Unverified不含硬件编码器，所有编码压力由电脑CPU/GPU承担，CPU性能偏弱的电脑在4K60采集时可能卡顿或录制质量受限74% similarUnverified需要硬解4K HEVC或Plex转码，必须选带核显的Intel Celeron/N系列处理器（如J4125、N100）；ARM架构机型（如瑞昱、Marvell）通常不支持实时转码，Jellyfin/Plex会用CPU软解导致卡顿73% similarUnverified硬件编码(NVENC/AMF/QuickSync)性能占用极低但同码率下画质略逊于软件x264编码；追求最高画质且CPU强劲选软件编码，追求低占用选硬件编码72% similarUnverified软件解码的 CPU 占用可能是硬件加速路径的 5 到 10 倍72% similarUnverifiedCPU核心数与单核频率的权衡：核心多利于渲染/编码但单核弱会拖累剪辑时间线预览流畅度，剪辑为主选高频中核，渲染为主选多核72% similar
