Need help deinterlace 1080i 29,970..

[S3Ri0US]

Hi there.. i whant to deinterlace a HDTV Movie 1920x1080 interlaced 29,970 Fps with AviSynth... I have tryed to use the ffdshow deinterlace stuff but the length of my final Movie will 4 Minutes shorter then my Audiofile. so. is there any way to deinterlace the Input that the MovieLegth is the same like the input ? or can i deinerlace the Movie to 23,976 Fps ? Thanks a lot for your help.

Hello S3RoOUS,

there are a lot of deinterlacers out there. Go to this wiki page (http://avisynth.org/mediawiki/External_filters#Deinterlacing) and have a further read. And read everything you find about 3:2 pulldown to understand how progressive film material is stored to ntsc-video.

i dont get it work.... is there a Way to use DGAVCIndex and AviSynth ? avcsource ?

Please post a sample of your unprocessed source stream. To give you the correct advice we have to know for sure the nature of the video.

And saying "i don't get it to work" is a wholly unsatisfactory report. You have to tell us exactly what you did and what happened.

Here is a sample:

http://rapidshare.com/files/208537230/doom9.m2ts.html


I have tryed following:

-------------------

i load my m2ts file in DGAVCIndex and selected: Field operation -> Forced Film

then i saved the project.. after this i created my AVS file:

loadplugin("D:\DGAVCIndex\DGAVCDecode.dll")
loadplugin("D:\DGAVCIndex\Decomb.dll")
avcsource("D:\DGAVCproject.dga")
fielddeinterlace()

-------------------

My first test:

LoadPlugin("C:\AviSynth\Plugins\TIVTC\TIVTC.dll")
directshowsource("d:\st2_hdtv.m2ts",fps=29.970,audio=false)tfm().tdecimate()

but here i think i must set some options for tfm and tdecimate.. but i dont know witch...

Tanks for Help

Giving us just the studio intro is really useless. You have to give us a part of the movie! The intro section you gave is progressive and doesn't need deinterlacing or IVTCing.

Use DGSplit or equivalent to cut out a part of the movie itself, or make a longer clip from the start so that the movie is included.

DG Split does not work.. i cant play the splittet Files.. And the intro is interlaced.. i see it when i change the Size in Media Player CLassic from FullScreen to half or resizing the Player Window.. but.. here is another:

And the intro is interlaced Correct, sorry, I had my PureVideo deinterlacer turned on. :)

Standby for further reply after I look at the new stream...

It's hard 3:2 pulldown. Make a project with DGAVCIndex and then use this script:

loadplugin("dgavcdecode.dll")
AVCSource("doom9-2.dga")
telecide()
decimate()

Ok Thanks a lot i will test it.

Edit: when i play my AVS in MPC the Movie will run verry Lagy/Stottering is this only a problem when i Play it direcly ? Or will the Encoder habe the same Problem ?

[scharfis_brain]

don't ever use a mediaplayer to preview scripts!

use virtualdub to preview them, cause it allows you to step frame by frame.

ivtc most commomly analyses five frames at once (takes its time) and then spits out four frames at once (in virtually no time). this explains what you noticed as stutter in the media player.
a encoded file will run fine.

When i create the Project in DGAVCIndex what Field Optione i must use ?

[Guest]

Use Honor Pulldown.

Anyway, those options aren't implemented yet, so it doesn't matter.

Hmm I thought the Field Operations were only unimplemented in DGAVCIndexNV, but are functional in regular DGAVCIndex.

[Guest]

Oh, yes, that's right! I forgot I implemented it for DGAVCDec.
:stupid:
