<p>I'm a little confused. I know that regular 24fps video for the 5D MarkIII at 1920x1080, requires a shutter speed of 1/50.<br>

If I'm shooting video at 1280x720 at 60fps for slow motion when I edit in Premiere Pro, what is the optimum shutter speed? In searching through the net, I can't seem to get a firm answer on that.</p>

<p>I put the YN622 controller on my Nikon D7000 and immediately I could see the aperture change on the flash as I adjusted it on the camera. But there was still no noticeable control of the flash from the controller. I put the flash on iTTL and still got nothing. I'll do some more tests and see if I can figure it out.</p>

<p>Just purchased a Yongnuo YN568EX flash, YN622N-TX controller and two YN-622N transceivers. The whole purpose was to have an off camera speedlight I can control entirely from camera position, as well as having high speed sync. So far, I can fire the flash remotely using the the 622N-TX controller and one of the 622N transceivers, but I can't make adjustments to the flash from the controller position. At this point, all I have is a remote trigger and if I want to make adjustments to the flash output, I have to do it manually on the flash.<br>

I've pulled up every Youtube tutorial I can find and have done my best to decipher the Chinese to English owners manuals and I haven't been able to control the flash with the controller, except for basic firing. At the moment, I'm not putting the controller on the camera. I would think that I don't have to have the controller on the camera for everything to work.<br>

Can someone give me some pointers on this. Wanting to use this speedlight/trigger combination over the weekend and would like to not have to adjust everything at the flash.</p>
