I am looking for a script that will convert side by side (parallel) to the older field sequential format. Nowadays everyone wants to do the opposite which is understood and likewise there is a ton of info on how to do this. However sbs to fS script is not. Can anyone help me out?
The source was an overseas 3D blu I picked up (the Germans did a decent 2d to 3D conversion,but more pixel shift and rotoscope job for the 1982 animated film the Last Unicorn) that I then converted to sbs with BD3D2MK3D. The irony is that I love 3D but do not own a 3D set. I do have some 3D blues and player but if I truly want to view these I convert to sbs or anaglyph (I know) and view it on the pc in a small window (for side by side) so it doesn’t kill me eyes entirely (I can free view parallel).
I still have the older analog field sequential
equipment and would not mind viewing this film on my crt tv in that format
The 3D mkv made is also 16x9 which I would like to keep if possible

I know I have copies of those scripts somewhere at home, so I'll look for them this weekend...
Off the top of my head, something along the lines of:
WhateverSource("filename.ext") left=Crop(0,0,width/2,height).Spline36Resize(width,height/2) right=Crop(width/2,0,width/2,height).Spline36Resize(width,height/2) Interleave(left,right) AssumeFieldBased() AssumeTFF() Weave()
But you can convert to anaglyph without interlacing. Scripts for that have been posted many times here. For example:

Thanks again but as mentioned in my first post the Stereoscopic movie player
can also do on the fly conversion quite well but I would rather be able to watch this edition on my dvd or bluray deck and for that I need to truly do an encoded conversion. And the script provided by Jagabo (and possibly also from Scott) will help me do what I need
All above is true however Avisynth is inherently single thread (without MT) - ffmpeg offer some multi-thread capabilities, side to this conversion can be performed with ffmpeg and in semi-automated way (ffmpeg provide decoding, filtering and encoding within single binary thus you can avoid some problems with Avisynth).
I like Avisynth, i use Avisynth but sometimes it is not most optimal solution IMHO.
