Blurred Movement

[TheLeveller]

Hi - I had a quick look through for an answer to my question, but couldn't see anything. Apologies if I missed it though.

Can anyone give me tips on how to fix a blur with moving images. I've attached a screen shot of what I mean. The image is blurred either for something which is moving in shot or if the shot rotates (then everything gets a little blurred).

I've been filming from my Mavic 2 in 4K 3840x2160 (30fps) and use Movie Studio Platinum 14.0 for editing. I've simply been importing the files into the software, editing the clips I want, then hitting the "Make Movie" button and selecting .mp4 as the output file type.

I appreciate this is obviously a very basic way to try to edit the clips together, so any tips on how to best optimise the output either by adapting the input or using the software tools would be very useful.

Thanks, Richard

This is something that you need to control at the input stage with shutter speed - ie when you actually record the footage. It's very difficult to change afterwards with editing.
If video is the final output then you actually want some blur for the video to look natural - if the shutter speed is set too fast, then you'll get what's known as the rolling shutter effect, which makes footage look less natural / worse.

If your final result will be a still, then you'd need a very fast shutter speed when recording to capture an image of a moving thing with no blur.

This explains it all pretty well.

Rather strange blur pattern you have there, doesn't really look like a shutter blur, does it look like that straight off the camera?

If not, maybe consider using different editing software.

Shutter speed too fast causes "jittery" motion where everything appears to skip around the scene; particularly garish with faster pans.

Faster shutter speeds will reduce the rolling shutter effect, not increase it...

Is it blurred on your original files from the mavic, or only in the .mp4 from Movie Studio?

You need to post the actual footage before/after editing for people to understand. That tiny still indeed looks weird but doesn't pinpoint to a specific issue.

Thanks for everyone's replies. This is the same still directly from the drone footage showing the natural blur (which is obviously fine). Guess this points to an editing software/formatting/rendering issue.

Yup. Looks like you rendered interlaced video.

How is this fixed?

Look for an "interlaced" option in the export settings and uncheck it. Could also be a box somewhere that has "1080i" selected instead of "1080p"...

Thanks, I'm always calling that the wrong thing - I do indeed mean faster (to reduce RSE)

I can't see an interlace option to uncheck anywhere. There is an Interleave option, so have unchecked the box and will see if it makes a difference. Have also selected 1080p rather than 1080i. Thanks for your suggestions.
