Right, so I was sent out the other week to film a little video for work at this simulator place (it was pretty awesome) BUT they were using a combination of LED monitors and LCD large screen Samsung TVs.
No matter what i tried I could not get around the screen flicker coming from the TVs. I checked the on screen display and it said that the refresh rate was 60hz. I tried every setup combination i could think of (I thought 1/60th at 30fps would have worked but it didn't) I've uploaded a little clip -
*I should probably add i was shooting on a MKII and a 550 running Magic Lantern.
