Part 6: Change Video Frame Rate using Premiere

You could also make use of the Premiere to adjust the video frame rates of a sequence videos for playing these videos at the same video frame rate, though this might result in quality loss. If you want to simply change the frame rate of the sequence, just go to “Project > Sequence > Sequence Settings” and change the timebase to your new frame rate.


It should be noted that any footage that you then add to the timeline will conform to the new frame rate, which might reduce quality as mentioned above. If you want to use 60fps clips in the 30fps sequence at half-speed, then right click on the source clip and select Modify > Interpret Footage. This will make sure every frame from the 60fps is used in the clip and will look cleaner. DO NOT do this by right clicking on the clip and setting the speed to 50% (well, you can but it won’t look as nice) Essentially that would take the 60fps clip that is now playing at 30fps, and slowing by 50% would than drop that to 15fps that Premiere would then have to go back and re-interpret those now-missing frames to get back to 30fps.
