What is the MP4 Format?
MP4 (MPEG-4 Part 14) is the most widely used digital multimedia container format today. It's known for its excellent balance of video quality, compression (resulting in smaller file sizes), and universal compatibility across devices, platforms (Windows, Mac, Android, iOS), and web browsers. It commonly uses H.264 or H.265 (HEVC) video codecs and AAC audio.
Advantages:
- High Compatibility
- Good Compression
- Web-Friendly
- Supports Subtitles/Metadata
Considerations:
- Lossy Compression (usually)
- Can be complex with different codecs
