audio popping, loud static, cycles over and over...

I received several miniDV tapes to do some editing for a friend.

When I captured (using a consumer camcorder), there was alot of static and pops. I played the tapes in my DVX, and it still had the distortions.

On the Vegas timeline, the bursts of static noise 'cycles,' by which I mean it often repeats every minute or so through much of the tape(s). Each burst last a few seconds, and seems to be primarliy on the "near side" mic line, though not sure on that. Using envelopes to change channels to the 'far side' doesn't completely eliminate the static sounds.

There is also an occasional distortion to the speaker's voice, almost making him sound 'robotic' due to a 'metalic' quality to the sound.

So... Bursts of static, electical pops, metalic voice...

What do you think? Anyone else had this?

I hope I can try to use SoundForge to try and eliminate some of the static sounds, but the metalic voice and pops?
 
Could be a lot of different things. Was the "near side" mic a wireless or were they both wireless? Metallic voice suggests brickwalling to me.

Need more info on how it was recorded...and a sample would help.

Cheers

Anyhow, when I referred to 'near side' and 'far side' channels, I was meaning how (on the DVX) the mic only plugs into one audio jack, and being on the actor (assuming its on a boom or lapel or something near them), serves as the 'far side' (from the camera) whereas the onboard mic serves as the 'near side' to the camera, though far from the actor. Thus, one often gets 2 different qualities of sound; one near the actor, the other far (mounted right on the camera itself). This is a ridiculous, convoluted and confusing description, and probably has no bearing on this problem anyhow, LOL! (I'm not even sure the footage was even shot on a DVX!)

I tried to do a rudimentary fix on SoundForge, but it didn't make much difference. Seems like I'm screwed, stuck with this audio, unless there's another option.
 
it sounds more as electronic problem during the capturing , bad cable or other problem inside the camera , not overloading or brick walling , dont think you really can do anything about except adr the sequence .
probably better check the camera was involved as it seems has some problem in front of the ato d converter
 
EEk. That is some nasty stuff you got there. You seem to have a bit of everything including brickwalling. The worst of it does sound like some hardware is malfunctioning as Oleg said but I am not familar with anything that sounds like that.

There is not a lot to do to salvage that mess, sorry. I would be curious to hear how that was recorded.

That clip will haunt my nightmares now.

Good luck
 
yeah, I'm screwed...

yeah, I'm screwed...

The way it works, a friend of mine has a 'professional' film his stuff, then mails me (copies of) the tapes to do all the post work on, output to DVD.

Anyhow, I think the static/interfearance was recorded when the guy made copies of his originals. Long story, but there are places where the same footage is recorded twice (runs out at the end of one tape, so he rewinds to the beginning of the take, then starts on another blank tape.) Anyhow, the static only occured on 1 of the exact same takes!

That tells me either the tapes are bad, or something in his 'copying' system was screwed up, but the original footage did not have the static (since it only occured once in two identical footage takes).
 
The recording was also extremely clipped. Were the originals clipped? I assume he did not clone the tapes but went through an d/a a/d stage? Next time ask him to clone the tapes.

Cheers
 
Hi,

playback the tape in the camera it has been recorded in and check if the noise is still there. There are known issues if Canon recorded tapes are being played back in a Sony camera according to the sound (are the beeps part of the recording or part of the noise?)

regards,
mm
