Annoying Click/Pop in the audio at end of a .MOV export

Hi,

I've had this problem on two different PCs with AS5 so I don't know what I'm doing wrong. I'm going to upgrade to 6 after this project but I don't know if that'll fix it.

I export as .mov, Animation, Millions of Colors and when I play back the video theres always a little popping/click noise at the end of the files. Which is obviously annoying when I try to edit the videos together.

Anyone else get this? Is there a fix?

Thanks

P.S. I'm on Vista (Soon to be Windows 7!)

Hmm...what audio file are you using? And at what KHz is it recorded at? Maybe try a stereo 44,000 Khz file (I think that's right) .WAV or .MP3 and see if that makes a difference. Could be something about your audio file, where its recorded at too high or too low a resolution or something else.

You need to tweak your audio files in an audio editor like Audacity.

Select the last few milliseconds of the sound file and apply "fade out". This ensures that the last samples of the file are really at zero level, and cannot cause any popping.

Of course this doesn't work for snippets out of a continuous sound, like a song. In that case you make snippets for animating to, but don't export them with the animation. Instead you import the music as a whole into your video editor and arrange the video clips to that.

I don't export any soundtrack with my animation, instead I do all the syncing in my video editor, especially because it has much more abilities to mix and filter and whatnot.

Thanks for the replies

I'm fairly certain they are saved as stereo 44,000 Khz wav files but I will double check when I get home. I use Wavepad Audio editor.

I'll try the fade out idea too to get them totally silent. When I play the wav files I definitely can't hear anything but maybe that'll do it.

It doesn't stop me working, just really annoying and I wondered if I was alone with the problem! Thanks
