Convert Mov or any video format to mp4

[Yerinnie]

I'm downloading videos from Kemono, but some of them are in the MOV format. How can I (with ffmpeg?) convert it to mp4. I did find something about postprocessing, but I'm not sure how to convert it.

    "postprocessors": [
        {
            "name": "exec",
            "filter": "extension in ('mov', 'webm', 'mkv')",
            "command": [
                "ffmpeg",
                "-i"  , "{_path}",
                "-crf", "20",
                "-f"  , "mp4",
                "\fF {_path.rpartition('.')[0]}.mp4"
            ]
        }
    ]

Adjust the FFmpeg options as you see fit (-crf 20).

You need to add another exec post processor to delete to old video, by the way. Something like

        {
            "name": "exec",
            "command": "rm -- {}"
        }

The converting is working but deleting the old video not (using windows)

Error:

Try disabling path-extended.
I'm kind of surprised there even is an rm on Windows.

Also, you should use the same filter for the delete command as for the FFmpeg one, otherwise it will delete all files.

Yes, disabling path-extended fixed it.

As for rm, I use bash on Windows which have the rm command

Also PowerShell has rm, if as an alias to Delete-Item.
