FFmpeg GUI or software for put videos side-by-side?

[Unknown01]

Basically, what i want to do is make 2 video fragments display like this:



Or like this:




I heard FFmpeg can do this, but i can't find a good GUI that provides this utility and the command window is too confusing to use.

I would prefer free software instead of those limited/watermarked softwares.

Tried Avanti but it doesn't seem to be able to do that. I also tried other FFmpeg GUIs that were better but they weren't free and had trial/watermark limitations.

Very easily accomplished in FFmpeg. Where input0 and input1 are your two sources, and output is the output file, to stack vertically:

ffmpeg -i input0 -i input1 -filter_complex vstack output

To stack horizontally:

ffmpeg -i input0 -i input1 -filter_complex hstack output

Ah, that's wonderful.

But...is there a way to make FFMPEG not normalize the Frames-per-second?

I have 2 videos, 1 in 60FPS thanks to SVP and one at normal 24~30FPS.

If put them side-by-side via FFMPEG, it will end as a 24~30fps video.

You can add the -r option after the inputs to force an output frame rate, e.g.

ffmpeg -i input0 -i input1 -r 60 -filter_complex vstack output

This will preserve your 60 fps and duplicate frames as necessary in the other video.

This is also easily done in any multi-track video editor. A good free one is Aviutl. You can also do it easily with Avisynth, then feed the script to your media player for preview or encoder for encoding.

Thanks for the replies!

Um, is there a way to keep only 1 in 60 FPS in ffmpeg? Because the whole reason i want to put a video side-by-side is to show the difference between frame interpolation and normal video.

Even more, using that will make 1 of the 2 videos "freeze".


Speaking of the -r 60 line, is it the same as SVP? I found that interesting.

That Aviult looks interesting.

Is there a way to "fully" download this software?

Because it seems that while installing it requires many things, and the installer caps the downloading speed at 8~15 KBPS.

My editing system isn't connected to web, so I'm still using Aviutl version 1.10. It's a self-contained portable version. Just create a new project at half the size and at the highest framerate. In your case it will be 60 fps. Then drag each video clip to a different layer and resize via Zoom @ 50%. Then move each one into position. Then render out...

When you install it for the same time it ask to install many things, at an awfully slow speed.

Either way, after 2 hours waiting it finally installed.

I have 2 questions:

1. Is there a way i can "crop" the "canvas" once i got the correct size so no black parts are left?

2. When i set the FPS after adding a video, will it affect the second one? Because it only asks once, at the start of the project and the result seem to be 2 videos at the exact same framerate.



I wanted to learn how to do so in FFMPEG, but it seems it cannot do what i ask. Oh well.

@Unknown01

A video can only have one frame rate. If you combine two clips with different frame rates, one will have to be adjusted to match.

If you want to show the difference between a 24 fps clip and a 60 fps interpolated clip, you still need to convert the 24 fps clip into 60 fps, but do it without using interpolation (just plain duplicated frames).
