MP4 Video Not Generating : FileNotFoundError: [WinError 2] The system cannot find the file specified

I'm able to generate a .GIF, but the MP4 does not process. On the last frame I get:

Anyone else? I know FFMPEG is installed I can see it when I ask in a CMD prompt. Thanks in advance!

I was getting that error because the filepath to ffmpeg was not set correctly - it was just "ffmpeg" when it should've obviously been "C:\FFmpeg\bin" (my ffmpeg install location). But ever after setting it, I now get an "Access is Denied" error that I still cannot figure out. PATH is setup and everything.

[DarkJukeMastah]

It's really not straightforward, but you literally have to set the exe in the textbox, for example: C:\ffmpeg\bin\ffmpeg.exe

[kabachuha]

Did you manage to resolve it?

[Spritzo]

I was eventually able to get mine resolved. Just had to restart my machine a few times and it was finally able to generate videos properly with the correct PATH set.

It's a very common issue, please follow the instructions in this link if you're still having this issue.

Make sure you perform Step 3: Add FFmpeg to PATH which is the most important part.

Closing.
