What is HEVC?

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

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.

When Should You Use HEVC vs MP4?

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.

Use MP4 When...

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

HEVC vs MP4: Key Differences

  • •The core technical difference: HEVC relies on lossy compression whereas MP4 uses lossy compression.
  • •Both formats share lossy compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
  • •Alpha channel support: MP4 lacks transparency support.
  • •HEVC files are typically 50% smaller than H.264 at same quality while MP4 files range 1MB/min (720p) to 10MB/min (4K)
  • •Primary audience: HEVC is built for high-efficiency video encoding, 4k/8k streams scenarios, while MP4 focuses on streaming, mobile video, online platforms — pick the format that matches your output requirement.

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.

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.

Troubleshooting HEVC to MP4 Conversion

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