How to fix double outline lag in video footage?

[Linnjeanetter]

Help! This is from an old video footage from 2016. I thought there was nothing to do with the lagging back then, but I remember I fixed something similar not that long ago. I just can't remember what I did or what this problem is called. Every time there is a motion, an outline apears around objects ect. It kind of look a bit delayed and everything looks there is twice as much of everything. The video was filmed with a Sony a6400 camera.

please tell us the properties of your media files.  Wondering if by any chance your footage is interlaced.  If so, you'll need to deinterlace which is difficult to do without losing quality.   But...  if this is just the way it's looking within Premiere, it may not be an enormous issue depending on your delivery format...

Quick look online about the a6400 and it appears it can record 'interlaced'. Which as mgrenadier suggests may be the cause of your issue. So you'll need to deinterlace the footage or work in an interlaced sequence. I believe the a6400 can record at 4K though ... so if this is the case at least you are starting with a high quality image before deinterlacing and throwing away half your resolution 😞

can 4k be interlaced?  I have no idea, just curious....

Does not look like interlaced to me. (too) Fast panning?

I think the way it looks has to do with the scaling of the viewer...  I've been working on a bunch of old standard def documentaries getting them ready for live stream events and interlacing sometimes looks like this depending on your sequence settings and scaling.   I was making myself crazy with this when I realized nobody really cares...  and the quality sucked since the best sources I had were not great dvds...
