IVTC problems with 1080i
It seems that no matter what decomb settings I try there are a few jerky scenes. I have tried the normal Telecide(guide=1) and decimate(cycle=5) and also Telecide(reverse=false,swap=false,firstlast=false,post=true,threshold=15,dthreshold=9,blend=true,chroma=false,y0=0,y1=0) and Decimate(cycle=5,mode=0,threshold=0). If anyone had some ideas or different methods of doing this I'd really appreciate it if you shared.
Thanks, Mike btw I'm using decomb405legacy and mpeg2dec2. |

Is it a movie?
1080i may also be video and sometimes even 30p turned into 60i. I think Decomb without decimate would handle the 30p. You might also try TomsMoComp(1,5,1) or (0,5,1) if it was video. The HDTV flags often aren't used or reliable but you can usually tell by bringing it up on vdub preview without any of the above and stepping through it one frame at a time. One problem with HDTV caps is the on-the-fly encoding which will have cadence changes at edits caused by commercials, cuts, etc. And of course the commercials aren't necessarily from the same type of source as the show. - Tom |

Well "Without A Trace" is much more watchable after being ivtced than the previous two. According to dvd2avi it's 99% FILM and I just used telecide(guide=1) decimate(cycle=5). Sorta a pain it doesn't work for any other shows so far :/ This show only had 1 noticeable jerk every 10 minutes and pretty much all of the panning was smooth. Wheras all the other 1080i shows I've tried to ivtc had about 3 or so jerks a minute and very choppy panning. The original .ts is not jerky at all, I have checked that. I've sorta hit a dead end here.
