Maybe webm and mp4 files with multiple language tracks are usually played with a media player, not a web browser?
pretty much every animation u see online nowerdays is a webm, i just think it would be nice if browsers would support the full feature set of it, it would allow to put captions over animations where the captions dont get compressed and hence would stay readable even at high compression
One problem with that use case is that you as the creator doesn't control where (screen position) and how (font face, size, etc) the subtitles are rendered. The browser and user control that, so I doubt they would be widely used for meme because of this.
However, I do agree that it would be nice to have support for it for other reasons.
Is that specific to RIFF/WEBM or something? Because from my limited experience with subtitles, "the creator" absolutely does have control over that. Though it can always be overridden by the client, of course.
Supporting soft subs is a complex topic though. Three formats, font embedding, positioning and animations. It's a ton of effort, and anything less than "full featureset support" will mean they don't render how you design them in your full-set editor and local media play. And there will be differences and bugs, at least for a while. I suspect font rendering with various fonts in a media render context will have it's own set of issues.
I also think it'd be nice, but I can totally see how it may not make sense technically (complexity with its burdens vs need) or economically.
Browsers are already absurdly complex though so… maybe? :P
false, I use websites with significant numbers of gif files for animation.
I mean, modern web browsers are trying to be absolutely everything else as well. Fully supporting a format isn't exactly an outrageous expectation.
I'm not suggesting that it's outrageous. Merely that it's probably not a high priority.
You know what is a priority? AI because fuck knows why.
They need to free resources for important stuff such as ~~U2F~~ ~~WebAuthn~~ PassKeys
YouTube supports multiple audio tracks and multiple language subtitles. Same for Netflix and pretty much all major streaming platforms.
Sure, but most YouTube streams aren't delivered as a single webm or mp4 file, and the language & subtitle selection you're referring to aren't implemented by the browser (but instead by a JavaScript application downloaded from Google). So it's not what OP asked about.
