Line flickering problem on doorframes etc on Progressive video
Hi all
Firstly, I apologise in advance for being a relative noob at all this stuff I've got a DVD in VOB format where at the beginning of the scene (and in other parts) there's horizon & vertical line flickering which is *really* offputting, and I want to try and get rid of it the best I can when encoding it. Here's a screenshot to show you what I mean, as a screenshot is going to show much better than me trying to explain it properly! xD http://gyazo.com/1ed09b9ef10ddbb3e63...png?1352036954 As you can see, the jagged lines on the doorframe close to the 2 people, and the lines of the tiles on the floor, and most noticably at the bottom of the door in the left background, there is also flickering on the door handles in the background on the 2 doors to the left of the 2 people. This screenshot is from the untouched vob file, source is PAL and 16:9 Progressive, there's no visual interlace at all in any of the entire video, just these annoying jagged lines! Just some other info for what I use when encoding MeGUI (latest dev version) Avisynth 2.5 QTGMC deinterlacer SDB Profiles for MeGUI DGIndexNV Also, to kill 2 birds with 1 stone (in other words, I might as well ask another question at the same time) I have these avisynth scripts set up for use in avisynth script creator in MeGUI, do these look okay for use with each type of video, or am I missing something that should be there? #Interlaced 30fps BFF script SetMemoryMax(1400) setmtmode(5, 4) <input> setmtmode(2) AssumeBFF() SelectEven() <crop> QTGMC( Preset="Slower", edithreads=1 ) #Interlaced 30fps TFF script SetMemoryMax(1400) setmtmode(5, 4) <input> setmtmode(2) AssumeTFF() SelectEven() <crop> QTGMC( Preset="Slower", edithreads=1 ) #Progressive script SetMemoryMax(1400) setmtmode(5, 4) <input> setmtmode(2) <crop> QTGMC( Preset="Slower", InputType=1 ) #Telecined script <input> TFM() TDecimate() <crop> Thanks in advance guys, I'm a novice with avisynth etc, so you'll have to bear with me when explaining stuff Kind Regards |

a) yeah, the source is Progressive, but its been badly deinterlaced... can anything be done about it?
b) Alright thanks, so SelectEven() should be at the bottom of the script? c) <crop> is in there as part of the 'default' script, if it stays as <crop> it doesnt crop at all, the <crop> bit changes if I use MeGUI and crop something, its like a placeholder for it. d) I did some reading up on the QTGMC script and apparently its quite good at removing artifacts from Progressive video, so I thought I'd give it a try. I use it for general deinterlacing normally. |

Btw, for a Progressive video shall I put SelectEven() at the bottom of the script, or shall I only use that for Interlaced content?
I've now changed my avs default script for Progressive to:- <input> <crop> <input> changes to the location of the .dgi file when I open it in the avisynth script creator in meGUI as does the <crop> line if I have to crop something. Is that alright? Thanks for your help/suggestions btw. Last edited by simcut; 11th November 2012 at 15:36. |

It was in response to someone saying that it was badly deinterlaced (and I agree, the company who put it on DVD have really made a mockery of doing it!) I bought the DVD and have a physical copy of it, I am trying to encode from Source DVD to mp4 x264 Will be quite happy to prove the legitimacy of it. Bit frustrating spending money on a DVD and then find out it looks like shit when u play it :\ I'm just in the process of making an .iso from the source dvd so that I can do work on it without having to keep the dvd in the drive, will put up the demuxed video in a bit Last edited by simcut; 27th January 2013 at 21:38. |

Right, here's the demuxed video at long last.
http://www51.zippyshare.com/v/16656039/file.html and here's a screengrab of what DGIndex shows for it - http://i.imgur.com/Id08CiE.jpg it shows it as Interlaced TFF 25fps (so must be PAL) If you want me to upload the .dgi as well let me know Thanks in advance, hope you can help with this, you'll really notice the problem on the doorframes etc..
