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?
