Hi there!
I recorded two videos today and now I'd like to know, if and how it's possible to open two videos at the same time, so that one video is played at the same time, only smaller and in one corner of the other one.
Here's an example of what I have in mind here:

Of course, they need to be merged together later.
Thanks in advance! |

Using an Avisynth script.
| CODE | main=avisource("C:\Users\Superuser\Desktop\clip.avi").ConvertToYUY2()
pip=avisource("C:\Users\Superuser\Desktop\clip_German3.avi", audio=false).ConvertToYUY2().bicubicresize(120,80)
Layer(main,pip,"add",255,1,1) |

prepare both videos
need same framrate, same width x heigh, same codec (Lagarith or anything that is fast and lossless)
same number of frames
second video save with filter: interpolate (x2 frame rate, nearest)
with framerate as for video 1 (video/frame rate/change frame rate to (fps):___)
(that doubles number of frames, making video 2x longer to play)
open first video. append first video again. then append second video.
(Example placing smaller, resized picture 320x180 over 640x360 in top-left corner)
filters: (right-click on filter to add inputs and name filters)
t = convert format (YV12)
f = fill (color: #000000) (x2 offset=320, y2 offset=180)
interpolate (x0.50,nearest) -- input for filter: t
resize ( 320x180 with leterbox (640*2-320) x (360*2-180) )
x = null transform (x1 offset = 320, y1 offset=180)
blend layers (screen 100%) -- inputs f & x
picture:
also theres is filter called Video Overlay http://www.trevlac.us/FilterDocs/ |

I would probably do it malky's way, but meowmeow's way interests me.
>t = convert format (YV12)
How is this done? I have not seen named filters before. I am on version 1.10.4.
EDIT never mind: add filter; right-click; name.
EDIT trouble:
"Cannot start filters: An instance of filter "blend layers" cannot process its input of 640x480 (YUV-420ib-709-Fr)
(wha?)

Yeah...ingenious use of filters, but Avisynth is easier & more versatile. No need to dub video or match codecs.
Here's a PIP function with simple positioning options (like Subtitle)| CODE | A=AviSource("A.avi")
B=Colorbars ## for example
## PIP, top right corner
UUPip(A, B, align=9, zoom=0.33)
###############################
### picture-in-picture effect
#
#@param A - main clip
#@param B - clip to appear over main; resized (see zoom)
#@param align - insert position, using "numeric keypad" notation)
# *---------*
# | 7 8 9 |
# | |
# | 1 2 3 |
# *---------*
#@param zoom - [default=0.5; max = 1.0; min = 0.1]
#
#@version 1.1 01-Aug-2011 raffriff
#
function UUpip(clip A, clip B, int "align", float "zoom")
{
zoom = Min(Max(0.1, Float(Default(zoom, 0.5))), 1.0)
inWid = A.Width
inHgt = A.Height
pipWid = B.Width
pipHgt = B.Height
B = BilinearResize(B, Round(zoom * Float(pipWid)), Round(zoom * Float(pipHgt)))
### add borders to all sides
bdr = 6
B = AddBorders(B, bdr, bdr, bdr, bdr)
pipWid = B.Width
pipHgt = B.Height
pos = Default(align, 7)
pos = ((pos==8)||(pos==9)||(pos==3)||(pos==2)||(pos==1)) ? pos : 7
### create PIP
iLeft = Round((pos==9) ? (inWid - pipWid + bdr)
\ : (pos==8) ? (0.5 * inWid - 0.5 * pipWid)
\ : (pos==7) ? (-bdr)
\ : (pos==3) ? (inWid - pipWid + bdr)
\ : (pos==2) ? (0.5 * inWid - 0.5 * pipWid)
\ : (pos==1) ? (-bdr)
\ : 0) # not reached
iTop = Round((pos==9) ? (-bdr)
\ : (pos==8) ? (-bdr)
\ : (pos==7) ? (-bdr)
\ : (pos==3) ? (inHgt - pipHgt + bdr)
\ : (pos==2) ? (inHgt - pipHgt + bdr)
\ : (pos==1) ? (inHgt - pipHgt + bdr)
\ : 0) # not reached
return Overlay(A, B, iLeft, iTop)
}

480<>360
If try to fix cropping in null transform VD crashes.
meowmeow's trip allows also to blend "fill" & "blend layers" filters to make additional effects using curve editor.
Can make second frame smoothly appear and disappear.
Forgot to tell, the paired video starts at N frame and ends and N*2 frame, where N = number of frames in original.
Yep, its hard to use. Waiting for special filter for the tasks... |

Sorry for the big delay, but I couldn't find any time to try out the script. Now, I tried malky's way, but I'm getting the following error message:

Malky assumed some basic knowledge of Avisynth
* install Avisynth
* in Malky's code, substitute your video paths for the ones in the script
* save code as: plain text, named <something>.avs ("<something>" can be any file name)
* Virtualdub File menu, open, <something>.avs
PS of course you won't get another error, but if you do:
View menu, Log, right-click, Copy
(instead of a screen shot) |

this I found
| CODE |
#la picture-in-picture AviSynth script with option to blend;
#may use VirtualDub FrameServe to FX; finally fill colour and edit curve for pop-ups
#reception
MainClip="video.avi"
FrameClip="pop_up.avi"
MoveFrameRight=0
MoveFrameDown=0
Blend=false
#file program
A=ConvertToRGB32(AviSource(MainClip,audio=true))
B=ConvertToRGB32(AviSource(FrameClip,audio=false))
#blend options
BlendMode="blend"
# (blend, add, substract, multiply, chroma, luma, lighten,
# darken, softlight, hardlight, difference, exclusion)
MaskColor=$000000
MaskTolerance=0
BlendOpacity=1.0
#overlay program
Blend ? Overlay(A, B, mask=ShowAlpha(ColorKeyMask(B,MaskColor,MaskTolerance)), \
MoveFrameRight, MoveFrameDown, mode=Blendmode, opacity=BlendOpacity) : Overlay(A, B, \
MoveFrameRight, MoveFrameDown, opacity=BlendOpacity)

honestly for simplicity i would just use the video overlay as one user above mentioned
