Two‑Pass Deep Learning Bitrate Factor Prediction for Constant‑Quality Segment Encoding in Bilibili Narrow‑Band HD Transcoding
Bilibili’s IEEE‑VCIP‑2022‑accepted two‑pass deep‑learning bitrate‑factor predictor achieves 98.8% accuracy with only 1.55 encoding passes, enabling constant‑quality segment encoding that reduces bitrate consumption by over 15% while maintaining visual quality in its narrow‑band HD transcoding pipeline.
