When you start streaming, you quickly discover that software buttons come with their own language. Words like raid, VOD, and simulcast show up in your settings menu every day.

At first glance, these seem like simple technical features. A raid moves your viewers. A VOD saves your video. A simulcast broadcasts to multiple websites.

In reality, these terms carry deep cultural expectations. How an English-speaking creator uses a raid on a Western platform can look very different from how a Japanese VTuber approaches the same situation. If you broadcast to an international audience, learning both the technical definitions and the social meanings will save you from awkward misunderstandings.

Here is a plain-English guide to the essential terms that govern how streamers share viewers, store content, and broadcast across borders.

Moving Viewers: Raids, Hosts, and Relays

When your broadcast ends, you do not have to shut the door and leave your audience in the dark. You can send them somewhere else. Several terms describe how this handoff works.

Raid

A raid happens when a streamer ends their broadcast and sends their current viewers directly to another live channel. The viewers automatically switch over to the new stream, usually arriving all at once.

On Western-focused platforms, raiding is a core community-building tool. Streamers frequently raid creators they admire, personal friends, or even complete strangers in the same game category. Entering a channel with a raid message or a custom channel emote is seen as a warm greeting and an act of generosity.

However, in Asian streaming spaces—especially within Japanese VTuber culture—sending a sudden, unannounced raid to someone you do not know can cause friction. Many creators prefer to keep their chat quiet and predictable. Dropping dozens or hundreds of viewers into a smaller channel without asking can overwhelm a host who is not prepared for English comments or fast-moving chat. In these communities, raiding is usually reserved for close friends or planned collaborations.

Host

A host is an older platform feature that displays another creator's live feed on your offline channel page. Unlike a raid, your viewers stay in your room while watching the other person's video.

While some platforms have phased this feature out in favor of direct raids, the term is still used conversationally. If someone says, "Thanks for hosting me," they might mean you shared their channel link or left your channel pointing to theirs while you stepped away.

Relay

A relay is an organized group event where multiple creators stream back-to-back in an agreed schedule. Streamer A streams for one hour, then raids Streamer B. Streamer B streams for an hour, then raids Streamer C.

Relays are very popular in international creator groups, singing communities, and VTuber circles. In a relay, the raid is strictly planned ahead of time. Time management is crucial: if you run five minutes late, you delay the entire international lineup.

Saving Your Work: VODs, Archives, and Clips

Once your stream ends, your live show turns into recorded media. The words platforms use for these recordings dictate how audiences consume your past work.

VOD (Video on Demand)

A VOD is the raw recording of your entire live broadcast, saved automatically by the platform servers. On platforms that prioritize real-time interactivity, VODs are temporary. They remain visible for a few weeks before the system permanently deletes them to save server space.

Because VODs expire, many creators download them immediately to edit them later or keep a private backup on an external hard drive.

Archive

An archive refers to a permanent stream recording. You hear this word far more often on platforms like YouTube, where live broadcasts instantly convert into standard, permanent public videos.

In Japanese and East Asian creator communities, the stream archive (aakaibu) is treated with immense respect. Many viewers cannot watch live due to time zone differences or work schedules. They treat the archive like an on-demand podcast or television episode.

Because archives are permanent, creators often manage them carefully:

  • Public Archives: Visible to anyone searching the channel.
  • Unlisted Archives: Accessible only to people who have the direct link, often shared in community chat groups.
  • Members-Only Archives: Locked behind paid channel memberships, used frequently for candid chats, karaoke streams with delicate music rights, or post-stream debriefs.

Clip

A clip is a short video snippet—usually thirty to ninety seconds long—cut directly from a live stream or VOD by a viewer or moderator. Clips capture funny accidents, great gameplay moments, or funny quotes.

Clips are one of the most powerful tools for global discovery. A viewer who speaks both English and Spanish might clip a funny bilingual moment, share it on social media, and bring an entirely new demographic to your next live show.

Broadcasting Everywhere: Simulcasts and Restreams

When one platform is not enough, you encounter terms that describe sending your video to multiple places at the same time.

Simulcast (Multistream)

A simulcast—often called a multistream—is the act of broadcasting a single live video feed to two or more platforms simultaneously. For example, a creator might use broadcasting software to send their gameplay to YouTube and Twitch at the exact same minute.

Simulcasting offers clear trade-offs:

  • The Benefit: You reach viewers in regions where one platform is popular, while also reaching viewers who prefer a different website. You do not force your audience to create an account on a site they dislike.
  • The Challenge: Your audience is split. You must watch two separate chat feeds, or use specialized tools to combine both chat rooms into a single monitor screen. Acknowledging a message from Platform A can confuse viewers on Platform B who cannot see that comment.

Restreaming and Mirroring

While "restreaming" often just means simulcasting through a cloud service, it also describes a unique community practice: translation mirroring.

In international VTuber and gaming scenes, trusted community volunteers sometimes host a secondary stream—with the creator's permission—where they add live subtitles or live voice translation for viewers who do not speak the broadcaster's native tongue. If you hear someone say, "I am mirroring the stream with live English notes," this is what they mean.

Safety and Control Terms to Remember

When managing raids, archives, and simulcasts, you will run into several safety terms in your dashboard:

  • Raid Target Settings: Platform controls that let you decide who is allowed to raid you. You can set your channel to accept raids from anyone, only from friends you follow, or nobody at all.
  • Followers-Only Chat: A moderation mode that requires viewers to follow your channel for a set amount of time before typing. This is a common defense if a raid brings in rude or disruptive comments.
  • Audio Muting: What happens when automated platform scanners detect copyrighted music in your broadcast. The platform will silence sections of your VOD archive so the music is not preserved, though your live broadcast might not have been interrupted.

How to Choose Your Workflow

Now that you know the words, here is how to apply them smoothly:

  1. Before you raid a creator in another country, look at their chat. If their room is quiet, formal, or entirely in a language you do not speak, check if they have raid rules listed in their channel description. When in doubt, raid a friend instead.
  2. Decide if your channel is built on temporary VODs or permanent archives. If you want your past streams to act as a catalog for viewers in other time zones, choose a platform that keeps full recordings permanently.
  3. If you simulcast, keep your chat overlay visible on your video. When viewers on all platforms can see the chat messages appearing on your screen, they understand who you are talking to, even if the chatter is on a different website.

Streaming terms are not just technical jargon. Once you understand the community rules behind them, you can build a welcoming space for viewers anywhere in the world.
