HDV Flicker caused by Strobe light, Help needed :)
Posted 16 January 2008 - 05:57 PM
I was working on a music video as a gaffer as part of my course, and we wanted to shoot a scene in a nightclub, utilising a strobe light. We were shooting on HDV, through a Movietube LT with Nikon Nikkor lenses. We shot with 9db gain, at 1/25th Shutter and used a Zenin 400w Strobe light. You could desribe the effect as a scrolling scan line which went from top to bottom gradually.
Does any body know what this is and or how to fix it if not prevent it from happening again? Comments and suggestions appreciated.

Basically the only way around it is to make sure that the flash duration is longer than the shutterspeed.

I guess we need to know camera setting and strobe setting to know for sure. I would imagine you should have seen it in the viewfinder, and could have adjusted either the shutter or the strobe rate to correct it, doesn't sound like something that can be corrected in post tho.
