MP4ART(1)

💖 MP4ART — the manual page, but make it a group chat 💖

okay bestie, so this is the manual page for mp4art, and it lives in the MP4v2 Utilities family. version? mp4art trunk-r507. we're doing album art today. it's giving very much "cover art glow-up" energy and I am obsessed. ✨

✨ SYNOPSIS ✨

mp4art [OPTION]... ACTION file...

that's the whole vibe right there: options, then an ACTION, then your files. periodt. 🎀

---

🦋 DESCRIPTION 🦋

for every single mp4 (or m4a, we love an m4a) file you hand over, it does the ACTION you asked for. that's it, that's the job. 💅

but listen — an action must be specified. no action, no party. and some options just aren't applicable for some actions, so don't be out here mixing and matching like it's a build-your-own-bowl situation. 🙈

---

🎀 ACTIONS 🎀

this is the main character section. pick one. 👑

• --list — list all covr-boxes. show me what we're working with. ✨
• --add IMG — add a covr-box from the IMG file. new art, who dis? 🖼️
• --replace IMG — replace the covr-box with the IMG file. out with the old, in with the slay. 🔥
• --remove — remove the covr-box. bye bestie, you're not coming to the function. 💀
• --extract — extract the covr-box. get it outta there. 📤

---

🌸 ACTION PARAMETERS 🌸

the lil modifiers that tell the action which covr-box to touch.

• --art-any — act on all covr-boxes. this is the default, so if you don't say anything, it says everything. 🌈
• --art-index IDX — act on covr-box index IDX. specific queen behavior, we love a targeted approach. 🎯

---

💅 OPTIONS 💅

okay here's the whole menu, no skips, no cuts. 🍓

• -z, --optimize — optimize the mp4 file after modification. post-glow-up skincare routine. 🧖
• -y, --dryrun — do not actually create or modify any files. window shopping only, no checkout. 🛍️
• -k, --keepgoing — continue batch processing even after errors. falling down but getting back up, we love resilience. 🫶
• -o, --overwrite — overwrite existing files when creating. no hesitation, no flinching. ⚡
• -f, --force — force overwrite even if the file is read-only. oh she's loud loud. use with intention. 😭
• -q, --quiet — equivalent to --verbose 0. shhh era. 🤫
• -d, --debug NUM — increase debug, or use the long-option to set NUM. 🐛
• -v, --verbose NUM — increase verbosity, or use the long-option to set NUM. yap mode, adjustable. 🗣️
• -h, --help — print brief help, or use the long-option for extended help. ask and you shall receive. 📖
• --version — print version information and exit. then it dips. 👋

---

🐛 DEBUG LEVELS 🐛

(for raw mp4 file I/O, iykyk)

• 0 — supressed
• 1 — add warnings and errors (default)
• 2 — add table details
• 3 — add implicits
• 4 — everything

---

📢 VERBOSE LEVELS 📢

• 0 — warnings and errors
• 1 — normal informative messages (default)
• 2 — more informative messages
• 3 — everything

---

quick vibe check bestie: -f, --force is literally described as forcing the overwrite even if the file is read-only. that's real power, so point it at the right files, mkay? 💖

---
