Random but persistent flicker – IoHD

[Gary Adcock]

[Jim Randall] “The host names appears at the first and the last of the segment (the same file) and is steady. The other two, also shown twice in the segment using the same file causes the picture behind the super to flicker vertically. It will ALWAYS flicker on these two files. “

OK

that right there leads me to think that it is your file and not the IoHD, since this is not happening on all of the L3’s just a couple- I has to be something with the way that those files are created.

have you tried them in a new seq with no footage / different footage behind them?

have you looked at other tools.

have you FULLY RENDERED the file out before playback?

[Jim Randall] “Playing the program on the computer does not give any hint there is a problem. I see it when it passes through the ioHD into the HDTV studio switcher”

you are sure it is not your graphics?

Thanksa for the tips. I render the final FC timeline before I export it to QuickTime movie. This seems to have fixed the problem.

I had this exact same problem when working in 1080i. I tried 3 different Io HD boxes, chaneged driver software, changed firewire cables and ports with no success. Later had the same problem on a brand new Mac Pro. I set my field dominace to NONE and the flicker stoped. It does make some of the livetype graphics a touch blury becuase they are inteneded to be interlaced but thats a better option than the video shifting.
