Making a splitscreen MPEG2 video

[snowcrash]

Hello. I'm trying to compare two encoders and prove to someone that one encoding method produces higher quality video than another. So, I would like to take two MPEG2 video files and create a splitscreen video, with the left half coming from one MPEG file and the right half from the other. Does anyone happen to know how I could do this? :confused: Thank you.

Why complicating ? Start 2 players and watch it...

I suppose you could use StackHorizontal or StackVertical in aviSynth. The only advantage I see over two separate players is that you'd keep the two sources synced frame-by-frame.

You could, of course, first encode the upper part of the screen and later the bottom part. Process them in Premiere and export them in a new movie.

how about vfaping the 2 mpegs and load them into projectdivx? that's how I used to compare 2 movies side by side.. you probably have to create a dvd2avi project for the vfaping to work.. but I'm pretty sure it works
