encoding partial IVTC / interlaced

Hi- I'm using Decomb500b16. You might have to adjust the settings if you're using a different version. I'd try mode 3 to see if it works for you. That will IVTC the telecined portions normally and do blending on the interlaced portions to make them also 23.976fps. So it should wind up similar to what you envisioned. It should be a definite improvement over the .avi you provided, but maybe not perfect. So, try some variation of this: Telecide(Order=1,guide=1) Decimate(mode=3,threshold=1.0) Order=1 refers to Top Field First. You have to set the field order in recent versions of Decomb. See the Decomb docs for more information.

thanks much for the info guys. i hate to say it, but i have no clue how to use an external filter with gordian. is there a quick primer guide out there that will get me going? then i can try what manono has suggested... thanks again Al

Hi- I think the version of Decomb included with GKnot is 410b4. To use Mode 3 in that version, you might try: Telecide(guide=1,gthresh=30) Decimate(mode=3,threshold=1.0) But recently he has changed and improved the Mode 3. If you want to try Decomb500b16, you can get it . Rename the .dll as Decomb.dll and replace the one in the Gordian Knot folder with it, making sure to save the included one in case you want to go back to it. But this isn't an external filter (it's external to AviSynth, but not to GKnot). Decomb410b comes with GKnot. It's the default IVTC. All you have to do is to edit the script. You make sure the Decomb.dll is loaded (LoadPlugin("decomb.dll")), and then open and edit the Telecide/Decimate lines. And read and study the Decomb docs. Working with that hybrid material requires some skill. Just ask Nel. It almost drove him nuts. :)

Hi- You've got me stumped with that softness along the right side. I was going to suggest next that you make both the left and right crops multiples of four, but evidently you tried: crop(20,0,688,480) BilinearResize(544,416), and if true, then the left crop is 20, and the right crop is 12. So that's not the answer. About all I can suggest now is to try the latest Decomb5 (Decomb500b16). I gave the link above. But some of the parameters change, and you can use the script I gave earlier as a starting point. And read the doc for further help. Here's some other things to try. Try a bicubic resizer and see if that helps. How are you determining that it's soft on the right side? Just by looking in VDubMod? By looking at the finished .avi in your player? Have you tried a different player (maybe try the BS Player)? What codec are you using and what are you using for decoding. If DivX5 with the DivX decoder, you might install and try . The reason I mention it is that improper crop values can do some nasty things, like the infamous green line along the side, but your problem is new to me, and you seem to be doing everything right. Maybe some others have seen the problem and can help out. Let us know how it goes. Edit: I was thinking some more about this later on. Are you using any other filters (such as smoothers/denoisers) besides Crop, Resize, Telecide, and Decimate? Sometimes they can cause conflicts and/or require different crop parameters. If so, try and comment them out (put "#" in front) temporarily and see if it makes a difference. Also, maybe you can post the .avs (leaving out the lines beginning with "#") so I can try and duplicate the problem.
