If you grabbed the episode from private trackers or Usenet, you probably noticed the file size sits around 250MB–450MB for 720p, or 800MB–1.2GB for 1080p. That’s the sweet spot for H264.

Unless you are archiving the entire DCU for a personal Plex server, H265 (HEVC) offers smaller file sizes but requires more CPU power to decode. For a single episode you’ll watch once or twice, H264 is the goldilocks codec: small enough to download fast, large enough to look great on a 55-inch TV.

It serves as a narrative turning point for the seven-episode first season , establishing the stakes for the series' conclusion and the broader DCU.

Lesser codecs (like older Xvid or poorly compressed HEVC) struggle with these elements, creating "blocking" or "banding" in the shadows. H264, when encoded properly, handles this chaos with grace. It preserves the hand-drawn grit of the 2D flashbacks while keeping the 3D rendered action of the present timeline crisp.
