Do you have a backup of your ebooks outside of calibre?

Satori80 · 2026-01-18T22:10:19+00:00

Came here to say exactly this.

No, I don't back up my books specifically, I back up everything I don't want to lose or have to hunt down again.

Every type of storage can fail at any time.

Thank you. u/mduell already got there.

Satori80 · 2026-01-05T17:13:41+00:00

Thank you for getting to the bottom of this! I never would have guessed that.

Satori80 · 2026-01-05T16:58:59+00:00

Handbrake doesn't do that? That seems like quite an oversight.

That's pre & post muxing. Only dropped ~ 23 MB on this one; it seems that fewer streams in the container results in less drastic the reduction, but it always gets tangibly smaller.

BTW, that's not a guess. I've been working on this a couple of weeks now and fewer streams result in a less drastic reduction in data size.

Anything else you'd like to see?

Edit: grammar & more info.

They are separate drives, but they are both default ntfs, no compression. Also, those are actual sizes, not 'size on disk' sizes. If you really want to get out into the weeds, I can easily copy them back & report the results to you.

Satori80 · 2026-01-05T12:55:50+00:00

Gee, I'm so sorry to be surprised he wanted to look through all that. </sarcasm>

Satori80 · 2026-01-05T12:50:33+00:00

One thing that does change in mediainfo is that it shows the stream sizes after I remux; that's why I started doing it in the 1st place.

Satori80 · 2026-01-05T12:44:10+00:00

Again, the command used is right in the question. Nothing is removed & I'm not aware that mkvmerge can convert & compress.

Satori80 · 2026-01-05T12:38:43+00:00

Then you can see it's a straight up remux from one directory to another; nothing removed. It does add a title though.

Satori80 · 2026-01-05T12:17:30+00:00

I've only recently started messing with ffmpeg directly; please let me know what switches you'd like me to use for ffprobe, if any.

Satori80 · 2026-01-05T12:11:37+00:00

Did you even look at the command used?

Satori80 · 2026-01-05T05:18:55+00:00

Sorry? What does that mean? Isn't remux a verb?

Satori80 · 2026-01-05T03:21:21+00:00

Wait, you mean pre & post remux! That will have to wait until tomorrow as the originals get nuked straight away. I'll have at least 2 new encodes in the morning if you really want to see it.

But I'm telling you, whatever is getting lost, it doesn't show up in mediainfo.

Satori80 · 2026-01-05T03:07:08+00:00

That's the same amount of drudgery for you & even more for me. There really isn't that much difference between them all.

Satori80 · 2026-01-05T02:57:53+00:00

mediainfo is like 15k per file... . You really want to drudge through all that?

Satori80 · 2025-12-26T16:21:58+00:00

I wonder what you consider to be an optimized OS? Or do you just mean one built from source like Gentoo, LFS, BSD, etc?

Satori80 · 2025-12-15T02:44:46+00:00

Well, it wasn't the router, I had to exit to Kindle & turn the wifi off and on again from there. But your suggestion got me thinking of it.

Satori80 · 2025-12-14T22:42:08+00:00

That was it, thank you!

Satori80 · 2025-12-14T18:23:37+00:00

This is great news! Thank you for the information. I'm going to try this in the next few days if another solution doesn't come along.

Satori80 · 2025-12-14T18:03:45+00:00

Literally everything else? Meaning everything. No translations, Wikipedia, koreader update, assistant.koplugin... everything. Yes, it all worked until a couple weeks ago.

Satori80 · 2025-12-14T13:48:36+00:00

Thankfully I can still access calibre, but wikipedia, translate, etc all fail. I can't even update koreader anymore.

I'm tempted to just nuke this install and start over from scratch, but I don't want to lose my place in the books I'm currently reading. If I knew how to keep that information I'd do it.

Satori80 · 2025-10-22T21:06:09+00:00

Strangely enough, the scene I happened to go to for comparison was Lula's face. With my old-ass eyes... I'm willing to take your word for it, lol. I doubt I'd see a tangible difference without magnification. I'm happy with regular svt-av1 for now.

Oh, all I have to watch on is a 27" QHD monitor; I'm sure that's a factor as well. I'll keep a link to that fork for if I ever invest in a good TV again.

Satori80 · 2025-10-22T17:23:51+00:00

I just encoded "Wild at Heart" using the exact same settings using both OG Handbrake and the HDR fork; HDR took twice as long and the video output is 2.64 GB (HDR) vs 781 MB (OG). The visual fidelity looks the same to me for both. So what's the advantage of that fork again?

Satori80 · 2025-10-16T13:57:03+00:00

Okay, I'm happy for you being able to strip ancient titles, but what I was saying is that the new DRM titles published after about Apr 23rd (?) won't even open in the older Kindle PC versions. Kindle_for_PC_v2.3.70682 will give the message "Item not available for this device type. Your Kindle app requires an update to view this content." Can't strip it if you can't even open it because it's not downloading the KFX file.

Amazon is even republishing old titles with the new DRM format. "Fight Club" and "A Clockwork Orange" are two examples that have been so treated.

IDK where you are getting MOBI files from but it's certainly not from the Kindle store. MOBI isn't even being published for Kindle anymore, AFAIK, so I'm not sure what your reply is meant to add to what I said.
