I wonder, if there exist a plugin, witch will allow over still image, or even a video another video(s) - smaller of course - to be placed over it. I wonder if something like that can be done, or if it even actually do exist. Becuase I check the plugins list and did not find anything that will do the trick to put a 2, 3 small videos at the same time over a still or another bigger video...
Anyone can help me out, or this is not possible?

For anything 'special' like this it'd be easier to use Avisynth and write a script
Here's a sample script
| CODE | a=Directshowsource("O:\mainvideo.wmv",pixel_type="RGB")
b=Directshowsource("O:\overlay.wmv",pixel_type="RGB").bicubicresize(320,240) #resize overlay video to 320x240
c=overlay(a,b,16,16) #overlay the second clip at x=16, y=16
return(c)

The function "overlay" is not perfect in AviSynth (some noisy). That is why I recommend to use ImageMagick for it.
1. Export first video to a sequence of pictures .bmp
2. Resize second video by AviSynth and export to a sequence of small pictures .bmp
3. Move the sequence of small pictures in the same folder where background pictures are located.
4. Use ImageMagick.
Text of .bat file:
| CODE | @echo off
echo Hello this is a batch file for overlay
::Background images must have the prefix bgr_ in the beginning their name, but overlay images must be top_ exactly
mkdir overlaid
setlocal EnableDelayedExpansion
for %%a in (top_*.bmp) do (
set file=%%~nxa
set file=!file:top_=!
echo. Processing file: “%%~nxaâ€
convert bgr_*!file!.bmp %%a -composite -alpha off overlaid\over_%%a
) |
5. Recreate .avi file from a sequence of overlaid pictures |

A quick search gives twelve overlay filters located here http://www.infognition.com/VirtualDubFilters/ |
