CasparCG Server vs WebinarJam: 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 WebinarJam?
WebinarJam's feed is a funnel-marketing curriculum with no product releases in it.
Every entry in this window is educational content about running webinars: funnel stages, slide frameworks, metrics interpretation, post-webinar survey design. Several posts explain existing WebinarJam and EverWebinar functionality in detail, but none announce a change to either product. Cadence is roughly weekly and consistent.

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.
WebinarJam
5.0MEETINGS
WebinarJam's feed is a funnel-marketing curriculum with no product releases in it.
◆ Current state
Every entry in this window is educational content about running webinars: funnel stages, slide frameworks, metrics interpretation, post-webinar survey design. Several posts explain existing WebinarJam and EverWebinar functionality in detail, but none announce a change to either product. Cadence is roughly weekly and consistent.
◆ Where it's heading
The content is converging on a single argument — registrations are a vanity metric and revenue depends on what happens after the webinar ends. Posts on funnel leak points, survey questions that surface why people did not buy, and the metrics that predict revenue all steer readers toward the automated EverWebinar side of the portfolio. This reads as a positioning campaign for evergreen webinars run through the blog rather than through the product.
◆ Prediction
Expect continued EverWebinar-weighted content and more integration explainers along the lines of the Kartra post. Product direction stays unreadable here unless WebinarJam publishes release notes on a separate feed.
