HEVC at 12 Mbps achieves higher fidelity than AVC at 25 Mbps, effectively "shrinking" the required storage by more than half while improving quality metrics.
Before compressing video, look at what else is on the disc. shrinking bd25
When burning a 24.9 GB ISO image to a BD25, users experience "disc full" errors despite the nominal capacity. The practical maximum for reliable burning is for consumer drives—a physical shrink of 1.2%. HEVC at 12 Mbps achieves higher fidelity than
Understanding both phenomena is critical for long-term archiving, as overestimating disc capacity leads to coasters (failed burns), while inefficient compression degrades future playback quality. shrinking bd25
