I have rendered the original DJI Osmo Pocket 4K at 60FPs


  1. I tried to render and the output file has lots of motion/jerky movements

  2. I tried again and changed the frame type to "Top Filed First" from "Progressive" which seems it fixed the problem depsite fast rendering was ON and also I have tried to rurn off fast video rendering with Prosseive which fixed the issue also, so I assume the issue is from Fast video Rendring ?



Im sure some has faced the same issue, is this the correct way of fixing motion/jerky issue post rendering or there is something else to do other than turning the fast video rendring option

there is also in properties "use deblocking and use dynamic GOP" do i check or unckeck if they ever help

I have attached a copy of the video details as image (left one the new rendered one and right is original) just to show that FPS andsize is same, so i dont think the framerate has to do anything with it

Regards

Hi,
No-one's picked this up, so a few details are required. I'm assuming you're on Win OS for the following suggestions. If you are on a Mac OS please say so.

Primarily, what is the production profile used for the jerky output file?

In general, unless required for special purposes, the final production profile should match the source footage file for best results.
Not essential but a good starting point. PDR has a Profile Analyser function which will suggest the optimum output profile for your timeline contents.

Your system specs might be an important factor so you might consider attaching a DxDiag as a quick way to provide comprehensive system info. https://forum.cyberlink.com/forum/posts/list/97579.page#post_box_392510

If you have determined SVRT off cures the problem for the time being, then perhaps other members might have some further suggestions if you provide some more details.
