I’ve had the pleasure of using a trial of SNELL Alchemist On Demand to recently convert some SD Interlaced PAL material to NTSC SD Interlaced. The conversion looked great – almost zero ghosting, something that Sony Vegas is incapable of doing.
Being that Snell products are incredibly expensive, it begs the question to if there is a close Windows-based conversion software or Avisynth script?
When I convert 50i to 60i in Sony Vegas, I get lots of ghosting and strange artifacts (i.e. horizontal line shaking). When using Snell’s product, it looks like there is some form of motion compensation/interpolation used to deinterlaced it and create new frames.
I also do not want to slowdown (impossible as it’s interlaced) nor discard any fields.
Surely the same methods are possible on (much) cheaper software or free tools like Avisynth? Anyone know a way?
Here’s a link to a 50i file if anyone wants to give it a go.

You might not like the result; I don’t much. And I don’t envy you your source material.
