It really is gone. You can predict what you think it might have been, but you can't know what it was.

it's gone in a single still frame but across many consecutive frames, the information is spread out temporaly and can be recovered (partially) the same principle of how you can get a high resolution image from a short video, by extracting the same patch from multiple frames https://en.wikipedia.org/wiki/Video_super-resolution

No, it's not "restoring detail". The information is gone.

It is predicting what the information might maybe have been like.

what are you talking about? Of course it's only about playback just like the other 2 alternatives > single best media player out there ... VLC is not recommended.

Literally the first sentence > Hanging out in subtitling and video re-editing communities, I see my fair share of novice video editors and video encoders, and see plenty of them make the classic beginner mistakes when it comes to working with videos. Seriously, you quoted pretty much the only sentence in the whole article that's about plain playback, and even in that bullet point, the following sentence mentions hard…

Literally don't stop at the first sentence!!!

> It turns out that reading the (f.) manual actually helps a lot!

The non-recommendation of VLC vs mpc/mpv is literally for playback as I quoted! MPC also doesn't do any encoding, yet it's recommended

> the following sentence mentions hardcoding subtitles.

And that sentence starts with "Apart from simply watching the video" to tell you the same thing the previous sentence told you - that comparison where VLC was not receommended was about playback, not editing

Nearly this entire HN comment section is upset about VLC being mentioned once and not recommended. If you can not understand why this very minor (but loud?) note was made, then you probably do not do any serious video encoding or you would know why it sucks today and is well past its prime. VLC is glorified because it was a video player that used to be amazing back in the day, but hasn't been for several years now. I…

> It is the Firefox of media players.

So... the better option?

Many HN readers won't be familiar with the fansub culture that this writeup originates from, so sharing a helpful resource in case anyone is interested in learning more:

It seems really weirdly written. It's written with a lot of authority, like saying "Don't use VLC" and "Don't use Y" yet provides no reasoning for those things. Just putting "Trust me, just don't" doesn't suddenly mean I trust the author more, it probably has the opposite effect. Some sections seem to differ based on if the reader knows/doesn't know something, but I thought the article was supposed to be for the latt…

technically correct is the best kind. who cares if it's obnoxious? take the opinions and agree or disagree with them.

How can I disagree when they don't provide a reasoning behind why something is the better option?

I'm always amazed when I see how many people are unfamiliar with VLC hate. It was notorious (to the point of it being a popular meme topic) for video artifacts, slow/buggy seeking, bloated/clumsy UI/menus, having very little format support out of the box, and buggy subtitles. I assume nowadays it's much better, since it seems popular, but its reputation will stick with me forever.

>It was notorious (to the point of it being a popular meme topic) for [...] having very little format support out of the box ??? I thought the meme was that it played basically everything? At least compared to windows media player or whatever. The other items I can't say I've noticed, but then again I only play the most common of files (eg. h.264/h.265 with english subtitles in a mkv) so maybe it's something that onl…

Yes, that was in the 2000s though. During the 2010 VLC started falling behind because its shortcomings overweighted its capabilities.

VLC has always caused problems for me when seeking backwards (graphical glitches). mpv has never caused any issues in this regard.

VLC and mpv literally use the same underlying codec library. (As well as ffmpeg.)

So? Here is the post where VLC dev explains why you can't seek 1 frame back (you can do that in MPC and mpv) https://forum.videolan.org/viewtopic.php?f=7&t=126609&start=...

MPC-HC is still a thing? I remember installing that (and K-Lite Codec Pack) on Windows, back in the day. Haven't used, or even thought about MPC-HC in years.
