Audio "click" at start

Sometimes I get an audio "click" at the very beginning of a video no matter where I edit & create the starting point. Even though the audio level looks like it is silent, there must be just enough in the lead in to create a click or pop sound when the video starts.

Is there any way to silence or attenuate this?

The click is on the computer when I preview the output (project) file. On some TV recordings it seems no matter where I cut in order to delete the preceding commercials that there is a click. It's not loud, just irritating that it's there.

This sort of thing used to bother me when I worked on a too-slow computer for the video I was editing.
(so, over time, my computer became less acceptable as the video resolution increased)
Anyway, it was only an artifact on the computer and not in the output file.
You might see if it shows up in your output, and ignore it as I did. ;)
...or... get a hotter computer, faster video card, etc...
(actually, I did both)

Nothing VideoReDO is doing would cause a click. It simply cuts the audio stream on the frame bounds closest to the video frame. If we need to insert a frame to maintain sync we insert a completely silent frame.

Like Anole suggested make sure this artifact actually happens in the output. It could just be a glitch in the preview and not actually effect the output video.

Your right, after authoring the click is not there.

I'm using a quad core AMD computer which I bought earlier this year so it should be fast enough. It really moves along compared to my old single core P4.

I just cut off the preceding commercial on another recording and there was no click in the initial project, which is the usual scenario. In both of these cases the blue audio level line was all the way down to the minimum level. I don’t know why one has a click and not the other, but I’m glad it does not show up in the final product.

Thanks for the tip.

By default we use DirectSound for audio output. It could be there is some bug in your audio driver that is causing the click. If you go to Tools->Options->Playback devices you can try using one of the other audio options to see if maybe it eliminates the problem for you.

I tried the other 2 available options but they did not make any difference. As long as the click is not in the final authored version it's OK.
