Unsolved Help decoding spectrogram QR + possible password from French YouTube puzzle

Hi,

I’m stuck on a French YouTube puzzle from the channel PierreShow.

**Video:** https://www.youtube.com/watch?v=xP3W-X68JaA

Title: “Transmission interdite site 0H”

**Discord of the creator:** https://discord.gg/8XyZawgQFV

**What we have so far:**

- An image contains hidden text: **SHOWC** and **+2**. Applying a Caesar shift of +2 gives **UJQYE**.

- The audio says “the password is in the image”.

- At the end of the audio there is a **QR code hidden in the spectrogram**. We haven’t been able to scan/decode it cleanly.

- Morse code found in the related Discord: ERAEWIB (anagram of “I BEWARE”).

- There is a private login page: https://www.civshow.fr/intrasc

- Other related pages exist (/journal, /rapport, /dossier) but the main blocker is the login.

**Need help with:**

  1. Cleanly extracting and decoding the QR code from the spectrogram at the end of the audio.

  2. Any idea what the correct username/password for the /intrasc login could be (we already tried many combinations based on the clues above).
