Clean Subtitles, Flawless Data
Data quality is non-negotiable for LLM training and academic research. Learn the professional method to remove timestamps and ASR noise for truly pristine text data.
The Pitfall of Raw SRT/VTT Files
Standard subtitle files are poison for high-stakes projects. Feeding noisy data into your LLM or research model doesn't just lower quality—it actively compromises your results.
How Raw Data Corrupts Your Work:
-
Timestamps & Tags: Useless structural data that confuses models and requires tedious pre-processing.
-
ASR Noise: Filler words like "um," "uh," and non-speech tags like `[Applause]` pollute semantic meaning.
-
Inconsistent Formatting: Different videos produce varied outputs, creating a data-wrangling nightmare.
How Our "Clean Mode" Works
Our engine goes beyond simple find-and-replace. It uses a multi-stage parser to surgically remove noise and deliver pure, high-quality text.
1. Structural Tag Elimination
Precisely strips away all SRT/VTT timecodes, sequence numbers, and formatting tags without affecting the core text.
2. ASR Noise Filtering
Identifies and removes common Automatic Speech Recognition artifacts like `[Music]` or `[Applause]` tags.
3. Format Unification
Consolidates all text fragments into a single, continuous paragraph, ready for any text processor or model.
