Hacker ApprovedThe most recommended of 6 video encoders
Open, royalty-free video codec with higher compression than H.264 and H.265 and growing hardware support. Caveat: patent claims by others and heavy encoding compute remain concerns.

Each mark is one comment
Better compression than H.264 and H.265
“AV1 matches or exceeds H.265 in compression efficiency, so for greenfield projects there's little reason to reach for the legacy codecs.”
Comment from 9 Mar 2026 in “Show HN: OxiMedia – Pure Rust Reconstruction of FFmpeg and OpenCV” “AV1 delivers higher compression efficiency for 4K and 8K videos, reducing bandwidth costs without sacrificing quality.”
Comment from 12 Nov 2025 in “Video Codec Comparison: AV1 vs. H.265” “I have re-encoded H.265 to AV1 and not only gotten smaller files that playback better on low-end hardware”

What people warn about
Each mark is one comment
Patent claims still possible
“Just because AOM/Google says that wont charge a royalty doesn't mean AV1 isn't covered by patents owned by others.”
Comment from 5 Apr 2026 in “Firm boosts H.264 streaming license fees from $100k up to staggering $4.5M” “AV1’s open, royalty-free promise in question as Dolby sues Snapchat over codec”
Comment from 3 Apr 2026 in “Firm boosts H.264 streaming license fees from $100k up to staggering $4.5M” “It's only royalty free from AOM, it doesn't mean it isn't patent encumbered.”
Comment from 11 Dec 2025 in “When a video codec wins an Emmy” - Comment from 3 Apr 2026 in “Firm boosts H.264 streaming license fees from $100k up to staggering $4.5M”
Heavy compute for encoding
“AV1 is still prohibatively expensive both for the server and clients for software encoding/decoding”
Comment from 31 May 2026 in “The AV2 Video Standard Has Released (Final v1.0 Specification)” “The problem with AV1 is it requires a massive amount of compute resources.”
Comment from 8 Sep 2026 in “DaVinci Resolve 21.1” “AV1 and friends are usually too heavy in those settings”
Comment from 9 Feb 2026 in “Show HN: A luma dependent chroma compression algorithm (image compression)” Weak support on low-power devices
“Some Sony TV's only hardware accelerate AV1 content through streaming services, and not through Blueray and USB”
Comment from 10 Dec 2025 in “When a video codec wins an Emmy” “seems its difficulty for long time to be played on low power devices hindered its adoption”
Comment from 5 Dec 2025 in “Netflix’s AV1 Journey: From Android to TVs and Beyond” “the majority of devices still don't have AV1 hardware decoding support”
Comment from 3 Apr 2026 in “Firm boosts H.264 streaming license fees from $100k up to staggering $4.5M” Encoder over-flattens and looks worse
“Publicly-available AV1 encoders (still) have a tendency to over-flatten anything that is low-contrast enough”
Comment from 5 Dec 2025 in “Netflix’s AV1 Journey: From Android to TVs and Beyond” “AV1 is still worse in practice than H.265 for high-fidelity (high bitrate) encoding”
Comment from 10 Dec 2025 in “When a video codec wins an Emmy” “AV1 would most likely result in slower encodes that look worse.”
