Question (sorry if this has been asked before)...interlacing

[atrophiedXlungs]

Ok, I've been reading the FAQ's and learning a lot of things I didn't know before. I've come to understand that interlaced footage is bad if you plan on releasing a video for play on computers, or if your video's widescreen and you're entering it in a con...as you'll (likely) have to vertically resize.

I also read that removing interlacing after making the video leads to problems and tends to be imperfect. Now, I use AVISynth to create...so I was thinking, would it be possible to just make a parallel script, removing the interlacing from the clips used?

Like:

Code: Select all

avisource(d:\whatever.avi)
Telecide(order=1,guide=1)
Decimate(cycle=5, mode=2)
something1 = trim(blah, blah)
...
somethingvid = something1 + something2 ...
return somethingvid

(or something like that, you know)

Ok...thanks. [/code]

Well, since you included that Decimate line, you'd have to adjust the parameters of all your Trim()s to account for the lower framecount. (If you want to avoid this and keep everything at 29.97, you can either use Telecide <i>without</i> Decimate, or use a deinterlacer like TomsMoComp.)
Also, it's possible that a simple IVTC might not work on your source, in which case you'd have to find some other deinterlacing solution.

Ok, I see what you're saying on both counts (and I thought of the fact that an IVTC might not work), I really just wanted to know if it'd technically work that way. Thank you. =)
