About: The following overview of system capabilities and technical specification relates to release v1.34.8 – July 2021.
Hint: Later updates might add, change, or remove specific aspects and capabilities regardless of whether they are listed here or not. Furthermore, your contract (MSA, individual service- or subscription order) might differ from this documentation.
Live ingest
Ingest an unlimited number of concurrent live signals from pro-cameras/encoders, mobiles, and online sources.
- SRT: SRT Caller and SRT Listener, optional encryption (AES-128, AES-192, AES-265)
- RTMP: push, pull, supporting H.264/AAC, via port 1935
- HLS: pull using M3U8 manifest; automatically using highest possible quality
- RTSP: pull; supporting RTSP 1.0 following RFC 2326
- WebRTC: via capable mobile and desktop browsers via UDP out
- IFB/Return Channel: to connected WebRTC clients via UDP
- AAC-level 3.x to 4.0: higher levels are experimental
- H.264 up to 1080p60
- MP2 audio (decoding, passthrough, in-browser live preview), supported protocols: SRT, MPEG-TS over TCP
- AC3 audio (decoding, passthrough, in-browser live preview), supported protocols: SRT, MPEG-TS over TCP
- MP3 audio (decoding, passthrough, in-browser live preview), supported protocols: SRT, MPEG-TS over TCP
- Fixed Buffer Option: enabling increased synchrony for inputs, 0.2 to 10s
- PIR video (decoding, passthrough, in-browser live preview)
- Variable Bitrate (VBR) Video and Constant Bitrate (CBR) Video
- Signal Health Monitoring: based on runtime Mbit/s
- Global ingest network: multi-geographical live source ingest for low-latency and reliable content delivery
- High-res. signal bandwidth cap: bandwidth cap per incoming connection at 25 Mbit/s (for global ingest network) / 40 Mbit/s (for dedicated inputs)
- No ingest signal limit: unlimited concurrent ingested live signals
Recording
Automatic recordings of ingested live signals.
- Recording of live signals: automatic recording of all ingested signals
- MPEG-TS container: assets as MPEG-TS (.ts) using ingest format
- Filter recordings/assets: by user, date, and format
- Access on-going recordings: recordings (growing files) are accessible for screening, transfer, and download from the first minute
- Trim assets for transfer and download: cut based on video segments; actual in- and out-points may differ up to 10s from the selection
- Asset download and transfer download: via HTTPS, transfer via FTP/SFTP
- No recording limit: unlimited concurrent recordings, new asset every 6h
Curation and control
Visual and metadata-supported content curation for easy, and fast decision-making.
- Continuous playback multi-view: with up to 48 live signals per page and unlimited pages, zoom levels for 1, 4, 12, 24, 36 and 48 signals, decoding limit for continuous playback: 12 x 720p60 per tile
- Signal routing: connect live signals to unlimited outputs
- Continuous output stream: via transcoded outputs, without reconnect on routing
- Monitoring: Monitor stream health metrics and encoding parameters for all sources and targets individually in real-time.
- Low-latency delivery: via passthrough, causes stream reconnect on routing
- Thumbnail previews: updated in ~10s intervals Geo-Location explore content on map view
- Filter live signals: by production, user, and input
Live distribution
Distribute live signals simultaneously to unlimited destinations online and to broadcast systems.
- Multi-bitrate transcoding: up to 3 qualities per transcoded output, H.264, 0.1 to 20 Mbit/s, 240p, 240i, 360p, 360i, 480p, 480i, 720p, 720i, 1080p, 1080i with 25, 29.97, 30, 50, 59.94, 60 fps, AAC (stereo), 32 to 320 kbit/s (interlacing support for top-field-first)
- Low-Latency passthrough using ingest format
- Stream Mapping: select audio or video elementary streams via PID or enumeration (order in PMT); preserve, drop or remap streams for the whole output, override for individual destinations and resource locations; transcoded outputs can carry 1 video stream and up to 8 audio streams
- Fixed Buffer Option: enabling increased synchrony between outputs, 0.2 to 10s
- Metadata: Passthrough of VANC, CC, or SCTE-35 data for passthrough outputs (not supported while transcoding or performing format conversion like SRT to RTMP)
- SRT: SRT Caller and SRT Listener, optional encryption (AES-128, AES-192, AES-265)
- Pull Locations: RTMP, MPEG-TS, HLS: RMTP via port 1935, MPEG-TS via TCP port 7777, Apple HLS via HTTPS port 443, connection cap depending on required signal bandwidth
- HLS Push: segment duration adjustable to multiple of GOP, adjustable number of segments in playlist, supporting up to 3 qualities, HLS authentication
- RTMP push: up to 10 destinations, quality selection per destination for multi-bitrate outputs, incl. RTMPS
- Static Overlay: configurable per transcoding quality, incl. image upload
- HTML5 Overlay: configurable per output via source URL
- No output limit: configure and use unlimited concurrent outputs
- Output signal delay up to 300 seconds, configurable for each target individually
Setup configuration
Easy and flexible setup configuration including runtime changes with reliable signal connections.
- Productions: configure setups based on your needs of inputs, continuous playback multi-views, and outputs
- Inputs: configure public and private invites or protocol-based sources for allocation to productions
- Outputs: configure transcoded and passthrough outputs for usage in productions
- Runtime changes: add and remove inputs and outputs without interrupting the running production; add, remove, enable, and disable destinations without interrupting active connections to other targets
- Lifespan: configure automated shutdowns for productions
Access and management
Use the system wherever you are and manage productions, users, and accounts.
- User roles: divide your team into Manager, Editor, and Contributor
- OAuth connections: for social manage accounts on Facebook, YouTube/Google, Twitch via OAuth connections without sharing credentials
- Transfer targets: configure asset transfer destinations while keeping your credentials secure and avoiding complicated workflows
- Access from anywhere: recommended: 10 Mbit/s (20 Mbit/s for 48 signals), via HTTPS, viewport of 1440 x 600 px or higher
- Browser: Reference browser and guaranteed to be fully supported: recent version of Chrome (current version or up to 3 previous versions), other browsers like Firefox and Edge (in up-to-date versions) are known to work, but not guaranteed
