4K and higher stutter on most laptops

4K H.264 or H.265 at 100 to 150 Mbps is already too heavy for smooth real-time playback on a mid-range laptop, and 6K or 8K multiplies the load again. The timeline stutters, previews drop frames, and long-GOP H.265 is especially punishing because every frame has to be reconstructed from its neighbours before it can be shown. Keeping the masters on the laptop also fills the SSD fast: a single 8K shoot can run into terabytes.

You do not need the full-resolution master on the local disk to cut. You need a light proxy that any machine can play, and the 4K, 6K or 8K original only at the export.

1080p proxies for smooth editing at any resolution

Sanbila encodes a light 1080p H.264 proxy on the Sanbila cloud, roughly 10 to 20 Mbps, so the clip plays at full frame rate on any laptop from the past five years whether the master is 4K, 6K or 8K. Only that proxy sits on your SSD; the master stays in the cloud with an automatic backup copy and is never deleted by the cache.

You cut on the proxy, and at the export the full-resolution original comes back. In DaVinci Resolve, Final Cut Pro or Avid, Smart Relink reads the timeline and switches the clips you used to the streamed originals for a full-resolution master. In Premiere Pro the desktop panel attaches the local proxy to each 4K, 6K or 8K clip natively, so you edit light and export from the original with nothing to relink. Either way, a single 8K shoot that runs into terabytes lives in the cloud instead of on your SSD.

Plays on any laptop

A 1080p H.264 proxy at about 20 Mbps runs at full frame rate on any machine from the past five years, even against an 8K master.

4K, 6K and 8K

The same proxy workflow covers 4K, 6K and 8K from Sony, Canon, Panasonic, RED, iPhone or DJI; only the master resolution changes.

Master stays safe

The full-resolution original lives in the cloud with an automatic backup copy, never deleted by the proxy cache.

Full-resolution export

Smart Relink switches the timeline to the streamed originals, or the Premiere panel attaches proxies natively, for a full-resolution master.

Frequently asked questions

Does this work for 6K and 8K, not just 4K?+

Yes. The proxy is 1080p whatever the master resolution, so 4K, 6K and 8K all edit smoothly on the same light proxy. Only the original that streams back at export changes resolution.

Why does H.265 stutter more than H.264 at the same bitrate?+

H.265 is long-GOP, so each frame is rebuilt from its neighbours, which is heavy to scrub. A 1080p H.264 proxy sidesteps that, and the H.265 master streams back only at export.

Will the proxy cache ever delete my master?+

No. The 4K, 6K or 8K master lives in the cloud with an automatic backup copy. The cache only holds proxies on your SSD; clearing it never touches the originals in the cloud.

How do I export at full resolution after cutting on proxies?+

In Resolve, FCP or Avid, Smart Relink switches the timeline clips to the streamed originals. In Premiere the desktop panel attaches the local proxy to the 4K, 6K or 8K clip, so you export from the original with no relink.
