✨ NAME ✨

videowmark — video watermarking tool (using audio track) 🎀

🌸 SYNOPSIS 🌸

videowmark [options] command [args...]

🦋 DESCRIPTION 🦋

so what does this girl even do? videowmark creates watermarked video files that have a whole embedded message hiding inside them, and it can also go back and retrieve an embedded message from a video you already watermarked. it's giving secret-agent energy, fr fr. 🕵️♀️

messages get handed over as hexadecimal data and they're embedded in a way that's meant to be robust against common video processing operations. like, the message survives the glow-up. slay. 💅

👑 COMMANDS 👑

  • add input_video watermarked_video message_hex — make a watermarked video file that's holding the message you gave it. iconic behaviour.
  • get watermarked_video — pull the embedded message back out of a watermarked video and print it to standard output. reading the room? no, reading the video. 🌈

💜 GLOBAL OPTIONS 💜

these apply to all the commands, no exceptions bestie.

  • --strength s — set the watermark strength. 💪
  • --key file — load the watermarking key material from file. 🔑
  • -q, --quiet — turn off informational messages. shhh. 🙈
  • -v, --verbose — turn on verbose output from the underlying ffmpeg processing. not me wanting to see everything. 😭

🌟 ARGUMENTS 🌟

  • input_video — path to the input (unwatermarked) video file. the before picture.
  • watermarked_video — path to the output (watermarked) video file (that's for add), or the input watermarked video file (that's for get). it's giving dual purpose, main character energy.
  • message_hex — the message you wanna embed, handed over as hexadecimal bytes. ⭐
