Q: Mixing Frame Rates - How can I fix this without Re-Editing?

Working on some tutorial-style training videos where I have live footage of my talent introduce themselves and the topic they are covering, then a screen cap recording of them showing the process, and then back to my talent to wrap up.

 

I think I may have started to make a mistake though when it comes to frame rates as my camera footage portions of my finished product appear to be ever so slightly sped up. It's not chipmunk speed but I noticed the voice is slightly higher and faster than the rest of the tutorial. I've made a mess of frame rates and so I did a little research into what is wrong. When looking into it I discovered..

 

    • My camera footage of the intro/outro was shot on a Canon DSLR at 23.98p (But when i synchronize clip with the audio recorded from my external recorder it shows as 23.98i in my project)
    • My screen recording that was recorded from the computer in Screenflow was exported at 30p but whens synced with the audio recorded from my external recorder shows as 30i
    • My animated intro bumper form AE says it is 25p
    • My project says its 25p in the settings.

 

 

I've already edited out several of these tutorials, so I need to know...

 

What I can do to fix my current videos?

How do I prevent this in the future as we start to record more of these?

 

Has anyone encountered this? Any ideas?
