Sorry Kionon, 'cut (me) down' was probably the wrong expression, i have some difficulties in knowing when such an expression is used, I guess it was too 'strong' in this aspect. Also I didn't really mean it in a negative way, since you were right in everything you said. Actually I was refering to the very first time I talked to you over a year ago when I was asking some really stupid questions ^^
Anyway, it is sometimes hard to guess the mood of someone you don't see or hear talk, since your answer was kept pretty shortly (even though everything was said I guess) I got the wrong impression.
Either way, I am grateful for your help. Since I will be on vacation again starting the day after tomorrow and the premiere date is on friday as well, I won't have the time to do it via avisynth and download all the programs.
However, I tried the method Bauzi mentioned on both of the videos. It worked perfectly for one, the other one isn't affected at all but the interlacing isn't that grave... I am gonna go over all these guides again once I have some more time.
Thanks again.
Oh and by the way on a different matter:
Does it have any disadvantages to use mkv files directly in Final Cut? My external harddrive is stuffed so I can't convert to Huffy and on top of that the DVD's won't come out in Europe or the US apparently. Anyway, I was experimenting a while ago with some textless mkv openings and found out I can use them in FC.
So I used MkvMerge to demux the mkv files and could now import the video file to FC without even having to change the container.
It worked pretty smoothly but now I just wondered if there is any disadvantage in doing so. Like, for example, what exactly is the advantage of Huffies, apart from them being lossless in conversion? is the quality of avi's or other non-lossless (? eh yeah) codecs reduced when applying effects? Also I encountered a really strange problem. I had no problem with any mkv file at all, except the one I need to use really badly. lol
Um, yes, Kara no Kyoukai:

Original file. Flawless.

I could cry just as her when seeing this... *shivers* The quality is... beyond words. It's already like that when importing to FC.
I think the difference is visible. As I said, this is the one any only case I have had this happen. As far as I can tell it is even encoded the same way. Could it be the lenght of the video? It is almost 2 hours long.
Well, I will experiment a bit more but I thought maybe one of you has some experience with that.
