Tip #782: Compare Proxy Files to Source Media
Proxy files are optimized for editing and small file size.
Here’s a table that compares proxy file storage and bandwidth requirements to source media.
Keep in mind that unlike H.264, proxy files are optimized for editing. H.264 is often difficult to edit on older or slower systems.
|4K Media||Frame rate||Bandwidth||Store 1 Hour|
|H.264||30 fps||18.75 MB/sec||67.5 GB|
|ProRes Proxy||30 fps||22.75 MB/sec||82 GB|
|ProRes 422||30 fps||73.6 MB/sec||265 GB|
|BMD RAW 3:1||30 fps||~175 MB/sec||630 GB|
|R3D Redcode 4K 4:1||30 fps||215 MB/sec||774 GB|
- H.264 specs based on JVC specs
- ProRes specs from Apple ProRes White Paper
- Blackmagic specs interpolated from Blackmagic Design website
