tmpgenc is putting 2 lines of puprle at the bottom

[lancer]

I've tried god knows how many methods but this keeps happening.

If I take a source captured at 704 x 480.

I've frameserved from vdub to tmpgenc.
I've used an avs script to go direct to tmpgenc.
I've opened a file directly in tmpgenc.

every time the output has 2 lines of purple at the bottom of the encode.

I've tried using clip frame in tmpgenc to clip the bottom 4 lines and then masking back to 702 x 480 but it still does it.

using vdub 1.4.9 and 1.4.13 and tried tmpgenc 2.56 and 2.59

my script

loadplugin("d:\convolution3d.dll")
loadplugin("d:\decomb.dll")
segmentedAviSource("D:\raiders.avi")
telecide(guide=1, post=true)
decimate()
tweak(bright=-3,cont=1.02,sat=1.3)
convolution3d(0,32,128,16,64,10,0)
#Convolution3d (preset="movieLQ")
letterbox(48,48)
bicubicresize(720,480,0,0.5, 720, 336)

I've tried not letterboxing or cropping and I still get them. grrrr

Have you tried actually doing a BicubicResize(720,480) for instance?

Or try a LanczosResize()?

[lancer]

you mean losing 0, 0.5 from the line?

can give it a go I suppose but it was doing it before that when I used resize filters in virtual dub as well. it's not just specific to avisynth script. could it be something in the sizing and cropping that's throwing this up?

*cough*
