Assistant Director, Government Administration
Our overall experience with Castr has been completely positive. We stream weekly to Facebook, YouTube, and Periscope all at the same time, and have really seen an improvement in our social media reach and especially engagement. It's a really fair price and a great service.
General Manager, Entertainment
The customer service has been great. Questions are answered in a timely manner and completely.
Assistant Pastor, Religious Institution
Overall Castr has been excellent and in the few issues I have experienced, customer service has sorted things out very quickly. I have never had my stream cut out. It offers Pull URL at no extra cost on my package which is much cheaper than other similar services.
Content Creator, Media Production
A critical part of our stream. Castr was exactly what we needed to livestream our show on multiple platforms at the same time. Simply put, we wouldn't have the audience that we currently do without Castr. It's an integral part of our daily operation.
General Manager, Broadcast Media
Best multistreaming out there! When looking for a solution to livestream to both Facebook and YouTube, we came across Castr and it solved all of our issues. We love the fact that it doesn't require you to put any of their branding in the descriptions and that the stream looks great on both sites.

-
How do I start multistreaming with Castr?
Connect Castr to your encoder with the stream key and URL on your dashboard. Add your social platforms on your dashboard either automatically or manually, then go live.
-
Can I stream to a platform that’s not on your list?
Yes.. Castr supports custom RTMP destinations, so you can stream to any platform that supports RTMP or RTMPS stream publishing.
-
Can I set up a pre-recorded stream on Castr?
Yes, you can. Using the Pre-Recorded Streams tab in your Castr dashboard, you can upload and schedule pre-recorded videos. Castr supports two streaming modes: broadcast videos on an infinite loop or with a specific date and time.
-
Can I stream 24/7?
There is no limit on how many hours you can stream via Castr. You can stream 24/7/365 without any issues.
-
My Facebook and/or YouTube stream isn’t in HD.
Castr broadcasts the exact stream you send to our service. However, Facebook and YouTube do pass streams through their transcoding standards which may degrade your multistreaming video quality.
-
My region isn’t on the list of servers. What should I do?
If you can’t find your country in the list of multistream servers, your best option is to choose the closest and most relevant to your location.
-
How can I change my region?
To switch your region, you’ll have to delete your current multistream and set up a new one. This is necessary as your stream URL and key are generated around your selected region.
