One operations hub, from venue feed to post-event delivery.
Event live streaming services are judged on repeatability: the tenth client show has to run as cleanly as the first. This is how an agency runs each event on Castr, without rebuilding the stack per show.
Contribution from the venue
-
RTMP and SRT from the control room
Send the program output from vMix, OBS, or a hardware encoder over RTMP, or over SRT with a tunable latency buffer when the venue network is unpredictable.
-
40+ ingest locations
The encoder connects to a nearby ingest point, keeping the contribution leg short wherever the venue is.
-
Backup ingest with failover
Run a redundant contribution path that takes over automatically if the primary feed drops.
Failover ingest is on Ultra and Events.
Client-facing delivery
-
Branded player per event
Embed a player styled to the client on the event site, with no platform branding in front of their audience.
-
Simultaneous destinations
The same program reaches the event page, YouTube, Facebook, LinkedIn, and custom RTMP or SRT endpoints. Plans include 6 to 30 destinations account-wide, with higher counts available on request.
-
Access control for private events
Password-protect any stream, and restrict embeds by domain or country for closed audiences.
Domain and geographic controls are on Premium and higher.
After the show
-
Automatic recording
Up to 72 hours per broadcast records without a capture step, and the recording stays available for three days to save or download.
-
Replay as a deliverable
Publish the recording to hosting for a client replay page, or hand over the file with the wrap report.
-
Ticketed events
Put a client's premium event behind pay-per-view, with payments settling in a connected Stripe account.
Concurrent live streams range from 2 to 15 by plan, with annual billing raising the counts, so an account can be sized to the agency's event calendar.

Operator fit
Designed for recurring, accountable video work.
Operational complexity matters more than company size. The strongest fit is a team with a named owner, a repeatable schedule, and a real consequence if delivery fails.

Switching to Castr
Change platforms between client events, not during one.
You do not have to cut over blind. Run Castr in parallel with your current provider while you test, and let our video team confirm the fit before anything switches.
Run in parallel
Run an internal rehearsal or a low-stakes broadcast through Castr while your current platform carries the client shows. No client sees anything until your team has signed off.
Map the workflow
Our video team reviews your event calendar, each client's destinations and branding, sub-account structure, and recording deliverables, then confirms which plan covers your concurrency.
Cut over with support
Move client events over between bookings once the rehearsal run holds up, with 24/7 human support on hand during the first client broadcasts.

Questions before you choose
Evaluate the workflow with confidence.
Feature and plan availability changes by tier. Use the full matrix for comparison, or let our team validate a complex setup.
How do you live stream an event?
Send the program feed from the venue to Castr over RTMP or SRT, then deliver it through an embedded player on the event page and to social destinations at the same time. The broadcast records automatically, so the replay is ready when the event ends. One platform covers contribution, playback, distribution, and recording.
Can we separate client projects and users?
Yes. Sub-accounts and team permissions keep each client's streams, destinations, and users separate, so an operator working one show never touches another client's setup. Additional team members are included from the Premium plan.
Can Castr support simultaneous events?
Yes. Plans include 2 to 15 concurrent live streams, annual billing raises the counts, and the sales team can size an account to a heavier event calendar.
How much should we charge clients for live streaming an event?
Most agencies price by production scope, since crew, cameras, switching, and rehearsal time drive the quote. The delivery platform is the predictable line item: Castr plans are flat monthly rates sized by concurrent streams and bandwidth, from 200 GB up to 10 TB with custom volume beyond that.
Can we run a private, invite-only event stream?
Yes. Password protection is included on every plan, and Premium and higher add domain allowlisting and geographic rules, so a client town hall or dealer conference stays with its intended audience.
How do we record and deliver the event afterward?
Every broadcast records automatically, up to 72 hours, and the recording stays available for three days. Save it to hosting for a client replay page, or download the file and deliver it with the post-event report.
Should we contribute over SRT or RTMP from the venue?
Use RTMP when the venue network is solid and the encoder chain is RTMP-first. Choose SRT when the feed crosses hotel wifi, cellular, or long-haul internet, because it recovers lost packets and can encrypt the feed. Both are included on all plans.
Can clients receive branded playback and recordings?
Yes. Combine an embedded player styled for the client, cloud recording, live-to-VOD, and hosting into the delivery package, and add pay-per-view when the client sells tickets.
Can Castr help us validate our current workflow?
Yes. Castr’s video team will walk through your current setup, from sources and destinations to audience scale, security, and monetization, and confirm the fit before you migrate.
