GoCast vs Viz CaptureCast

GoCast is a self-hosted platform for streaming and recording lectures. Organizations can run it on their own servers, keeping streaming data processing and storage under their control. It can automatically stream auditorium lectures according to schedules, while lecturers can also stream using OBS, Zoom, or other software. Lecturers manage videos through a self-service interface, and course and student enrollment information can be imported from CAMPUSonline. Live streams are recorded automatically, and video-on-demand uploads are supported. Post-processing can detect silence, create searchable transcripts, and generate thumbnails. Live chat lets listeners ask questions and upvote them; lecturers can run polls and mark or hide questions. Course access can be public, limited to enrolled or invited users, or restricted to users logged in with an LRZ ID. GoCast is open source under the MIT license and listed as free. Deployment requires worker or runner servers and shared storage. Its self-streaming guide warns that streams may be unreliable and recordings may be corrupted, and recommends keeping a local copy.

Viz CaptureCast is an on-premise, network-based appliance for capturing, composing, streaming and publishing classrooms, meeting rooms and events. It automates recording, live streaming and publishing, including scheduled workflows. Across concurrent room workflows, it can record up to six NDI or NDI|HX inputs, with recording and streaming described at up to 1080/30p. During lectures, it captures presentation slides and text for searchable video and enriched playback. A browser interface and CaptureCast Workflow Wizards configure, manage and control spaces and workflows. Vizrt lists integrations with Kaltura, Panopto and Opencast, and streaming to Vimeo and YouTube. NDI can connect directly with Microsoft Teams and Zoom. Optional CaptureCast Spaces subscriptions start with one space workflow and scale to three concurrent workflows. Vizrt describes the product for educators and corporate teams. It supports Windows, searchable transcripts, multi-camera capture, live streaming, camera tracking, LED-stage, greenscreen and live-compositing workflows. Pricing is on request; a listed USMSRP is $7,995.
