How to edit 4 videos into 1

[Craig Tucker]

I have 4 video clips that I want to show at the same time so they each take up a quater of the screen, can anyone tell me how to do this.

For example you can use Avisynth. Here is a sample script:

clip1=AVISource("e:\dir\filename1.avi")
  \  .BicubicResize(160,128,0,0.5).AddBorders(8,8,8,8) 
clip2=AVISource("e:\dir\filename2.avi")
  \  .BicubicResize(160,128,0,0.5).AddBorders(8,8,8,8) 
clip3=AVISource("e:\dir\filename3.avi")
  \  .BicubicResize(160,128,0,0.5).AddBorders(8,8,8,8) 
clip4=AVISource("e:\dir\filename4.avi")
  \  .BicubicResize(160,128,0,0.5).AddBorders(8,8,8,8) 
v1=StackVertical(clip1,clip2) 
v2=StackVertical(clip3,clip4) 
StackHorizontal(v1,v2)

Hey Truman,

that was cool.
Any more fancy avisynth examples up your sleeve?

Trueman,

I have put the dll file in the windows/system folder and ran the install file. But media player wont open the *.avs files I create. I am using notepad as my text editor. Any suggestions.

I notice that notepad still gives a txt extension eg TEMP.AVS.TXT, could this be the problem

Craig

[Craig Tucker]

That was the problem I enclosed the filename in quotes - "temp.avs" and it works.

Thanks Truman.

Although it appears to be working now if I use your script I get the error

Unexpected character "\"

This is my script

clip1=AVISource("c:\welbeck\capture01.avi")
\ .BicubicResize(160,128,0,0.5).AddBorders(8,8,8,8)
clip2=AVISource("c:\welbeck\capture02.avi")
\ .BicubicResize(160,128,0,0.5).AddBorders(8,8,8,8)
clip3=AVISource("c:\welbeck\capture03.avi")
\ .BicubicResize(160,128,0,0.5).AddBorders(8,8,8,8)
clip4=AVISource("c:\welbeck\capture04.avi")
\ .BicubicResize(160,128,0,0.5).AddBorders(8,8,8,8)
v1=StackVertical(clip1,clip2)
v2=StackVertical(clip3,clip4)
StackHorizontal(v1,v2)

Yes, it is quite difficult to post a script with long lines here, that's why I used the backslash. Actually you could copy the sample script and edit the filenames.
I try it once again.

clip1=AVISource("e:\dir\filename1.avi").BicubicRes ize(160,128,0,0.5).AddBorders(8,8,8,8)
clip2=AVISource("e:\dir\filename2.avi").BicubicRes ize(160,128,0,0.5).AddBorders(8,8,8,8)
clip3=AVISource("e:\dir\filename3.avi").BicubicRes ize(160,128,0,0.5).AddBorders(8,8,8,8)
clip4=AVISource("e:\dir\filename4.avi").BicubicRes ize(160,128,0,0.5).AddBorders(8,8,8,8)
v1=StackVertical(clip1,clip2)
v2=StackVertical(clip3,clip4)
StackHorizontal(v1,v2)

This is the same as the script above and the same as
clip1=AVISource("e:\dir\filename1.avi")
BicubicResize(clip1,160,128,0,0.5)
AddBorders(clip1,8,8,8,8)
clip2=AVISource("e:\dir\filename2.avi")
BicubicResize(clip2,160,128,0,0.5)
AddBorders(clip2,8,8,8,8)
clip3 etc.etc
v1=StackVertical(clip1,clip2)
v2=StackVertical(clip3,clip4)
StackHorizontal(v1,v2)

as long as there is no audio source in the script. If an audio source and AudioDub comes into the game I recommend to use one line for each clip (track). I noticed, that Avisynth ignores some filters if the order is wrong.

Avisynth is a video editor, so I could post hundreds of scripts. You should tell me, what you need. Or even better, read (and try to understand) the scripting language. Using Avisynth is much easier than most people believe. And once you got it, you will see, it is a great piece of software.

[Craig Tucker]

It worked, thanks a lot Truman, I'll get some brownie points for this one.

Cheers

it is a great piece of software.

It sure is. I have been using it semi-seriously for 12 months
but my problem with the manual is (and this is the same with
any scripting/programing language) is that I get lost too easily
just reading it. I'm one of those ppl that need to reverse engineer
someone else's applied efforts in order to kick my brain cells
into some sort of life.

So if you have any scripts you consider to be unusual or
of particular use, I'd be interested and others would be
as well, I should think.
