YouTube's SRV3 Captions Bug: Creators Frustrated

YouTube creators are experiencing significant frustration due to the temporary disabling of the advanced SRV3 caption format. This custom subtitle format, introduced around 2018, offered creators granular control over caption appearance, including colors, transparency, animations, fonts, and positioning.

These advanced features allowed for sophisticated captioning, such as color-coding dialogue for multiple speakers or creating animated sing-along lyrics. Many creators relied on SRV3 for its enhanced customization capabilities, which are not replicated by standard AI-generated captions.

Google has acknowledged a bug that may break video playback for some users, leading to the current limitation on SRV3 caption serving. While the company assures that support for SRV3 is not entirely removed, new uploads in this format are blocked, and existing videos may not display captions.
