How do you get that fresh sound with your skate clips? for example. If someones doing a line, the rolling sounds pretty low but the pop and grind and when the skater rolls over cracks in the concrete it sounds nice n loud.
I really dont think they keyframe each single pop, grind and land. Is there some sort of filter?

yeah i noticed in PJ Ladds part in really sorry.
no matter how far away from the camera he is the audio never differs.
like ull hear it pop at the top of a stair set and the landings the same even though he land right next to the camera.

its called compression and noise gates bruz.....

tell me more!

ahh its pretty hard to explain fully without being able to demonstrate shit.

a compressor:
just say you have a piece of audio that spans a dynamic range of 50dB (decibel), some stuff nice and loud, but some stuff is too quiet. just say you want the audio to only span 25dB. Then you would set the threshold of the compressor to whatever the lowest point of sound you would want and a ratio of 2:1.
This means that the range of 50dB would be compressed into 25dB, making everything closer to the same amplitude (volume basically).

You can use noise gates to only let audio through when the amplitude gets above a certain point. Otherwise they let nothing through...

Pretty vague explanations but as i said, its reasonably complex and im tired.

ohhhhhhh, nice explanation nate thats so sick
can you do it just in a video editing program like premiere?

Nate Dawg 14:20 08/Aug/05

not real sure mate. dont have a cam myself so i havent got around to playing with it much.

probably some plugins you can use at the very least though!

mers 01:10 09/Aug/05

do you produce music at all nate dawg? compression isnt really something alot of video heads would know about

Nate Dawg 01:14 09/Aug/05

ah im just an amatuer.....recorded half a split EP for a band and just did some other shit at college. its fun.

id never really thought too much about the audio side of skate vids either to tell you the truth...

lorenz 08:18 09/Aug/05

directional mics (such as shotgun mics) are used to pik up the sound well, compared to the little mic u have on ure cheap camera that will pik up all sounds around it, and with fairly poor quality

wow my muici teacher was talking about gates or whatever today and now im reading bout them weird

chris_decay 21:10 09/Aug/05

some gates also have a thing called range, which allows you to bring the noise floor up a bit, while still opening up fully when the threshold gets hit.

yeh i also found extracting the audio off the video into Nuendo, then using the compressors and gates in their, little eq, then u can just automate any volume change u want, and if ur camera has a mono mic then u can do some panning so it sounds like the board rolls from left to right or whatever. thats the way i do it but no one has ever shown me how, tho i know a lil bit about audio, i just figured this way works for me

so i dunno if premier has this sorta thing but if it does, do it, if not maybe try and get an audio editing suite, Nuendo is sick for multimedia and u could find a crack of V2 on the net somewhere

Nate Dawg 04:01 10/Aug/05

yeah i use nuendo because its alot easier to get a cracked version than pro-tools.

i never did it in nuendo, but in pro-tools you can physically draw the volume changes in for any track of audio. like a graph type thing.

cheese-wagon 07:13 10/Aug/05

yeh same old shit in nuendo to draw in automation curves. and the cracked versions u can find r pretty good, not too much dodgy shit in my version, i have v.2
