OBS Studio 28.1.0 正式版 重大更新 建议升级

28.1 主要更新内容：

在Windows上添加了NVENCAV1硬件编码器

目前仅适用于NV12（OBS默认）和P010颜色格式

当前不支持高级输出模式下的“重新缩放”功能

仅适用于NVIDIA的RTX 40系列视频卡

更新的NVENC预设

预设分为三种不同的设置：预设、调谐和多通道模式

预设现在是P1-P7，数字越低质量越低，数字越高质量越高。请注意，较高的预设可能会导致较高的GPU使用率，这可能会影响与OBS同时运行的游戏的性能。当使用最高的预设时，同时NVENC编码会话的数量可能会更低。升级时，OBS将自动将您当前的NVENC设置映射到最接近的预设。

调整用于确定是优先考虑延迟还是优先考虑质量。它有三种设置：高质量、低延迟和超低延迟。

多遍模式用于确定是否在编码中使用第二遍，并有三种设置：禁用、四分之一分辨率和全分辨率。启用此功能将以更多GPU资源使用为代价提供更高的质量。

修复了Direct3D 9游戏在Windows 11 22H2上停止正确捕获游戏的错误

修正了设置亮度擦除和缩放过滤时视频捕获变暗的情况

28.1 Changes

• Added NVENC AV1 hardware encoder on Windows [Jim]
  • Currently only works with the NV12 (OBS default) and P010 color formats
  • Currently does not support the "rescale" feature in advanced output mode
  • Only available for RTX 40 Series video cards from NVIDIA
• Updated NVENC presets [Jim]
  • Presets have been split into 3 different settings: Preset, Tuning, and Multipass mode
  • Presets are now P1-P7, lower numbers being lower quality, higher numbers being higher quality. Note that higher presets may incur higher GPU usage which could impact the performance of games running simultaneously with OBS. The number of simultaneous NVENC encoding sessions may be lower when using the highest presets. OBS will automatically map your current NVENC settings to the closest preset when upgrading.
  • Tuning is used to determine whether to prioritize latency or quality. It has three settings: High Quality, Low Latency, and Ultra Low Latency.
  • Multipass Mode is used to determine whether a second pass is used in encoding, and has three settings: Disabled, Quarter Resolution, and Full Resolution. Enabling this will give higher quality at the cost of more GPU resource usage.
• Fixed a bug where Direct3D 9 games stopped capturing properly with game capture on Windows 11 22H2 [Rodney]
• Moved "Always on Top" to the View menu [gxalpha]
• You can now select a specific source for the Virtual Camera [chippydip]
• Fixed a crash on resolution change of Windows Virtual Camera [Jim]
• Fixed a Discord crash with Windows Virtual Camera [Jim]
• Fixed crashes with macOS applications loading the virtual camera [PatTheMav]
• Fixed Steam version launching x86_64 version on Apple Silicon devices [Rodney]
• Fixed Stats widget appearance issues [tytan652]
• Fixed Blend Method in Studio Mode [rcdrone]
• Fixed case where video capture is darkened when both luma wipe and scale filtering are set [rcdrone]
