Well, I wouldn't say so. It depends on what you are targeting. If you 
want for instance to play the video on a TV, then you might be better 
off having 50i than 25p or 24p. I've experimented with my Panasonic 
AVCHD camcorder and I have to say that actually 50i videos look much 
smoother on TV screen, especially when panning (this is also why I don't 
like current cinema technology - 24p is simply not smooth enough for my 
eyes when panning). The only problem with interlaced material is that 
it's not completely supported through the whole tool chain. Especially 
rescaling of interlaced video makes problems.

In contrast, if you want to target PC only, 25p is better (though you 
can still deinterlace 50i).

Of course, the best would be 50p, but that's probably far in the future :-)

BTW, regarding $SUBJ: I hope that in about two weeks I will find again 
some time to look at ffmpeg support for AVCHD seeking, so that others 
can profit from editing AVCHD in kdenlive directly (I actually have it 
working on my machine already, but it's not that easy to get the patches 
to ffmpeg, as it touches too many components and is not yet inline with 
what ffmpeg people want).

Ivan
