Obviously, again what i was trying to point out was lost on those that dont take the time to actually think about what they are reading...

It has nothing to do with the IVTC function itslef, simply making use of the frames the the IVTC process discards. If u think that every discarded frame is interlaced, u are sorely mistaken. Most of them tend to be duplicates of frames that are used in the output process, without the noise on them. I dont care what avs filter u use to preform the IVTC, it will always deal out the function in a static pattern (ie: 101001) and for Danny to suggest any filter "fixes" frames that are interlaced is absolute nonsense. At BEST it will take two sequential frames and blend them together, which will always produce a sub-par frame that is as sharp as a butter knife.

If you understood what creates the problem in the 1st place (the original telecine process itself, it has nothing to do with the source being transcoded to MPEG2 as Danny seems to think) you would see that what I suggest is an excellent way to rid ureself of the noise et all in older animation.

Any filter u use will again simply try to correct the noise problem according to a static algorythm which is by no means as good as doing it with ure own eye. No noise conforms to any pattern, it is strictly random an no filter at all is intelligent enough to capture it all.

Im not going to lower myself to his level an sling bad names around, but perhaps he needs to try a bit of reading for himself to understand the cause of problems before simply suggesting people copy an paste the usage syntax for whatever filter his half-baked two second google search threw at him.

Right. So then, anyone have any idea's other than iVCTing a 43 episode series frame by frame and then photoshopping each frame?

Oh, wow, Danny had some good ideas! And look, I implimented them and they look better. Crazy huh? Yeah, I know it's crazy. But not as crazy as shakespeare. :D

HEY!!!

Shakespeare might have been a little nuts but he wrote some fine plays

Oh how convenient. A theory about God that doesn't require looking through a telescope.

Obviously you've never tried Decomb. :?

There is <b>no pattern</b> to what frames Decomb's Decimate function drops; it will simply drop the frame judged to be most similar to its predecessor in each group of five (or however many frames you set the "cycle" parameter to), unless you tell it to follow a pattern to guide the decimation -- and even then you can set a parameter to override the pattern if a frame is close enough to the previous to warrant being dropped when it originally wouldn't have been.

If you'd <i>read</i> the documentation, you would have known that.

Also, @risk: it IS possible to guide the Telecide process frame-by-frame by using an override text file. But if that's not good enough for you, have you tried <a href="http://yatta.mellbin.org/">YATTA</a> (which I have never used myself)?

You're absolutely right, I spoke too soon.

This is the first time I've heard of YATTA, but it looks very interesting. I'm not sure if I care this much about IVTC'ing correctly (especially since I live in a PAL country), but the manual is certainly worth a read.

*downloads manual and reads* *whistles appreciatively*

Wow. That's some pretty powerful stuff. Hell, the ability to apply different AVS filtering to sections with a GUI alone would probably make that worth using even without touching the potentially more powerful IVTC capabilities. I wish I'd had that for my Pro video...
