The Complete DIT Workflow Guide for Modern Film Productions

What a DIT Actually Does

The role of the Digital Imaging Technician (DIT) sits at the intersection of technical quality control and creative support. On a film or television production, the DIT is responsible for the safe custody of digital camera media from the moment it leaves the camera until it is delivered to post-production.

That description understates the role. A DIT also manages the color pipeline on set: working with the Director of Photography to develop and implement LUT-based color management, producing daily color grades for client review, and ensuring that the creative intent established on set is preserved through delivery to the colorist.

On larger productions, a DIT may also manage the DIT cart (the hardware setup that includes high-performance storage, calibrated monitors, and transcoding workstations), coordinate with the camera department on media management, and serve as the primary technical resource on set for any issues involving digital capture.

On smaller productions, the DIT role may be combined with that of a Data Manager or handled by the camera department's senior members. Understanding where the role begins and ends on your specific production is important before you design a workflow.

The Offload Workflow Step by Step

A reliable offload workflow is the foundation of everything else. Lost or corrupted camera media cannot be recovered. Every step in the offload process exists to prevent that outcome.

Step 1: Card Cloning

When a camera card comes out of the camera, it should be offloaded to two separate physical destinations simultaneously. Never single-destination offload. Never.

The standard workflow: offload to a primary working drive and a backup drive in the same operation. Some workflows use a RAID NAS as the primary destination and a separate single drive as the backup; others use two separate single drives. What matters is that by the time the original card is formatted back into the camera, two independent copies of that media exist on separate physical devices.

Step 2: Checksum Verification

A checksum is a mathematical fingerprint of a file. MD5 and xxHash are the most common checksum algorithms used in production. After copying, the offload software recalculates the checksum of the copied files and compares them to the original. A mismatch indicates a corrupt copy. Catches the problem before the original card is formatted.

Never format a card until checksum verification has passed on both copies.

Step 3: Storage to Two Separate Drives

The backup copy must be genuinely separate from the primary. Two drives in the same physical location do not protect against theft, fire, or flood. Ideally, the backup drive goes to a different physical location at end of day: a production office, a producer's car, a locked cabinet in a different room from the primary storage.

Software Tools

Silverstack (Mac) is the most widely used professional DIT software. It handles offload with checksum verification, basic color grading and LUT management, proxy transcoding, and reporting. The interface is designed for the speed required on set.

YoYotta handles offload with checksum verification and archive management to tape (LTO). Strong choice for productions with archival requirements or for facilities that archive to tape alongside spinning disk.

Pomfort Limelight is a dedicated dailies server application that works in tandem with Silverstack. It handles proxy transcoding for editorial, dailies distribution, and LUT management. For productions distributing dailies to remote editorial teams, Limelight's web-based distribution system is valuable.

LUT Workflow

LUTs (Look Up Tables) are the primary tool for managing color intent from camera through post-production.

Camera LUTs vs Creative LUTs

Camera look LUTs (also called technical LUTs or conversion LUTs) convert log-encoded camera footage (ARRI Log C, Sony S-Log, RED Log3G10, etc.) to a display-referred color space (Rec. 709 for HD monitoring). These LUTs are applied on every monitor on set to ensure that the image everyone sees represents a proper display-ready version of the log footage.

Creative LUTs are the DP's or colorist's aesthetic vision applied on top of the technical conversion. These are "the look" of the film: the grade that establishes the tone, temperature, contrast, and color character of the image. Creative LUTs may or may not be baked into dailies for client review, depending on the production's workflow preference.

What Goes to the Colorist vs What Gets Baked for Client Review

The general principle: the colorist should always receive clean log footage, not footage with a creative LUT baked in. The LUT is provided as a reference ("this is the DP's intent"), and the colorist uses it as a starting point or reference frame for the final grade.

Dailies for client review typically include the creative LUT baked in, because clients need to see an approximation of the intended look rather than the flat log image. Clearly label all dailies with the LUT applied so everyone knows what they are looking at.

LUT files should be delivered to the colorist alongside the camera media, with clear documentation of which LUT was applied at which point in the shoot (LUTs sometimes evolve over the course of a production).

Dailies Pipeline

Dailies are the same-day processed and distributed versions of the day's footage, delivered to editorial, producers, directors, and clients for review. The dailies pipeline transforms camera media into something editorial can work with quickly.

Transcoding to proxy: Camera codecs like ARRIRAW or RED R3D are high-quality but computationally demanding. Most editorial teams work with proxy files: lower-resolution, highly compressed versions of the footage that editorial software handles easily. Common proxy formats include ProRes 422 Proxy (Mac-friendly) and H.264 or DNxHD proxies. The proxy must have identical timecode to the camera original so the editorial assistant can conform back to camera originals for final grade.

Syncing sound: On productions shooting double-system sound (a separate audio recorder rather than camera-internal audio), the DIT or an assistant must sync the camera footage to the sound files before dailies are delivered. This is done by matching the clapper (slate) visible in picture to the sharp transient on the audio track.

Sending to editorial: The dailies package includes synced proxy files, sound files or synced picture files, LUT documentation, and a daily report (sheet logging every clip, its camera roll, slate number, scene, and take). Distribution platforms like Frame.io, Limelight, or even a simple secure file transfer service can be used depending on the production's scale.

The Archive Question

When should originals be archived to long-term storage rather than kept on working drives?

The general rule: originals stay on working drives until the production's post-production is complete and deliverables have been accepted. After that, archiving to LTO tape (Linear Tape-Open) is the industry standard for long-term preservation.

LTO tape offers high capacity, long media life (30+ years under proper conditions), and a cost per gigabyte that spinning disk cannot match for archival purposes. Many post-production facilities offer LTO archiving services if a production does not have in-house tape infrastructure.

A production that wraps without archiving its originals is relying on hard drives that have a five to ten year reliable lifespan. For any production with long-term licensing or preservation value, LTO archiving is not optional.

Color Managed Delivery for the Colorist

The DIT's final responsibility in the production workflow is delivering camera media to the colorist in a way that preserves maximum quality and provides the information they need to work effectively.

Deliver originals, not proxies. The colorist grades from camera originals, not the editorial proxy. The editorial conform process re-links the proxy edit to the original media.

Include all LUT files with documentation of when and how each was used.

Provide a DIT report summarizing any exposure issues, problem cards, or cards shot under unusual conditions (high ASA, mixed lighting, physical damage to media).

Confirm deliverable specs with the colorist before the production starts, not after. The output color space, mastering format, and deliverable requirements should inform how you manage the on-set color pipeline from day one.

Common DIT Mistakes and How to Avoid Them

Single-destination offload: Covered above. Never do this.

Formatting cards before verification: The checksum exists for a reason. Never format before verification passes.

Inconsistent LUT documentation: Colorists who receive undocumented or inconsistently labeled LUTs spend significant time reverse-engineering the intended look. Document every LUT, every version, and where it was used.

Inadequate storage planning: Underestimating how much storage a production will require is a common and expensive mistake. Calculate expected data volume before production begins: daily shoot volume in GB multiplied by shooting days, multiplied by 2.5 (for dual copies plus headroom).

No daily report: A DIT who delivers media without a daily report creates work for everyone downstream. The report is documentation that protects you and the production.
