Your post-production network is the invisible bottleneck that most teams never think about — until an editor complains that playback is stuttering, or a render that should take 20 minutes takes two hours. The storage might be fast, the workstations might be powerful, but if the network connecting them can't keep up, none of that matters.

This guide covers what creative teams need to know about networking for post-production — from the basics of bandwidth and protocols to practical recommendations for studios of every size.

Why Networking Matters More Than You Think

In a shared storage environment, every frame your editors play, every file they save, and every render they export travels over your network. A single editor working in 4K ProRes generates around 100-150 MB/s of sustained read traffic. Add three more editors, a colorist pulling full-res clips, and someone exporting a final deliverable, and your network needs to handle 500+ MB/s of simultaneous throughput without breaking a sweat.

Most office networks aren't built for this. Standard 1 Gigabit Ethernet (1GbE) maxes out at about 125 MB/s — theoretical maximum, not real-world. With protocol overhead, you're looking at 100-110 MB/s usable. That's barely enough for one editor in HD, let alone a team working in 4K.

The 10GbE Baseline

For any serious post-production environment, 10 Gigabit Ethernet (10GbE) is the minimum. At roughly 1,250 MB/s theoretical (1,000-1,100 MB/s real-world), a single 10GbE connection can support 4-6 editors working in 4K ProRes simultaneously.

What You Need for 10GbE

10GbE switch — A managed switch with enough 10GbE ports for all workstations plus your NAS. Budget $500-$2,000 depending on port count.
10GbE NICs — Each workstation needs a 10GbE network interface card. These run $100-$200 each for SFP+ or RJ45 models.
Cat6A or SFP+ cabling — Cat6A copper supports 10GbE up to 100 meters. SFP+ fiber is better for longer runs and lower latency.
NAS with 10GbE — Your storage needs to match. Most mid-range NAS units from TrueNAS, QNAP, and Synology offer 10GbE ports or expansion cards.

10GbE Cost Breakdown

For a 6-workstation post-production suite:

10GbE managed switch (8-port): $800-$1,500
10GbE NICs (6x): $600-$1,200
Cat6A cabling: $200-$500
Total network upgrade: $1,600-$3,200

That's a fraction of your NAS investment, but it's the difference between smooth 4K playback and constant buffering.

Beyond 10GbE: When You Need More

Larger facilities with 10+ editors or teams working in 8K and uncompressed formats may need to step up:

25GbE — The next practical step. 25GbE switches and NICs are becoming affordable, offering 2.5x the bandwidth of 10GbE. Ideal for facilities with 8-15 editors or mixed 4K/6K workflows.

100GbE — Enterprise-level networking for large post houses and broadcast facilities. Usually combined with SAN infrastructure. Overkill for most teams, but essential when you need 20+ simultaneous high-bandwidth streams.

Link aggregation (LACP) — Bond multiple 10GbE connections together for increased throughput to your NAS. Two bonded 10GbE links give you 20 Gbps aggregate, though individual connections still max at 10 Gbps each.

Network Architecture for Post-Production

Keep Edit Traffic Separate

The most common networking mistake in post-production is running edit traffic on the same network as email, web browsing, and general office traffic. When an editor is streaming 4K media from the NAS and someone else starts a large file download, they're competing for the same bandwidth.

The fix is straightforward: dedicated edit network. Run a separate switch (or VLAN) for storage traffic between workstations and NAS. Office traffic stays on the standard 1GbE network. Your workstations get two network connections — one for storage, one for internet.
