Hi Dave,

Thanks for the reply. I am an audio engineer, a DJ, videographer and video editor. I never done this before, that is compining all the above skills in one project. I can gradually change the speed of the music video clip with time remapping->Speed. However, the pitch changes as well. I could use the pitch shifter effect for the audio track, but that is laborious, since I have to rely on my hearing every time I need to achieve that speed ramping (The mashup has 100+ songs).

So to rephrase and be even more specific, is there a way to maintain the pitch automatically, while the speed of the clip gradually changes with speed remapping?

Hi Ann,

Thanks for the reply. Audition will not do, it adds unnecessary steps, all I need is an automatic pitch shifter to follow the speed remapping

Hey Dave, I was hopping on a more automated solution. It will take more time but can be done as I described!!!

Changing music audio speed (BPM) while maintaining pitch will require Audition. Premiere Pro on the timeline won’t get you there.

An ongoing, continued increase in speed while maintaining pitch will involve cutting up the music into discreet pieces, and gradually increasing the speed on each piece. The more small pieces, the more gradual the ramp-up in speed will appear to be. Fewer pieces, and each change will become more obvious.

There’s no means I am aware of that would give you an “adjustment wheel”, so to speak, allowing you to very gradually ramp up speed while maintaining pitch. Something may exist, but is likely specialized.

If you are unaccustomed to using Audition for managing speed, the basic techniques are demonstrated in this video.

Thanks Jon for the reply, I appreciate it. Still researching, I will come back soon when I have more concrete methodology for others to know as well

I think you’d need to look into DJ software. Sounds like something that a DJ might be interested in doing. Since you are a DJ, you should have resources there. I’ve never heard anything like that in any video editing application.
