  • Filmed in 60FPS but playing back as if shot in 48FPS (on 23.976 timeline)?

    Posted by Philip Knowlton on December 17, 2016 at 1:19 am

    I filmed something at 60FPS, and in Premiere have been editing in on my 23.976 timeline after doing the ‘Modify > Interpret Footage > Assume this frame rate: 23.976’ step. But some of the footage is playing a little too slow for my liking, so my question is, if I wanted it to play back as if it were filmed at 48FPS, what would I set the ‘Assume this frame rate’ to?
    My math game is not that strong, obviously. Is there a chart somewhere that I could use? thanks!

    I think you might need to do this in two stages.

    Take the media into Adobe Media Encoder. Use Interpret Footage to make it 48fps, then encode it to ProRes or some other high quality codec. Then take the new ‘master’, which is now truly 48fps, into Premiere and Interpret Footage again to 23.976.

    I think if you try to do this the way you were proposing entirely within Premiere, you will end up doing a “conventional’ speed change, which will cause blended frames.

    Thanks so much John. I’ll try that and report back!
