newbie problem with deinterlace

[awe007]

hi,

because i´m new to avisynth i´m still doing some test. i got several historical movies captured on tv (pal). i checked the movies in virtualdub and saw interlace lines. therefore i did a simple avs script with different deinterlace filters (tomsmocomp, Smoothdeinterlacer ) and ran it with vdub. unfortunaley nothing happened. i can still see all the interlace artefacts.
in a next step i added info() which told me "filed based video: no".

no i´m realy confused. i´m only looking for a way to get rid of the interlace lines because i want to encode the movie (with dvd2svcd, cce) to svcd.

i would appreciate any help ....sorry for the questition but i don´t know what went wrong...

thx

Post your AVS script and a screenshot of the before and after frame.

..ok....below the input and out frame.

..having again a look on it you can see some differences but not the effect i wished the filter to do. i thought a deinterlace filter completely removes the interlace artefact. perhaps someone can give me any information about the filters which can solve my problem.

thx

Deinterlacing works best on original 480 (NTSC) or 576 (PAL) height material.

Capture your video at one of these settings and then try the deinterlacing filters.

To completely remove any interlacing artefacts use VirtualDub's deinterlacer (Discard Field sub-option)

hi,

i didn´t capture it by myself....i just got the movie as it is (unfortunaley). are there any differences between deinterlacing in vdub or via avisynth..?? i thought both can use the same filters therefore i was looking the one that can solve this problem...

i just used the vdub filter with no success...there are still interlace artefacts...:-(....very strange...

The reason deinterlacing isn't working is that you don't have the original source.

Give up and have a beer :)

I deinterlaced a VHS movie on my computer for putting on a DVD, the results were great

I used TMPGEnc Plus, loaded the m2v (or Mpeg file) and choose Load: DVD (NTSC) --> its inside the Template folder, like c:\Program Files\TMPGEnc Plus\Template. press ok.... and now you are back to the main window
then, click setting, and go directly to the Advanced Tab, leave everything as it is, just check where it says deinterlace and double click its name. Once you are there, choose the method you want the program to use to deinterlace the video, theres a preview window on it, so you can see which of them will give you better results.
When you are satisfied, press OK and press OK to the Settings window also.
Go to Options -> Preview Option -> Do not Display (this will make it faster)

Choose a Stream type (since I always use .mpg videos, I always choose the program to separate the audio from the video, so I choose ES (Video + Audio), but you can choose anything you like for an output (just put the mouse over and youll se an explanation of each setting.

Press the Start Button and off you go. ;)

although most people pry dont deinterlace this way... I DO.. and it works for me..it decreses the chance of ghosting...

get the latest decomb.dll plugin (for avisynth 2.5).... a link to the avisynth plugins is somewhere on this board(easy to find... im just too lazy to find it for you right now)

and try experimenting with Telecide.. and deinterlace... or BOTH...

try different settings.. and use the DEBUG.. so you can SEE what is being analized.. (if you stay away from decimate then the frame rate should stay the same..)

however, like someone says, its hard to redo something that is already compressed.. BUT if the framerate is the SAME as the orginal...(yah i know its from TV.. but it still can be fixed a little more that he has right now) It may be repairable.. a little more that what you got right now...

ALSO.. i would NOT convert the colorspace to yuv2.. just to save headache if that messes up the deinterlacing process..(try to do as little as possible when tweeking a vid file.. then when you get somethign working .. move onto the other ****..) thats just comon sense when doing debuggin.

Did my own subjective worldline suddenly dive off into the far side ?

[fedge]

no siwalters, i didnt.. i totally agree with you.. but sometimes a file CAN be redone.. but this person will HAVE to put up with a loss in quality(even more so than putting up with the crappy combing effect.)...

he may want to try to play the file in a dvdplayer application and force a deinterlacing there.. somehow the file can be fixed.. or he just may have to do the hard partand retrace where the file came from and get the author to redo it...

[and im not stupid but even though rule#6 exists its broken here dialy.. just not outright.. im sure this is a case of dl material--]

[awe007]

fedge,

of course it is download material...it´s from edonkey....but there´s no rule violation because this is just a captured movie broadcasted on germany tv (sat.1 / spiegel tv reportage). it is a history documentation about world war 2.
