HEVC/x265 is being superseded by , which offers up to 30% better compression than HEVC. Already, groups like PSA have started releasing AV1 encodes (though not yet for Silo S02). AV1 10‑bit at 720p can produce watchable files as small as 100 MB per episode . However, hardware support is still limited to newer devices (Intel Arc, AMD RDNA3, Nvidia RTX 40 series, and some smartphones).
While files like "Silo.S02.720p.10bit.WEBRip.2CH.x265.HEVC-PSA.zi..." offer numerous benefits, their distribution and consumption also come with challenges and controversies:
This article explores what to expect from the second season of Silo and breaks down the technical aspects of this popular release format. What is Silo Season 2 About?
Look out for Steve Zahn as "Solo," a key new character Juliette meets in the vault of the abandoned silo. Silo.S02.720p.10bit.WEBRip.2CH.x265.HEVC-PSA.zi...
PSA typically targets 1–1.5 Mbps for 720p and 2–3 Mbps for 1080p, which is roughly half of what many x264 releases use. The result: a 45‑minute episode of Silo sits at ~350 MB instead of 800 MB. For a full 10‑episode season, that’s 3.5 GB vs. 8 GB – a huge saving for Plex servers or limited monthly data.
Based on Hugh Howey's Wool trilogy, the show continues to expand on the claustrophobic and deeply atmospheric world-building that made the first season a massive success on Apple TV+.
Due to the advanced math behind HEVC compression, older hardware may struggle to decode these files efficiently. Optimal playback requires specific software and hardware considerations: HEVC/x265 is being superseded by , which offers
This will produce a file comparable to PSA releases, though their exact settings are proprietary (they likely use tuned grain or custom quantization matrices).
: Signifies the audio layout. "2CH" stands for two-channel audio, commonly known as Stereo (Left and Right channels), which is ideal for standard television speakers and headphones.
: Indicates a 10-bit color depth. Standard video uses 8-bit color (16.7 million colors), which often results in "color banding" in dark gradients or shadows. A 10-bit encode supports over 1.07 billion colors, ensuring smooth gradients and superior shadow detail—a critical feature for a dark, subterranean show like Silo . However, hardware support is still limited to newer
: Refers to the video resolution. 720p is a high-definition (HD) resolution standard with 1280 pixels horizontally and 720 pixels vertically.
: This refers to the video encoding standard used, specifically H.265 (also known as HEVC, High Efficiency Video Coding). The x265 encoding is known for its efficiency in compressing video files, allowing for smaller file sizes without a significant loss in quality. This makes it highly sought after for file sharing and streaming.
