What Is a Digital Intermediate?
A digital intermediate, often shortened to DI, is a digital picture-finishing process in which images are prepared, assembled and graded for final output. The term comes from workflows that scan motion-picture film into digital files, perform finishing work digitally and may record the result back onto film.
In current production language, “the DI” can also mean the final picture-finishing and grading stage of a digitally photographed project. The precise service varies between facilities. If a quote includes DI, ask what it covers: conform, grading, visual-effects updates, cleanup, titles, mastering and quality control may be priced or scheduled separately.
Why It Is Called an Intermediate
In a photochemical workflow, intermediate film elements help carry an image from the original negative to release materials. A digital intermediate moves substantial work into a digital stage between capture and final exhibition. Film can therefore be photographed on a camera negative, scanned, finished digitally and recorded to a new film element for printing.
A film-out is the recording of digital images onto film. It can follow a DI, but it is not mandatory. Digital cinema and other file-based deliveries can be created without making a physical film print. Kodak still manufactures intermediate stocks designed for recording digital images, showing why digital and photochemical stages are not mutually exclusive.

What Happens During Finishing?
The finishing team first needs the correct source images and a reliable record of the approved edit. Conforming reconnects the cut to appropriate finishing media and checks that the result matches the editorial reference. Shot order is only part of this check: retimes, reframing, transitions and version changes can also matter.
Color grading balances shots and develops the intended visual character. Finished visual effects replace temporary versions, while other agreed finishing work prepares the image for output. These activities can overlap. A late VFX replacement needs checking in context because its appearance may differ from the temporary image used during the grade.
Color management keeps track of what the image data means and how it should be displayed. A creative look and an output transform have different jobs. A look shapes the image; an output transform prepares it for a target viewing system. Confusing them can result in a look being applied twice or a preview appearing very different from the final output.
Preparing a Small Project for DI
For a short film, speak to the finishing facility before the final editorial export. Agree the interchange format, reference movie, source-media access, frame rate, resolution and expected deliverables. Include a record of unusual effects and speed changes. Do a brief round-trip test while there is still time to correct transfer problems.
For example, imagine an editor cuts camera proxies and uses a temporary sky replacement. At turnover, the finishing team must recover the correct original shots, reproduce a slow-motion section and replace the temporary sky with its approved final version. Exporting the proxy timeline as one compressed movie would remove much of that flexibility.
Bring clear creative references and distinguish a reference look from an approved technical setting. If the project needs both a cinema version and a home-viewing version, discuss the additional review and adaptation work. One output file should not be assumed suitable for every display or delivery specification.
DI Is Not Just Another Name for Editing
The picture edit decides the sequence, timing and structure of the film. DI generally finishes the selected images. Color grading is a major part of that process, but a grading-only service may not include conforming, title work or final quality control. Likewise, sound mixing is a separate discipline even when one post house handles both.
Review the final exports, not only the grading timeline. Check image framing, titles, shot versions and playback against the approved reference. Preserve the source media, finishing project and agreed masters so later changes do not depend on a single delivery encode.
Frequently Asked Questions
Does DI always mean 4K? No. Resolution is a project and delivery decision. Ask what resolution is being scanned, processed and delivered rather than inferring it from the term.
Is an answer print a DI? No. An answer print is a physical trial print evaluated in a film-printing workflow. A DI may precede it, but the terms identify different things.
