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?
A daily drip of conference-platform polish, with finance filtering and attendee self-service leading.
Fourwaves ships small, single-line changes to its academic conference platform on an almost daily rhythm, publishing each under a bare date. The recent window splits three ways: organization-admin finance tooling, where transactions can now be filtered by organization and by payment gateway; attendee self-service, including a sidebar listing entries already submitted and the ability to add presentations to a personal agenda from the session list; and a run of navigation and consistency fixes. No single change reshapes the product.

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
5.0MEETINGS
A daily drip of conference-platform polish, with finance filtering and attendee self-service leading.
◆ Current state
Fourwaves ships small, single-line changes to its academic conference platform on an almost daily rhythm, publishing each under a bare date. The recent window splits three ways: organization-admin finance tooling, where transactions can now be filtered by organization and by payment gateway; attendee self-service, including a sidebar listing entries already submitted and the ability to add presentations to a personal agenda from the session list; and a run of navigation and consistency fixes. No single change reshapes the product.
◆ Where it's heading
The work concentrates where operators running many events feel friction — untangling payments that arrive through shared gateways, and cutting how much attendees must re-enter across registration and submission forms. A parallel thread smooths the event-day surface, with a live-and-upcoming session panel and consistent back links, icons, and headings across detail pages. Fixes and features are interleaved continuously rather than gathered into releases, so the cadence reads as steady maintenance with incremental reach.
◆ Prediction
Expect more of the same two increments — transaction visibility for organizations running events across shared gateways, and reducing what attendees must re-enter — rather than a headline capability.
