Deinterlace vs ivtc ?
For the first time I got a NTSC interlaced movie, and I don't know how to encode it. All the movies I have done so far were PROGRESSIVE FILMS. :?
Is there a way to know if the film is telecined or it's just interlaced? And most important what should I do in both situation? There is tons of de-interlace / ivtc methods... Should I use AVS, TMPG, VDUB.... :?: :roll: :?: I tried this AVS script, but I did not get a smooth play. LoadPlugin("D:\DVD_Rip\mpeg2dec\mpeg2dec.dll") LoadPlugin("D:\DVD_Rip\decomb\decomb.dll") mpeg2source("C:\Temp\my_movie\movie.d2v") SwapFields() <-- with and without Telecide() Decimate() BilinearResize(352,480,0,0,720,480) What am I doing wrong? Or should try anything different? Help me please... |
First of all, you should open the VOB's with DVD2AVI, and press "F5". Let it run for about a minute, and look at the statistics window. What percent does it show FILM? Or does it only show NTSC?

It shows 29.970fps - NTSC - Interlaced

Well, the movie played smoothly!! :lol:
But... is there a way to make it 23.970 fps? And I just read in the AVS reference guide, that BOB uses a "dirty work". Is it the best shot? |
hey Mauddib,
I use FieldDeinterlace() all the time, but I've heard some people say they like Bob better (who's Bob? :lol: ) this is for IVTC with avisynth ntsc: Telecide() Decimate(cycle=5) Kwag, Do you load the VOBs into DVD2AVI and F5 then close and load into Mediator? I really wish Mediator had a statistics window!! thx, ren |

No, I just load the VOB's with Mediator, and it automatically selects or de-selects "Inverse Telecine", depending on the source. About bob :lol: , I've heard that bob() is not the same as Bob() 8O so check the docs on those functions. @muaddib, You can't Inverse Telecine what has not been telecined. So that movie must be encoded at 29.97fps. -kwag |

Now that we are at this subject, I just saw the release of decomb3.9 at doom9. |

I am confused now. I have "Unbreakable" DVD in this format
29.97--Film--Interlaced (I have double checked it, it shows this for sure!) What should I do with it? Please also give me the exact script for FitCD as well, thanks! If it is to be IVTC by using the script, do I leave it untouched at 29.97 in DVD2AVI?? |

If I'm doing a SKVCD (from a NTSC interlaced source), is it better to leave the movie interlaced or should I deinterlace?
What will give me more quality? |

SVCD ( and SKVCD ) support interlaced video. But you'll also have to encode at 29.97fps -kwag |

Looking at the DVD2AVI preview: FILM or >95% FILM ---> use force film and encode at 23.976 NTSC 29.970 ---> deinterlace for vcd, not deinterlace for svcd and encode at 29.970 FILM <95% ---> it is telecined. So you have to IVTC and encode at 23.976 Is that right? If it is, then I'm sure that my source is not telecined. :lol: |
Kwag,
Back to the issue "29.97--Film--Interlaced". You've tought me how to deal with the frame rate by using "forced film" in DVD2AVI, but how do I deal with "interlaced". Should I use "Bob" in FitCD or something else? Is it possible to convert it to "progressive" because I don't like the result of de-interlacing (I love KVCD-Plus 704x480 better than SKVCD). |

Hi kwag!
Some time ago I had a sound skip problem. With a 23.976fps source encoded as 29.970fps, the sound skip problem was solved, but the movie didn't play smoothly... so I discarded this option. I just figured out that with a source that is already at 29.970fps (like this NTSC interlaced) and I encoding at 29.970fps (as it should be), my DVD plays ALL KVCDs templates SMOOTHLY!!! :lol: :lol: :lol: BEAUTIFUL:lol: :lol: Well, for encoding this movie with KVCD-Plus_704x480 I have to deinterlace. So I tried with bob that you said, and with FieldDeinterlace that rendalunit said. I couldn't see any difference in quality, but somehow I feel more comfortable with bob (who is Bob? :lol:). The file size with bob is just a little bigger (~250k for 1 min sample). I also noticed a strange thing... When I load the BOB_AVS, TEMPGEnc (at video source type) says it's Non-Interlaced (as expected), but when I load the FieldDeinterlace_AVS, TMPGEnc says it's Interlaced! 8O Is that right, or I did something wrong? |

Kwag,
Please forgive me for bothering you again, I understand you message perfectly. The question is that DVD2AVI shows framerate=29.97, it also shows "Film" in the box right under the framerate, so what is it then (29.97 or film)? |

So your source is FILM. Select "Force FILM" for your project. :D -kwag |
