Help! Audio click / artifact in rendered project
Running Vegas 6 w/ all updates. I recently installed Vegas 7+DVD upgrade with all updates but I am not using yet due to a missing serial number ( an interesting story but unimportant to this post). Since installing Vegas 7 on my machine (Athlon 64×2 4400, 2 gb RAM, Win XP) I have an annoying “click” almost like a metronome sound that appears when rendering to MPEG2. (The preview in Vegas plays perfect.) It is just a single audible “Click” that occurs about 1.5 secs into the finished video, although there is no video artifacting.
This is the first significant problem I have had with Vegas. I have tried several experiments or work-arounds and nothing seems to work. (some of the things I have tried are: rendering the project’s veg file in a different project; trimming the first 2 seconds off the project; sliding the project to the right and rendering only the loop region; deleting the title and renfering; trimming the beginning of the audio files in the intro to make sure they aren’t corrupted (they aren’t)).
This is happening to me not in just one project but in multiple projects, although I did make a test project consisting of a single video/audio clip and it worked fine. I have seen some reference to problems with the alpha channel in 7.0c but its weird that it might affect my existing installation of Vegas 6.
Any help would be greatly appreciated!

If it’s a repeated click like a metronome, that IS important, because it indicates that you are running in trial mode.
If it’s a single click, zoom way in and see if there’s something amiss with your audio, especially a leftover bit that’s on a separate track or even on the same track.

Hi Gary – thanks for the quick response – on New Year’s day yet!
I solved the problem but the whole episode is still quite puzzling. As I said earlier, previews plays fine within Vegas so I concluded that the problem was in the encoding of the MPEG file. I had been using a custom template I created that started with the default template and just made it best quality with 2-pass encoding. It had worked great until recently. I tried the basic default template, no problem. I then recreated my 2-pass template, no problem!
I can only conclude that somehow my custom preset file became corrupted. Hopefully if anyone else has this problem occir this will make it easier for them to trace it.
I started with Vegas about a year ago – I made the change with some encouragement from folks on this board and I am glad I did.
Thanks again.

You should probably be encoding the audio to a separate AC3 file unless you have a special reason not to.

I always make 3 files – an MPEG with audio, a video file and a separate AC-3 file. My problem of course was with the combined file. I like to have a combined file in order to play it in Windows Media Player, etc.
BTW, for the video stream I use the DVD architect default parameters. Is it better to use the 2-pass encoding with that setting?
Thanks again,
