HVX Audio POPS during concert taping
I just shot some footage at a Blue Oyster Cult concert.
I just used the NAT MIC on the camera my audio levels were brought down pretty low and the audio level was okay.
Except, I kept on hearing audio pops in it...
the sound like your rice crispies cereal.. snap, crackel, pop...
I heard them as i was recording, I thought it was my headphones.
I just played it pack, and it's in the footage...
 
congratulations , you did distort the preamp stage
next time external mic with pre attunuation
 
Is there something i can do to the camera settings to use the Nat camera mic?
having and external mic is not an option....
 
Sorry, but... what do you mean by "nat camera mic"? Do you mean the built-in mic?

Also, was your camera somehow "disguised" so as to be hidden at the concert? If so, was there any material on/near the mic?
 
neumann dammy head.
put an ashes near by so if they ask the head is whith dead mean spirit inside ;-)
 
Yeah... I'm a little put off by the "external mic is not an option"... which is why this thread has turned into jokes from everybody.

This is as bad as a post which says "I shot my video in the dark... and I thought it was just my eyepiece that was making my footage look bad... then I got home and played it and the footage is dark."

"Get a light next time"

"using a light is not an option... can't I just set something in the camera to make it see in the dark?"

If the camera could handle the job of a competant and diverse audio system then a bunch of soundguys would be out of a job... and the audio forum probably wouldn't exist.

A concert is a demanding recording environment... if you refuse an external mic then the best you can do is get a line-feed off the board and run that into the cam... if you can't, or refuse, to do that... then I'd give up on recording concerts.

The one thing you CAN do is just get one of the farthest back seats in the house... sound is like light... inverse square law... so the dynamics of concert sound are progressively more demanding as you approach the stage.
 
This comment is kinda vaguely related to the topic. I have been working on the RPM Challenge, which is basically the musical equivalent of a timed film contest. Instead of 48 hours, or whatever you get a month to write and record a 10 song album. Anyhoo, they sent out a request for people to send them some video along with the album submissions, and I am of course, happily complying.

I'm trying to shoot a little BTS stuff every night when I record, and this weekend I hung the DVX100A up to record some drums. I have it mafer clamped to a C-Stand maybe a foot above the drummers (my) head. I haven't listened to the audio off camera yet, but it will be interesting to see if it can take it with just the onboard mics. I haven't brought in my SPL meter, but I'm pretty sure that I have never been to a show that was as loud as sitting about one meter away from my drum kit.


For the original poster, what you are describing does sound like distortion to me.

Guys, Can you just answer the question? If it is not possible then say so,
If you don't know how, don't say anything at all....
I came to this forum to get technical answers, not philosophy lectures on why i should or shouldn't do what I have to do.

I have done this in the past with my DVX, and when i had my IKEGAMI.
I just lowered the levels and audio was fine.
With the HVX, I lowered my levels and i got the popping sounds.
Is that because of the settings inside the camera?
should my "cam nat mic" have it's settings to -60 instead of -50???

When I say getting extra equipment is not an option, that is exactly what it is.
So I have to figure out a solution with what I have.
Don't waste my and others time with your stupid comments !

For the record: My client hired me to shoot an all day long event which included 2 concerts.
They wanted me to get several minutes of the concert and to be mobile. He did not want me to plug into the board for a clean feed.
He also wanted me in the front of the crowed to get my close up shots.
He then took my backstage to get footage.
After that he had me get on stage to get tight shots of the musicians while they were playing...
This was a run and gun style job that my client wanted.
AND HE DID NOT WANT TO PAY FOR AN EXTERNAL MIC AND AUDIO GUY!!!

I gave him what he paid for. unfortunatly the audio had the popping sounds.
Thank god he was okay the images and sound was not a big enough issue for this job.
For me, I want to prevent this again.

So, once again I ask.
With no external mic and audio guy and in a run and shoot situation.
Having manually lowered the levels on my previous cameras.
How can I get this done won my HVX??
 
no - philosophy , so here we go
you can glue the membranes stu.. if you cant bring cheap dynamic mic
 
I checked the BTS footage I shot about a foot away from my drum kit, and there was no distortion. It didn't sound particularly good. Admittedly it isn't an HVX, but I was able to make it work.

I'll be interested to see what quality of responses you receive after crapping all over everyone.
 
Dearest ajmax:

Perhaps you misunderstand.

An "external mic" can be clamped to your camera (the cam even comes with the clamp), and doesn't necessarily need a "sound guy."

If your problem is levels that are too high - then a cheapo low-output mic may just do the trick for you. Rummage through your basement, or garage sales, or go to Radio Shack with $9.95 for a crappy dynamic handheld and stick it on the camera.

Doesn't slow you down a bit! Run n gun all you want.

However, you're also not giving us much information, and not answering questiuons people have asked you here to clarify your problem, so they're gettin' a bit testy. Are your levels indeed too high? What do your level meters look like when your gain is turned all the way down? What do these pops sound like, how frequent are they, are they occurring when your audio levels are nowhere near peaking? Are you eating rice krispies while you shoot?
 
i turned my audio levels down because I was in front of the speaker.
That was fine. It's just when there was a hard beat, there was popping on top of the audio levels..
It does sound like rice krispies when you play it back.
My previous cameras were in the same situation and they never had that popping sound.
One of the cameras was the DVX the other was an Ikegami.
I asked earlier, could this be a setting in the camera menu that can be adjusted?
I know I have seen something like that before, I can't remember what it was.
I refer to an audio limiter that you can turn on and off

dont do any thing in analog domain , sits after ato d converters

Are you talking abouth the ALC? I'm 99.44% sure that's in the analog domain. What makes you think otherwise?
 
the dvx 100 its clips badly with very hot level even the limiter works
prevent brick walling not really feedback and reduce the input gain
didn't check with hvx , but nay think they did not change the agenda .
