RESOLVED: TV capping - AVISynth scripting debacle

[jimmalenko]

Please bear with me as I'll be as forthright as possible in my opening post. I'll set the scene:

I am capping TV. I have aerial into VCR via coax, VCR into ADVC-100 via composite, ADVC-100 into computer via firewire. Capture using ScenalyzerLive into DV using Canopus compatible DV codec @ 720 x 576.

EDITING METHOD 1:
Edit using VirtualDubMod via the following AVISynth script:

LoadPlugin("Convolution3d.dll")
avisource("D:\scene0001.avi")

SeparateFields()
odd=SelectOdd.Convolution3D (0, 6, 10, 6, 8, 2.8, 0) 
evn=SelectEven.Convolution3D (0, 6, 10, 6, 8, 2.8, 0)
Interleave(evn,odd)
Weave()
DoubleWeave.SelectOdd()
ConvertToRGB(interlaced=true)

I then add the Trim points in where the blank line is. All going well up to this point. I open the script in TMPGEnc Plus, and encode using the following settings:













Encode for 80 minute cap takes about 3-4 hours. Resultant MPEG-2 is then authored using TMPGEnc DVD Author and burnt using Nero.

Playback on PC is brilliant. Playback on TV sees any moving object with about 4 "outlines" around it. I wouldn't say that playback is jerky, more like ghosty on moving objects. The strange thing is that I have attacked from a different angle with impeccable results:

EDITING METHOD 2:
Edit using VirtualDubMod via the following AVISynth script:

avisource("D:\scene0001.avi")

ConvertToRGB(interlaced=true)

I then add the Trim points in where the blank line is. Encode using TMPGEnc Plus with exactly the same settings, but this time use its internal Noise Reduction filter with a setting of 40-2-40.

Encode for same 80 minute cap takes about 24 hours. Resultant MPEG-2 is then authored using TMPGEnc DVD Author and burnt using Nero.

Playback on PC and TV is brilliant. No signs of ghosting at all.

Can anyone spot anything that might cause this ?

Naturally I'd prefer 4 hours to 24, but if it is going to take me this long to get the results I want then so be it - I'm prepared to do it the long way. Hopefully someone can assist.

Remove the DoubleWeave.SelectOdd() line from your avisynth script. DoubleWeave.SelectOdd() changes the field order, in your case from BFF to TFF. You can find out for yourself by using the Project Wizard in TMPGEnc.

I tried that using the wizard. Now I feel stupid

Do I need DoubleWeave.SelectEven to "force" it to BFF or will it just remain BFF unless changed?

[erratic]

Just remove DoubleWeave.SelectOdd() and your video will remain BFF.
There's no need for DoubleWeave.Selecteven().

Thanks for your swift assistance.

That'll make things a HELLUVA lot quicker.

Just wanted to add the final chapter to the story - it is now resolved. Removing DoubleWeave.SelectOdd() was all I needed to do.

Once again, thanks for the help, erratic.
