levels of audio going in.
I think the problem is going firewire digital to analog into the monitor
creates latency.I’m using my regular speakers using the System settings/Playback Control/
Frame Offset @ 30. It won’t go any higher, but it’s close enough.
For finite tweaking, I can set it back to original settings and dial in
using the cpu display.Much appreciated.
