How to join two videos in the same window?

[bgeorgalas]

Hi everyone,
2 questions for you:
1. does anyone know a way of joining/merging two video files in the same window?
I would like to create one video file in which the screen is divided in two parts (upper/lower) and put different video files in each one.....
2. I would like to create a video file underneath which is a running audio spectrogram/audio window....any ideas of which program to use?

Please see the attached photographs. I need to create a video file containing the above so please do not suggest the use of some media player....

Thank you in advance for your time and i apologize for the quality of my english.
I can work both in windows and in ubuntu (basic user).

thanx again for your time!

You can use avisynth, see https://forum.videohelp.com/topic354183.html#1897540

There is an Avisynth filter called AudioGraph that might work for you.

There is also a script called jdl-wrappers.avsi to show both channels in a stereo file. You save the script to your Avisynth Plugins folder.

Here's an image of a test I did with Audiograph, and then using the AudioGraphWrapper script.






I used 3 Avisynth scripts to generate the AudioGraph sample, in order they are

Otway.avs

audio=DirectShowSource("C:\path\It's Not Unusual.mpg")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\AudGraph.dll")
return AudioGraph(AudioDub(BlankClip(length=4980, width=352, height=50, fps=25), audio), 0)
ConvertToRGB32()

OtwayAudiograph.avs

v1=DirectshowSource("C:\path\It's Not Unusual.mpg", audio=true).ConvertToRGB32()
v2=AVISource("C:\path\Otway.avs")
StackVertical(v1, v2)

and the final Combined.avs

v1=DirectshowSource("C:\path\Johnny_Was.AVI").ConvertToRGB32().LanczosResize(3 52,338)
v2=AVISource("C:\path\OtwayAudiograph.avs")
StackVertical(v1, v2)

The ConvertToRGB32 is in the scripts because of video format differences between the two clips, might not be necessary with your source videos.

For the Audiographwrapper sample, I just needed two scripts since Audiographwrapper combines the video and graph automatically. I did change the default script to give a height of 25 pixels for each channel instead of the default 100 so that I could match the first sample output resolution.

The scripts for this one are:-

Otway2.avs

DirectShowSource("C:path\It's Not Unusual.mpg")
LoadPlugin("C:\Program Files\AviSynth 2.5\plugins\AudGraph.dll")
AudioGraphwrapper(0)

and Combined2.avs

v1=DirectshowSource("C:\path\Johnny_Was.AVI", audio=false).LanczosResize(352,338)
v2=AVISource("C:\path\otway2.avs")
audio=AVISource("C:\path\otway2.avs")
StackVertical(v1, v2).Audiodub (audio)

I had to add the Audio and Audiodub lines in this script to get the correct audio to work.

Hope this helps, was fun figuring it out!

That worked perfectly!!!!

Thank you very much for your time and patience!!!!!
