Service: CSDMBase (PIX System / Autodesk Flow Capture)
Protocol: TCP/UDP
Port Range: Registered (1024-49151)
Status: IANA registered1
What This Port Does
Port 1467 is registered with IANA as "csdmbase" and is primarily used by PIX System, now known as Autodesk Flow Capture.2 This software provides secure access to film and television production content - dailies, rough cuts, VFX shots, sound mixes - allowing film professionals to review footage on their mobile devices, laptops, or televisions from offices, homes, or while traveling.3
When a cinematographer wants to see yesterday's takes, when a director needs to review a scene from another continent, when a producer checks on multiple productions simultaneously - that content likely flows through port 1467.
The PIX System Story
PIX System was created in 2003 by Eric Dachs after working as an assistant to sound designer Ren Klyce on the 2002 film Panic Room. Dachs saw how difficult it was to securely share production content and built a system to solve that problem.4
The platform has been used in the production of more than 5,000 films including A Star Is Born, Black Panther, First Man, Green Book, Roma, and Spider-Man: Into the Spider-Verse. In 2019, PIX won a Technical Achievement Award from the Academy of Motion Picture Arts and Sciences for its digital rights management (DRM) system - recognition that protecting content is as important as delivering it.5
Autodesk acquired PIX (through its acquisition of Moxion) and now offers it as Flow Capture, continuing its role in modern film production workflows.6
How It Works
CSDMBase on port 1467 handles the communication between PIX clients and servers. The system uses digital rights management to ensure that production content - often worth millions of dollars and subject to strict confidentiality agreements - can be shared securely without leaking to the public.
The protocol needs to handle large video files efficiently while maintaining security. A single day's worth of 4K footage from a major production can be hundreds of gigabytes. Port 1467 facilitates the transfer and streaming of this content to authorized viewers worldwide.
Security Considerations
Port 1467 carries some of the most valuable digital assets in entertainment - unreleased films, unfinished VFX shots, alternate takes that reveal creative decisions. The content flowing through this port is protected by:
- Digital Rights Management (DRM) - prevents unauthorized copying or distribution
- Encryption - ensures content cannot be intercepted in transit
- Access controls - limits who can view specific content
- Watermarking - tracks who viewed what and when
If you see unexpected traffic on port 1467, verify it's from legitimate PIX/Flow Capture software. Unauthorized services using this port could indicate an attempt to intercept production content.
Checking What's Listening

If PIX or Flow Capture is running, you'll see the associated process. If something else is using port 1467, investigate whether it's legitimate software that chose this port or a potential security concern.
Why This Port Matters
Port 1467 represents the invisible infrastructure of modern filmmaking. Before secure digital delivery systems like PIX, production footage was physically transported on hard drives or transmitted over expensive dedicated networks. The ability to securely stream dailies anywhere changed how films are made.
Directors can now work remotely with editors in different cities. Producers can monitor multiple productions from a single location. Visual effects teams can review shots without waiting for physical media to arrive. The port itself is just a number, but what flows through it is the raw material of cinema - the unfinished moments that will eventually become the films we see in theaters.
Related Ports
- Port 443 (HTTPS) - PIX likely uses HTTPS for web interface access and additional secure communications
- Port 80 (HTTP) - May be used for initial connections before upgrading to secure protocols
- Custom ephemeral ports - Large file transfers often use dynamically assigned ports for data channels
