What is MP4?

MP4 (MPEG-4 Part 14) is the industry standard video format, offering excellent quality at reasonable file sizes for web and mobile playback.

What is HEVC?

Raw H.265/HEVC is an elementary stream of High Efficiency Video Coding data, doubling compression efficiency over H.264.

When Should You Use MP4 vs HEVC?

Use MP4 When...

Reach for MP4 when your priority is streaming, mobile video, online platforms — its efficient compression makes sharing fast and storage minimal.

Use HEVC When...

Reach for HEVC when your priority is high-efficiency video encoding, 4k/8k streams — its efficient compression makes sharing fast and storage minimal.

MP4 vs HEVC: Key Differences

  • •MP4 uses lossy compression while HEVC uses lossy compression — both take the same approach to file size management.
  • •Since both MP4 and HEVC use lossy compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
  • •Transparency: N/A
  • •Storage footprint: 1MB/min (720p) to 10MB/min (4K) for MP4 vs 50% smaller than H.264 at same quality for HEVC.
  • •MP4 is optimized for streaming, mobile video, online platforms while HEVC is designed for high-efficiency video encoding, 4k/8k streams — choose based on your specific workflow needs

Advantages of MP4

  • ✓MP4 uses lossy compression tailored for Streaming, mobile video, online platforms.
  • ✓MP4 is supported natively on virtually every device, browser, and operating system.
  • ✓MP4 files are compact and quick to transfer, even over slow connections.
  • ✓MP4 integrates seamlessly with all major creative tools and workflows.

Advantages of HEVC

  • ✓The lossy nature of HEVC means file sizes stay reasonable while handling High-efficiency video encoding, 4K/8K streams efficiently.
  • ✓From mobile devices to enterprise servers, HEVC is recognized and supported everywhere.
  • ✓Storage and bandwidth costs drop significantly when using HEVC thanks to its efficient compression.
  • ✓HEVC is a first-class citizen in all major software ecosystems, from creative suites to development environments.

Troubleshooting MP4 to HEVC Conversion

  • !HEVC won't play on target device → check codec compatibility (H.264 has broadest support)
  • !Audio out of sync after MP4 to HEVC conversion → try re-muxing with a different container format
  • !HEVC quality is too low → increase the bitrate; for 1080p video, 8-15 Mbps is recommended
  • !File size increased converting MP4 to HEVC → lossless or higher-bitrate outputs naturally produce larger files
