Live Chat Replay
YouTube Live Chat Replay is the archived chat experience that plays messages alongside a completed live stream at the times they originally appeared.
YouTube turns chat replay on by default for stream archives when live chat was available and the archive remains eligible.
How Live Chat Replay Works
When a viewer watches an archived live stream, the replayed chat advances with the video's timeline. Seeking forward or backward moves the chat to the corresponding point in the broadcast.
The replay helps viewers understand:
- Audience reactions
- Questions the creator was answering
- Moderator announcements
- Community jokes and context
- Highlighted fan-funding messages
- Live Q&A activity
Live Chat Replay vs. Comments
| Feature | Live Chat Replay | Comments |
|---|---|---|
| Timing | Synchronized with the live broadcast timeline | Posted below the archived video |
| Origin | Messages sent while the event was live | Messages posted before or after the archive is available |
| Display | Beside the video player | Below the video |
| Availability | Depends on live chat, replay settings, edits, and restrictions | Depends on the archive's comment settings |
After a live stream ends, new messages are posted as comments rather than added to the historical chat timeline.
Is Replay On by Default?
Yes. YouTube's current moderation guidance says Live Chat Replay is turned on by default for live-stream archives.
The creator can disable it for an archived stream.
How to Turn Off Live Chat Replay
- Open YouTube Studio or the creator's video-management page.
- Select Content.
- Open the Live tab.
- Select the archived stream.
- Open Customization.
- Deselect Live chat replay.
- Save the change.
Interface wording can change, but the control applies to the archived chat display rather than deleting the video archive itself.
What Happens If the Stream Is Edited?
YouTube says a live stream edited in the YouTube video editor will no longer have chat replay. This applies to every type of editor function.
Actions that can remove replay include:
- Trimming the archive
- Cutting a section
- Blurring a face or object
- Applying another supported Studio Editor change
Because Studio Editor changes may also be irreversible, preserve a local archive and consider the chat consequence before editing.
Why Does Editing Remove Replay?
YouTube does not publish a detailed technical explanation, but editing changes the relationship between the original live timeline and the archived video.
The practical rule is simple: any current YouTube Video Editor change removes the synchronized chat replay.
What Is Included in Replay?
- Ordinary public live chat messages that appeared during the broadcast
- Creator and moderator messages
- Eligible pinned-message context
- Super Chat and other supported highlighted messages
- Live Q&A sessions that YouTube preserves
The replay reflects the moderated public chat experience rather than every attempted message.
What Is Not Included?
YouTube specifically says live polls do not appear in Live Chat Replay.
Other missing content can include:
- Messages held and never approved
- Messages removed by the creator or moderators
- Messages deleted by the viewer
- Content removed for policy or spam reasons
- Private moderation interfaces
- Live reactions as a complete message history
- Poll results that existed only during the live event
Live Q&A and Replay
YouTube says completed Live Q&A sessions are available in Chat Replay. Unanswered questions are removed from the active question list when the Q&A ends.
This differs from live polls, which are explicitly live-only and omitted from replay.
Top Chat vs. Live Chat in Replay
During the live event, viewers can choose:
- Top Chat: A filtered view intended to show messages viewers are likely to value
- Live Chat: The unfiltered public message stream as messages arrive
The replay represents the archived public chat experience. It does not expose messages that moderation systems never made public.
Can a Viewer Delete an Old Chat Message?
YouTube lets viewers open their Live Chat history through YouTube History and delete messages they previously posted.
Deleting a paid Super Chat message after the stream does not create a refund.
Made-for-Kids Streams
When a live stream is set as Made for Kids, YouTube disables live chat and live chat replay.
A creator cannot restore replay for a stream that never had eligible chat because of the audience setting.
Other Reasons Replay May Be Missing
- Live chat was disabled during the stream.
- The archive is still processing.
- The creator turned replay off.
- The archive was edited in YouTube Studio.
- The stream exceeded archive limits or was not captured correctly.
- Policy or safety restrictions disabled chat.
- The video or archive was deleted or made inaccessible.
- Live chat was not supported for that event.
Stream Length and Archiving
YouTube says streams shorter than 12 hours can be automatically archived. Streams longer than 12 hours may not be captured at all.
If no playable archive exists, there is no normal synchronized video timeline for chat replay.
Replay and Public-to-Members-Only Streams
A public-to-members-only transition creates separate stream records. Each archive and its chat experience should be reviewed separately.
The members-only archive remains restricted to qualifying members, including its associated replay where available.
Replay and Subscriber-Only Chat
Messages posted during subscriber-only chat can replay with the archive. The historical messages can continue to show that the participant was eligible to chat during the event.
Creators should remind viewers that live chat can remain public after the broadcast.
Replay and Slow Mode
Slow Mode controls how often viewers can submit messages while live. Replay shows the messages at their original times.
The replay does not reproduce each participant's countdown timer or slow down playback.
Does Replay Affect Analytics?
YouTube does not provide a single metric showing how many archive viewers opened or followed Live Chat Replay.
Evaluate the archive using:
- Views
- Watch time
- Audience retention
- Comments
- Traffic sources
- Concurrent-viewer history
- Live chat message and reaction metrics where available
Benefits of Keeping Replay
- Preserves community context
- Makes Q&A answers easier to understand
- Shows the live-event atmosphere
- Recognizes participating viewers and members
- Provides social proof for future streams
- Helps viewers follow audience reactions
Reasons to Disable Replay
- The chat distracts from an evergreen archive.
- Sensitive information appeared.
- The chat became hostile or irrelevant.
- The creator wants a clean educational replay.
- Moderation quality was poor.
- The archive serves a different audience from the live event.
Disabling replay does not remove comments below the archived video.
How to Preserve Chat Before Editing
Because any Studio Editor change removes replay, creators who need a record can:
- Preserve a local stream recording.
- Capture important questions and timestamps.
- Export available live-chat data through authorized tools where permitted.
- Create a summary or FAQ before editing.
- Keep screenshots of important member or moderator messages.
Do not publish private viewer information outside its appropriate context.
Common Live-Chat-Replay Mistakes
- Assuming replay is the same as comments.
- Editing the archive without realizing replay will disappear.
- Expecting live polls to appear.
- Assuming every attempted message is preserved.
- Believing disabling replay deletes the video.
- Expecting Slow Mode timers to replay.
- Forgetting that Made-for-Kids streams cannot use replay.
- Relying on YouTube as the only stream archive.
