Frankie

Frankie is Slipmat’s streaming server. Set your encoder to these settings:

• Video resolution: 1920x1080 (at least 1280x720)
• Video framerate: 30
• Video codec: H.264
• Video bitrate: minimum 5000 Kbps, maximum 7000 Kbps
• Keyframe interval: 2 seconds
• Audio format: AAC (LC)
• Audio sample rate: 44100 (do not resample to 48k)
• Audio bitrate: 320 / CBR

RTMP server: rtmp://frankie.slipmat.io/frankie_encoder

Frankie v1 settings do not work

Frankie v2 (2025 and later) does not accept the settings of Frankie v1. If your encoder still has v1 settings, change them to the settings above.

Passthrough endpoint

For experiments

This endpoint is for experiments. For normal streams, always use the settings above, because they give your listeners the best result.

The passthrough endpoint sends your stream to listeners exactly as you send it, with no processing. It is for live coding and other screen sharing, where a smaller picture makes text impossible to read.

How it is different from the normal endpoint:

• Slipmat does not change your video, so you can send resolutions above 1080p.
• Listeners get only the quality that you send. Listeners on slow connections cannot change to a lower quality.
• You must use a 2 second keyframe interval. If you do not, Slipmat cannot cut the stream into segments correctly.

Your stream key works the same as on the normal endpoint.
