American Society of Cinematographers – Media Hash List
ASC Media Hash List (ASC MHL)
The ASC Media Hash List (ASC MHL) defines the industry’s first open, verifiable chain-of-custody for production media, ensuring every copy of every file is complete, correct, and accountable from camera through post to archive.
Built by the ASC Motion Imaging Technology Council (MITC), ASC MHL replaces ad-hoc checksum reports with a structured XML-based manifest and linked history that record each copy and verification event. This portable, append-only audit trail travels with the media, enabling any compliant tool to reproduce or extend another’s verification without ambiguity.
Already deployed on hundreds of productions, ASC MHL has dramatically reduced time lost to data-integrity investigations. Major studios such as Netflix and HBO have adopted it as their checksum manifest standard, while leading vendors—including RED, ARRI, Pomfort, YoYotta, OffShoot, and Imagine Products—have implemented native support.
Its open-source reference implementation guarantees consistent behavior across systems and provides an accessible foundation for continued innovation. ASC MHL supports multiple hash algorithms, scales from on-set to cloud to archive, and preserves end-to-end traceability—even across hybrid workflows.
The result is a transparent, interoperable framework that transforms checksum verification from fragmented “plumbing” into a trusted production-infrastructure layer. By uniting camera manufacturers, software developers, and studios around a common integrity model, ASC MHL establishes a new global standard for trustworthy media movement—one that replaces uncertainty with proof, manual re-verification with automation, and isolated reports with an enduring, auditable history of every file’s journey.
Creamsource – Slyyd Lighting Control App
**Slyyd: Reinventing Lighting Control for Modern Production**
Slyyd is a transformative **app-first, multi-manufacturer lighting control platform** built for the realities of today’s fast-moving production environments. It reimagines decades-old workflows as **touch-focused, visual interface** for cinematographers, content creators, and virtual production teams. Launched March 2025, Slyyd transforms lighting control from command-line complexity into visual, touch-first creativity.
At its core is a **device-independent color engine** that translates creative intent into precise, consistent chromatic output across a wide range of fixture types (RGB, RGBW, RGBACL, and more). Users can select colors visually, by CIE xy coordinates, or from gel libraries, and Slyyd automatically matches those looks across mixed fixtures with accuracy and speed.
The **LookBook** replaces cue numbers with visual lighting scenes, while the **Scratchpad** enables real-time experimentation without syntax or programming overhead. Projects can be shared instantly via AirDrop, iCloud, or Dropbox, enabling seamless collaboration on set. Built entirely on Apple’s native SDKs, Slyyd offers **low-latency control**, **secure local data**, and **frictionless updates**, eliminating costly hardware refresh cycles.
In under a year, Slyyd has been adopted in **over 60 countries**, empowering crews to light faster, smarter, and more creatively. By removing friction between imagination and execution, Slyyd represents a fundamental shift in how professional lighting control is conceived, delivered, and shared — **a modern tool for the mobile, connected, creative future of production.**
Lighting control has entered the app age. Slyyd defined it.
Méduse Inc. – Safe Guns Phase Synced Flash-Gun System
Safe Guns are specialized non-firing prop guns that mimic intense muzzle flashes with embedded precision timed LED strobes, triggered by the actors wielding them.
The flashes overcome “tearing/banding” artifacts of traditional flashes hitting rolling shutters. All the guns are wirelessly connected into a controlbox that alters the timings of the flashes in milliseconds to be phase adjusted into alignment with the rolling shutters of multiple cinema cameras, mimicking timecode synced genlock.
Additional features include support for 8 channels, haptic recoil action, rapid automatic fire, digital sound effects sent to the sound department, and slaved triggering to off-camera strobe lighting (also phase synced).
First used on the HBO series THE PENGUIN, they allowed us to shoot dozens of action scenes filled with simulated muzzle flashes with no tearing artifacts, even across multiple cameras. Directors were delighted by the realistic reactions of the actors flinching from the intense lighting. DOP’s loved the added visual cues, not having to imagine what the scene would look like after VFX. AD’s were able to instantly inspect the devices for safety. Props, being responsible for their handling and distribution, integrated them easily into their workflows.
In post, editors were enabled to creatively edit with visible flashes, and VFX teams were enthralled by the robust footage, now being able to comp-in muzzle flashes on plates already filled with rich interactive light, achieving high quality results with substantial reductions in cost and time.
The system is now currently being used in other productions such as Marvel’s DAREDEVIL.
