Modern post production is multi-site by default.

Satellite offices
WFH setups
Cloud render nodes
Vendor pipelines

accsyn synchronises assets across all of it – securely and efficiently.

You don’t adapt to the infrastructure.

The infrastructure adapts to your workflow.

API-Native by Design

Everything in the UI is scriptable.

Full Python API
Server side hooks
Publish validation hooks
Render orchestration, with custom Python script engines

Integrate accsyn directly into your pipeline, DCC tools and tracking systems like ftrack™ or Autodesk© Flow™ Production Tracking.

No automation workarounds.

No closed-box limitations.

Example API snippets:

Share a project folder:

project_share = session.create("Folder",{
    "path":"proj001",
    "name":"Proj001",
    "description":""
})

Give project access to a vendor for downloading source material and uploading produced assets:

vendor = session.find_one("User WHERE code=io@acme.co.uk")
source_acl = session.grant("User", vendor["id"], "Folder", project_share["id"], {
    "path": "src",
    "read": True,
    "write": False,
    "notify": True,
    "message": "Access source material here.",
})
work_acl = session.grant("User", vendor["id"], "Folder", project_share["id"], {
    "path": "_VENDORS/acme",
    "read": True,
    "write": True,
    "notify": True,
    "message": "Please upload your work here.",
})

Queue conform of a shot source plate on the farm – transcode, encode and publish:

conform_job = session.create("Compute",
    {
        "name": "Proj001 Conform - 260618",
        "engine": "conform",
        "tasks":{
            "sc0010_sh0010_main":{
                "parameters":{
                  "src_path":"/mnt/source/proj001/251024/A001C001_1024E4.r3d",
                  "dst_path":"/mnt/prod/proj001/ .. /proj001_sh0010_sh0010_main.%05d.exr"
                },
                "tasks":{
                    "transcode":{
                        "parameters":{
                            "in":1621, "out":1842, "profile":"4k-exr-16", "handles":8
                        }
                    },
                    "proxy-encode":{
                        "parameters":{
                            "profile":"HD-prores422hq"
                        }, 
                        "deps":["sc0010_sh0010_main/transcode"]
                    },
                    "ftrack-publish":{
                        "parameters":{
                            "task": "20365188-4529-40f6-970e-d29a3161fb39", "version":"1"
                        },
                        "deps":["sc0010_sh0010_main/proxy-encode"]
                    }
                }
            }
        },
        "metadata" = { "out_start":1001 }
    }

Battle Tested in Real Production

accsyn customer

“We see accsyn as a flexible and dependable platform. Its ability to execute custom Python scripts exactly the way we need makes it a strong fit for a modern VFX pipeline. And when we do need support, we get it quickly – which is a definite plus in production.”

Learn how accsyn drives pipeline file I/O and rendering at Filmgate VFX

Share Entire Projects, Not Just Files

Example: A drone operator uploads 4 TB of raw footage directly into your project structure.

Only changed blocks are transferred.

Interrupted transfer? It resumes automatically, and retries automatically.

ACLs (access control lists) determines which folder(s) a user can read and write, beneath your shared project folder.

Never again maintain a separate FTP account, per project with the manual labour of syncing material with your prodution storage.

TUTORIAL - FTP SERVER REPLACEMENT

Send or Receive Terabytes with One Link

Open the link in standard browser.
No technical onboarding required.
No FTP instructions.

Under the hood, the same accelerated protocol ensures:

Stable large-folder uploads
Resume support and automatic retries on failure.
Predictable performance
No hidden traffic costs or bandwidth limitations.
Request uploads by sending a single link.
Use our API to create and manage deliveries, in workflow automisations.

Publish – Automate Vendor Deliveries

Real-world example: A VFX vendor is about to deliver a final shot. Instead of “Upload and we’ll check it.” , you provide a publish portal with accsyn:

File names are validated
Frame ranges are checked
Metadata is requested (status, hours spent, version notes)
Upload location is controlled (staging or final folder)

Never again have your vendors and contractors dump their work without proper gates – a real timesaver especially if you are in different time zones.

Remove the labour of copying the work to the correct location in your project folder and ingesting the material into your production tracking tools – have accsyn automise it for you, and it can even trigger transcode of image/movie previews/proxies.

TUTORIAL - OUTSOURCING PIPELINE

Synchronise Your Physical And Cloud Locations

Install accsyn Server on a remote physical or cloud location to facilitate sync of production assets, or simply use for effective backup schemas.

Have paths volume paths mirrored during transfer, keeping directory structure with no manual folder creation.

Have your collaborators install the accsyn User Server locally, and map shares locally, enabling you to push and pull assets unattended to and from their workstation 24/7.

Use our API to automate site transfers, enabling workflows were asset synchronisation could be driven from actions within your production tools / project manager software.

Tutorial - Remote office sync

Distributed Render Farm

Run GPU and/or CPU resource intensive task on your infrastructure, with built-in support for file transport.

Synchronise render dependencies (input) and resulting data (output) between local submit locations, remote render locations, cloud render and on-prem main farm.

Supports hierarchical internal job topologies with internal dependencies, faciliates advanced nested task graphs.
Advanced pool mechanism for sharing render resources.
Highly configurable render engine execution scripts, covering almost any app be it render, transcode, ML/AI tasks or any CLI enable third party compute application.
Shares the same queue system as other accsyn job – all I/O in one place.

DOCUMENTATION

We treat I/O as infrastructure, not a utility.

File transfer is not an add-on feature

It is the backbone of:

Ingest
Collaboration
Outsourcing
Render & Transcode
Publishing
Delivery
Backup & Archiving

Post production has become distributed, automated and data-heavy.

The studios that streamline I/O

Move faster.
Deliver earlier.
Spend less time firefighting.

accsyn is built for those studios.

Security & Integrity

High-speed transfer is meaningless without control

accsyn is built with a security model designed for modern production infrastructure – not retrofitted enterprise tooling.

Unlike traditional file transfer services that expose persistent listening ports, the accsyn ASC protocol server process:

Does not listen 24/7 on incoming connections
Spawns a software-firewalled endpoint only for milliseconds during transfer establish
Restricts incoming connections to the specific remote client IP
Immediately stops listening once the secure session is established

The attack surface is dramatically reduced by design.

End-to-end encryption

All data in transit is encrypted:

AES-128 by default
AES-256 configurable for stricter environments

Your media moves encrypted across public networks – without compromise.

Web file transfers uses standard HTTPS protocol over TCP port 443.

Security Whitepaper

Modern JWT token based identity model

accsyn does not store personal passwords.

Authentication is handled via SOC2-compliant identity infrastructure using OAuth-based flows and JWT tokens.

Users can authenticate through trusted identity providers such as Google or enterprise SSO solutions.

Internally:

Token-based request validation
Role-based access control
Scoped permissions

No shared credentials.

No hidden local password databases.

Audit as a First-Class Citizen

Every action is logged:

Transfers
Publish events
API calls
Configuration changes
Farm jobs

Audit is not an afterthought, it is built into the platform.

For CTOs, this means:

Traceability
Accountability
Operational transparency
