TIMESTRETCH - How to speed up audio, maintain video sync?

VideoPro wrote on 9/21/2021, 4:43 AM

So far I have tried every suggestion I could find on this forum.

Nothing seems to work.

My goal is to speed up the voice of the person being interviewed, while maintaining the video time in sync.

The MEP time stretch does not seem to want to work, it cracks and sounds like lil john vocoder in some places. I am moving from 120bpm to 130, a tiny amount?

I bought Sound Forge and loaded that up, edited wave externally, does not work, simply puts the wave file out of sync with video.

I tried Music Edit 3, same thing.

Anyone else conquer this yet?

Is there any other way to do this by not leaving MEP?

If I must leave MEP, and use a third party tool, do you recommend any?

How do I get the audio and the video clip back on one track, so that I can export it again (export the particular clip) there are dozens of small clips which need micro editing, and I need to find a simple and quick way of saving the segment of audio and video out of MEP, so I can take it out to a 3rd party software for speeding up the clip, and then re-import it.

p.s. is VIDEO PRO X, better or worse, then MEP Premium? I would buy that if it is better, but I am unsure

Premium is the highest version of MEP.

Use the normal time stretch tool in the effects section using the following settings to maintain pitch.

Watch my tutorials on Everything Audio:

I am assuming that the audio was in sync with the video when you started. If you speed up the audio, obviously you have to also speed up the video at the same time by the same amount. For this, just use the Speed effect or, as Ray indicated, the Stretch tool which is actually the Speed effect.

I checked a clip in VPX12, changed the Speed to 1.30 and the audio sounded fine, just faster.

The second setting, the one I did not use in the image I gave above will alter the pitch relative to the speed of the clip. The one I used keeps the pitch the same. Both should work smoothly.
