When exporting video files from Premiere Pro, DaVinci Resolve, or CapCut, your export settings confront you with an immediate technical choice: H.264, HEVC (H.265), or AV1.
Choose the wrong codec, and your video might fail to play on older iPhones, take four times longer to encode, or chew through twice the storage bandwidth for the identical visual quality.
🎬 Compress Any MP4 or MOV Video Locally
Crate Video Compressor uses in-browser FFmpeg WebAssembly to shrink MP4 videos up to 85% with zero quality loss and complete client-side privacy.

| Codec | Relative Bitrate for Equal Quality | Hardware Decoding | Licensing / Royalty |
|---|---|---|---|
| H.264 (AVC) | 100% (Baseline) | 99.9% of all devices worldwide | MPEG-LA Patent Pool |
| H.265 (HEVC) | ~60% (40% smaller than H.264) | 90%+ modern phones & GPUs | Complex, expensive patent pools |
| AV1 (AOMedia) | ~45% (55% smaller than H.264) | Growing (RTX 30+, Apple M3+, modern phones) | 100% Open-Source & Royalty-Free |
1. H.264 (AVC): The Universal Workhorse
Released in 2003, H.264 is the most ubiquitous video standard in technological history. Every smart toaster, decade-old television, cheap budget phone, and social media platform contains dedicated silicon microchips designed to hardware-decode H.264 with near-zero battery drain.
When to use H.264: For client delivery, email attachments, Discord uploads, and final web deliverables where guaranteed playback on every conceivable device is mandatory.
2. HEVC (H.265): The 4K HDR Camera Standard
HEVC was designed to solve the data explosion of 4K and 8K video. By expanding macroblock sizes up to 64×64 pixels (compared to H.264's 16×16), HEVC cuts file size in half without degrading sharpness.
However, HEVC was crippled by proprietary patent disputes between multiple licensing pools. As a result, web browsers like Google Chrome refused to natively support HEVC playback for nearly a decade, limiting its use primarily to camera capture (iPhones, Sony FX3, DJI drones).
3. AV1: The Open-Source Future of Streaming
Frustrated by HEVC licensing fees, a coalition of tech giants—including Google, Apple, Netflix, Amazon, Meta, and Microsoft—founded the Alliance for Open Media (AOMedia) to create AV1.
AV1 delivers unmatched compression efficiency, beating HEVC by 20% to 30%. YouTube, Netflix, and Twitch now serve billions of streams in AV1 to save millions in global server bandwidth. While software encoding was initially slow, modern GPUs now support blazing-fast hardware AV1 rendering.
