Creator bandwidth calculator
Video Editing Network Bandwidth Calculator: 1GbE, 2.5GbE, 10GbE or 25GbE?
Video editing bandwidth can be calculated instead of guessed. Start with the bitrate of one media stream, multiply by simultaneous streams per editor and the number of active editors, then add safety headroom for peaks and other traffic. Convert the result into megabytes per second and compare it with practical network payload and measured NAS throughput. This reveals whether the next bottleneck is Ethernet or storage.
Quick answer
The calculator turns codec bitrate and editor count into an aggregate network target
Use the result as a planning ceiling, not a guarantee. Real applications add cache, metadata, renders, ingest and protocol overhead that should be validated with production media.

Workflow decision
Choose the first network tier that clears the workload with useful margin
A link that barely equals the calculated bitrate is too tight for real studio use. Keep headroom and confirm the NAS storage can sustain the same throughput.

The planner estimates bandwidth and architecture from the information you enter. Treat it as a sizing aid, then validate the real network with a throughput test and the real NAS with the codecs, file sizes and concurrency used in production.
Creator storage checklist
Four checks before building a shared editing network
Size the media workload first
Codec bitrate, stream count, resolution and simultaneous editors define the bandwidth target before any switch or NAS model is chosen.
Keep cache strategy separate
Premiere specifically recommends local Media Cache in shared-storage workflows. Resolve and Final Cut also benefit when transient cache/proxy work is placed deliberately rather than assumed to belong on the NAS.
Measure network and storage independently
A 10GbE link can be healthy while the RAID or SSD pool is too slow. Use an Ethernet-only test and a real media copy or application benchmark before changing hardware.
Plan for aggregate users
One editor may fit inside 2.5GbE while several editors require a 10GbE or faster server-side uplink. Shared storage is an aggregate-throughput problem, not only a per-workstation port decision.
Start with Mbps from the codec, not resolution
Two 4K codecs can differ by an order of magnitude in data rate. Use camera or mezzanine codec bitrate whenever possible rather than a generic resolution assumption. For Video editing bandwidth calculator, bandwidth model checkpoint 1 places start with mbps from the codec, not resolution inside the calculated load. Measure the Video editing bandwidth calculator calculated load before altering its network tier; that bandwidth model comparison can reveal a Video editing bandwidth calculator limit hidden by the port label.
Multiply by simultaneous streams
Multicam, picture-in-picture and comparison views can read several clips at once. Count those streams because the storage and network see all of them. Section 2 of Video editing bandwidth calculator maps burst behavior to the bandwidth model. Record codec rate for Video editing bandwidth calculator, editor count, then calculated load throughput together; upgrade the network tier only after the bandwidth model evidence points there.
Multiply again by active editors
Shared storage must serve everyone simultaneously. Three editors each playing two streams create six streams of aggregate media demand before background traffic. Within the Video editing bandwidth calculator bandwidth model, treat multiply again by active editors as a production constraint. If calculated load capacity remains while the network tier saturates, favor storage; if the Video editing bandwidth calculator network tier stays idle while calculated load fills, investigate networking.
Convert bits to bytes correctly
Divide megabits per second by eight to obtain megabytes per second before adding overhead and safety margin. Keeping units consistent prevents large planning errors. Validate Video editing bandwidth calculator checkpoint 4 using representative media on the calculated load, then repeat while the network tier is busy. Watch whether bandwidth model ingest, calculated load scrubbing, rendering or network tier concurrency changes the Video editing bandwidth calculator recommendation.
Add headroom for real application behavior
A 20 to 40 percent margin accommodates protocol overhead, peak bitrate variation, audio, metadata and ordinary background activity without sizing the network at permanent saturation. For Video editing bandwidth calculator, bandwidth model checkpoint 5 places add headroom for real application behavior inside the calculated load. Measure the Video editing bandwidth calculator calculated load before altering its network tier; that bandwidth model comparison can reveal a Video editing bandwidth calculator limit hidden by the port label.
Compare with practical network payload
Raw Ethernet ceilings are 125 MB/s for 1GbE, 312.5 MB/s for 2.5GbE, 625 MB/s for 5GbE, 1,250 MB/s for 10GbE and 3,125 MB/s for 25GbE before overhead. Section 6 of Video editing bandwidth calculator maps burst behavior to the bandwidth model. Record codec rate for Video editing bandwidth calculator, editor count, then calculated load throughput together; upgrade the network tier only after the bandwidth model evidence points there.
Then compare with NAS throughput
The usable ceiling is the lower of network and storage. A calculated 700 MB/s media requirement cannot be served by a NAS array that only reads 450 MB/s even on a perfect 10GbE network. Within the Video editing bandwidth calculator bandwidth model, treat then compare with nas throughput as a production constraint. If calculated load capacity remains while the network tier saturates, favor storage; if the Video editing bandwidth calculator network tier stays idle while calculated load fills, investigate networking.
