VAMPS(1) 💅

okay bestie, sit down, we're doing DVD recompression today ✨ this is the manual page for vamps, from the Vamps manual section 1 — and yes it's giving iconic 2009 energy 🎀

✨ NAME ✨

vamps — tool to recompress and modify the structure of a DVD 🦋

🌸 SYNOPSIS 🌸

vamps [--evaporate|-e factor] [--ps-evaporate|-E factor] [--audio|-a a-
streama-stream...] [--subpictures|-s s-stream,s-stream,...]
[--verbose|-v] [--inject|-i injections-file] [--preserve|-p]
[--ps-size|-S input-bytes] <input>output ...

💖 DESCRIPTION 💖

so, Vamps was literally written to make cheap backups of DVDs under Linux 👑

Vamps builds a wrapper around the requantizer — like a little outfit change for your video stream 🧚 — to pull the elementary MPEG2 video stream out of the DVD's program stream, feed it through the requantizer, and then pack it right back into the program stream again. the way that it round-trips?? obsessed 💅

on top of all that, Vamps lets you pick which audio and subtitle streams get copied into the output stream. that's another lil win on disk space, because the streams you don't want can just be discarded 🙈

ngl, Vamps is only a very basic tool — but it's still, like, absolutely essential for transcoding DVD videos down to a smaller size. and here's the slay: Vamps does not need to write temporary data files, which is a major advantage, no cap. Vamps is very fast. the downside? it's not capable of making DVD backups on its own. it's a supporting character, not the main character, iykyk 💀

🎀 OPTIONS 🎀

heads up bestie: for options that require an argument, each duplication will override the previous argument value. so don't stack 'em and expect both, okay? 🫶

• --evaporate, -e factor — the factor by which the embedded elementary video stream will approximately be shrunk (>=1.0) ✨
• --ps-evaporate, -E factor — the factor by which the whole program stream will approximately be shrunk (>=1.0). and bestie, listen: -e and -E are mutually exclusive — pick one, not both, fr fr 💀
• --audio, -a a-streama-stream... — select the audio streams to keep. first stream is 1 🎧
• --subpictures, -s s-streams-stream... — select the subtitle streams to keep. first stream is 1 💬
• --verbose, -v — increases the verbosity level by one. stack it, watch it go 📢
• --inject, -i injections-file — loads internal variable settings from a file so you can seamlessly continue a previous run, and writes internal variables to the file when the program terminates. if the file doesn't exist, it gets created. super useful for shrinking several parts (chapters, titles) down to a single target DVD 🌈
• --preserve, -p — preserves the numbering of audio and subtitle streams. if you call it without this option, Vamps renumbers the streams to ascending numbers starting with 1. this option disables renumbering, so the original stream numbers are kept 👑
• --ps-size, -S input-bytes — if the input for Vamps doesn't come from a file (e.g. a pipe 🚰), the size of the full input program stream MUST be supplied on the command line. size is in bytes. like, must must. no vibes-based guessing here 🙅‍♀️
