Rather than just describing the disc specs, I’ll develop a short story based on that prompt — imagining the behind-the-scenes drama of authoring that very Blu-ray. The 25GB President

Marco stared at the timeline. El Presidente , Season 1 — all eight episodes. Raw master files: 48.7 GB. Target disc: BD25, max capacity 23.3 GB usable space after menus and extras.

Then he saw it: episodes 4, 5, and 6 had dark, grainy night scenes. Perfect for aggressive compression. He tweaked the encoder's constant rate factor from 18 to 22 — a heavy loss, but invisible to most viewers. Or so he told himself.

It sounds like you're referring to on a BD25 (Blu-ray disc with 25GB capacity).

Marco tried everything. Re-encoded the 5.1 audio to Dolby Digital at 448 kbps instead of lossless — saved 800 MB. Dropped the Spanish commentary track entirely. Lowered menu video to 720p. Still, he was 4 GB over.

At 3 a.m., the disc image built successfully. He burned a test BD25. Playback on his reference monitor looked… fine. Slight macroblocking in episode 5's coup scene, but only if you paused.
