Anyone using Pocketwizard TT1 and TT5s? With on camera flash I can sync at 1/250th fine but with the radio triggers I can't sync faster than 1/180th without banding.
After some research I guess there's a latency with the radio signal getting sent to the remote flashes so you can't sync at 1/250th. Wonder how Blabac did it as loads of his photos are listed with 1/250th and flash (maybe it was just on camera flash)
Lots of variables for that lag. Could be the TT1 and TT5 interacting. Could be the cables you're using. Maybe even batteries with low life. Could be the camera combined with the pocket wizards.
There are lots of other gear combos that could get you that full 1/250th. Maybe all the same branded camera, transmitter, and flashes? Like all Nikon if that's what you shoot. Blabac could be using a whole profoto system. So transmitter and lights are the same brand.
I'm running Godox TT685II with their dedicated transmitter on a Nikon D610. I did the experiments from the Hammeke video on a blank wall. I get banding at 1/250th, BUT this flash set up has HSS (high speed sync). That's different than the hypersync talked about in that video. Flash technology has advanced quite a bit. With HSS turned on, I can shoot way faster shutter speeds without banding. I haven't tried much over 1/1000th. The downside to HSS is you lose flash power. So there's a tradeoff.
Maybe see if you can do HSS with your setup. Might not be possible with pocket wizards combined with the flashes you're using. Or look into getting those Godox speed lights. They're pretty affordable.
