MMCR BOX
EVERY FEATURE, ONE BOX

The full engine is included everywhere — trial, self-hosted, and hosted run the same feature set.

FRAME-ACCURATE SWITCHINGZero-frame-loss transitions. TAKE is instant and the program never drops a frame.
INTELLIGENT FAILOVERDetects freeze, black, and latency, then takes the next healthy source. TR 101 290 rides along on Failover.
REAL-TIME NORMALIZATIONAutomatic framerate, resolution, and audio alignment. Mixed sources scale, crop, or letterbox to the program.
HTML5 GRAPHICS ENGINEOverlay templates, live data fields, and primed graphics ready to take.
MULTI-CHANNEL AUDIO MIXERPer-source sends, live meters, and a 16-slot commentary desk with mix-minus so talent never hears themselves delayed.
INSTANT REPLAYLive replay with a filmstrip timeline, mark in/out, and per-angle thumbnails.
SCTE-35 INSERTIONFrame-accurate ad markers and program signaling in the transport stream.
LIVE CAPTIONINGCEA-608/708 and WebVTT, burn-in, a profanity filter, and SRT export. Invite a remote captioner onto their own channel, with one burn-in on program.
REMOTE GUESTSInvite a guest from a browser or take a WHIP feed. Mix-minus return and a program tally. Return is audio today.
INDEPENDENT OUTPUTSSeveral destinations per box — each with its own codec, bitrate, graphics, SCTE, and as-run log. Program from 480p to 4K.
RECORDINGS & DVRCue a recording or file onto preview or program. Pause, seek, skip, and change speed from the console.
HEALTH ANALYSISSRT loss, RTT, bitrate, and TR 101 290 rates next to failover, so you can see why a path failed.
ALERTS & SINKSWire alerts to Slack, Teams, PagerDuty, syslog, SMTP, Redis, and SNMP.
GPU ACCELERATIONHardware encode/decode with HDR tone mapping and color correction.
ABR LADDER OUTPUTMulti-rendition ladders for OTT, with a profile per rendition.
