Choosing a video codec affects file size, quality, editing performance and whether your audience can play the file at all. Here is how the three major options differ in 2026.
H.264 (AVC)
H.264 is the universal standard. Every phone, TV, browser and editing app plays H.264 in MP4 with minimal fuss. Compression is less efficient than newer codecs, so files are larger at the same visible quality — but compatibility wins for client deliverables, email attachments and older hardware.
HandBrake's x264 encoder with RF 20–22 produces excellent 1080p results. See the best settings guide for tuning. When comparing tools, H.264 support is baseline across HandBrake, FFmpeg and VLC.
H.265 (HEVC)
H.265 delivers roughly 40–50% smaller files than H.264 at equivalent quality — ideal for 4K archiving and Apple-centric workflows. Licensing and hardware decode support remain uneven on budget Android devices and some browsers. Our 4K HEVC guide covers HandBrake-specific RF targets; the hardware acceleration article explains NVENC HEVC for speed.
Convert HEVC only when you know the playback chain supports it, or offer an H.264 fallback encoded via the MKV to MP4 tutorial workflow.
AV1
AV1 is the royalty-free successor with excellent efficiency, adopted by YouTube and Netflix for streaming at scale. Software AV1 encoding is slow; newer GPUs add AV1 hardware encode and decode. Use AV1 when targeting modern platforms that explicitly support it — not for universal client USB sticks.
HandBrake includes AV1 software encoders for experimenters willing to wait. For day-to-day work, H.264 and H.265 remain the practical pairings with our YouTube export settings and compression tutorial.
Practical recommendations
YouTube uploads: H.264 or H.265 — YouTube re-encodes anyway, so feed high-quality source as documented in our YouTube tutorial. Long-term archive: H.265 or AV1 with software encoding and slow presets. Maximum compatibility: H.264 in MP4 with AAC audio, as used in the MOV to MP4 guide and iPhone video tutorial.

Editing and playback performance
H.264 is easiest on editors and older laptops during timeline scrubbing. H.265 and especially AV1 stress weaker machines unless you generate editing proxies. HandBrake can produce those proxies with Quick Sync or NVENC while you sleep. Streaming platforms transcode regardless, but archival masters should use the most efficient codec your playback chain supports — often H.265 in 2026, with H.264 fallbacks on USB sticks for clients.
