X265 - Alarum

| Feature | x264 (H.264/AVC) | Alarum x265 (H.265/HEVC) | | :--- | :--- | :--- | | | Baseline standard. | ~40-50% bitrate reduction at equivalent quality. | | Max Resolution | Efficient up to 1080p. | Native optimization for 4K, 8K, and HDR . | | Encoding Speed | Very fast; low CPU overhead. | Slower; significantly higher CPU load . | | Hardware Support | Universal support (decoders). | High support on modern devices; issues on legacy hardware. | | Latency | Lower encoding latency. | Higher latency (dependent on presets). |

Many mainstream x265 encodes either over-filter or use fast presets, causing blocking, banding, or waxy skin tones. Alarum x265 aims for the sweet spot: alarum x265

x265 includes native support for High Dynamic Range (HDR) and Wide Color Gamut (WCG) metadata (SMPTE ST 2086, MaxFALL, MaxCLL). This ensures that the video pipeline is future-proofed for high-fidelity visual standards. | Feature | x264 (H
