Breake in a dialogue

[jimmyy]

I have a dialogue where two people talk too fast. I did slow motion in Sony Vegas and now I would like to add 0, 5-1 sec of silence in between the words.

I'm doing the following:
splitting the movie and the audio
taking a snapshot of the last frame of the first split segment
and then I would add that picture of the snapshot on the video frame and repeat it for 2seconds
then I would split the second segment one more time where there is only noise and nobody talks
I would then copy the audio with the noise on the timeframe under the snapshot taken before

but if I do the above and play, the image is fine, but at the end of segment one you could hear a click between the audio of segment 1 and the noise that I've copied, it's not continuous the sound.

What do you think, what am I doing wrong, or what should I do better.

You're doing it right, you just need to finesse it a little.

The simplest fix is to add a quick dissolve where you hear the click. In Vegas this is easy, you just drag the clips to overlap a few frames (audio only, of course.)

If that doesn't work you may need to loop (copy and repeat) and blend your presence (noise) on another track. You may need to adjust levels and timing to make it seamless.

Sometimes adding a sound effect such as a car horn in the distance can mask the cut.

This is standard audio editor stuff.

Professional crews will frequently record :30 or so of "room tone" at every location precisely for this purpose.

Thank you very much for your response.
What do you mean by loop and repeat? To copy the noise and then repeat it to fill in my gap?

What I find strange is that I'm doing the same editing in audacity and I do not have any problem, no glitch in between. But it's very complicated to edit audio in audacity and then resynchronize it back in Vegas.

I'll try your advises thank you very much

A "Loop" is a short clip that repeats seamlessly. Like a bird flying, or a drum pattern. Trance music is another example.

You can do all your audio editing right in Vegas. One of the best features of Vegas is that a "Project File", or .VEG, can be an elemental.

You can build all your elementals without ever rendering anything until the final.

Check both sides of the edit.

If you zoom way in on the waveform in Vegas you will probably find a mismatched sample edge at the cut causing the click. That's what needs to be smoothed out.

To stay in sync with the picture, Vegas cuts, at least initially, to the frame 1/25 or 1/30 sec. Audacity cuts to the sample 1/48000 sec.

Hi,

I think that I made it work!!! thanks to your advises.

I overlapped a bit the noise with the other segments and then I increased the Fade in offset only for the noise and deleted the fade out/in for the other(than noise) segments.

Thank you very much

[smrpix]

Nice going. Glad it worked out for you.

Yes, you get clicks when there is a discontinuity in the waveform. For example the sudden transition in this sine wave:



is heard as a loud click. The solution is to perform a cross fade or cut/paste to avoid such a transition.
