how to splice videos?

[SignedupGuest]

Anyone know if its possible to splice two videos into a single video?

In other words, take videos with the same height, and play them side by side (the width of the final video would be sum of the width of the two source videos).

Example:
Video 1: 100x500
Video 2: 150x500
Videos spliced: 250x500.

Preferably some relatively easy solution in VirtualDub? But I can also dust off Sony Vegas if needed.

In Vegas, look for Track Motion in the help.

AVISynth STACKHORIZONTAL() is indeed a very quick and high quality way to do this. But for the benefit of others who may not be well versed in AVISynth, any NLE can do this.
Just set your timeline/project settings for the expected output resolution. In this case, it would have been 250x500.
Then, you import your footage - without resizing.
Then put them on multiple layers in the timeline and reposition them - one to the leftmost and one to the rightmost (without changing thier vertical position).
Then, output/render.
