I have here another topic with another question. Every TAS for the Nintendo DS I have seen lately has had the following layout: http://www.youtube.com/watch?v=vrTvCqPtxao How is this layout achieved? I think I read sometime ago that it's a well - kept secret. If that's the case, then could someone explain why?

#Video

#splitting DS
i      = Height / 2
bottom = Crop(0, i, -0, -0)
top = Crop(0, 0, -0, -i)
right = last
left = bottom.Pointresize(bottom.Width() * 2, bottom.Height() * 2)
StackHorizontal(left, right)
 2022 Hijack: Switch the word "top" with "bot" in the last line of the script if you want the bottom screen instead. 
AviSource("video.avi")
cr = last.Height / 2
top = last.Crop(0, 0, -0, -cr)
bot = last.Crop(0, cr, -0, -0)
StackHorizontal(top.PointResize(512,384), last)
2022 hijack but you want to make sure it's right: 
source = AviSource("video.avi")
cr = source.Height / 2
top = source.Crop(0, 0, -0, -cr)
bot = source.Crop(0, cr, -0, -0)
StackHorizontal(top.PointResize(512,384), source)

Assuming that I am using VirtualDub, where would I put this?

Sorry, that code is avisynth (.avs) I assumed you had that installed it and made the file then dragged that into virtualdub (also updated code because I forgot one part) to view it (because it works that way too).

Where did you read that? The script producing this kind of layout is public (be it not too well documented).
All syllogisms have three parts, therefore this is not a syllogism.

VirtualDub does not allow stacking videos side by side.
Warning: When making decisions, I try to collect as much data as possible before actually deciding. I try to abstract away and see the principles behind real world events and people's opinions. I try to generalize them and turn into something clear and reusable. I hate depending on unpredictable and having to make lottery guesses. Any problem can be solved by systems thinking and acting.

Well, a long time ago I saw a LP video with that layout, someone commented asking how to achieve it, and the uploader responded by saying that, as stated above, it was a well - kept secret. I don't remember the particular Let's Player or video.

Is there any script to put in the ffmpeg custom command? It's more easy and straight forward in use, hence I would like to know if there is any script for it.
My TASing channel ; My MUSIC channel ; My SoundCloud ; My HomePage ; Music Composer ; Mr.TASer#5922 VCop 2 TAS completed, but in a completely different way ; And SMB - GAGOTO (WL) TAS COMPLETED TILL W-4 ; Some more...

Answer comes from here. Backhalf of the script comes from this topic here. Top screen priority: 
-filter_complex "[0:v]crop=iw:ih/2:0:0,scale=iw*2:ih*2:sws_flags=neighbor[left]; [left][0:v]hstack" -crf 18 -pix_fmt yuv420p -b:a 384k -f mp4
Bottom screen priority: 
-filter_complex "[0:v]crop=iw:ih/2:0:oh,scale=iw*2:ih*2:sws_flags=neighbor[left]; [left][0:v]hstack" -crf 18 -pix_fmt yuv420p -b:a 384k -f mp4
To change the scaling go to the bit after "hstack" and add (reasonings can be seen in my post): 1080p: 
,scale=iw*4:ih*4:sws_flags=neighbor,scale=1920:-1:flags=lanczos
720p: 
,scale=iw*2:ih*2:sws_flags=neighbor,scale=1280:-1:flags=lanczos
