You may have installed ffmpeg but its likely you haven't installed it in the correct location or paired with the right version. It can get a bit disorienting because when you install stability matrix, it will create a local installation of python, pip, and other modules that are separate from your main installation on your computer, especially with windows. So if you installed python separately from Stable diffusion which is Python 3.12 for the latest release direct from pythons website, but stability matrix has a version of python 3.10 which it installed itself during installation, that already tells you they are separate installation locations.

There are several different methods online to install ffmpeg and it can get a bit tricky. The easiest is a pip or get command. Instructions and tutorials can be found on the internet via a quick google search but keep in mind the different installation locations.

For me the solution was (but I'm using a1111 stable diffusion web ui:

Download the install zip folder direct from ffmpeg, look for the "full build"
Once you unzip the package put it directly into the root of "stable diffusion web ui"
mine is D:\Stability Matrix\Data\Packages\Stable Diffusion WebUI
put the three files from the zip directly into the root and I no longer get an ffmpeg error so it should be properly installed.

Try this process but put it in the root of comfy ui's package folder and see what happens and report back.
