News VLC demoes AI-generated subtitles as it hits new milestone of 6 billion downloads

Nice, if CC isn't built in to the stream already. But I'd be far more impressed if VLC could include or at least fully document the procedure for installing BD and 4K support in the first place. Current process is poorly documented, not directly supported by VLC, and hacky/unreliable. At least in my experience. Changing that would be a more significant improvement than just well-done CC.

Yeah, in 2025 one of the best uses for "AI", upscaling videos to a higher resolution with no/minimal loss in quality, should be the priority, not "AI" for closed captioning.

The offline captioning is a good thing to start with.
We hope also in the upscaler, but for me it is significant only if it will works offline.
 
When someone tries to get me to look at a youtube video, I typically just go to the transcript and skim it, so I don't have to waste time watching the whole video. Based on that experience, I can say that AI-generated subtitles are better than nothing, but woefully inadequate, depending on the type of content. It's great for a first cut and to generate the timing, but then you'd really want to do some hand editing to fix the various errors.

If you don't speak Japanese, then watching an upscaled super-high-resolution video in Japanese doesn't really help. On the other hand, watching a medium resolution video with subtitles in your native language is a really big help.

I take it you're speaking from experience? Based on what I've seen of subtitles in my native language (again, just using youtube as my data set), I'd be very worried about taking sketchy auto-extracted dialog and then passing it through automated translation.

Furthermore, there at least used to be no shortage of fansubbers who would even do the whole process by hand. With the range of automated tools available today, it should be much less work for them to make the same high-quality edited subtitles.
 
This would be a much more useful feature if VLC supported sending captions to a casted device, which you still can't do nearly a decade after Chromecast support was added.

Does Chromecast support captions overlay? If not, then VLC would have to re-encode the media, which might explain why they haven't done it.

That's actually the reason, but a number of other video apps do just that to enable the feature. I've since abandoned VLC for that reason, despite it being superior to just about everything else in just about every other way.

That's not a VLC problem, that's a Blu-ray Disc Association and whoever own the patent for an hardware accelerated codec for hevc problem. It feels hacky because that's what it is.
