An introduction to accsyn

accsyn is a complete file I/O platform for film and media — underpinned by the high-speed encrypted ASC (Accelerated Secure Copy) protocol.

It is offered as two product variants, each aimed at a different stage of the media life-cycle. Most organisations use one or the other; if you need both production I/O and a cloud master archive, sign up for two workspaces (BYOS + Cloud) rather than combining them in one.

Variant Stage Storage model
accsyn for media production (default) Shoot, DIT, post, VFX, collaboration, site sync, automation BYOS — your on-premises or cloud VPC storage
accsyn for media distribution Masters, archival, streaming, sales/festival delivery, lab accsyn Cloud — hosted vault storage

Both move large folders and many files securely and efficiently over ASC. Product videos for each variant are planned under the same names.

accsyn for media production

Default path for studios and post. Expose production storage you already own — on-premises or in your cloud VPC — with accelerated, secure file I/O. This is the BYOS (Bring Your Own Storage) workspace.

Watch video to get started:

Main features:

Start with BYOS and a free trial (one storage server).

Media Vault (tagging, proxies, browser streaming of masters) is not available on BYOS. For that, use a separate Cloud workspace — see below.

accsyn for media distribution

For distributors, festivals, sales agents, and archives. Host masters and deliverables in a secure cloud location, with tagging, streaming, delivery, collaboration, and lab handoff. This is an accsyn Cloud workspace with Media Vault.

Typical capabilities:

  • Tag and organise masters in the Media Vault (IMDb linkage, proxies, QC-oriented workflows)
  • Stream and deliver to cinemas, buyers, and partners (Stream, Delivery)
  • Collaborate on sales and festival packages (Collaboration)
  • Transcode deliverables, validate media including DCP check.
  • Central monitoring with Job & Wueue management
  • Professional Lab services for mastering, VOD export, QC, and more

Start with a Cloud trial (500 GB) and the Media Vault guides.

Production + distribution together?

There is no benefit today to combining BYOS production storage and Media Vault in a single workspace. If you need both:

  1. A BYOS workspace for production I/O on your own storage
  2. A separate Cloud workspace for the master archive, streaming, and lab

See also the note under Media Vault.

Why accsyn?

Slow transfers and fragmented tools still dominate media pipelines. Accsyn is the file hub from set to screen — cinema or streaming — with ASC for accelerated peer-to-peer transfers, central orchestration, and audit.

Security highlights: HTTPS for control-plane traffic; AES-encrypted ASC for data; on-demand listeners (no ASC port open 24/7). Full detail: Whitepaper.

How does it work?

The accsyn cloud backend orchestrates high-speed P2P transfers, compute jobs, and (on Cloud) media management. The Desktop App (and background daemon / User server / BYOS storage server) acts as the transfer endpoint on each machine.

Licensing and pricing

An accsyn licence includes unlimited traffic, bandwidth, and standard users (delivery recipients and file-sharing users). Operator seats and storage (Cloud) or servers (BYOS) are licensed separately.

Essentials / Lite are budget variants: Essentials is 500 GB Cloud with one operator and no API; Lite is one BYOS storage server with two operators and no API.

Lab and professional services

Media Lab — Partner lab work (mastering, VOD export, QC, grading, and more), charged per order item, hours, and deliverable. Place orders from the Desktop App on Cloud (distribution) workspaces.

Professional services — With 25+ years of media IT experience, billed hourly for:

  • Deploying and configuring accsyn (BYOS production, Cloud distribution, or hybrid with two workspaces)
  • Integration and pipeline design (deliveries, sharing, sites, hooks, compute)
  • Media IT advice (storage, networking, security, operations)
  • Education and onboarding
