I've a video via FireWire in iMovie imported. When playing of the individual clips to me the picture is not very liquid before but this is not really the problem. Especially when you export to another format (MPEG4 or H.264), I have these lines in artifacts movements. The best you can see this when you quickly with the hands herumfuchtelt. Because I not only double but holding hands synonymous these lines. Maybe I have some stupid beginner mistake but I can not thing what ...
How many FPS this cam anyway? only 25? And is 1049 x 576 resolution really? What settings do you have to import with the highest quality? 29 FPS should I adjust?

Unfortunately, this is perfectly normal, thank you for the antediluvian video technology, which unfortunately are still considered "standard" applies to "Television" in order to cope. The magic word is "interlaced" (contrary would be "progressive"), ie the video image is split into two fields, one each for every 2nd Image line. This reduced amount of data can then be synonymous handle a conventional television.
In a second are 50igstel eg all the odd scan lines rewritten in the next 50igstel seconds all straight lines, etc. If you now as your hand quickly move through the picture, it is in a 50igstel seconds but weitergewandert, and the even and odd lines no longer fit together, which gives the infamous Kammeffekt with supposedly two hands - that is what you notice. A conventional television is so bad and blurred, such that you can not see cheating, but on a computer monitor's cruel from.
Professional programs like Final Cut Pro so called "De-Interlace" who try, from the two fields is a coherent whole aggregate. How well you always synonymous but does it always focus and information to a certain extent lost. Really can avoid the problem only by using a high-quality video, in addition to "interlaced" synonymous "progressive" dominates.
With an amateur program like iMovie you need to you with the interlace effects resign. The only consolation: if you cut your movie into iDVD with DVD format exportierst (synonymous if you have no DVD burning, but the files on the hard drive is) and then you with the DVD player of Mac OS X on a new and powerful Mac anschaust, then you can use the DVD player a de-interlace function for playback on, the problem should at least lessen.
I hope this helps you next.
