I am having a lot of trouble with my audio part of the video. It sounds fine in the previews, but when I actually create the movie, the sound gets all garbled and there is static. It is terrible.

I have some music as MP3 files that I import, and then I have created some live dialog. The videos I am making and testing are not very long, but I end up deleting them and starting over since the sound quality is terrible.

Does anyone have any suggestions or is this one for customer support? I have my latest .avi recording if anyone wants to hear it I can post it somewhere perhaps.

That's quite strange, is the video completely fine on the rendered output? It sounds like you've hit the 2gb avi limit. You could try shortening the section of the video you render or changing the quality down to see if that helps. Personally I'd stick with either mp4 or image sequence outputs since they're more reliable.

Yes: try to output it in mp4 format (max = 10.000 Kbps) to identify where the problem is.

If the issue is still there in the mp4-output the problem could be that your audio-input to Muvizu is not quite to the rendering codecs taste - and you might have i.e. to maybe lower the bit-rate.

Thank you both MrDrWho13 and ritsmer! I did just as you said in the quote area above and it worked great! This forum has helped me so much to save hours of work (that I would have deleted again). Now I am happy and can continue to make my whole video. I am sure I will need more help so please do not go away.

I see that this problem has been solved thanks to the diligence of helpful and knowledgeable forum gurus! Hats off to the good folks who help others here on a daily basis! You make this forum rock!

While we're on the topic of garbled sound, I'll add another thought that applies in different situations. Recording a signal too "hot" also introduces distortion. Sometimes it sounds OK when first recorded, but the more times it gets processed, it gets worse.

When recording audio in Audacity the VU meter will be either green or red, depending on the strength of the signal. If the VU meter ever turns red, that means the signal has "clipped" and the resulting audio will probably be distorted. The goal when recording is to watch the VU meter and adjust the recording volume until the signal is almost at the red point, but never red.

Most people here probably know that already, but since this is not primarily an audio forum, it's worth mentioning. Clipping is one of those perennial problems that tend to frustrate newcomers to the recording process.

What if you are recording on Audacity (which I have been using for years) and it is showing Red, but the play back shows Green? Will there still be problems?

Which is better to use for voice dialog recordings: Muvizu live or Audacity?

clipping occurs when you are recording the signal. Once you've recorded a clipped signal, even if you play it back at low volume (green VU) the signal is still of bad quality, and will tend to get worse the more you process it. So, the time when it is critical to keep the VU in the green is when you are recording the audio.

the best tool is the one you are most comfortable with. Both tools have advantages and disadvantages. The advantage of using Muvizus built-in dialog recorder is that you already have Muvizu open, and its integrated into the same program you're already using! That is very convenient! And for dialog it is probably the most convenient tool for the job.

Using Audacity on the other hand requires you to open a whole new program as you already know, which isn't convenient. However, Audacity is useful to me in the following ways:

1) If I have downloaded sound clips I can edit them easily in Audacity and make them exactly the size I need

2) Audacity easily lets me fade audio in and out, which is very useful

3) Because audacity can play multiple tracks, it is a great tool for staging the dialog between multiple characters. You can move the dialog left and right until the timing is perfect between the two dialogs... then when you send the two tracks to Muvizu, line up the beginning of each track and the timing will be right!

4)You can add effects like reverb in audacity, which can be useful if your character walks into a cave, or if you need to create spooky laughter

5) Audacity has all kinds of tools for cleaning up extraneous noise in sound clips.
and much more.

A basic comparison is that one is a recorder, while the other is a recorder AND an editor. They both record the same way. Sorry for the long reply. Feeling chatty today for some reason. Must be all that coffee...
