Recording DV video and soundcard audio at the same time

guitardog247


I want to do this, I'll try to explain:
 
I have a video camera set up to record directly to the PC, via firewire.
And Sony home studio splits the Audio and video up separate. Okay.
But it only uses the audio from the cam mic. I can't select another audio source.
 
How can this be achieved, if anyone knows?
 
I want to capture simultaneously, my video, and the audio from my mixer and emu 0404 PCI sound card.
 
 
 

I don't think so. Just import the audio into the project after you aquire the video, that's how it's expected to be done.  Does your Sony version let you do that ?  You should be able to move the audio around and get it right in the spot you want.  Don't feel bad, the big version of Vegas can't do it either.  Video capture of a firewire streem done by a seperate program and that's all it does.
 
Tip: If you plan to record audio on another device while you are making the video make sure you record at the same sample rate as the soundtrack on the camcorder.  It syncs up a lot better that way.  For example my camcorder records at 48K so I use that sample rate when recording audio for the show.

Yes, it can of course use an imported audio of your choosing. But I want something "live".

There has to be a way. I watch a girl on Youtube, she uses her studio condenser mic, so it's good audio. She even does muliti tracks of video in the corner, plays along with herself! I don't need that, just want the soundcard audio instead of my cam mic.

There are no programs I know of that can do that.  Video editing software is "layout" software. You are expected to have all your parts aquired in advance, import them all and position them on the timeline.  It's not like audio multitrack where you can record everything in one shot.  Folks who have only done audio get frustrated about this but that's just the way the video world works.
 
Here are some ideas. 1. Use another program to record the audio.  2. If the camcorder has a line level input connect your audio source to it.  3. Use a hardware recorder for the audio like a Zoom or Tascam handheld. 
 
More tips: 1. Remember to use the same sample rate on all audio recordings. 2. Make a sharp noise that both systems record before you start so you have an alignment spike in the waves to help you get it close.  3. Never stop and restart the camcorder or audio recorder just let it roll. That way you only have to line it up once before you start cuting. If you stop and start it's going to be a mess and a lot more work. 4. Try to use two camcorders if you can so you can have two tracks of video to choose from.  It's best if they are the same model with the same settings. 5. Let the camcorder record audio and aquire it even if you don't plan to use it in the final product. You will need that to help line up the other audio to match the video. The spikes in the wave are perfect reference points.

I guess Virtualdub is the answer to my dilemna.

After much googling. I found Virtualdub, whch I swear I've heard of before. I guess this allows a different audio source, although as you mentioned it should be sample rate.

I haven't tried it yet. Chose to sleep last night.

Actually, duh, a video capture card. I can plug my mixer-out into the audio in, instead of the cam output. Cheaper than buying a new cam anyway.

You are going to lose quality that way, the video has to be converted, twice ! just to get into the computer. Not only that but the audio quality of those capture cards are not great. Most are 16bit only.  The only way to get full quality and stay in digital all the way is with firewire.
