View Full Version : Avisynth Filters Supporting Interlaced Content

Hi all,

Recently I did some research to find out which avisynth filters support Interlaced content - mainly because I like doing VirtualDub captures from VHS to ffdshow huff with Avisynth "Image Processing"

So far:
_2DCleanYUY2 - YUY2 ColorSpace + Interlaced
DeGrainMedian YV12 & YUY2 + Interlaced
TTempSmooth YV12 & YUY2 + Interlaced
VagueDenoiser YV12 & YUY2 & RGB + Interlaced

My concern comes about from some info from TTempSmooth Help File which states under the Parameters:

interlaced - (interlaced yv12 input)

Set this to true if you are using ttempsmooth on a YV12 interlaced clip... otherwise set it to false. This setting only effects YV12 input and has no effect if the input is YUY2 because interlaced YUY2 needs no special handling.

What exactly does this mean? Do it mean that as long as I capture in YUY2 I can use other filters that do not make an allowance for Interlaced content - or does it just apply to this
TTempSmooth filter only.

TIA

Don't forget you can always do...
bob(0.0,1.0)

#Put whatever progressive-only functions you need here

separatefields()
selectevery(4,0,3)
weave()
...to run interlaced content through progressive-only functions/filters.

IIRC this conversion interlaced > progressive > interlaced is lossless in some colour spaces, but not in others.

Depending on what the function does, you might want to use a better bobber.

Cheers,
David.
