Combining 2 Videos into 1 file with two windows?

[201flyer]

Hypothetical question. Is it possible in any program to combine 2 videos into one file that will display both videos at the same time....not merged, but basically a single video file that has essentially two separate windows with one video playing in each window. This may not be clear! If I have two avi files 640 x 480 I would like to create a video that is 1280x480 (or 640x960). Strange, I realize!!!

Thanks for any input.

Advanced editors supports this and AViSYNTH, install avisynth and make a video.avs text file with just

StackHorizontal(AviSource("c:\folder\video1.avi"), AviSource("c:\folder\video2.avi"))

and open the video.avs in virtualdub and convert it. Or just open the .avs in Windows Media Player or Media Player Classic to play it.

(Replace the c:\folder\video1.avi with your video files location and if you get problems try replace AviSource with DirectShowSource).

In Cyberlink Video Director you can have 2 different videos playing next too each other like a split screen by using overlays. They call them PIPs but they are basically overlays so any program that allows overlays should be able to do it as well.

I also used to do it in IMovie all the time when I was creating a weekly TV show.

Thanks so much for both suggestions!!

I was able to use AVISYNTH and this worked great! I could display both videos simultaneously stacked vertically or horizontally.

I am having a problem using Virtualdub. My original 2 .avi files total only 210 MB*. When I run Vdub, direct stream, save .avi I get a huge file on the order of 10 GB. I have also tried full processing mode, Microsoft Video1 codec, and also generate a huge file. I'm obviously not very familiar with using VDub to recompress avi files....basically I've only used it for cutting and joining. Would anyone be able to make a suggestion?

I stumbed across this just this morning: You can use MkvMerge to put two videos into one MKV file. VLC will play this by opening two windows with one video in each! The videos don't even have to be similar. They can use different frame sizes, different codecs, different frame rates, etc.

Are you processing an Avisynth script with VDub? In that case, you have to re-encode, as Avisynth delivers uncompressed video to VDub. Choose an appropriate compression within VDub before saving the output.

What if someone wanted to do the exact opposite?

I have an avi file from a track day that is one file, yet when opened in vlc pops up two windows.

when opened in windows media player, just one view.

I can barely explain this let alone ask google for help, I know NOTHING about video.

Demux the two video streams then append and remux them.

Ok, please bear with me here, Im fumbling over 11ty open browser windows trying to figure this out..


So far I read that I can demux (just found out what means) with virtualdub
however it errors out saying that I need an mpeg2 decoder.

when I search for that, google points me right back to virtualdub saying that it supports mpeg2....

stupid racekeeper.... stupid me...

I doubt your file is an AVI file. Use MediaInfo to see what type of file it really is.

Yeah, a dual-muxed avi would almost ALWAYS show as 2 separate windows (not counting 3d-aware players, or maybe when using the cineform codec).
That kind of occurence would match a stereo3d or dual-bitrate wmv...

You don't see AVI files with multiple video streams very often. Here's an example dealing with such a file:
