Technical specifications¶

Rev 1.004, 08.10.26

Item	Specification
Type	Managed File Transfer (MFT) Software as a Service (SaaS) — a cloud-hosted private instance that orchestrates accelerated peer-to-peer file transfers with cloud-hosted or on-premises (BYOS) server storage, providing file deliveries, compute (render farm), and media management capabilities.
User interface(s)	Desktop application (Windows, macOS & Linux), web application (mobile-friendly), CLI (command-line interface), and Python/JavaScript APIs.
Platforms	Windows™, Unix/Linux™, and macOS™. Modern evergreen browsers (Chrome, Firefox, Edge, Opera, Safari).

Item	Specification
Hosting	VPC (isolated virtual private cloud instance), ISO 9001/14001/27001 certified hosting.
Internal communication	TLS/SSL REST & GraphQL (HTTPS on port 443).
File transfer	Software-firewalled server endpoint, 256-bit PSK authorisation, encrypted using 128-bit Advanced Encryption Standard (AES-128, default) or AES-256 (configurable). More information in the Whitepaper.
Authentication provider	Identity delegated to a configured identity service (accsyn accounts and supported external providers such as Google and Microsoft). No user passwords are stored with or distributed by accsyn to transfer peers.
Certification(s)	HBO® (Home Box Office), for use in sensitive film production.
Signup and authorisation	Self signup and workspace creation, with email verification. Login to accsyn is mandatory for all users before they can access any data.
Proxy	SOCKS (v4 & v5) support.

Item	Specification
Protocol	Proprietary accelerated file transfer protocol over TCP (default port range: 45190–45209) and HTTPS web deliveries.
Synchronisation algorithm	Compatible with UNIX rsync semantics; resumes where it left off by comparing and storing file size and modification dates. Additional one-way sync mode deletes files that do not exist on the source.
Speed	On average 2–5× faster than FTP and HTTP downloads, depending on network conditions.
Office-to-office	Supports site servers for push and pull between main headquarters and satellite offices, or employees working from home.
Web deliveries	Deliver files securely in the browser, with ZIP compression of folders and multiple files. Upload requests feature an accelerated browser uploader supporting multiple files.

Item	Specification
Admin/employee disk/storage access	Confined access to one or more volumes — directories on local or cloud storage.
User access	Through shared folders acting as collaborative work areas, or file collections. Both shares and users can be bound to a queue.
Permissions	Role-based access control (RBAC); file access defined by ACLs (Access Control Lists).
User mapped shares	Option for users to map a share locally so elevated operators can pull (upload from the client) and push (download to the client) while the remote client is online. Option to install accsyn as a User server (daemon/service) for 24/7 local sharing without the Desktop App running or a user logged in.

Item	Specification
Jobs	Hierarchical job structure with sub-tasks, each task being a file or folder on a share (server) or local disk (clients).
Queues	Queue system with individual settings such as priority, bandwidth, and hooks.
Prioritising	Transfer jobs can be re-ordered, re-queued, paused, resumed, and aborted through the user interfaces.

Item	Specification
Farm	Install accsyn as a render server, enabling execution of custom Python render app wrapper scripts.
Supported renderers	ffmpeg, Maya, Nuke, Unreal Pixel Streaming, Houdini, and more.
Wrapper render scripts	Highly configurable render scripts, available as open source.

Item	Specification
Structure	Main title folders linked to IMDb movie titles, available on accsyn Cloud Hosted Storage.
Media logging	Categorising and tagging of media — images and movies beneath main title folders, with metadata.
Proxies	Thumbnails and low-resolution image and video proxies generated by default within the platform.
Transcoding	ffmpeg cluster featuring low-resolution and VOD deliverable transcodes supporting most common formats.
Streaming	Supports web HLS streaming of video files, driven by the accsyn Delivery subsystem.

Item	Specification
Integration	Integrates with accsyn professional Media Lab Services, managed by staff with 25+ years of media industry experience.
Orders	Place a media order directly from within the accsyn Desktop application — request still images and sub-clips, VOD exports, DCP masters, and more.

Item	Specification
Experience	Delivered by staff with 25+ years of media IT experience.
Scope	Deployment and configuration (cloud, BYOS, or hybrid); integration and pipeline planning; media IT advice (storage, networking, security, operations); education and onboarding for operators, administrators, and collaborating teams.
Billing	Charged per hour.

Item	Specification
CLI	Simple command `{<subcommand> <--option> <data>}` oriented interface.
Python API	Python 3 support, available on PyPI and GitHub, with extensive documentation and tutorials.
Hooks	Configurable scripts run on server and clients upon events — init, failure, and finish.
ftrack	Full integration with the ftrack media project management tool, including an API accessor and transfer action.
Publish workflow	Configurable workflow allowing subcontractors to validate and submit work into an internal production database.
Other	Email notifications (configurable).
Tutorial	Extensive tutorials covering different integration scenarios.
