An introduction to accsyn¶
What is accsyn?¶
accsyn is a SaaS (Software as a Service) platform featuring the high speed encrypted ASC file delivery protocol, designed to transport a large set of files as efficiently as possible from one physical location to another, featuring a complete I/O platform targeting film production and film distribution industries.
What can accsyn do?¶
accsyn is designed to be used in one of these two scenarios:
- Media production; Shoot/DIT, ingest, post production/vfx, rendering, collaboration, delivery and automisations.
- Media distribution and archival; Tagging and structuring, proxy generation, web streaming/previews, distribution to screen (cinemas, conferences), long term archival.
These common features are available across the platform:
- Delivery; Smooth web browser based delivery of large file sets.
- Collaboration/File Sharing; Cloud hosted or on-prem advanced ACL driven file and folder sharing, replacing FTP and similar solutions.
These features are targeting production and BYOS workspaces:
- Sync remote sites Keep your remote offices and cloud locations in sync.
- Sync remote users Push files, or pull from, remote user local mapped shares.
- Hooks Kick of automisations on certain internal events.
- Publish Build an asset validate-and-ingest workflow.
- Python API Code driven file transfers.
- Render farm Deploy a cluster of CPU/GPU machine performing heavy duty long running tasks.
These features are targeting distribution and archival:
- Media Vault; Media/master long term cloud storage with IMDB linkage, proxies, web streaming, clip extraction, Q/C.
- Lab Services; Have our partners help you refine your media assets.
Important note: The Media Vault cannot be run BYOS/on-prem as of version 3 (although this is subject to be improved in future versions). To facilitate both BYOS and Media Vault, two separate workspaces should be deployed.
Why would I need accsyn?¶
Film production, and media production in general, deals with transferring and storing filmed and processed media. What really slows down film production and distribution is slow file transfers, and limited means of organising and sharing media assets.
accsyn is designed to act as a reliable file hub throughout the entire film creation process - from shoot on set all the way to the screen - cinema or streaming.
How does it work?¶
The accsyn cloud backend both orchestrates high speed p2p transfers, compute jobs and provides media management capabilities. The accsyn app, which runs both on desktop and as a background service, acts as the high speed file transfer endpoints.

How secure is accsyn?¶
Security and integrity are paramount, all internal communications are carried over standard https protocols and the ASC (accsyn copy) accelerated p2p protocol is using standard AES industry grade encryption.
No file servers are listening 24/7, providing a minimal attack surface for hackers. Only during a brief moment during ASC file transfer init, a software firewall (only accepting connections from the remote client IP) is spawned and then torn down upon connection establishment.
For the consolidated protocol and security reference, including the architecture, transfer lifecycle, comparison with other transfer approaches, job model and performance tuning, see:
