STREAMING & ENCODING

Professional Video Bitrate Calculator

Our professional video bitrate calculator determines the required Mbps for 1080p and 4K streaming across SRT, RTMP, and NDI broadcast systems.

Essential for dimensioning NDI Network capacity or determining the SRT Latency & Buffer needed for stable contribution. Explore more broadcast engineering tools for IP video and media networking.

Optimal Mbps for 1080p60 and 4K UHD Streaming

Video Bitrate 8.5 Mbps
With Audio (AAC 320k) 8.8 Mbps
SRT / RTMP Required 10.6 Mbps upload
Storage per Hour 3.8 GB/hr
Storage per Day (8hr) 30.1 GB
Required Network Bandwidth 10.6 Mbps

Real-World Use Cases

Live Streaming

Calculate the required upload speed for a CDN contribution stream from an OB van using SRT over cellular bonding or satellite uplink.

Archive Storage Planning

Estimate raw storage capacity needed for a news organisation archiving 16 hours of daily broadcast content at a specific codec and quality level.

SMPTE 2110 Network Design

Verify backbone bandwidth requirements before installing a SMPTE 2110 production network with multiple simultaneous uncompressed video streams.

Codec Migration

Compare storage savings when migrating a post-production archive from ProRes 422 to H.265 for long-term preservation at equivalent perceptual quality.

What is the Video Bitrate Calculator?

Determines the required data throughput for professional video encoding, from web-optimized H.264 streams to high-end Apple ProRes mastering and SMPTE 2110 uncompressed IP fabrics.

This utility was engineered to eliminate the guesswork from high-pressure broadcast environments. Whether you are managing multi-camera sync or complex IP networking, precision measurements ensure that the technical infrastructure stays stable throughout the duration of the event.

Real-World Use Cases

Essential for calculating uplink bandwidth for SRT or RTMP streams, estimating archive storage requirements for newsrooms, or designing the backbone of an IP-based production studio.

Understanding these variables is critical for minimizing system-wide latency and avoiding technical debt in live productions. This tool provides instant validation of your technical specifications before you even power on a single piece of hardware.

Technical Methodology

Calculates bitrate based on the relationship between resolution, frame rate, and chrominance subsampling. For compressed codecs (H264/HEVC), we utilize industry-standard bits-per-pixel-per-frame coefficients tuned for broadcast aesthetics.

Our formulas are based on established SMPTE and EBU standards. By calculating these values theoretically, engineering teams can design predictable workflows and set clear expectations for clients regarding production quality and protocol limitations.
