Transitions cause noise

Post by LawnOrnament »

Has any one else had this problem?

I am using the trial version of VideoStudio and have been very pleased with how easy it is to use for a complete novice like myself. However, when I played back my first comleted DVD i discovered that there was a rather unpleasant hisk/click type of noise at every point where I had used a transition effect.

Any ideas anyone?

(Note that I'm a newbie, so can't give you a definitive answer, but...) Yes, I've seen/heard this (VS8). I think it's a consequence of the 2 clips overlapping when you use a transition between them.

It was most obvious at the *first* clip in the project that had audio included with the video (I was actually transitioning from a still image to video).

2 workarounds I came up with:
- use a long audio fade-in to get past the transition
- capture the audio to a separate file, and put it into the voice track,
then mute the audio level on the video (hope this makes sense :-)

The 2nd is more complicated, but gives better control and results.

I had this problem once and fixed it. I don't know if what I did had any relationship to the fix, but here goes:
I constructed a movie in Windows Movie Maker 2, and noticed the transition clicks. Then I redid it in VS7 and the clicks were gone.
Also, I noticed that my camcorder was set by default to record sound in 12 bit, at 32000 Khz. I adjusted the project properties in VS7 to 16 bit, 48000 Khz, and changed the settings in the camera - all audio is now captured at 16 bit, 48000 Khz.
So is Video Studio better than WMM2 (without doubt yes!) or was it the audio setting that did it?

I haven't had that problem, but I think rwindeyer may be onto something. All of my clips are MPEG with 48kHz stereo.

Make sure that all of your clips have the audio settings. The encoder may be having trouble switching between different source-formats. (?) I've noticed that audio doesn't "transition", it seems to switch suddenly at the end of the transition.

If the various clips have different audio formats, Try trimming the clips and saving as separate files with the same audio settings (Share Tab) before combining them together (with tansitions) in a new project. (In my case, this seemed to eliminate the infamous "lip sync" problem.)
