How to fix mismatched audio and video frame rates
Choosing different frame rates for your audio recording versus your video recording is a really stupid mistake. I would never be so thoughtless, and you, dear reader, certainly would never do such a thing. But for the sake of argument, let’s pretend that hypothetically I happened to have recorded some audio at 29.97fps for a recent project, but the matching video was at shot at 30fps. With no possibility of a reshoot or overdub, I really needed to get the audio and video frame rates to match. Again, I would never make this mistake, but if I had, this is what I would do to fix my screw up.
The Fix for a Purely Hypothetical Scenario
- Record some audio at the wrong FPS. Way to go!
- Fire up the application Izotope RX. I used version 7 for this example and cannot recommend it enough. This is not an advertisement. I’m simply a fan of this software suite. It has saved and improved countless recordings for me.
- Open the Preferences for RX and select the Misc tab.
- Set the “Time scale frame rate” to your destination frame rate (the frame rate of your video).
- Click OK to close Preferences.
- Open your audio with RX.
- Make any edits you desire.
- Save or Export your audio.
- Import your audio with the corrected frame rate into your video editing software and time align it with your video.
- Wipe your brow and breathe a sigh of relief.
Let me know if this worked for your friend or co-worker, because, again, like me, you would never make this mistake.
I’m posting this article because when I try searching for solutions to this problem the typical results are mostly professionals on forums with their stance: “THE RIGHT WAY TO DO IT IS TO RECORD IT RIGHT THE FIRST TIME, NOOB.” Yeah? Well you know what? No.No Comments >
