DVD interlacing showing (Avisynth/HCencoder error)

[kieranvyas]

I am trying to make a PAL DVD but the final result is showing interlacing scan lines when played on my DVD player. I have read other threads about people having the same problem when trying to encode a PAL dvd, but no solutions. This problem seems to exist when dealing with PAL specifically. Does anything in my script contradict with PAL in any way, maybe? (I have uploaded a short clip a couple of posts below.) Please help

Source: 50p 1920x1080

Avisynth script:

AviSource("final2.avi")
ConvertToYV12()
Spline36Resize(720,576)
Blur(0,0.5)
ColorMatrix(mode="Rec.709->Rec.601",clamp=0)
AssumeTFF().SeparateFields().SelectEvery(4, 0, 3).Weave()

HCencoder:

Bitrate - Avg 4000, Max 9000
Profile - Best
Aspect ration 16:9
Autogop - 15
Interlacing - auto detect, TFF
Chroma Downsampling - progressive
Matrix - manono3

Interlacing - interlaced, TFF

Interlacing - interlaced, TFF

Tried that, exactly the same results unfortunately

Upload a short sample of your M2V.

here is a clip! Thank you

That m2v is encoded progressive.

That m2v is encoded progressive.

Really! I'm using that avisynth script and those HCencoder settings, how can it be progressive? When I drop the clip into Premiere Pro it tells me it is 25.00i UFF? What am I doing wrong? Thank you!

Go back and reencode as interlaced TFF again.

Your sample is incorrectly flagged ("Frametype progressive" is true, which it should not) and also it was encoded using zig-zag scan type which is entirely incorrect for interlaced encoding.


In HCenc, Settings 1:

interlacing options (this determines the scan type and the "Frametype progressive" flag):

• Interlaced
• TFF


Chroma downsampling shouldn't have any effect since you are feeding YV12 rather than YUY2.

[kieranvyas]

Go back and reencode as interlaced TFF again.

Interlacing options - Interlaced - TFF. Same thing!

That one is properly encoded interlaced. It should play properly after authoring to DVD -- assuming you don't reencode it progressive.

Amazing, it works! Thank you so much
