TLDR: Google’s advanced generative video model, Veo 3, is facing significant challenges with its subtitle generation capabilities. Users report that the AI frequently adds unwanted, garbled, or inaccurate captions to videos, even when explicitly instructed not to, impacting the quality of generated content.
Google’s cutting-edge generative video model, Veo 3, launched in May 2025, is reportedly experiencing widespread issues with its subtitle generation feature. Despite its advanced capabilities in producing high-quality, audio-synced video clips from text prompts, a recurring problem has emerged where the AI either appends unwanted subtitles or generates captions that are inaccurate, poorly spelled, or nonsensical.
Reports from users indicate that approximately 70% of videos generated by Veo 3 include these problematic subtitles. This issue persists even when users employ ‘negative prompts’ or specific instructions to prevent text overlays. The problem manifests in two primary ways: subtitles appearing unexpectedly, or expected subtitles being incorrect or badly formatted. Some users have also noted instances where sound is missing or inconsistent alongside these subtitle issues.
Experts suggest that Veo 3’s training data, likely containing numerous videos with ‘baked-in’ subtitles, might contribute to its tendency to automatically generate them. Furthermore, the model can misinterpret prompt structures, especially when actions are interspersed with dialogue, leading to garbled or misplaced captions.
In response to these challenges, the user community and various platforms have proposed several workarounds. Prompt engineering strategies include explicitly defining the video’s aspect ratio, using precise negative terms like ‘without subtitles’ or ‘without text’ at the end of prompts, and clearly separating actions from dialogue by frontloading actions. For desired dialogue, it’s recommended to place speech after a colon rather than in quotes (e.g., ‘A guy says: My name is Ben’). Some users even resort to repeating ‘No subtitles. No subtitles!’ multiple times in their prompts to emphasize the instruction.
Beyond prompt adjustments, post-generation editing is becoming a common practice. Users are turning to dedicated automatic subtitle generators to create accurate captions after the video is produced, allowing for greater control and customization. Additionally, video editing software like CapCut or HitPaw VikPea are being utilized to manually crop out or remove unwanted subtitle areas from the generated videos.
