One is the compatibility champion. The other is usually more efficient. The right choice depends on where your video needs to go.
H.264: easier, safer, everywhere.
H.265: smaller files, heavier workflow.
| Feature | H.264 / AVC | H.265 / HEVC |
|---|---|---|
| Compatibility | Excellent. Supported almost everywhere. | Good, but less universal than H.264. |
| Compression efficiency | Good. | Usually better, often with smaller files at similar quality. |
| Encoding speed | Generally faster and easier to work with. | Usually slower and more demanding. |
H.264 is the safe default. H.265 is the efficiency upgrade when your workflow can support it.
