FCPXML
FCPXML began as the project interchange format for Final Cut Pro X and replaced the older XMEML used by Final Cut Pro 7. DaVinci Resolve uses FCPXML version 1.9 or later to import and export timelines, which makes it the de facto exchange format between Final Cut Pro and Resolve for online and grading roundtrips. The XML is human readable and describes every clip, marker, audio level and effect on the timeline, so a parser like the one Sanbila uses can extract the list of used clips for Smart Relink without ambiguity.
Examples
- •A Final Cut Pro project locks the cut and exports an FCPXML for the colourist
- •A DaVinci Resolve project imports the FCPXML, sees every used clip and conforms to the originals
- •Sanbila Smart Relink reads the FCPXML, identifies the clips on the timeline and switches them to stream mode
In Sanbila
Sanbila Smart Relink parses FCPXML exports from both Final Cut Pro and DaVinci Resolve to figure out exactly which clips are used in the locked cut, so the WebDAV mount only exposes the originals that the timeline actually needs.
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).
