I did find instances of them actively deleting old subtitles and replacing them with lower quality ones in the back catalog, yes. Which seems indicative of Crunchyroll wanting to eventually get rid of good subtitles altogether.
Keeping the "hard subs" content is a lot of videos as the subtitles were encoded into the video stream.
This makes CDNs and other systems more difficult to utilize because we have a ton of video streams with just caption changes as opposed to just the Japanese audio source + caption files.
It's one of those things that doesn't seem that problematic till you include all the video_qualities to support streaming bandwith. So you also get a #hardSubLanguages * #videoQualities
I’m pretty sure it’s not too hard to implement an ASS → PNG renderer (especially considering vibe coding is now a thing). Then, just need to split out subs that can be actual text somehow from the ones that have to be overlays.
Apart from that... surely they could at least keep ASS subs for the players that support it, and serve “fallback” subs for low-end devices?
You can also use the same kind of segment-based playlist approach on Blu-ray if you wanted to, though theoretically you should be able to use the Blu-ray Picture-in-Picture feature to store the typesetting in a separate partially transparent video stream entirely that is then overlaid on top of the clean video during playback.
We did do inlaid server-side ads that way for a while.
IT just takes an excessive amount of work.
The real solution is just the full support of ASS/TTML/VTT subtitles on all platforms. Usually smart devices are kind of only partially supported.
For instance - casting to a chromecast fallsback to SRT.
You'd see playback issues go up by 1000%.
In the nicest possible way, it is pretty clear that this article was written by somebody who has only ever looked at video distribution as a hobbyist and not deploying it at scale to paying customers who quite reasonably get very upset at things not working reliably.
Only english is the most popular and just keep it. Most of the good hard subs are made for english and that is what people want.
It's really tough when you need to scale these things across 20 platforms.
The good/old subtitles in the ASS format required a more complex playback system than what Netflix/Hulu (and maybe blueray players) currently offer. This could be worked around by burning the subs into the video stream, but then you need to keep separate copies of your (large) video files for each subtitled language.
That doesn't seem like it'd be such a huge problem to me, but what do I know?
The post does a good job explaining the effective monopoly system at play that prevents real competition to provide any pressure to improve or maintain the prior quality.
Assuming each video in its largest bitrate is... 2gb for example, and assuming S3 is $0.025/gb, that's a nickle per month or let's say $0.50/yr for that video.
Next up is reduced bitrates, assume you go from 2gb to 1gb and finally 500mb. Round up and you're at $1/video.
Now duplicate it to AV1 and MP4, and multiply that by English, French, and Spanish (oh, and let's say Japanese and Chinese too for good measure).
So a single 2gb video goes from $1/yr to $10/yr, and you're not doing "the dumb simple thing" for subtitles which would basically 4x your cost over "commodity subtitling services".
Or "simplify, simplify simplify", you reduce costs (cha-ching!), and become compatible for syndication or redistribution (cha-ching!)
... and they would have gotten away with it too if it weren't for those meddling kids!
You don't need to multiply anything here, except the number of sub streams. One is ass, the other the primitive standards Netflix and other surges use.
Edit: and to the peer comment regarding S3 vs self host: regardless of 10x cloud cost, it's still 10x volume. Where 1TB local would do, now you need 10TB (10x the cost).
>Yes, it really is called ASS. Its predecessor, SubStation Alpha, went by SSA, and since these formats were developed by enthusiast hobbyists, I believe they couldn’t resist the siren song of a little bit of cheeky naming.
