How to keep AVS file interlaced after rendering?

[Master Tape]

I want to make some copies of our home videos and put them on USB sticks for viewing, but everytime i've tried to render them in FFmpeg, vdub, they always seem to come out as Progressive.

AVISource("I:\June 1996.avi")
AssumeTFF()
AssumeFPS(25)
ConverttoYV12()
ex_vibrance(1.3)
SmoothTweak(brightness=-10,contrast=1) 
UnsharpMask(strength=36, radius=3, threshold=8)

Maybe you encoded them as progressive. Set your encoder to encode interlaced

ConvertToYV12 should be ConvertToYV12(interlaced=true)

You can't use UnsharpMask on interlaced content while fields are interleaved - You will co-mingle the interleaved fields . Either 1) deinterlace, sharpen, reinterlace ; or 2) separate fields , sharpen, then weave

or 2) separate fields , sharpen, then weave

Beware that that will create thicker and more severe halos (ringing artifacts) on sharp horizontal edges.

I see. What is the least destructive deinterlacer, and how do you reinterlace?

AssumeTFF().SeparateFields().SelectEvery(4,0,3).We ave()

For example, AVStoDVD generates this code when the source is tff:

Video = Video.LeakKernelBob(1,7,false,false)
<other filters>
Video = Video.SeparateFields().SelectEvery(4,1,2).Weave()

and this when it's bff:

Video = Video.LeakKernelBob(0,7,false,false)
<other filters>
Video = Video.SeparateFields().SelectEvery(4,0,3).Weave()

[Master Tape]

It's still rendering as Progressive.

-vf setfield=tff -aspect 4/3

[davexnet]

It's still rendering as Progressive.

In Vdub2 ? You have to put the field order in the vdub x264 settings box, either --bff or --tff

[lollo]

I see. What is the least destructive deinterlacer, and how do you reinterlace?

AssumeTFF().QTGMC(lossless=1)

<filtering>

AssumeTFF().SeparateFields().SelectEvery(4,0,3).We ave()

How should the last line be if the source is BFF?
AssumeBFF().QTGMC(lossless=1)

and this when it's bff:

Video = Video.LeakKernelBob(0,7,false,false)
<other filters>
Video = Video.SeparateFields().SelectEvery(4,0,3).Weave()

Sorry, I do not understand the question. If the source is BFF, replace TFF with BFF in the script. The repetition in my example is redundant.

I do not know AVStoDVD, but working with separated fields for spatial/temporal filtering is not appropriate.

Yes, it's my own confusion : SelectEvery(4,0,3) vs. SelectEvery(4,1,2)

In FFmpeg i meant. Thanks for that though, it did the trick. I suppose there's not much difference in quality between x264 and FFmpeg? Also how do you set the aspect ratio flags in x264? or is it better to just let the tv do that?

[jagabo]

If you have to deinterlace to filter, why not keep the final video progressive?

[Master Tape]

Good question. Unless there's a way you can sharpen the video without having to deinterlace?

Don't know how well it works with sharpening, but you may try:

separatefields()
e=selecteven().<filter>
o=selectodd().<filter>
interleave(e,o)
weave()

interleave(e,o)

The video ends up with half the height resolution (704x288)

I edited my post. You have to add weave(). Sorry.

[Master Tape]

Script error: Invalid arguments to function 'weave'.

[Sharc]

Don't know your AVS2DVD script. Maybe you have to use 'video=video.blabla' in the script.

[Master Tape]

Sorry, this is in AVSPMod. I'm not using AVS2DVD for this particular task.

AVISource("I:\Video.avi")
ConverttoYV12(interlaced=true)
AssumeTFF()
separatefields()
e=selecteven().UnsharpMask(strength=36, radius=3, threshold=8) 
o=selectodd().UnsharpMask(strength=36, radius=3, threshold=8) 
weave(e,o)
ex_vibrance(1.3)
SmoothTweak(brightness=-10,contrast=1)

[davexnet]

Looks like there's something missing, should be weave(clip)
Jagabo has interleave(e,o) just prior, in which case weave()
should work

Thanks, looks like i missed interleave then got confused by the post edit and changed it to weave. Looks alot better!
