CasparCG Server vs Restream: at a glance
What is CasparCG Server?
Broadcast playout server reaches for HDR and sets a hardware floor to get there
CasparCG Server ships stable releases roughly once or twice a year, with long RC and beta runs ahead of each major. The 2.4 line delivered resolution and control-surface breadth — 8K and 4K DCI frames, custom resolutions, an interlaced mixer pipeline for field accuracy, AMCP command batching. The current 2.5.0 stable turns to colour and deployment: initial HDR support, ffmpeg 7.0, headless Linux operation, and Ubuntu deb packaging.
What is Restream?
Restream is building the production desk and the clip factory at the same time
Two workstreams dominate: live production inside Studio — scene editing while on air, webinars and Slack townhalls — and an increasingly automated clip pipeline that pulls highlights, scores them for virality and posts them without a human. The MCP server and public analytics API opened the platform to outside agents and dashboards earlier in the window.

Broadcast playout server reaches for HDR and sets a hardware floor to get there
◆ Current state
CasparCG Server ships stable releases roughly once or twice a year, with long RC and beta runs ahead of each major. The 2.4 line delivered resolution and control-surface breadth — 8K and 4K DCI frames, custom resolutions, an interlaced mixer pipeline for field accuracy, AMCP command batching. The current 2.5.0 stable turns to colour and deployment: initial HDR support, ffmpeg 7.0, headless Linux operation, and Ubuntu deb packaging.
◆ Where it's heading
The project is modernizing the parts of a playout server that determine whether it can sit in a current broadcast chain — colour pipeline, pixel format fidelity, and where it can run. That comes with an explicit hardware bargain: AVX2 is recommended now and becomes a requirement in 2.6, trading compatibility with pre-2013 CPUs for the instruction set HDR and the embedded Chrome renderer need. Alongside, Decklink and NDI integration keep absorbing steady fix work.
◆ Prediction
2.6 should complete the AVX2 transition and widen HDR beyond the current subset of producers and consumers, since the 2.5 notes describe HDR as deliberately partial.

Restream is building the production desk and the clip factory at the same time
◆ Current state
Two workstreams dominate: live production inside Studio — scene editing while on air, webinars and Slack townhalls — and an increasingly automated clip pipeline that pulls highlights, scores them for virality and posts them without a human. The MCP server and public analytics API opened the platform to outside agents and dashboards earlier in the window.
◆ Where it's heading
Restream is pushing past multistreaming into the two jobs that surround it: running the show and cutting it up afterward. Clips now originate from cloud storage links and past projects, not just live broadcasts, and autoposting means highlights can ship without anyone opening the app. Studio is absorbing production controls that used to require dedicated software.
◆ Prediction
The clip pipeline looks closest to full automation — expect more destinations after Rumble and tighter virality controls — while the MCP server's promised Studio control tools would let an assistant run the broadcast itself.
