Interpreting 59.94 to 23.976 turns out jittery, even while converting in AME

Hey,

I'm working on a 23.976 timeline and no method works:

Interpretting footage, speed ramping, Optical Flow, Frame Blending...

The footage always turns to be choppy.

I even tried re-encoding using AME while interpreting the footage, and it still turns out to be choppy.

The footage is in ProRes 422, recorded using the Atomos Ninja V and the Sony A7 III.

Has anybody encountered the same problem?

I resolved this by purchasing an atmos 2.0 hdmi. It was about 45 bucks but that was my bottle neck. The cable from R5 to ninja was not enough to support the Frames at 60fps so basically it was just doubling the 29.97 @ 59.94... it was a nightmare and I was pissed! But the cable sorted things out! Hope that helps.

For anyone still having this issue with the R5, TURN OFF LOWRES STANDBY! Make sure you have no card in camera and BOOM - Smooth externally recorded 60p with the R5.

Any resolution to this? I too have horribe skipping 59fps footage out of the Ninja 5 with my Canon R5.

This product has been very dissapointing as it has not behaved how it is supposed to with this camera in more ways than one.

Unfortunately I have the Atomos 2.0 HDMI and this happened. What ssd are you using? I'm using the WD Blue 1tb ssd on their approved list of drives...such a bummer. Did you have any success making your footage work before you bought the 2.0 cable?

Ok, so interpreting is usually the easiest and reliable method to make them slow-mo. You should get a smooth frame for frame mapping if you interpret to 23.976 and put it on a 23.976 timeline. If you step through the sequence frame by frame, do you get a consistent cadence? Ie. no duplicate frames and no skipped frames?

What exactly do you mean by choppy? Perhaps it's just a playback issue?

It's not a playback issue. If I use "Interpret Footage" and assimilate 23.976 fps Premiere duplicates frames instead of playing it smoothely (I tested it frame by frame). Meanwhile, on DaVinci Resolve 15 it slows down just fine, so it seems to be a software issue.

So are you trying to deliver a 23.976 sequence but your footage is 59.94? You will have to drop frames obviously (so will never be as smooth as the original). There will also be very little motion blur with a high frame rate so when you drop frames it can give you a slightly staccato effect. Or are you trying to play the footage at 23.976 so it will be slow-mo?
