Now, the “x265” part. The H.265/HEVC (High Efficiency Video Coding) standard, implemented by the open-source encoder x265, compresses video more efficiently than the older H.264 (x264).
For a film like Mulholland Drive, x265 offers specific benefits:
| Feature | H.264 (x264) | H.265 (x265) | Impact for Mulholland Dr. | |---------|--------------|--------------|----------------------------| | Compression efficiency | Baseline | ~50% better at same quality | Smaller file size without losing shadow detail. | | Macroblock size | Up to 16x16 pixels | Up to 64x64 pixels | Reduces “blockiness” in dark sections (e.g., the alley behind Winkie’s). | | Motion estimation | Complex | More precise | Preserves the fluidity of the dolly shot through the red curtains. | | Grain retention | Poor at low bitrates | Better with tune grain settings | Film grain remains intact without excessive bitrate. | Mulholland Dr. -2001- RM4K -1080p BluRay x265 H...
A 4K remux of Mulholland Drive can exceed 50 GB. Many collectors prefer a 1080p x265 encode for a practical reason: bandwidth and storage. When done correctly (using a high-quality source like the RM4K BluRay and a well-tuned x265 encode with --preset slower or veryslow), the perceptual difference between a 25 GB 4K file and a 12 GB 1080p x265 file is minimal on standard 40–55” screens.
Moreover, Mulholland Drive was finished at 2K for its original theatrical run (digital intermediates were rare in 2001). True native 4K adds less noticeable detail compared to films shot on 65mm or modern Alexa 65. The 1080p x265 from RM4K hits a sweet spot of quality vs. file size. Now, the “x265” part
There is a poetic irony in compressing Mulholland Drive into an x265 container. The film is about copies, doubles, and degraded identities—Betty and Rita as two halves of a fractured dream. Digital compression also creates “copies” that lose something essential. Every encode is a flawed photograph of a photograph.
Lynch himself is an analog purist (he still records music on tape, and he famously used MiniDisc for Inland Empire’s lo-fi digital video). Yet he approved the 4K remaster. His philosophy: the intent of the image matters more than the substrate. A well-encoded x265 file, derived from his approved master, can carry his dream to a new generation.

The “H...” in your keyword is open-ended. It could be “HEVC” or “H.265.” But perhaps it also hints at the film’s central mystery—what lies in the blue box? What is behind Club Silencio? No codec can answer that. Only the unspeakable feeling of the film’s final 20 minutes, which no amount of compression artifacts can erase if the transfer is faithful.
