File Size & Compression

MP4 Compression

MP4 uses efficient compression algorithms, particularly H.264 and H.265 (HEVC), which deliver excellent video quality at smaller file sizes. This makes MP4 the preferred format for web streaming, social media, and mobile devices.

  • Highly efficient H.264/H.265 compression
  • Optimized for streaming and web delivery
  • Smaller file sizes without quality loss
  • Better bandwidth efficiency for online video
  • Ideal for storage-constrained environments
Advantage: MP4's superior compression makes it perfect for sharing videos online and reducing storage costs.

MOV Compression

MOV supports various codecs including Apple ProRes, which prioritizes quality over file size. While this results in larger files, it's preferred for professional video editing where quality preservation is paramount.

  • Supports high-quality codecs like ProRes
  • Less compression for professional workflows
  • Larger file sizes preserve editing quality
  • Better for post-production and effects
  • Optimized for Apple's editing ecosystem
Note: MOV files can be significantly larger than MP4, especially when using uncompressed or lightly compressed codecs.

Frequently Asked Questions

Not necessarily. Both formats are containers that can hold the same codecs. Quality depends on the codec and bitrate used, not the container format. MOV often contains higher quality codecs like ProRes, while MP4 typically uses H.264/H.265. At the same codec and bitrate, quality is identical.

Yes, but it may require additional software. Windows 10/11 has basic MOV support, but some codecs may not play. Installing VLC Media Player or converting MOV to MP4 ensures reliable playback. For professional work, codec packs or QuickTime for Windows can help.

MP4 is better for YouTube. While YouTube accepts both formats, MP4 with H.264 codec is recommended by YouTube for optimal processing, faster upload, and better streaming performance. MP4 files also upload faster due to smaller file sizes.

It depends on the conversion settings. If you transcode to a different codec or lower bitrate, some quality loss may occur. However, if you simply rewrap the video stream without re-encoding (when codecs are compatible), there's no quality loss. Using high-quality settings minimizes any degradation.

iPhones record in MOV format because it's Apple's native format, optimized for the Apple ecosystem. MOV provides excellent quality and seamless integration with macOS and iOS apps. However, newer iPhones can record in MP4 format if configured in settings for better cross-platform compatibility.

MP4 typically takes up less space because it's optimized for compression and web delivery. MOV files, especially those using ProRes or other professional codecs, are larger because they prioritize quality over file size. For the same codec and settings, file sizes are similar.
