This is challenging :/

or at least it's a challenge for me. i'm not very proficient in avisynth, though.

telecide and decimate get rid of the interlacing, but makes the frames that fly off of the screen look choppy.
sangnom seems to do a bit better with handling the frames the fly off of the screen slow, but not the ones that fly off of the screen fast.

:/

i suggest you view full screen to see the interlacing problems

I don't have decomb.dll anymore...but IIRC there's an x-axis threshold value and a y-axis threshold value, try changing these values until you get a good result (you'll have to look through the documentation to find the real parameter names)

changing these parameters changes the sensitivity of telecide's search which can mark more/less frames as combed depending on the value you give it.

avisource("SAMPLE.avi")
ConvertToYV12()
Telecide(order=1,post=2,blend=false,vthresh=30,back=1)
Decimate(cycle=5,mode=3,quality=3)

avisource("SAMPLE.avi")
ConvertToYV12()
Telecide(order=1,post=4,blend=false,vthresh=30,back=1)
Decimate(cycle=5,mode=3,quality=3)

avisource("SAMPLE.avi")
ConvertToYV12()
Telecide(order=1,post=2,blend=false,vthresh=30,back=1)
Decimate(cycle=5,mode=1,quality=3)

theres more, but not worth posting. pretty much the same thing. just changing post on telecide and the mode and decimate

try lowering vthresh and try including dthresh (default is 7, range 0-255)
never used dthresh myself, so I don't know if you should increase or decrease it

then try TFM and Tdecimate
you can get it from here (look for TVITC)

managed to take care of some rahXephon test footage that was giving me a hard time. try the following
Code: Select all
TFM(order=-1,mode=5,PP=7,field=-1,slow=2)
tdecimate(mode=1)

* I mean replace telecide and decimate with TFM and Tdecimate respectively

Do I understand it right? You try to deinterlace a finished AMV, which got resized while it was interlaced? And you decimate it too?

That sample that you did post is doomed. It makes AviSynth crash if I use TFM, which I wanted to suggest either. No matter if I convert it to Lagarith instead using the XviD.

it made VDM crash, or it actually made avisynth crash?
the script ran for me, but it just made the footage choppy

It made AviSynth crash.

If the footage becomes choppy, don't decimate and work with 29.97 fps

exactly how this was setup:
any 720x480 source was cropped to 640x480
640x480 sources were left alone
widescreen stuff got boarders and lanczosresize to make them 640x480
all footage i edited with was interlaced. ya. not doing that again :roll:
