Apple TV 4K natively hardware-decodes H.265 (HEVC), H.264, and AV1. HEVC is Apple's preferred format for high-quality 4K and 1080p content — it delivers the same visual quality as H.264 at roughly 40% smaller file sizes, making it ideal for local media servers (Plex, Jellyfin, Infuse) that stream to Apple TV. Encoding to H.265 MP4 gives Apple TV hardware-accelerated playback and leaves less footprint on your NAS or media server storage.

Apple TV supports H.264, H.265 (HEVC), and AV1 (4K model only). For best compatibility with the built-in TV app and Plex/Infuse without transcoding, use H.265 MP4 or MKV. H.264 is also fine but produces larger files.
Yes. All Apple TV 4K models (1st generation 2017 and later) hardware-decode H.265. This means zero transcoding overhead — smooth 1080p and 4K playback without CPU strain on your media server.
H.265 produces files 30–40% smaller than H.264 at equal quality. Smaller files reduce NAS storage requirements and network bandwidth when streaming over Wi-Fi. Apple TV hardware-decodes both equally efficiently.
Infuse (by Firecore), Plex, and Jellyfin are the most popular media server apps on Apple TV. All three direct-play H.265 MP4 and MKV files on Apple TV 4K without transcoding, provided the audio is also compatible (AAC, AC-3).
Apple TV 4K (3rd generation, 2022 model) added AV1 hardware decode. Earlier Apple TV 4K models and Apple TV HD do not support AV1. H.265 MP4 is the universal HEVC format that plays on all Apple TV 4K models.
The public encoder is useful for quick previews. For larger files, up to 8K/120fps output, bulk jobs, API access, storage outputs, and webhooks, create an account and run production workflows with predictable NEU estimates.
