Here's a weird one. I'm shooting 1080p60 with intention of conforming it to 30 in post (for slo mo). In most, but not all the clips I shoot the footage is stuttery. I check the clip properties, and sure enough, it's 1080p60 - but, when I click through the video I'm seeing each frame recorded twice. Essentially it's recording 30 frame rate over a 60 frame stream. Then randomly, maybe every 6 or 8 clips will have been recorded correctly. Anyone else seeing this?

Hi, can you provide the original 1080P 60 files? You can upload into cloud platform and then leave the downloading link here, we need to analyze your videos. Thanks.

Hello,
I've uploaded 2 clips here. #19 is a 60p clip that has recorded only 30 fps. The other clip, #0028, is a 60p clip with 60 fps.

Thank you!
Bob

Both clips to me shows as 60fps but the DJI_0019 2.MP4 one has the duplicate frames you mention.

Wonder of this is an issue with D-Cinelike color profile (  DJI_0019 2.MP4 seems to have been flimed using it )?

What color format was DJI_0028 2.MP4 filmed in?

I've solved the mystery. If I shoot shutter priorty 1080p60 with the shutter set to 60 (essentially shutter off) I end up with the odd 30p over 60 thing. Bump up the shutter speed to 100, problem solved! The problem doesn't happen in "auto" mode. I wonder if I shoot manual mode with the shutter at 60 I'll see the same issue - will try that next.


I suppose the little camera can't process "shutter off". I'd be interested to hear if anyone else is seeing this.

Sorry Sploodge, I didn't answer your question - yes I was messing around with the color settings, though I doubt that was the cause of this. I'll be leaving in d log from now on.

Hi Bob. plz check the anti-flicker. What do you set for the camera? 50hz ? 60hz?

Auto is recommended.
