Hi folks,

I just exported a very short clip from my Mavic2Pro drone which seems to be very twitchy. Any ideas why this might be happening?

I'm on a Win 10 PC, Resolve 17, Mavic footage is h.265 D-Log. Shot at 29.97fps, pulled down to 24fps timeline.

Here is the YouTube link to the short clip

Can you supply a short original clip that exhibits this so others can test?

Upload it to a file sharing site and post the link.

That's messed up.

You changed the clip's speed to match the timeline in Clip Attributes?

What were your Delivery settings?

Does it play properly in a 29.97 FPS timeline?

Could you try optimizing the media to DNxHD before you drop it into the timeline.

(I've read again and again about messing with time with H.264 -- and I'd assume H.265 as well -- clips being the cause of various issues. H.264 is not intended to be played except in frame order. Shouldn't have issues in a non-realtime situation, but I've read about issues with frames jumping, etc, with various programs. My guess is it's usually on Windows systems using Nvidia H.264 decoding, but I'm not sure.)

Hi all!

Thanks for the replies, I appreciate it

. I checked a couple of things, if the clip plays in a 30fps project/timeline, if the "Bypass re-encode where possible" was checked and so on... Finally, I settled on a transcode. I simply transcoded to DNxHD HQ, re-imported and replaced the dumb h.265 files. I should have known better and done it in the beginning.

Thanks all once again!
