24 fps issue

Hello everyone, just got my Lumix G7 and i have a weird export issue. Im recording at 60fps 1080, mp4 file and in premire my suequence is 24 fps. when I render the video in 24 fps timeline, the video is very choppy.

My shutter is 1/125 so it's double the frame-rate.

heres an example:

That's because your recording framerate (60) is not an exact multiple of your timeline framerate (24) so Premiere is unevenly dropping frames to play it back at the correct speed.

Is there any particular reason you need a 24fps project framerate?

Ideally you should be using a timeline that matches the framerate of your footage assuming you want to play it back at normal speed. A 30fps timeline should look okay too because it's exactly half of 60, so Premiere can just drop every other frame to make it fit.

There's little point shooting at a higher framerate than your intended project target unless you're planning to slow the video down for effect, you'll just end up introducing the sort of artifacts you're seeing.

Hope that helps.

So many dropped frames when going from 60fps clip to 24fps timeline.

A quick google search says that (in premiere):

1. Interpret the 59.97 footage to 23.98.
2. Drop the interpreted footage onto the 23.98 timeline.
3. Adjust the speed of the clip on the timeline to +250% with optical flow enabled.

You wont get the blur if you shot natively 24fps/180 degree shutter, but it shouldn't drop frames.
