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 too am having a flicker with playback with the ioHD. However, I can replicate the problem when it happens. It ALWAYS happens with a lower third super (made with LiveType.) In this last project the segment had six lower thirds in one five-minute segment.

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.

The lower thirds are made using the same “master template” as the other dozen or so lower thirds in the program. They are all steady.

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. I see it on ioHO control monitor. The program is produced in 1920 X 1080i.

This problem occurs somewhere in every program I have produced using the ioHD. We have switched the ioHD’s with a brand new unit. It is the same result.

It does not matter if the clip the lower third is over was up converted from 1440 X 1080i or a native 1920 1080i.

I’m using Apple ProRes 422 1920 X 10801 (HQ).

I have exported the program out to a QuickTime movie and played it back. Same result in the same place! I have played it back from the original sequence time line (rendered) same result.

I tried switching the FW from the back of the MAC Pro to the front as suggested. Problem still there, and occurs with same two files, in the same place. I have even run the program on a different computer use a different ioHD!

The program and running on our Apple SANS network.
