Pops on Audio Cut, any techniques?

Post by meinthecorner »

I've been creating a film for the local museum. It contains a number of interviews which are cut at various places.

During some cuts, there is a noticable 'pop' or 'crack' noise when the interview scene changes from the interview to an image, the image has no audio.

Are there any techiques to try and soften or remove these pop's? I've tried fading the sound down using the fade option, but this makes it harder to hear the end of the sentence.

This isn't a problem when the interviewee has a natural pause at the end of the sentence, but sometimes the cuts are pretty abrupt, which is where the pops tend to crop up.

Can you tell us the properties of the video you were filming in, please? Without such information -- and any other information on any editing you may have done -- could be important.

For instance, in the past, I would get the occasional pop when I filmed in mini DV/AVI format, then captured using the Type 2 DV encoder... VS seems not to get on well with Type 2, whereas it has no problem at all with Type 1...

You also tell us nothing about the version of Video Studio you are using, and of course you have not filled in your Profile settings, so we know absolutely nothing about your computer set-up... It's a bit like you ringing up a motor mechanic and telling him that your car makes the occasional popping sound. But you don't tell him the make of the car, where you were driving, and what you were doing at the time, much less anything you might have done to soup up the car or which might otherwise have caused the pops.

What do you think the mechanic would say to you? :roll:

Sorry again :(

File: PAL HDMV
Video: H.264 Upper Field First
Atributes: 24bits, 1440x1080, 16.9
Frames: 25.00
Rate: Vairable Max 12000 kbps

Audio Type: Dolby Digital
Attributes: 48000 Hz
Layer: None
Bit Rate: 256

I've tried matching the audio, using PCM, MP3 Etc but cant seem to nail it.

These pops appear if I'm encoding into different formats, such as AVCHD, DVD Mpeg or xVid.

Hi

Try fading out the audio for the last second or half second so that you don't get sudden transition from sound to no sound, you can use the rubber band or use the fade out option for the audio.

Is the audio still "attached" to the video clip, i.e. you have not Split the audio?

If so, try using the Split Audio function to put the video clip's audio into the audio track.
