It’ll also error out or prompt to overwrite an existing file unless a flag is passed that tells it to overwrite unattended.

Sure, but if it errors out no harm no foul, and don’t pass any flags to overwrite the input file which I had not included above.

While I’m thinking about it, what is that flag? Because afaik ffmpeg can’t overwrite and convert the file simultaneously, you have to use a temp file.

That’s the point: you have to go out of your way to accidentally overwrite your input files with ffmpeg.

And no it indeed can’t output to the same file as input.
