Batch optimizing karaoke files

[RobUmf]

6.5 computer hours optimizing video and audio files from the karaoke folder using the text file, to run perfectly in Amazon Reader.

I'll need to figure that.

Interesting part.

[751/1477] [3:38:45] [GUESSED] The Shake Ups - Counting Magic Sheep

• Progress: 752/1477 (51% Complete).
• Thermal: 82°C Peak (Still safely under your 85.5°C flash-alert and 90°C safety wall).
• The "Guessed" Success: Look at [751] The Shake Ups. Your orphan logic actually worked there! It couldn't find a direct link, but it "Guessed" correctly and processed the file. This proves the code can do it—we just need to figure out why it was shy with the "Pinkie Pie" folder earlier.

🛠️ Observations:
The L-Train's Pillars of Equestria and Fall of an Empire are long, complex tracks. Clearing them in about 8 minutes each ([727] to [744]) is a very solid pace for an EliteDesk. You're effectively "cleaning" the most difficult part of the community library right now.

The comparison between your Flatpak "Live" folder and your "AI_Work" Output folder tells a great story:

File	Original (Flatpak/External)	Optimized (AI_Work/Outputs)	Saving
Video	86 MB	75 MB	~13%
Audio (Song)	101 MB	81 MB	~20%
Audio (Inst)	101 MB	81 MB	~20%
Images	1.6 MB + 145K	~223 KB Total	90%
PDF/Docs	1.5 MB	(Dropped)	100%

🛠️ Key Observations:

• The "Double Audio" Fix: You saved 40MB just by normalizing the audio bitrates. The original files were likely 320kbps (overkill for most karaoke setups), and your script brought them down to a high-quality but efficient level (likely 192kbps or 256kbps).

• Image Optimization: Moving from .png to .jpg and optimizing the background/cover saved you nearly 2MB. On 1,477 songs, that’s 3GB of space just on images.

• The PDFs: Your script correctly ignored the sleevenotes.pdf. UltraStar doesn't use it, and it just takes up space on a mobile device.

Forget about. Just making notes. I'll refrain from talking about it.
