Using a laptop for audio,sync issues

[oldasdirt]

Been looking around at interfaces and software to make my laptop a replacement for my Nagra.Now here's another issue.Doesn't really have to be an issue,I suppose I could live without it if I wanted to spend alot of time in post,which I don't,so I want to look into doing digital sync.

I shoot with a Canon 814 AZ which has a sync port.Just wondering if I can run a line out of that into my 4 channel Sure mixer which has a tone generator.Hopefully the camera pulse can interupt the tone so that I have 1 F spike corresponding to each frame.This should make it easier to sync should it not?Anyone ever try anything like this,or do you all just go crystal or wild?

I'm really not into long post looping/dubbing sessions and alot of the stuff I shoot is documentary style.

I need more information.

If your mixer had no tone generator, would you feel you were at some disadvantage?

My understanding of the way 1 F (digital) sync works is that the signal coming from the camera needs an amplified tone to interrupt with pulses per frame.Am I wrong?

[Alex]

This is out of my area of knowledge but wouldn't the camera make enough of a pulse that your digital device could read it whether or not it had it's own tone being generated?

I'm not sure,Alex,that's why I'm posting.I thought the pulse just closed a circuit,therefore it needed a tone or burst to be recorded.