Account for write-heavy moments
Ingest and renders may happen while editors read media. A read-only calculation can be too optimistic for a busy studio where the RAID write path is slower. Validate Video editing bandwidth calculator checkpoint 8 using representative media on the calculated load, then repeat while the network tier is busy. Watch whether bandwidth model ingest, calculated load scrubbing, rendering or network tier concurrency changes the Video editing bandwidth calculator recommendation.
Proxy workflows change the input, not the math
Replace the original bitrate with proxy bitrate when editors truly cut proxies. Finishing and relinking may later require original-media bandwidth. For Video editing bandwidth calculator, bandwidth model checkpoint 9 places proxy workflows change the input, not the math inside the calculated load. Measure the Video editing bandwidth calculator calculated load before altering its network tier; that bandwidth model comparison can reveal a Video editing bandwidth calculator limit hidden by the port label.
Per-editor links and core links can differ
Each editor might fit 2.5GbE while the aggregate NAS uplink needs 10 or 25GbE. Use both individual and total results when designing switches. Section 10 of Video editing bandwidth calculator maps burst behavior to the bandwidth model. Record codec rate for Video editing bandwidth calculator, editor count, then calculated load throughput together; upgrade the network tier only after the bandwidth model evidence points there.
Use measured values after deployment
Once the NAS exists, replace estimated storage speed with sustained large-file read/write results and validate the network separately with iperf3. Within the Video editing bandwidth calculator bandwidth model, treat use measured values after deployment as a production constraint. If calculated load capacity remains while the network tier saturates, favor storage; if the Video editing bandwidth calculator network tier stays idle while calculated load fills, investigate networking.
Recalculate when the studio changes codec or headcount
A network built for two compressed 4K editors may not fit four multicam RAW editors. Keep the calculator as an architecture tool rather than a one-time purchase check. Validate Video editing bandwidth calculator checkpoint 12 using representative media on the calculated load, then repeat while the network tier is busy. Watch whether bandwidth model ingest, calculated load scrubbing, rendering or network tier concurrency changes the Video editing bandwidth calculator recommendation.
Questions creators ask
Video editing bandwidth calculator questions
How do I calculate video bandwidth?
Multiply bitrate per stream by simultaneous streams and editors, then divide by eight to convert Mbps to MB/s and add safety headroom. For Video editing bandwidth calculator, confirm this answer against its real bandwidth model before active projects move onto the network tier.
How much headroom should I add?
Thirty percent is a useful starting point for planning; adjust for ingest, renders, backups and variable-bitrate media. In Video editing bandwidth calculator, the practical ceiling may be the calculated load or network tier; measure the bandwidth model path before purchasing another link.
Does 4K always need 10GbE?
No. Codec bitrate matters more than resolution alone. For Video editing bandwidth calculator, use current application documentation whenever its bandwidth model touches permissions, mounts or shared-file behavior across the calculated load.
How many MB/s can 2.5GbE carry?
312.5 MB/s raw before overhead. A Video editing bandwidth calculator team should repeat its bandwidth model test at the intended workstation count while the network tier carries normal production traffic.
How many MB/s can 10GbE carry?
1,250 MB/s raw before overhead. For Video editing bandwidth calculator, confirm this answer against its real bandwidth model before active projects move onto the network tier.
Should I use the NAS read speed or write speed?
Use the slower relevant sustained value for the workload, and consider mixed read/write periods. In Video editing bandwidth calculator, the practical ceiling may be the calculated load or network tier; measure the bandwidth model path before purchasing another link.
How does multicam affect the result?
Each active angle adds another media stream, so multicam can multiply bandwidth quickly. For Video editing bandwidth calculator, use current application documentation whenever its bandwidth model touches permissions, mounts or shared-file behavior across the calculated load.
Do proxies change the requirement?
Yes. Use proxy bitrate for proxy playback, but remember finishing may return to originals. A Video editing bandwidth calculator team should repeat its bandwidth model test at the intended workstation count while the network tier carries normal production traffic.
Can several 2.5GbE editors use a 10GbE core?
Yes, if their aggregate demand and NAS storage throughput fit below the core capacity. For Video editing bandwidth calculator, confirm this answer against its real bandwidth model before active projects move onto the network tier.
When should I choose 25GbE?
When aggregate media demand and storage throughput can exceed the useful capacity of one 10GbE server link. In Video editing bandwidth calculator, the practical ceiling may be the calculated load or network tier; measure the bandwidth model path before purchasing another link.
