Really need some help with an odd video question

[jango62301]

So after doing a lot of looking I found this place to be the best to ask questions. I have an odd question. I am school teacher and we are in need of the ability to split a video into 4 triangular pieces like the video in the link below.https://www.youtube.com/playlist?list=PLxpk8QYH9aNuM0Tbs7C8_ogkLO48M_VhD.

Can someone please point me in the right direction for the correct forum or maybe an idea of how to do this? I am desperate.

Create four 90 degree rotated version of the video. Join them together in a 2x2 matrix. Rotate 45 degrees.

Wierd, the site won't let me upload any more images.

Thank you so much for the advice! I am a total newbie, is there a particular software that you would recommend to accomplish this? I have never actually tried editing a video before.

Pretty much every video editor has this type of compositing. All the commercial editors have it. I'm pretty sure the free AviUtl has it. I did it with a quick AviScript:

v1 = ImageSource("picture.jpg").ConvertToYV12()
v2 = v1.TurnRight()
v3 = v2.TurnRight()
v4 = v3.TurnRight()
StackVertical(StackHorizontal(v1,v2),  StackHorizontal(v4,v3))
Rotate(45)

You would use a video for v1 (and hence v2, v3, and v4) instead of a picture. Using whatever source filter is appropriate. Like AviSource(), ffVideoSource(), etc.

jagabo, First I turned the single image into a video and used it as an inout to your script but I kept getting an error on the script you posted but I rearranged it and since my photo wasn't square(error on height mismatch during stack) I used:

v1 = DirectShowSource("C:\Users\Bud\Desktop\image001.fl v").converttoyv12.lanczosresize(320,320).rotate (-45)
v2 = v1.TurnRight()
v3 = v2.TurnRight()
v4 = v3.TurnRight()
StackVertical(StackHorizontal(v1,v2), StackHorizontal(v4,v3))
Rotate(45)

Playing this AVS file resulted in:


Using non Black background shows the more creative result orientation:

Yes, the image has to be square to use the stacking sequence in that script. In another video I used the same -45 degree pre-rotation to level the images.

I still can't upload anything!

Jagabo, seems like site has been a little weird lately here also. Slow and problems uploading. Weird thing is one of my isp path routers works ok but the other doesnt.
