What’s actually slowing this PC down?

A webcast is generally a presenter-led broadcast designed mainly for people to watch; a webinar is generally an online seminar or presentation with planned attendee participation, such as Q&A or polls. The terms overlap, though, and vendors do not use them consistently. To choose well, check what attendees can actually do—not just the event’s label.
What is the difference between a webcast and a webinar?
The most useful distinction is the event’s intended experience. A webcast usually puts the presenter and broadcast flow at the centre, with most attendees watching. A webinar usually has a more structured seminar format, often with ways for attendees to ask questions, respond to polls, or otherwise participate.
This is a practical convention, not a strict taxonomy. The U.S. Food and Drug Administration groups “Webinars,” “Web Conferencing,” and “Webcast” among names for web-based presentation and meeting services, noting that capabilities and delivery methods vary. FDA guidance on accessible web conferences and webinars Webex, for example, offers a webcast view within its webinar product, and documents Q&A and polls in that view.

| Comparison | Webcast tendency | Webinar tendency |
|---|---|---|
| Attendee role | Primarily watching a presenter-led broadcast | Watching while using planned participation tools, such as Q&A or polls |
| Production | May use a producer-managed broadcast flow | May centre on a presenter-led seminar or presentation |
| Event scope | Can be a single broadcast or part of a larger event | Often a focused session; larger virtual events can include multiple sessions |
These are tendencies, not promises about a platform. Event settings determine whether people can submit questions, use polls, chat, or simply watch.

- Read Before You Buy — No Video Output: These adapters support charging and USB 2.0 data transfer, but cannot transmit video signals.

Does audience size determine whether it is a webcast or webinar?
No universal audience-size threshold defines either term. A platform may set participant limits for a particular product or plan, but that is a vendor-specific capacity rule, not a general definition. Webex’s documentation presents webcast view as a mode within its webinar offering rather than as a separate format determined by attendance. Webex feature comparison
How to choose the right format
Choose a webcast-style experience for a broadcast-first event
A webcast-style setup may suit a company announcement, keynote, product reveal, or other event where a presenter or production team delivers content and most attendees are there to watch. Check whether viewers can still submit questions or use other interaction tools if you want limited participation.

Choose a webinar-style experience for structured participation
A webinar-style setup may fit instruction, demonstrations, or presentations where attendees need defined ways to ask questions or respond. Decide in advance which interactions matter—such as moderated Q&A or polls—and confirm the platform supports them in the event mode you plan to use.
Consider an event platform for multiple sessions
If the programme spans several sessions or days, compare event-level tools as well as single-session webinar products. Kaltura distinguishes a focused, single-session webinar from a larger multi-session virtual event and describes audience-facing experiences separately from production studios.

Compare actual access and replay settings
Before choosing, verify whether the event is open, embedded, or registration-gated; whether attendees need accounts or specific software; and whether the recording, captions, and transcript will be available afterward. These options depend on the platform and its configuration, not on whether the event is called a webcast or webinar.
Accessibility and production considerations
Attendees need to receive the presentation content and, where participation is part of the event, communicate with presenters through the available tools. The FDA advises organizers to provide alternate means when someone cannot use a webinar plugin or interface to access material or participate. Plan for accessible slides and materials, captions, and an accessible recording or transcript where applicable.

StreamNeo is a separate option for keeping uploaded videos live on a YouTube channel around the clock; it is not a webcast or webinar platform for a scheduled presenter-led event with attendee interaction. You upload a recording or build a playlist, add your YouTube stream key, and go live; the cloud service loops the uploaded videos without requiring your computer to stay on.
