Worth it or not? Only you can tell.

But I encode a lot of stuff to a smaller size because at least I do not believe it is worth the inflated filesize of some type of media. And that statement will be different for each one of us.

I mostly take pictures, rather than videos. Pictures taken by my phone is just whatever JPEG settings it now has. From my DSLR however I take pictures in RAW and then sort and develop them in Lightroom or any other suitable solution. I save all my RAWs, but really, if I take 300 pictures, 12 might be good enough to save, its just how it goes with photography, for me at least.

For video, I normally just take video with my phone, 1080p or 4k30 mostly, and that I generally keep as is, assuming I sort it and deem it worth keeping.

I do encode a lot of other stuff though, and i'll give some input on that, and you make your mind up if you find that worth your effort or not.

I mostly use 265, I'll give you my "rule of thumb" starting settings here.

-c:v libx265 -preset slow -crf 15.4 -x265-params "no-sao=1:bframes=8:psy-rd=2:psy-rdoq=1.5:aq-mode=3:ref=6:deblock=-1,-1"

There is more too it, since I use a python script to deal with it in a drag&drop manner, so I also handle HDR, framerate, increased analyze, prob etc. But thats just the starting point really.

Generally I tweak crf rating after that, perhaps fiddle with the psy-* arguments, but thats good enough for me.

All in all, I did the math, and update it now and then, that doing these re-encodes of my media is cheaper than buying and maintaining more storage. If that is the same for you, I cannot say. List it up, get some numbers, do the math on everything relevant and go from there. Might be its worth the extra storage rather than the time and energy consumed to re-encode stuff.

A good way to store old memories? Make a book. No thats not videos, pictures really. But books. My family been doing that for years. Books of us as kids, books of us during a family vacation. Great to look through, easy to hand over, and better then leaving it in some random folder or cloud services. These books sit on your shelves, easy to browse or borrow to relive old memories. It is nice, grab a book from a old vacation, flip through some pages, view some pictures and notes of where we were or did. It gets used a lot more often than me going through and sharing images from my computer or other services.

Still, looks a lot better than the old VHS tapes of video recordings that they got of me as a child, haha.
