A lot of users have asked us: Can I stream to Instagram from Castr?

In 2016, Instagram released Instagram Live — a sub-feature of Instagram Stories that lets you broadcast long-duration videos in real time. Not only individual content creators but also businesses of all sizes have turned to this platform to promote their content. With around 1 billion monthly active users, Instagram will undoubtedly continue to be a one of the leading destinations for livestreaming. 

As popular as it is, there are still some limitations to Instagram Live. For now, users can only stream directly from their phones to Instagram Live. This could become inconvenient, especially when you need to stream from your computer, an encoder, or through a video streaming platform like Castr.

In this article, we’ll show you how to make these things possible. With the use of Yellow Duck, you’ll be able to stream from Castr to Instagram using RTMP connections. 

Note: Using Yellow Duck is an unofficial workaround solution for streaming to Instagram. To learn more about Instagram’s Terms of Use and Policies, please refer to their Help Center

We’ll cover:

  • Why you can’t stream from Castr to Instagram directly
  • Limitations and recommended settings for Instagram Live
  • Castr Plans that support streaming to Instagram Live
  • Stream from Castr to Instagram using Yellow Duck
  • How to set up Yellow Duck and Castr
  • How to connect OBS to Yellow Duck

Why Can’t I Directly Stream to Instagram From Castr?

It’s not possible to stream live to Instagram using Castr at the moment. The reason is that Instagram is not providing public RTMP entry points for livestreaming. 

Once Instagram makes RTMP entry points available, direct streaming will be available in Castr. However, we don’t know when, or whether, the Instagram team will make this feature available.

Instagram Live: Limitations and Specs

While Facebook Live allows you to stream up to 8 hours in a row, and up to 24 hours for YouTube Live, the maximum duration for an Instagram livestream is one hour. 

After the livestream has ended, your audience will be able to rewatch it for up to 24 hours in your Instagram Stories. One way to save your livestream permanently on your account is by sending it to IGTV. Once it’s on IGTV, it will become available on your channel until you decide to delete it.

Please also note that since Instagram livestreams are specifically designed for mobile, we recommend that you set your stream format to portrait display. Your aspect ratio for Instagram Stories video should be 4:5 or 9:16. Your resolution for portrait videos should be 600 x 750 minimum and 1080 x 1350 maximum.

Instagram Live maximum duration: 60 minutes
Recommended aspect ratio: 4:5 or 9:16
Recommended resolution: 600 x 750 or 1080 x 1350
Tip: Set your video frames to portrait modes

Which Castr Plan Should I Get to Livestream to Instagram?

Because Instagram is not included as one of Castr’s publish platforms, we will count it as a Custom RTMP destination.

You’ll need a Livestream or Multistream plan. See Castr’s full plans and pricing here.

Castr Multistream plans:

  • Broadcast ($9.99/month): stream to 1 Facebook Page/Group or Custom RTMP destination simultaneously
  • Broadcast x2 ($14.99/month): stream to 2 Facebook Pages/Groups or Custom RTMP destinations simultaneously
  • Broadcast Infinity ($39.99/month): stream to 5 Facebook Pages/Groups or Custom RTMP destinations simultaneously
  • Broadcast Business ($109.99/month): stream to 15 Facebook Pages/Groups or Custom RTMP destinations simultaneously
  • Broadcast Enterprise ($109.99/month): stream to 15+ Facebook Pages/Groups or Custom RTMP destinations simultaneously

All Castr Livestream plans: stream to 2 Facebook Pages/Groups or Custom RTMP destinations simultaneously

Important: Your stream key will expire in a few minutes. So as soon as you’re logged in to Instagram, you will have a few minutes to start your stream. It’s best to have your video streams set up and configured beforehand.
