H.264 vs H.265 vs AV1: which video codec should you use?
Compare H.264, H.265, and AV1 for playback compatibility, compression efficiency, and encoding time, then choose a verified encoder in Burger Compress.
Start with H.264 when compatibility comes first. Compare H.265 or AV1 for higher compression efficiency, and always test playback on the actual destination.
H.264 vs H.265 vs AV1 comparison
Narrow the choice by destination, then verify it with the same original sample. This table gives selection guidance, not compression percentages or speed rankings without test conditions.
| Codec | A useful starting scenario | Verify first |
|---|---|---|
| H.264 | Sharing, presentations, and workflows including older devices | Supported container and audio codec |
| H.265 / HEVC | HEVC-capable recipients and a size/quality comparison | Operating system, player, browser, and editor support |
| AV1 | AV1-capable recipients with time to test encoding | Encoder availability, processing time, and destination playback |
H.264, H.265, or AV1: the short answer
H.264 is usually a practical starting point when a video must play across many devices, players, or websites. H.265 and AV1 are worth comparing when smaller output at similar visual quality matters more, but encoding time, hardware support, and playback compatibility vary by device and platform.
No codec is best for every video. Check the publishing platform's requirements, then encode the same short source sample and compare file size, picture, processing time, and playback on the destination device.
MP4 and MKV are not video codecs
MP4 and MKV are containers. H.264, H.265 (HEVC), and AV1 are video codecs. A container holds video, audio, and other streams, while a codec determines how the video data is compressed.
Exporting MP4 alone does not establish compatibility. The destination must also support the video and audio codecs inside it. Check the container, video codec, and audio codec together.
H.264: start with broad compatibility
H.264 is widely used and is often suitable for sharing, presentations, web playback, and workflows that must include older devices. When a platform has no special requirement, MP4 with H.264 and a common audio codec is a practical combination to test.
Compared with newer codecs, some content and settings may need a higher bitrate for a similar visual result. The difference depends on the source, encoder, and settings, so a single fixed saving does not describe every file.
H.265 (HEVC): consider newer destinations
H.265 is commonly considered when you want better compression efficiency and the receiving device explicitly supports HEVC. It can be a candidate for higher-resolution video or archive copies, but measure the result with your source material.
Before sharing or uploading, verify support in the recipient's operating system, browser, editor, and publishing platform. Playback on your own computer does not guarantee playback everywhere.
AV1: verify time and destination support
AV1 is another option for compression efficiency. It is worth comparing when the destination already supports AV1 and the task can allow more encoding time. Performance can differ substantially across computers.
Do not assume that a newer codec fits every workflow. Test a short sample for encoding time, file size, and picture quality, then verify it in the real player or platform.
Choose a codec in Burger Compress
After importing a video and choosing compression, review the video-codec options. Burger Compress includes baseline software encoding capabilities. Hardware encoders become selectable only after they pass capability checks on the current computer.
- Confirm the destination's supported container, video codec, and audio codec.
- Start from a built-in preset and change only the codec you want to compare.
- Encode a representative short sample.
- Compare size, picture, processing time, and destination playback before processing the full video.
Common questions
Is H.265 always smaller than H.264? No. A useful comparison needs the same source, reasonable settings, and a similar visual target.
Does AV1 always have the best quality? That is too absolute. The encoder, settings, material, and viewing conditions all affect the result. Compatibility and processing time matter alongside file size.
