Since the flash is firing thousands of times the individual flashes are several stops lower in power than in the normal flash mode.
Firing this much means that all parts of the image are recorded since some light is present at all points of travel of the shutter slit. HSS causes the hot-shoe flash to fire thousands of times during the time it takes for the shutters to travel. High Speed Sync only works with hot-shoe flash units that are capable of HSS. Hot-shoe flash units have a different type of discharge circuit and their flash duration increases as the power increases, but is still so short that SuperSync or HyperSync usually doesn't work. Unfortunately with most studio strobes the flash duration decreases as the power increases and if you use SuperSync or HyperSync you need more flash power. SuperSync or HyperSync works well with many studio strobes units since their flash duration is usually longer than that of hot-shoe flash units. You will expose all the image but only a slice of the light output by the flash will be used and the exposure will have to be increased compared to what it would be if a shutter speed equal to or less than the sync speed were used. With SuperSync or HyperSync the flash only fires one time but if the flash duration is long enough the camera shutter can open and close at a shutter speed higher than the sync speed while the flash is still on. If you fire a single flash when the shutter speed is shorter than the sync speed normally part of the image will not be exposed, you will get a black bar, and underexposed area, across part of the image. The result is a shutter slit traveling across the image sensor. This is why a single flash can expose the entire image.Ībove the sync speed the second shutter starts to travel before the first shutter finishes its travel. When you shoot at the sync speed or lower the first shutter opens fully before the second shutter starts to travel. SuperSync or HyperSync is not the same as High Speed Sync. Features: 1, 3 Groups ( A/B/C) 5, Trigger Interface: Hot shoe, PC. Just last night I was syncing my 5D at 1/8000s with my Jinbei Freelander II. This product is a wireless transceiver design, the distance of remote control reaches 100M, supporting 7 wireless channels and A/B/C three groups, and with AF assist beam emitter function. Ironically cheap flashes have longer duration and work best with this. First curtain, Second Curtain and Fast Shutter (Supersync) syncs are.

I have the 622 and its has a feature called SuperSync which works with flashes that have long tail (duration). Yongnuo YN-622C Manual Online: on-top flash, Pc-Sync Flash, Factory Reset.
