Sound that gets quieter / more echo / muffled as camera moves away from it

[Chris Voelz]

Is the camera in after effects? Or are you referring to an actual camera that filmed the scene?

If after effects, you could make a separate audio track with your effects and link the distance to dB levels. So as the camera gets further away increase the levels of the sound effects, but that might cause other issues. It would be better to finish the video portion, export it, and do your audio mixing in a separate program like Audition or Audacity. You will get better results there and have more control.

sorry, i should have mentioned after effects camera

I would prefer to not have to do manual audio editing as there will be a lot of cuts in where the camera is far away, or close, etc. The camera will be moving a lot with lots of different distances.

But after reevaluating, i think i might have to. thanks for the response

You could use an expression for Audio Levels where the amplitude falls off as the inverse square of the distance from the camera increases. You’d need to define a nominal distance where at that distance or closer the falloff is 0 db. Something like this:

nominalDist = 2800;
C = thisComp.layer("Camera 1");
T = thisComp.layer("Target");
d = length(C.position - T.position);
if (d > nominalDist){
  n = Math.log2(d/nominalDist);
  value - ((value instanceof Array) ? [n,n]*6 : n*6);
}else{
  value;
}

Hey David,

Echo Dennis on online options.

Also, some manufacturers are now selling computers where there is only ethernet/wifi connection, or the ability to make USB ports / SD card readers unavailable, as these are potential threat to the system. Not only from hackers, but also “disgruntled” employees that wants to download data from the firm.

You may have a similar situation with some web-services, such as dropbox.

In short, you can’t win, except for having multiple options.Depending on length and subject matter:

PowerPoint will allow you to embed video.YouTube, unpublished, or Private view.OneDrive, Goog Drive and similar, is as good as DropBox for playing back MP4 videos in browser.Signiant, Hightail and WeTransfer can also work for transferring files.

You can also use platforms, mainly those hosting learning / courses, where you can charge for each view, or sell the download.

All of the above solutions comes down to how well you know your “consumer”, and what your business model is?
