We have premiered my last feature film on the 45th IFF in Hof. In all theatres it showed some jitter in the credits in a way that it was very hard to read them at all. In my eyes the speed could be a problem. The fonts were large enough and on an HD monitor all was good. It occurs to me that in the theatre problems arise due to the fact that the picture rate is 24 fps. We projected 1920 x 1080, 1.78x1, cropped to 1.85x1. All titles were made in After Effects, then put out to DPX. The postpro needed all DPX converted into TIF and then converted into the DCP stream. So there might be a problem as well.

I wonder if there is any rule of thumb on how fast scrolling can go before problems arise. As for instance 20 lines per second or so. Also font size might have been an issue. Also I guess converting from DPX to TIF could be a problem as well.

I would greatly appreciate any help as we are seeing forward screening in other festivals as well.
