ivtc question again :P

[c0de_v0id]

hi, this is my first post here
i have an hkdvd anime which is interlaced mostly with this pattern 1,1,0,0,0(1's are interlaced). of course there are other out-of-pattern interlaced frames as well.(really ****** up :P)
just wondering if there's a way to ivtc it? i mean like delete one of the interlaced frame and then deinterlace the other one?(but then it wont give u 24fps)
or just keep the frame-rate and use deinterlace?
(I tried using IVTC and decomb filter, followed by telecide but telecide didn't do a good job of cleaning up the rest.)
any other combination of filters?
thanks

You didn't use Decomb correctly, because what you said makes no sense. What script did you use?

[c0de_v0id]

decimate(mode=2)
telecide()
i think decimate did it right, one of the interlaced frame disappeared. but telecide didn't blend the interlaced ones.

:edit:
if u've seen a hkdvd u'll know.. i think they recorded the episodes to vcr and put those into dvd

You have the commands backwards. For IVTC it should be:

Telecide([options])
Decimate([options])

If you just want to deinterlace (no change in frame rate):

FieldDeinterlace([options])


You should really read the help file that comes with the plugin, all options are very well documented.

Try using decimate(guide=1).

I've found that i get the best reults on anime doing that.

@meleth

A little faux pas in your post, no? (You meant Telecide().)

@c0de_v0id

Try this script for your anime:

Telecide(guide=1,gthresh=50)
Decimate()

Don't you read help files? :)

[meleth]

hehe yeah, my mistake :P

While we are on the topic of IVTC...

@Donald

I am hesitant to use reverse=true in telecide, although I think it makes the IVTC of my movie better. Its a HK Kung Fu film. I have determined that the field order is Bottom first. By this basis alone can I make judgement to use reverse=true? I know in the IT filter it needs such a parameter.

Thanks for the clarification,

Dali

P.S. I think I recall you saying a while back that Decomb doesn't need to know the field order...correct?

@Dali Lama

Look here for an explanation of the theory of operation of Telecide() and the significance of the reverse option:

http://forum.doom9.org/showthread.php?s=&threadid=31475

In short, yes, Telecide() does not need to know the field order, and the reverse option helps only in some pathological cases, such as where blended fields predominate in only the top or bottom field.

[c0de_v0id]

thanks you guys...
telecide(gthresh=50,guide=1) works but it didn't totally blended the interlaced lines. i can still see small lines there.
im testing the script with different options right now.. i'll post my results here later

First use the debug utility to determine if the frames with residual combing are being detected as combed. If they are not, reduce the threshold parameter to Telecide() until they are detected as combed. If they are detected as combed, reduce the dthreshold parameter to Telecide() until the artifacts go away.
