DNxHR HQX
DNxHR is the resolution-independent successor to DNxHD that Avid built for 2K, 4K and UHD workflows. The HQX flavour is 12-bit 4:2:2 at variable bitrate, sized close to ProRes 422 HQ in 1080p and scaling up to ~880 Mbps in UHD. DNxHR HQX is the preferred online and broadcast master codec in Avid Media Composer pipelines because of its 12-bit colour depth, native AMA linking and clean conform behaviour through AAF.
Examples
- •A broadcast post house masters in DNxHR HQX before the QC delivery
- •An ALEXA 35 ProRes 4444 source is transcoded to DNxHR HQX for the Avid online
- •A finishing house uses DNxHR HQX as the conform codec after a Resolve roundtrip
In Sanbila
Sanbila generates DNxHR LB proxies for the offline cut in Avid Media Composer. At conform, Smart Relink switches the timeline to the original camera files or to a DNxHR HQX online master streamed from R2 through WebDAV.
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).
