Frame rate
Frame rate decides how smooth and how cinematic motion feels. Film and most cinema work at 24 fps for its familiar look, European broadcast uses 25 fps, North American broadcast uses 29.97 fps, and high frame rates like 50, 60, or 120 fps capture fast action or enable slow motion. Mixing rates in one timeline needs conversion, or motion judders.
Frame rate also has to stay consistent across a project. Cameras, audio, and the final sequence should agree, and timecode counts frames according to that rate. A clip shot at 60 fps placed on a 24 fps timeline can be slowed for smooth slow motion, but a careless mix of rates produces stutter that is hard to fix later.
Examples
- •A film is shot and finished at 24 fps for a cinematic look
- •A 120 fps clip is slowed into smooth slow motion on a 24 fps timeline
- •A European broadcast deliverable is mastered at 25 fps
In Sanbila
Sanbila preserves each clip's frame rate through proxy generation, so a proxy plays back at the same rate as its original and slots into your timeline without conversion surprises before Smart Relink swaps in the full-resolution file.
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).
