Final Cut Pro proxy workflow

Server-side ProRes Proxy, Final Cut Library integration, FCPXML Smart Relink.

FCP proxies leave your originals on the same disk

Final Cut Pro generates ProRes Proxy inside the Library bundle, next to the original media. The Library grows to hundreds of gigabytes quickly, and you cannot easily split proxies from originals across disks without breaking FCP's expectations.

Clean split: proxies local, originals cloud

Sanbila generates ProRes Proxy on our servers and drops them into a Virtual Folder FCP imports as external media. Originals live in the cloud. FCP plays proxies at 60 fps with no lag. At export, FCPXML Smart Relink streams only timeline clips at full resolution via WebDAV.

ProRes Proxy server-side

No local CPU cost. Edit while encoding runs in the background.

External media compatible

Virtual Folders sit outside the Library bundle, Final Cut treats them as external.

FCPXML Smart Relink

Export the XML, Sanbila conforms to originals streamed from the cloud.

macOS optimised

Sanbila is a native Tauri app, not an Electron wrapper.

Frequently asked questions

How is Sanbila different from the proxy generator built into my NLE?+

Premiere Pro, DaVinci Resolve, Final Cut Pro and Avid all generate proxies locally, but they keep the original full-resolution files on the same SSD — so the disk fills up twice. Sanbila stores the originals in the cloud (Cloudflare R2) and keeps only the lightweight proxies on your machine. At export, Smart Relink streams the originals back via a local WebDAV mount, so you finish at full quality without ever downloading the source files.

Does Sanbila work offline?+

Yes for editing — once a proxy is cached on your SSD, you can cut, trim, color and arrange your timeline without an internet connection. You only need network access for the initial import (uploading originals to the cloud) and for the final export (streaming originals back via WebDAV).

How much cloud storage does the free plan include?+

The free plan includes 5 GB of cloud storage and one project, with no credit card required. Paid plans start at $49 per month for 2 TB and 50 projects, going up to 25 TB on the Enterprise plan with overage billing for teams that need more.

What upload speed do I need to use Sanbila?+

Any broadband connection works for the initial upload — Sanbila chunks files into 50 MB parts and uploads in parallel, so a typical 100 Mbps fiber line uploads 1 hour of 4K H.264 footage in about 6 minutes. After upload, day-to-day editing happens on local proxies, so your connection speed only matters again at export time when originals are streamed.

Which video formats does Sanbila support?+

Sanbila handles 22+ formats out of the box: MP4, MOV, MXF, R3D (RED RAW), BRAW (Blackmagic RAW), ARRI proxies, ProRes, DNxHR, DNxHD, H.264, H.265, plus WAV and AAC for audio. Both 4K and 8K sources are supported up to 200 GB per single file (URL imports have no size limit).
