Samsung S10 merges my UHD(3840x2160) Videos and outputs the the file at 1080p Why?

[Android Central Question]

I record a video as UHD(3840x2160) the option one below UHD 60fps(3840x2160).

The video is nearly 14 minutes long so the video is split by Samsung as per 4k recording requirements.

I merge the clips using the samsung galaxy s10 built in video editor.

Both clips are UHD(3840x2160) shot in 16:9, landscape mode.

It outputs the final video of the two merged clips as 1920x1080p.

What is the reason for this nonsense?

Can somebody please help, I have no idea why something so simple is like this.

If I record on the phone in uhd, the phone splits the clips as uhd but then combines them as 1080p, that is of no use, if I wanted 1080p I would have spent far less money than I have on this piece of technology for recording video.

I will be forever grateful if anyone has any ideas.

Thank you.

Welcome to Android Central! How big are the files? I think there's still a 4 GB filesize limit for videos, even on Internal Storage -- something that might finally be fixed in Android 11.

You miss the actual question I ask, I am fully aware of why the files are split at 4gb, that is not the problem, the file splitting is not the problem. It is the file merging of 4k videos that outputs the merged video at 1080p. Why? That is what I need to know.

Not sure the point was missed. B.Diddy is stating the 4GB limit will affect the output hence loss of quality to stay within the 4GB limit

ahhh so not only does the video split because of the fat32 limit, it is actually in this case, specifically because, wait a minute, no it is exactly because of the fat32 file size limit, legends, thank you guys, I will try with an sd card formatted ntfs. Nice one for leading the charge brothers/sisters. Thank you for clarifying my misunderstanding @Galactic Zoo, thank you to original reply for helping get me along the way

Peace.

I think it'll still be the same with an NTFS SD card, because it's a legacy code thing, and not specifically dependent on the media.

It's also possible the video merge feature is limited to creating 1080p movies, so any 4K movies get downsized. I don't know this for sure, but it wouldn't surprise me.
