Source: 720 x 576 MPEG2 PAL capture
use D2V avi as the feeder for MA script.

Output: 352 x 288 KVCD using TMPGenc

The Grip filters below caused a flashing edge on the right-side of the MPEG-1 output

>GripCrop(width=352, height=288,source_anamorphic=false))
>GripSize(resizer="LanczosResize")
>GripBorders()

However, with LanczosResize filter, the problem dissapeared.

>LanczosResize(352, 28


The problem can be re-produced.

Hi,

And whatif you use after GripCrop, a LanczosResize line, without GripSize? I mean, a line like this:
>GripCrop(width=352, height=288,source_anamorphic=false)
>LanczosResize(GripFit_resize_width, GripFit_resize_height)
>GripBorders()
?

Hi, Fabrice,

I tried that. The flashing edge is still there.

Hi, Fabrice,

The source is 720 x 576 MPEG2 PAL capture.

I am sure that the problem was with GripSize(). Since it was gone whith LanczosResize(). I guess there was a leaking when GripSize() does the work.

I have a screen pic but do not know how to put it here.
