Last updated:

March 2, 2026

‍Recast's live streaming is delivered using Mux Live Streaming software.

As explained by Mux, these streaming settings are provided to offer a very simple recommendation of where to start, but we do recommend playing with your settings to see what works best for your content.

Streaming Protocol options available:

RTMP or SRT

Video CODEC

H.264 (Main Profile)

Audio CODEC

AAC

Resolution

We support resolutions up to 1080p. We suggest streaming at one of these standard resolutions:

1920×1080 - 30fps - preferred

Bitrate: 5000 kbps
Keyframe Interval: 2 seconds

1280×720

Bitrate - 3500 kbps
Keyframe Interval - 2 seconds

854x480

Bitrate - “1500 kmps (low) 3000 kmps (high)”
Keyframe Interval - 2 seconds

‍
Frame Rate Limit

We support input frame rates up to 60fps.

Video Bitrate - Examples

As shown above, for most HD quality streams, we suggest between 3 and 6 Mbps for the video Bitrate. Here is some more detail:
‍

Bitrate Control

CBR (Constant bitrate)

Bandwidth Tuning

25% is generally a safe starting value

Set to the percentage of overhead you have available in your internet connection for bursts of retransmission. For example, if you have a 5Mbps internet connection, and you set your encoder's target bitrate to 4Mbps, a value of 25% would be appropriate, as it would allow the encoder to burst to 5Mbps for retransmission purposes.

Profile

We suggest using the main or high profile based on your output resolution and frame rate:

‍

‍

Audio Bitrate

128 kbps

Audio Channels

Stereo

Scan Type

We only support progressive scans on streams. You can stream using an interlaced feed, but we are unable to deinterlace a stream input, so artefacting will appear.

Stream Length Limit

You can stream for up to 6 hours continuously. If you need to stream for a longer duration, please contact techsupport@recastpay.com, and we can discuss your requirements.
