Clean and fix SRT/VTT subtitle files programmatically

Subtitle files are an essential part of audio and video content, providing crucial information about the timing and text associated with audio events. However, in the fast-paced world of media creation and distribution, subtitle files can easily become corrupted or broken during processing, storage, or transmission. This can result in poor-quality subtitles that fail to accurately display the intended text.

SRT (SubRip Subtitle) and VTT (WebVTT) are two popular subtitle formats used across various platforms. While they share some similarities, each has its own strengths and weaknesses. Despite their popularity, SRT/VTT files can become messy due to various reasons such as encoding errors, formatting inconsistencies, or simply being too large for efficient storage.

Repairing broken model JSON is also a common issue in AI-powered applications, which can lead to incorrect or incomplete subtitle data. In such cases, having a reliable tool to clean and fix SRT/VTT subtitle files programmatically would be incredibly valuable.
