hi, delete all your media, then go to the project settings and change the project frame rate to the desired. Save and close the settings tab. UNDO (cmd+z/ctrl+z) and the media that you deleted is restored but the change you made in the settings stays the same. This also works if you want to change the mixed frame rate option.

Hey Mark,
There’s many ways to do this. I will write what I think is best.

1- Long way: is to conform only the video to to the desired frame-rate (25 fps I guess) and to keep the original sound untouched. Then using the “rate stretch tool” [R] , you can speed up the video again to match the original audio which is the original video speed. Since all of this can be done without rendering, you don’t need to process the videos one by one before starting your edit.

2- Shortcut: One of the things that I love about Premiere is that you can edit different clips with different frame-rates or/and dimensions on the same sequence!!
Just drag the clip without conforming and premiere will do the job to keep the speed and pitch.

In both methods, if you’re going to export your final edit using 25fps, premiere will convert the frame-rates during export. It will keep the speed and pitch as the original.

Hope this was helpful,
