Why Convert to MP4 Format?
MP4 is the most widely supported video format today, with excellent compatibility, high compression ratio, and small file size. Compared to other formats like AVI, MKV, and FLV, MP4 can play on all devices, including iPhones, Android phones, tablets, and smart TVs. Converting videos to MP4 format solves playback compatibility issues and significantly reduces file size.

How Video Conversion Works
Video conversion involves the following steps:
- Decoding: Reads the original video file and extracts video stream, audio stream, and other metadata
- Processing: Adjusts parameters like resolution, frame rate, and bit rate as needed
- Encoding: Encodes using the target format's encoder (e.g., H.264)
- Muxing: Combines video stream, audio stream, and subtitles into the final file
Conversion Tips and Considerations
Maintain Quality While Reducing File Size
- Use H.265 encoding (HEVC): 30-50% smaller file size than H.264
- Adjust bit rate: Balance quality and file size according to your needs
- Lower resolution: Reduce to 720p or 480p if only viewed on mobile devices
- Remove unnecessary audio tracks: Delete superfluous languages or audio tracks
About Source Files
- Better source video files result in better conversion quality
- Avoid multiple conversions; each conversion loses some quality
- Source files should be high bit rate encoded versions
