I have a video that suffers from a "venetian blind" style problem, as at the bottom left corner of the following still:
http://homepage.ntlworld.com/andy.durrant70/videos/riverside still.jpg
The video (a short extract is hosted here: http://homepage.ntlworld.com/andy.durrant70/videos/Riverside extract.mpg) is a progressive NTSC conversion of an interlaced PAL videotape, which I've lost. Each NTSC frame appears to be a blend of two PAL frames - one set of stripes from frame A and the other set from frame B. Conventional Inverse Telecine filters don't help me as the blend is not based on alternate lines - the stripes you see are three lines high (80 stripes in total).
Are there any Avisynth filters/plugins that can divide the stripes and reconstruct the original frames? Failing that, does anyone know of a virtualdub or avidemux solution?
