25 frames per second picture jitters at DVinfo.net

Hello,
I recogniced that in 25 frames mode the picture is very unstable if you make fast moves from left to right. If you watch this moves on an ordinary TV-Set the picture jitters like a strobelight. Am I doing something wrong? Please help.

Yes you are doing something wrong: "fast moves from left to right"

It has been known for a long long time in the film world that you
should not do fast moves (unless fast enough to blur out). Also
some angles will produce these problems more often than others.

It is one of the issues of lower framerates and shutter speeds etc.

Same principle applies for the NTSC version at 24p.
