DNxHR LB
Avid DNxHR is the resolution-independent successor to DNxHD, supporting any frame size up to 8K. It comes in five tiers (LB, SQ, HQ, HQX, 444), where LB stands for Low Bandwidth. At 1080p, DNxHR LB targets around 36 Mbps, making it small enough for fast offline workflows but high quality enough for trusted timeline scrubbing.
Avid Media Composer treats DNxHR as a first-class native codec. Together with the .mxf container and the Avid MediaFiles/MXF/ folder structure, DNxHR LB proxies appear instantly in the Avid media browser via AMA detection, with no manual import step.
Examples
- •A 6K Blackmagic BRAW clip becoming a 1080p DNxHR LB proxy at 36 Mbps for Avid
- •An 8K RED R3D shot transcoded to DNxHR LB 720p inside the Avid MediaFiles structure
- •A 4K H.264 broadcast file becoming a DNxHR LB MXF proxy ready for an Avid newsroom workflow
In Sanbila
Sanbila offers two DNxHR LB presets (720p and 1080p) generated by FFmpeg. The optional Avid MediaFiles/MXF/ folder structure can be created automatically so AMA detects the proxies instantly.
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).
