NDI vs SRT
By Jamie G
SRT Mini Server compares NDI and SRT in their latest blog post and answers a question that is often asked, “NDI or SRT?” We will highlight the key points SRT Mini Server made about NDI and SRT below.
NDI brings IP into your video production. NDI has two parts to it, special codec and transport protocol, and requires a wide network bandwidth.
“NDI is glue for build production workflow inside Studio.”

SRT is pure transport protocol that uses modern techniques only for one task: low-latency delivery of data.
“For video transmition SRT suggest standart way and all hardware and software SRT encoders use this:
1. Encodes captured video to h264 (or h265, mpeg2)
SRT Mini Server
2. Wraps this encoded data to MPEG-TS data
3. Wraps MPEG-TS data to SRT-packet and send to destination.
So SRT with h264/265 encoded data applied for one-time sending only, for example from Location to Studio.”
“SRT: provides low-latency delivery from Locations to Studio over unstable Internet connections. Also it allows use modern codec like h265 for low-bandwidth transmission
SRT Mini Server
NDI: provides low-latency workflow between nodes inside Studio without quality degradation.
.. oh , if you plan publish finalized result to YouTube, Facebook etc then don’t forget about RTMP also.
