I am planning some videos when the weather improves and am wondering how video editing programs treat video with slightly different resolution? I use NCH VideoPad.
To explain, I will be filming with my DJI Mini 3 Pro (and possibly also DJI Mini 2) along with GoPro 5 and GoPro 11. All will be set to 4k25 but I believe the GoPro’s have slightly more pixels at 4k than the DJI’s?
Is the video editor likely to resize one so that all are the same? And is it likely to go for the higher pixel count or does it depend on which is used first in the edit?
Or does it just leave them as is?
Not that I’ve used NCH (did try once - a long time ago) but all video editing software I’ve uses has settings that allow you to specify.

In Adobe Premiere, it sets the overall sequence to the resolution and frame rate of the first clip you drag in. If any subsequent clips have a difference resolution and/or frame rate, it is up to the user to change them manually. I.e. full control.

Similar in Resolve. You set the timeline to a resolution/fps and it offers to change the fps should the first clip be different.
Clips of a different resolution you can set the policy for the project …
… or rescale specific clips.
Would I be correct in thinking it would probably be better to go with the slightly lower resolution of the DJIs as they would be the majority of the footage?
Yes, that this is also the same in Premiere.
I don’t think the end result at those resolutions will look a lot different.
I think I’d tend to always go with the default 4k resolution of 3840x2160, and if I were to go with one or other source resolution I’d go with the one of which there is more footage, and hence modifying only the smaller amount of footage.
If the GoPro content would crop to the smaller without loss of important edge detail, I’d possibly maintain the 1:1 pixel ratio importing at native resolution and losing the edges. (“Centre Crop with no Resizing” - in those Davinci Resolve settings.)
I will record some sample footage tomorrow and try it out before my real projects.
I can’t use Davinci Resolve, it just crashes in my old laptop, but VideoPad works. Though sometimes you have to leave it running for hours to get the job done.

I only mention DR and it’s settings as those are the ones that are most familiar to me (and I can screenshot), and as a guide as to the settings to look for in NCH (and most video editing software), since such resizing is a pretty common task.
I assume you probably know this, but you make life much easier for yourself if all source footage is recorded at the same frame rate.
This is much more important for syncing stuff up than the slight difference in resolution.
Apologies if you already know this, but it bears repeating, learned it the hard way as this has bitten me more than once.

Edit: reread and see you set both to 25fps, so all good.
