[videoblogging] Re: avoiding/cleaning hum noise
Thanks everyone for advice. Yes, the hum sound is steady and it's through the whole filming (silent and voice), but it's just the level of volume of it that bothered me. I usually film 5-10 sec of quiet room ambient sound so that I can use it for cleaning the sound during editing, but this time it didn't help. I've been practicing a lot with the camera over these past days to try to figure out where the problem may be and I think that it's camera that makes this noise. I tried mic mounted on it, further from it-on a tripod..it still gave that hum sound. Even when the mic was off, I could still see the level of noise on my camera showing up. So I'm not sure if the jack is bad or if the camera is too loud in general. So I will probably end up leaving that background noise throughout the video. Now that I edited the clip, the sound doesn't seem so bad anymore. Maybe I just got used to it, I don't know :) But all the other versions of my sound cleaning just don't give me what I want-either the interviewee voice too thin, or the background noise not clean enough. Thanks again for your tips. I have a question about lavaliere. For interviews, is it better to use this type of mic.? Does it pick up less ambient sound. What about if I film outside with it..what noises does it pick up? If I filmed outside with a lavaliere and if it didn't pick up enough outside noise, maybe it wouldn't give the real sense of the environment? I don't know. Or is it enough to use the shot mic that I have and just mount it on a boom pole (any recommendations on which are good?) as close to the object as possible? Thanks again!

Lots of household/office appliances that we can't hear or filter out make a big hum when recorded - air con, computers, fridges, etc. Try being ruthless about shutting everything off when filming. Keep different types of cables away from each other, and if you need to cross them, do so at right angles. Test whether it's the tape mechanism that's making a lot of noise by monitoring the audio with a good pair of headphones at a distance from the camera, both with and without the tape running.

We use a wireless lavalier when we have time to hook it up to the person. It sounds awesome even in the noisiest of places. Plus it lets the person take us on walks without losing any sound. If we cant use a lavalier, we use a shotgun mic mounted to the camera. Whatever the camera points at, the sound is excellent. As always, just jump in. Experience will give you the answers.

Does it still make this sound outside away from all other equipment and wiring, and the mic mounted physically off and away from the camera? If it does then you have something seriously wrong with your setup. Experiment with your mic and camera gain perhaps? So I will probably end up leaving that background noise throughout the video.

Nothing special about a lavaliere mic, it's just a cheap electret mic insert. It works well simply because it is so close to the speaker, so voice level to background sound signal-to-noise ratio is much higher. i.e. voice is so loud you can turn the gain down, and the background sounds drop with it. A reasonably close shotgun mic should be just as good. Dave.

Could be all kinds of things. Youd be surprised how keenly sensitive this group will be if they can actually hear the hum.

[videoblogging] Re: avoiding/cleaning hum noise
Ruoert, I've filmed inside so far. But in this one particular location the hum sound is extremely big. I do have good earphones and I hear the sound in them as well. I haven't tried with the tape off, but I suspect that it's the camcorder mechanism in addition to the environment sound. I will try with the tape running and not. I usually don't use lots of cables. I just use charged battery and mic. Well this last time I did use a couple of lights. Maybe this could have added. I'll have to test that as well. However, now that I have this huge hum is there any way to fix it during editing (rerecording is not an option). I did try EQ and different noise removal programs that I mentioned in my first email-they all still leave that alien sound either in the background or on the voice. I'm frustrated and it's stopping me from moving forward. I was wondering if I don't use any noise removal programs, can I do smth with my editing software (Sony Vegas Platinum or Pro) at least to minimize the hum but leave the voice natural sounding?
