Enhanced Audio and Video Synchronization¶
Enhanced Audio and Video Synchronization provides improved full-screen video playback, reducing the difference in delays between the audio and video channels and smoothing frame playback on the client. This improves lip sync and reduces video frame drops for video playback.
This feature introduces a small lag in user interaction responsiveness when enabled. Using enhanced audio and video synchronization will reduce the maximum frame rate.
Enhanced A/V Sync is enabled on a per-display basis, so you can dedicate individual displays to playback without impacting responsiveness on the others.
To use enhanced A/V Sync:
- If you are in full-screen mode, reveal the menu bar on the display you want to enhance by moving the mouse cursor to the top of the screen.
- On the display you want to enhance select View>Enhanced A/V Sync to toggle the enhanced sync mode.
Persistent Display Topology
The Enhanced Audio and Video Synchronization feature is persistent across sessions from the same client, provided that the display topology has not changed.
PCoIP Ultra AV-Lock¶
PCoIP Ultra AV-Lock enables regulated synchronization of audio and video frames. When audio is playing the video frames will be delayed to align with the audio sound track. When there is no audio playing the video frames will be presented to the user without delay. For some use cases, such as video editorial, audio video synchronization is critical and must be tolerant of variable network conditions that may be present with remote work.
PCoIP Ultra AV-Lock enables more regulated synchronization of audio and video frames compared to Enhanced AV Sync described above. PCoIP Ultra AV-Lock is available with PCoIP Ultra CPU Offload, GPU Offload or Auto Offload. You must enable the High Performance Client mode for this feature to function correctly, for information on this, see High Performance Client.
