MOV files from iPhone and QuickTime are often saved at very high bitrates. Compressing to screen-appropriate bitrates reduces size by 50-80% with no visible difference on screens.
MOV is Apple's QuickTime format — the default for iPhone recordings, Mac screen captures, and Final Cut exports. MOV files are often saved at bitrates far higher than needed for screen viewing. Compressing to screen-appropriate bitrates reduces size by 50-80% with no visible difference.
| Input format | MOV (QuickTime) |
| Output format | MOV (H.264 + AAC) |
| Typical reduction | 50-80% |
| Resolution | Preserved or downsampled |
| Encoder | libx264 |
| Audio | AAC at 128 kbps |
| Max file size | 500 MB per file |
| File retention | Auto-deleted after compression |
The compressor decodes the MOV video and re-encodes it at a lower bitrate using H.264. Resolution is preserved (or downsampled for the target size). Audio is preserved at AAC 128 kbps. Output is a smaller MOV that plays on Mac and iOS.
At Medium (720p, 2 Mbps), most MOV videos look identical to the original on screens. Higher compression levels reduce resolution visibly on large screens but are fine for mobile viewing.
| Level | Size reduction | Best for |
|---|---|---|
| Light (1080p, 4 Mbps) | ~40-50% | Quality-preserving |
| Medium (720p, 2 Mbps) | ~60-70% | Web, sharing |
| High (720p, 1 Mbps) | ~70-80% | Email, messaging |
| Maximum (480p, 0.5 Mbps) | ~80-90% | Severe size limits |
