user9195: I shot some footage on a Sony a7s at 59.94 fps so that I could slow it down in post to achieve a smoother camera movement. But when I interpret it to 23.976 fps in Premiere, it looks like it's dropping frames. It looks super glichy and terrible. When I scrub through the interpreted clip frame by frame, it looks like it has duplicated every frame. Each frame is held for the length of two frames. What can I do to slow the footage down so that it looks smooth?
I am especially confused because I've used this technique in the past with footage shot on a Canon Mark III and footage recorded through a Shogun. When I interpret that footage to 23.976, it looks perfectly smooth.
Things I have tried with the Sony footage, none of which worked:

Interpreting to 23.976
Dragging 59.94 clip to 23.976 sequence and slowing it down to 50%
Frame blending
Opening the clip in After Effects and interpreting to 23.976
Selecting "Pixel Motion Blur" on the interpreted AE clip

I am using Premiere Pro CC 2015. Any help would be much appreciated.

user6330: Since this has worked with Canon footage in the past, my best suggestion would be to import your a7s footage into a 59.94 fps sequence in Premiere, export that sequence (in 59.94) in a universal format like H.264, then re-import that clip to Premiere and try slowing it down to 23.976. My guess is that Premiere isn't playing nice with whatever codec/format the a7s footage was shot in.

user9195: I figured out the problem. My shutter speed was set too low. Turns out it needs to be double the frame rate in order to achieve a smooth motion when interpreted to 24 fps. Should have thought of that before I shot. Oh well. Lesson learned.
