kayman

oops i forgot my avs

LoadPlugin("f:\decomb.dll")
LoadPlugin("f:\Convolution3D.dll")
LoadPlugin("f:\simpleresize.dll")
LoadPlugin("f:\TemporalSoften2.dll")
LoadPlugin("f:\greedyhma.dll")
AVISource("E:\jm.avi")
trim(664,163772)
Telecide(blend=false)
decimate
#GreedyHMA(1, 0, 0, 0, 1, 1, 0, 0)
#Convolution3d (0, 6, 6, 8, 8, 3, 0)
TemporalSoften2(3,3,3)


EDIT by dividee: image deleted (better one below)

Sorry I can't see what you mean. All I can see is jpeg blocks. Post a png, prolly even with a large "Look here" arrow.

I don't see any problem either.

If you're going to post uncompressed, please crop to just the area of interest. Otherwise the moderator may not validate the attachment.

heres a zoom in of it its hard to see on the image but in hte mpegs its very noticable

[kayman]

im using DV avis and its not present at all
for mpeg bitrates im using 0 - 9000 avg 4500

the avis are pristine and those lines are not there its only in the mpv afterwards

Hi there.

Although your script did not show any resizing going on, these look like the jaggies produced by some resizing algos.

Did you omit the resize in your avs? Did the zooming required add/augment this artifact?

Just wondering!

[kayman]

no no resize at all caped at 720x480 mpeg is 720x480

I've been looking at the picture a couple of times and I'm quite certain that the artifacts are created by Telecide(post=false). The areas have probably been detected as interlaced, and a new pixel value has been interpolated. this could explain why it looks resized, as interpolation and resizing is basically the same thing. Try changing the threshold values a bit. Look in Decombs readme, I'm sure you can get some hints there on what to change.

@hakko504

You meant blend=false of course.

Try setting post=false and seeing if the area in question comes out interlaced. If so, then hakko504's theory is most likely correct. You'll have to decide which is the worst evil for you, interpolation or blending.
