Video file sizes larger after trimming

[pops2380]

I kept my S10 around for as long as I could. With the S10, when I cropped and trimmed videos, the MB file size would get smaller, as it should.

Now that I've upgraded to a S25, I'm noticing that when I trim & crop, the file size gets bigger! A 30 second video gets trimmed to 10 seconds, with the same 720x1080 and 30fps, and it saves as larger? How is that possible?

I even noticed that with the touch & hold slo-mo video viewing option, when you save the slo-mo clip, the file size is actually OK. *BUT*, if I take that exact same video, make it slo-mo through the editing process with the exact same slo-mo speed, length, resolution, & everything, it will save the copy 2-3 times larger!

What did Samsung do???!!!

It's all about bit rate and codecs. Video isn't as simple as less seconds less file size.

The codec and bit rate of the original video is probably different to that of the exported video.

What's probably going on is either when you export the video you it set to use h264 and not hevc or samsung increases the bit rate for exported video to stop quality degradation.

If you wanted to shrink files, just get an app that lets you re encode video

Yeah I adjusted the h264 & hvec stuff and there's still a difference. 

Oh well, I just decided that whatever videos I want to edit, I'll do it on my S10 and then Quick share to my S25 after I'm done
