About interlaced...I know that this subject is beaten to death, but....

the treatment you're giving it seems alright to me. btw, the width doesn't really need to be 1:1 - just so long as your playback equipment can output it at the right ratio for your TV. the real thing to worry about is vertical scaling, as this destroys the interlace lines (unless you smart-bob first, then re-interlace, but usually that's a waste of time). of course with capturing there's not much reason to cap at 720 unless your destination is DVD - certainly you wont really get anything extra out of the signal, as broadcast TV is nowhere near even 640 lines.

Do NOT capture analogue video using YV12 compression. It will destroy chroma movement, because most YV12-Codecs will only downsample progressively.

I see...well, thanks for the tip. So I will just use huffyuv and "converttoyv12(interlaced=true)". (cool avatar you have, how you did this interlaced effect ?)

why do you want to go to YV12? stay as long as possible in YUY2 chroma. let the encoder do the chroma-subsampling from yuy2 to yv12. I made that interlacing effect of my avatar using AVISYnth.

Well, I want to go to YV12 because 2 or 3 filters that I'm using only support YV12.

acrespo No, there - if you hopefully set to interlaced encoding - you won't get chroma stutter. but with normal lossless YV12 codec, you'll get chroma stutter on interlaced video, because they are subsampling progressively!

Damn, the quality leaving the video interlaced is much worse than when I de-interlace it. So, I guess that I will just try to performace a IVTC or something like that. Hey, scharfis_brain! Let me please ask you a question: I'm trying to understand what kind of source I have. It's NTSC Cartoon captured from TV, so it's telecined. When the camera is fixed and only the characters move, I always see a repeating pattern of 4 clean frames followed by 1 interlaced frame. But, when the camera is scrolling vertically or horizontally, I see 3 clean frames followed by 2 interlaced frames (3:2 pulldown I think). So, I wonder what I need to consider to treat the video. If it really is 3:2 pulldown, if just a IVTC will do the job, etc Thank you...

jep, then IVTC will do the job! you have the PPPPI - Pattern on animated characters, cause they are animated at 12fps or even lower fps (eg: 8 or 6 fps) so your first step has to be IVTC. do your filtering afterwards.

I always had a doubt but not ask before. When I do a IVTC the result video is totaly deinterlace? I am asking because when I do IVTC I always have combs and need to apply a deinterlace method as post processing. TIVTC + PP=7 for example.

I am asking because when I do IVTC I always have combs then, you video is not telecined Film.
