HyperSync
From PocketWizard Wiki
This section only talks about HyperSync. Read the section on Understanding HyperSync and High Speed Sync to learn more.
HyperSync enables a PocketWizard connected flash to begin firing just *before* the camera triggers a sync pulse. Since you are "triggering faster than a wire" with HyperSync, you can sync at shutter speeds faster than X-sync for many cameras and get more usable flash energy before Auto FP (High Speed Sync) is activated.
HyperSync is set in a transmitting ControlTL radio only. It is not set in a remote FlexTT5. All receiving PocketWizard radios, including the Plus II, etc., will trigger in sync with HyperSync. HyperSync requires a MiniTT1 or FlexTT5 as a transmitter. A Standard transmitter like a Plus II cannot trigger a remote FlexTT5 and achieve HyperSync.
Adjusting HyperSync is done in the PocketWizard Utility. Proper adjustment is dependent on on your equipment’s abilities. Try the default setting and look for clipping (black lines in your images). Adjust up or down as needed to eliminate the black lines. It is not always possible to eliminate the black lines as the shutter speed increases.
If you are seeing Front Curtain clipping (top of frame is dark), then your HyperSync offset should be moved to the right.
If you are seeing Rear Curtain clipping (bottom of frame is dark), then your HyperSync offset should be moved to the left.
When making adjustments, try adjusting in 30 microsecond steps until you see some changes, then try smaller steps to fine tune your setting. Remember to press Apply Settings in the Utility after every adjustment.
For some camera and flash combinations it is not possible to eliminate clipping, especially at the faster HyperSync shutter speeds like 1/400 and 1/500. Use a slower shutter speed or set "High Speed Sync (HSS/FP) Begins At:" on the Sync Timing Tab to a lower shutter speed.
Canon Note: If you have a flash in the shoe of the MiniTT1 or FlexTT5 on your camera, it must be set to High Speed Sync (FP Flash). If not, the camera will be limited to a 1/200 shutter speed and will not use HyperSync. If there is no flash in the shoe of the MiniTT1 or FlexTT5 on your camera, HyperSync and High Speed Sync will be used automatically with your remote flashes.
