Google temporarily disabled YouTube's advanced captions without warning
YouTubers have been increasingly frustrated with Google's management of the platform, with disinformation welcomed back and an aggressive push for more AI (except where Google doesn't like it). So it's no surprise that creators have been up in arms over the suspicious removal of YouTube's advanced SRV3 caption format. You don't have to worry too much just yet—Google says this is only temporary, and it's working on a fix for the underlying bug.
Google added support for this custom subtitle format around 2018, giving creators more customization options than regular users get with traditional captions. SRV3 (also known as YTT or YouTube Timed Text) allows for custom colors, transparency, animations, fonts, and precise positioning in videos. Uploaders using this format can color-code and position captions to help separate multiple speakers, create sing-along animations, or style them to match the video.
Over the last several days, creators who've become accustomed to this level of control have been dismayed to see that YouTube is no longer accepting videos with this Google-created format. Many worried Google had ditched the format entirely, which could be problematic for all those previously uploaded videos.
