本文將深入說明 Adobe Premiere Pro 和 Adobe Media Encoder 的 Mercury Playback Engine (GPU Accelerated) 與硬體解碼 / 編碼。
Mercury Playback Engine (GPU Accelerated) 演算器
Adobe Premiere Pro 和 Adobe Media Encoder 能夠運用系統中可用的 GPU 來分散 CPU 及 GPU 之間的處理負載,藉此提高效能。目前而言,多數處理工作多是經由 CPU 執行,而 GPU 則只協助處理特定工作與功能。
硬體加速解碼和編碼
Premiere Pro 支援硬體加速編碼,以加快編碼 (匯出) 效能並減少匯出 H.264 和 H.265 (HEVC) 格式的時間。 Premiere Pro 還能加速對 H.264 和 H.265 格式硬體解碼的支援,來提高時間軸播放效能。
使用這些功能需具備有硬體加速編碼和解碼功能的 GPU。
檢視資訊以了解您的 GPU 是否支援硬體加速解碼和編碼。
Apple silicon (M1 以上版本) 支援 H.264 和 H.265 格式的硬體加速解碼和編碼,包括 10 位元 4:2:2 解碼支援。 HEVC HLG 4:2:0 10 位元編碼仍需透過軟體進行編碼。
以下為硬體加速編碼和解碼的系統需求資訊。
硬體加速編碼支援
在「Export Settings」的「Format」下拉選單中,選取「H.264/HEVC」以啟用該選項。 接著在「Video」標籤下,前往「Encoding Settings」,然後將「Performance」設為「Hardware Encoding」。
支援的轉碼器平台
編碼:H.264/AVC (8 位元),HEVC 4:2:0 (8 位元和 10 位員),可高達 4096x4096。 如搭配第 10 代與更新版本的 Intel® Core™ 處理器,HEVC 編碼支援可高達 8192x8192。
硬體加速解碼支援
Adobe Premiere Pro 和硬體加速編碼一樣也支援硬體加速解碼,可以在處理時間軸上的 H.264/AVC、HEVC 媒體時提高播放效能。
啟用硬體加速解碼的步驟:
-
-
選取「Enable hardware accelerated decoding (requires restart)」。
-
重新啟動 Adobe Premiere Pro.
支援的轉碼器平台
此功能專用於處理 H.264/AVC 和 HEVC 轉碼器的 MP4 媒體。Premiere Pro、Adobe Media Encoder 和 After Effects 22.0 版及更新版本均支援在 Intel 平台上使用 HEVC 4:2:2 10 位元硬體加速解碼功能。
M2TS (MPEG-2 傳輸資料流) 不受支援。如果您使用 4K M2TS 媒體,則將該媒體轉碼至可接受支援的 MP4 轉碼器,可能有助於提高播放效能,因為經轉碼的 MP4 媒體能夠使硬體加速解碼發揮功能 (如果轉碼 HD M2TS 媒體,效能增益可能不明顯)。
在搭載 8GB 或更低 RAM 的整合 Intel® GPU 上處理硬體加速解碼,效能可能受限,且由於整合 GPU 將 RAM 當作共用 GPU 記憶體,可能導致 CPU 接管處理作業。建議使用 16GB 或以上的 RAM,才能取得更佳效能。
硬體加速解碼、Mercury Playbck Engine (GPU Acceleration) 與硬體加速編碼間的差異
- Mercury Playback Engine (GPU Accelerated) 是用於處理 GPU 加速效果的演算器,可加強播放功能。
- 硬體加速編碼功能可在轉存 H.264/AVC 和 HEVC 轉碼器上的時間軸時加速編碼效能。
- 硬體加速解碼則是在播放時間軸時用於加速解碼 H.264/AVC 與 HEVC 媒體的程序。
