Introduction
In this article, we will discuss a solution to a common problem: how to play two videos side-by-side with different resolutions. We will explore the easiest way to do this using a grid player, as well as a more advanced solution using the mpv media player and thelavfi-complex filter.
The Easiest Solution: Grid Player
The absolute easiest way to play two videos side-by-side is to use a grid player. A grid player is a media player that allows you to play multiple videos in a grid layout. This is a great solution if you just want to quickly compare two videos without worrying about the specifics of their resolutions.
There are many grid players available, but one of the most popular is the Grid Player for Windows, Mac, and Linux. To use the Grid Player, simply download and install the software, then drag and drop your videos into the player. The player will automatically resize the videos to fit the grid, allowing you to watch them side-by-side.
The Advanced Solution: mpv Media Player and lavfi-complex Filter
If you want more control over the playback of your videos, you can use the mpv media player and thelavfi-complex filter to play two videos side-by-side with different resolutions.
First, you will need to install the mpv media player. You can find instructions for installing mpv on the mpv website.
Once you have mpv installed, you can use the following command to play two videos side-by-side with different resolutions:
mpv --lavfi-complex="[vid1][vid2]hstack" vid1.mp4 vid2.mp4
In this command, [vid1] and [vid2] are the inputs for the two videos you want to play, and hstack is the filter that stacks the videos horizontally.
To set the resolution of each video, you can use the scale filter. For example, the following command plays two videos with a resolution of 640x480 and 800x600 side-by-side:
mpv --lavfi-complex="[vid1][vid2]hstack=inputs=2:shortest=1,scale=640:-1[v1];[v1][0:v]hstack=inputs=2:shortest=1,scale=800:-1[v2]" vid1.mp4 vid2.mp4
In this command, the scale filter is applied to each video input separately, using the resolution 640x480 for vid1 and 800x600 for vid2.

The more advanced solution is to use the mpv media player and thelavfi-complex filter to have more control over the playback of your videos.
