  • Why does it sound so bad when you change the Clip’s speed?

    Posted by Rambosha on October 21, 2005 at 4:59 pm

    I’m cutting together a bunch of interviews, and when I speed up or slow down a clip, the sound gets a huge echo and becomes muffled. Sometimes I need to only alter a portion of the clip, so the sound distortion is especially noticeable when the same person’s voice suddenly becomes a lot clearer.

    I know “Maintain Audio Pitch” must have its limitations, but is there any way I can reduce the distortion further? Thanks.

    When you slow or speed up a clip, the audio is equally affected… its just the nature of the beast. So, if your interviews are “talking heads” with synched audio (voice andmouth matching), you can’t slow it down successfully.

    If it is just a VO over video of people, then, unlink your audio from the video, and only slow down the video clips.

    Curious only but..

    Why would you speed up a clip of someone talking (interview) unless you wanted an effect?

    First of all, it should be possible to slow the video down and set the audio to remain the same pitch. However, this is not perfect, and it is entirely possible that you could tell the difference between the effect and the normal speech. Perhaps the solution is to speed it all up.

    One reason to speed things up is to make the interview go faster to fit into a shorter time requirement. Anything under 10% speed reduction or so should seem pretty normal.

    This still seems to be a problem 11 years after this thread.

    I’m trying to edit a film where the sound has been digitised from shrunken magnetic tape. The shrinkage varies throughout the film so I have to cut the sound to multiple pieces and change the speed differently according to the image.

    Is there any way to improve the sound quality within Premiere? Working with Audition in this case is quite impossible.
