First, the components: "Fallout 2024" probably refers to the post-apocalyptic game series Fallout, but the title here is "Fallout 2024". The "S01" might indicate season one, like a TV series, and "480p webDL" is a video resolution and source. The date "2021" might be the year it was released or added, though that's odd since 2021 is earlier than 2024. There's a username mentioned: "movies4uvip".
