For this effect, you will need a latest build of FFmpeg installed and a 32-bit version of Audacity running on your operating system, such as Windows, macOS, or a certain Linux desktop environment.

Step 1: Prepare Your Terminal

If you're running on Windows, you can use Windows Command Prompt, Powershell, or Git Bash to run FFmpeg. If you have not installed it yet, then you should get it from the official FFmpeg website and download it if necessary. If you're running on macOS, you can run FFmpeg using its built-in terminal, or alternative terminal emulator apps such as iTerm2, Warp, or Alacritty. You must install the package manager Homebrew in order for it to get FFmpeg installed to your computer, and when you are done, test it out to see if it works. If you are running on Linux, you can use any default terminal emulator built into your distribution, like GNOME Terminal, Konsole, Alacritty, Kitty, or Xterm.

Step 2: Applying a Crunchy Audio Effect

Start opening up the Audacity app or use a terminal to launch Audacity by using your Linux distribution's package manager if already installed. Next, you will import your file there in the application, and launch the Decimator (decimator_1202) plugin. Inside the plugin, you will set the bit depth to 5, and the sample rate (Hz) to 10000, and apply the result to your chosen file now. Export your audio in any format and preferences, and it should be already saved into your files.

Step 3: Applying a Crispy Video Effect

Launch FFmpeg and type the script down below and start entering it:

ffmpeg -i input.ogv -filter_complex "amplify=radius=30:factor=1000:threshold=10:tolerance=0:low=100:high=300:planes=7,exposure=exposure=2:black=0" output.ogv

Once you have completed rendering the result, your video should look exactly like how it's applied:

Step 4: Merging the Files Altogether

You can use any video editor to merge both the audio effect and the video effect output files to match the result and you would render it and it will go straight to your files.

Step 5: Preview and Upload

Once you've done that, preview your video and upload it to YouTube, Dailymotion, Vimeo, Odysee, Rumble, VidLii, or any other video hosting website you want to put there.
