Add video to existing project (Urgent)

Hey all,

I just got asked to score a trailer for a documentary, but I’'d like to use an existing idea. Can I just import the video to the project, set the fps, and lock the fit? I would have to rearrange a bit, but in the end tempo shouldn’t matter if the video is locked right? I just don’t want the music to miss hits once I send it over.

Thank you!
