Somebody sends you a path. It ends in .exr, or .dpx, or a camera RAW you have not seen since the last show. To find out whether it is the shot you want, you need the right application, the right plugin, maybe a restore from the archive, and twenty minutes you did not plan to spend. Multiply that by every result in a search and you have the real reason nobody browses the estate: looking costs too much.
Lens removes the cost of looking. It renders an in-browser media preview of about 140 formats with no restore and no specialist software, so a file can be judged where it already lives. You click a result, the frame appears, you decide. That is the whole loop, and it is the reason this post exists.
The hard cases are exactly the ones that matter in post. Lens is built to preview camera RAW, EXR, DPX in a browser, alongside broadcast video, audio, and multi-page documents. Legacy 3D is handled too: instead of asking you to fire up a DCC application, Lens renders it as a turntable you can spin in the tab. No round trip to a finishing bay, no license check, no "who still has that installed."
Two things are worth being precise about, because they are easy to overstate. First, the count. We say about 140 formats because that is what the engine covers today, not a round marketing number. Second, video weight. In our tests, Lens video previews are roughly 50x lighter than a full fetch, which is what makes scrubbing a clip over a normal connection feel like scrubbing a local file. That figure is scoped to video and measured in our own tests, and we would rather tell you that plainly than pretend it applies to everything.
The alternative to a browser preview is not slower, it is a different job. To eyeball a DPX frame the old way, someone has to know the tool, own a seat, and often stage the file back from cold storage first. Every one of those is a reason the file stays unseen, and unseen files are the ones you re-shoot, re-render, or re-license because nobody could confirm the one you had.
Lens collapses that into a link. Because the preview runs in the browser, the person who needs to look does not have to be the person with the software. A producer, an assistant editor, a coordinator, or a legal reviewer can all open the same frame from the same result, which is the difference between an archive that is technically accessible and one people actually use.
Lens is the viewing layer, and it sits on top of the search you are already running. In Asset Foundry, Gateway gives you one read-only search across cloud, on-prem and LTO tape, returning files with their checksums and metadata. You do not leave that result list to look at something. Lens turns each row into a thing you can actually see.
Run a search in Gateway across your whole estate, then click any hit. The file can be on fast disk or sitting on tape in the catalog index.
Lens renders the preview in the browser, whether it is an EXR, a DPX plate, a broadcast clip, a multi-page document, or a legacy 3D asset shown as a turntable.
Confirm it is the right take, the right version, the right plate. Keep it, reject it, or send it on, without a specialist tool in the loop.
Because the frame comes to you in the browser, nobody stages a restore just to look. The heavy fetch only happens when you have decided you actually want the file.
Looking is rarely the end of the job, and Lens is built to hand off cleanly. Once you have confirmed a plate or a take, Nexus handles atomic ingest with checksum verification on intake and routes finished deliveries to ShotGrid, so the thing you just eyeballed moves without a half-ingested sequence or a mystery version. When you need to make something rather than move it, Forge covers 13 job types and 60+ generative models behind one governed API, including ProRes and DNxHR proxies and conforms.
And when the question is not "what does this frame look like" but "what is this asset, and is it the current one," that lives in Fabric, the knowledge graph that joins ShotGrid, FileMaker and Airtable and flags current versus superseded inside the query. Lens answers the eyes-on question. The rest of the platform answers the questions around it.
Note: Lens previews without a restore and without specialist software. It does not move, transcode or write your files. Ingest and delivery are Nexus, processing is Forge, and in production deployments your content stays in your environment.
When looking is cheap, people look. Coordinators triage a drop without booking a bay. Editors confirm a version off a link instead of a phone call. Finishing checks a DPX plate before anyone stages it back from tape. The estate stops being a place you avoid because opening things is expensive, and starts being something you browse. That is the quiet win: a media preview that works on the formats that usually stop you turns "we think it is on tape somewhere" into "here it is, that is the one."
If you want to see it against your own material, the fastest path is the pilot. Point it at one production or facility, read-only, and watch how many decisions your team can make just by clicking a result and seeing the frame.
