What Bitrate Actually Means for Viewing
Below 12 Mbps at 4K, macro-blocking artifacts become visible in high-motion scenes — fast editing cuts, kinetic sequences, compression visible in hair and fabric. Above 20 Mbps, the stream holds detail cleanly even on a 65"+ OLED panel at full brightness. The difference is immediately visible when streamed side-by-side.
