Why Use OCR to Extract Video Subtitles?

Video subtitle extraction is the process of converting the subtitles in a video into SRT. The traditional method is to use automatic speech recognition (ASR) technology, but for some types of videos, such as short films, OCR technology can provide higher accuracy.

OCR technology has the following advantages:

• Higher accuracy: OCR can directly recognize the text in the video frames, and is not affected by audio quality. Therefore, for videos with noisy environments or low-quality audio sources, OCR can provide higher accuracy.
• Stronger robustness: OCR can recognize multiple languages and fonts, and can accurately recognize accents and dialects. It is also not affected by background music and other noise.
• Higher efficiency: OCR can process videos faster because it does not need to convert audio to text.

Here are some scenarios where OCR technology can be used to extract video subtitles:

• Extract subtitles from videos without audio tracks
• Extract subtitles from videos with poor audio quality
• Extract subtitles from multilingual or dialectal videos
• Extract subtitles from videos with a lot of background sound or noise
