Jittery video of fast motion

[y2khardtop]

so I've been covering some automotive racing event lately, and I'm having a real motion with the vehicles video quality being very poor. I have been shooting at 3840/25k frames.

Basically, it looks like the car go 5 frames forward, then 2 frames back, then 5 forward, 2 back etc etc etc. Reminds me of the old 3/2 Pulldown from home theater DVD days.

Anyway, should I be shooting a different resolution/frame rate (even 1080?), are my memory cards too slow, or do I have a hardware problem? Shooting real estate or other low motion items everything looks fine.

Thanks

**I'll post a sample shortly***

the raw MOV file is exactly the same, the white car in particular seems to be bouncing back and forth instead of moving smoothly

I can't see your video link, it says the page couldn't be found. It sounds like the Jello Effect from what you are describing. Are you using ND filters?

Try this, I’ve not used any filters as I’ve had no other issues and have been happy with my PhotoS and videos for the past 30months

Try other frame rates, 30fps or 1080 @ 60fps, that will help. 24fps on fast moving items can cause that effect

You need to speed up your frame rate and shutter speed.

Sounds like a pc rendering problem Do you have any other 4K video to look at on the pc or if you are using the Go app what do the lower quality files on that look like If they’re jittery then yeah you could have a problem
