CasparCG Server vs Fourwaves: 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 Fourwaves?
Fourwaves adds custom domain support for event websites, removing the hosted-subdomain constraint for conference organizers
Fourwaves is shipping consistent weekly improvements to its conference management platform: custom domain mapping for event websites, an auth gate before registration forms, and presentation/participant visibility parity between the mobile app and event website. The platform is also tightening workflow correctness — fixing reviewer workload counts in assignment confirmation and fixing raw markup in bio rendering.

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.

Fourwaves adds custom domain support for event websites, removing the hosted-subdomain constraint for conference organizers
◆ Current state
Fourwaves is shipping consistent weekly improvements to its conference management platform: custom domain mapping for event websites, an auth gate before registration forms, and presentation/participant visibility parity between the mobile app and event website. The platform is also tightening workflow correctness — fixing reviewer workload counts in assignment confirmation and fixing raw markup in bio rendering.
◆ Where it's heading
Custom domain support moves Fourwaves toward white-label territory — event organizers can now present a fully branded web presence without the hosted subdomain being visible. The sign-in gate before forms suggests the platform is building more secure, verifiable attendee flows. Together these point to a push up-market toward professional and academic conference organizers.
◆ Prediction
Following custom domains, additional white-label features such as branded emails and registration confirmations, or improvements to the abstract submission and review workflow, are the most likely next moves.
