Accuracy Improvement Program
The following optimization strategies can be adopted for different analysis requirements:
- Model Selection: Choose the right size Whisper model (tiny to large) for your needs, larger models provide higher transcription accuracy.
- Keyframe Settings: Increase the value of the -frames-per-minute parameter (e.g. 30fpm) for a more comprehensive visual analysis.
- Multi-model validation: Cross-validation in conjunction with the use of the Ollama Vision model
- reprocess: Manual validation of the generated JSON results to correct obvious errors
- Environment Configuration: Ensure FFmpeg version compatibility to avoid codec problems affecting input quality
Special note: For videos in specialized fields, it is recommended to prepare a glossary of field terms in advance, which can significantly improve the quality of the transcription.
