When starting playback in Premiere Pro, there may be a single digit number of dropped frames after which there should be no more drops. Large numbers of dropped frames can be indicative of networking issues, workstation issues, or storage performance.
During the initial phase of playback Premiere Pro tries to fill up its InQueue and CPU FramesCompeteAheadOfPlay buffers. During this time, the FramePrefetchLatency number will be in the hundreds of milliseconds. Once the two buffers are full (just over 300 frames), the FramePrefetchLatency should drop down. That latency metric can be as low as 20 to 30 milliseconds but on busy production systems may be as high as 200 millisecond.
Sometimes, even when Premiere Pro is not dropping frames, neither the InQueue nor the CPU FramesCompleteAheadOfPlay buffers can fill. In this case, the FramePrefetchLatency will remain high. In this state, Premiere Pro playback may be unstable. The application may not be responsive to starts, stops, and timeline scrubbing.
If possible, stop other traffic on the storage system and begin playback on a single workstation. If playback is fine and latency healthy, add workstations or other load until playback is negatively impacted. This behavior can indicate the limits of the network or storage.
