ResEditor

Calculate bandwidth for HDMI, DisplayPort, SDI, ST 2110, NDI, SRT, and RIST. The essential tool for broadcast and IP video professionals.

ResEditor is the essential bandwidth calculator and resolution analyzer for video engineers, broadcast professionals, and system integrators.

Instantly calculate whether your resolution fits a given interface, plan IP video infrastructure, and reference specifications for every major professional video standard -- all in one app.

LINK CALCULATOR Analyze resolution compatibility across display and broadcast interfaces:

• HDMI 1.4, 2.0, and 2.1
• DisplayPort 1.2 (HBR2), 1.4 (HBR3), and 2.1 (UHBR13.5)
• SD-SDI through 12G-SDI

Configure resolution, refresh rate (24-480Hz), bit depth (8/10/12-bit), chroma subsampling (4:4:4, 4:2:2, 4:2:0), and HDR mode (SDR, HDR10, Dolby Vision). See instantly whether your signal fits with color-coded bandwidth indicators and Single/Dual/Quad Link classification.

Scale resolutions from 30% to 190% and browse a grid of scalable options filtered by divisibility (x8, x16) for GPU and encoder compatibility.

IP CALCULATOR Plan professional media-over-IP infrastructure with full bandwidth breakdowns:

• ST 2110-20 (uncompressed video)
• ST 2110-22 (constant bit-rate compressed video, 2:1-20:1)
• ST 2110-30 (PCM audio via AES67)
• ST 2110-31 (AES3 transparent transport)
• ST 2110-40 (ancillary data)
• IPMX with JPEG XS (TR-08 / TR-10)
• NDI Full, NDI|HX, NDI|HX2, NDI|HX3
• SRT (with optional AES encryption)
• RIST (with FEC options)

Configure multi-stream video, audio, and ancillary data. Select network interfaces (1/10/25/100 GbE) with accurate protocol overhead accounting. Enable ST 2022-7 redundancy for dual-path bandwidth planning.

SPECIFICATIONS REFERENCE Quick-reference cards for every supported standard:

• HDMI pinouts, max resolutions, and feature support by version
• DisplayPort HBR/UHBR variants, MST, DSC, and USB-C Alt Mode
• SDI data rates, cable lengths, and embedded audio capabilities
• Complete ST 2110 suite overview with bandwidth examples
• NDI codec comparison (Full vs. HX variants) with bandwidth tables

FEATURES

• Real-time bandwidth calculations with green/red fit indicators
• Detailed video timing breakdowns (pixel clock, blanking, porches)
• Physical display size calculator (PPI-based)
• PDF export with selectable sections for system documentation
• Dark theme optimized for control rooms and on-set use
• Works completely offline -- no internet required
• No tracking, no analytics, no data collection

Whether you are verifying a 4K HDR signal over HDMI 2.1, planning a 25 GbE ST 2110 facility, optimizing NDI streams for your network, or documenting system specifications, ResEditor gives you the answer in seconds.
