Improving Video Performance for Single-Threaded Codecs

Sometimes, video problems, such as stutters during playback, are caused by codecs that do not support multi-threading. This can be the case for video files that use single-threaded decoding, such as Motion-JPEG, Photo-JPEG, and DV codecs. These types of video files are typically created when capturing video with Decklink cards by Blackmagic Design or cards by AJA.

To compensate for this, you can activate the “Boost Video (Reduces Audio Performance)” option on the Video Player page in the Device Setup dialog. This excludes one of the available CPU cores from audio processing and reserves it for video tasks like decoding and playback. However, this may reduce the audio performance.
