Start with the scheduled stream itself: open YouTube Studio’s Live Control Room, choose Manage, and select the upcoming event whose thumbnail is wrong. Check its saved details, correct the thumbnail on that event, save, then confirm you are not looking at an older replay or another scheduled stream.
YouTube says that reusing stream settings copies metadata, and that thumbnail changes may take time to appear. Its guidance does not identify a single cause for every stale-thumbnail report, so work through event identity and save state before blaming an encoder or assuming a platform fault.
Open the exact upcoming event
In YouTube Studio, open Live Control Room and go to Manage. Select the upcoming gaming rerun that you intend to broadcast. Before changing anything, compare its title and scheduled date and time with your plan. A channel can have several similar events, particularly when a recurring rerun uses near-identical titles.
The aim is to establish the identity of the item, not just find a thumbnail that looks familiar. A past replay, a different upcoming event, and the event you are about to run are separate items. Editing one does not establish that another has changed. YouTube’s live streaming help describes managing scheduled streams in Live Control Room; use the selected event’s own settings as your starting point.
If the event is not obvious, pause before editing. Search the upcoming list by title and inspect the date, then open the candidate and confirm the details inside it. Do not create a second event just because the first one appears to have the old image: doing so can add another item to distinguish later without fixing the original.
Keep a simple note of which event you opened, for example “Friday rerun, 8 pm, new episode”. That small check is useful if you operate several gaming streams or hand scheduling between people. It gives you a reference while checking the saved image and reduces the chance of repeatedly changing a previous event.
Check its saved thumbnail and details
Once inside the intended event, inspect the thumbnail currently shown in its details or stream settings. Also review the title, description, scheduled date and time, and any other identifying information. The thumbnail may be old because the event still holds the previous image, but first verify what YouTube Studio says is saved rather than relying on the public watch page alone.
YouTube’s general custom thumbnail instructions describe selecting a video in Studio, choosing the thumbnail control, uploading an image, and saving. Live workflows can present controls differently according to how the stream was created, so use the control available for the selected scheduled stream rather than expecting every screen to match the general video instructions exactly.
If Studio displays the intended new image, note that fact before moving on. It means your next check is whether another surface has caught up or whether you are viewing a different item. If Studio still displays the previous image, the correction has not been verified on this event; select the thumbnail control for this event and continue with the save-and-reopen check.
It can help to compare the image visually with the source file you meant to use. Check that you chose the right episode artwork and that it is not merely a close variant with the same characters or background. A file picker can make several similar gaming images easy to confuse, and the saved item is more informative than memory of which file you intended to select.
Do not infer from a good stream preview that the thumbnail is right. The preview is useful for checking the incoming video feed and intended stream connection. Thumbnail metadata and the picture in the live feed are different things: an encoder preview does not prove which thumbnail is saved to the event.
Correct and save the event metadata
If the selected event shows the wrong image, use its thumbnail control to select the intended file, then save the event. Where the image control appears depends on the live-stream workflow. YouTube’s scheduled live stream guidance explains editing stream details when scheduling or from stream settings; follow the options shown for the event you actually selected.
Wait for the save action to complete and remain on, or return to, that same event. Then reopen its details and check what Studio displays. The important test is not whether you remember uploading the right file, but whether the saved event now shows the intended thumbnail. If it does not, repeat the edit carefully and make sure the change is saved on the selected item.
Take care not to alter unrelated details while troubleshooting. If you change the title or date as well as the thumbnail, verify those fields too before leaving the page. For recurring streams, a quick final check of the event name, time, and image is safer than relying on a sequence of edits made across several similar entries.
If Studio continues to show the old image after reopening, record the event title and the steps you took, then check the relevant YouTube Help guidance or Studio support options. Avoid repeatedly uploading variants without knowing which event is open. The supplied information does not establish a definitive cause when a thumbnail fails to display as expected, and changing unrelated stream settings is not a diagnosis.
This is a metadata correction, not a change to the video feed. If the gaming rerun has other playback problems, keep those checks separate; for example, the audio troubleshooting guide for gaming reruns addresses a different symptom. Separating the issues makes it clearer whether the event’s saved details are correct even when the stream itself needs another fix.
Confirm you are viewing that scheduled event
After saving, verify the item’s title and schedule again. Compare the Studio details with the page or surface where you noticed the stale thumbnail. A thumbnail beside a scheduled event may be confused with a replay from an earlier broadcast, a different scheduled episode, or a channel-level listing. Confirm the title and event state before editing again.
YouTube Studio’s Content > Live area distinguishes upcoming streams from live replays. Use that distinction when checking the list: an upcoming event is the one waiting to be broadcast, while a replay is the record of a broadcast that has already happened. YouTube’s overview of live streams and replays can help orient you to those separate entries.
When the encoder starts, check Live Control Room to confirm that the preview and stream status correspond to the intended event. This helps establish that your feed is connected to the event you meant to start. It does not show that the encoder controls the event’s thumbnail; keep feed verification and metadata verification as separate checks. YouTube’s encoder setup help covers the live workflow and preview checks.
For a channel with several streams, use a consistent naming pattern that includes the series or episode and a schedule detail. For instance, “Ranked matches — Episode 12” is easier to distinguish from “Ranked matches — Episode 11” than a set of events all called “Gaming live”. This is a practical organisation habit, not a platform requirement, and it helps you select the right event before changing anything.
Account for reused stream settings
If you created the new rerun by choosing Reuse settings, inspect its saved metadata closely. YouTube states that the new stream copies the previous stream’s metadata, settings, and stream key. That can be convenient when the format and broadcast setup stay the same, but it also means an old thumbnail can carry over unless you review the new event and replace it.
Treat reuse as a starting point, not confirmation that every detail is current. After creating the event, check the title, description, schedule, thumbnail, and any settings you expect to differ from the previous stream. A reused event can be correctly configured for the video feed while still showing artwork from the earlier broadcast; those are distinct parts of the setup.
A short pre-broadcast checklist is often enough: open the event in Manage, confirm the title and date, inspect the thumbnail, and verify the saved result by reopening it. If the stream is part of a repeating series, compare the artwork against the specific episode rather than only checking that it belongs to the right game. Consistent thumbnail design can make two different episodes look similar at a glance.
You do not need to avoid reuse if it saves time. The trade-off is straightforward: it reduces repeated setup, while increasing the need to review fields that should change between events. If you prefer to start fresh, you still need to verify the new event’s details; a fresh setup does not by itself prove that the correct image was selected.
Allow for thumbnail update delay
After Studio shows the correct saved image, give it time to appear on the other YouTube surfaces where you are checking. YouTube says thumbnail changes may take time to appear, but does not publish a fixed wait duration for this case. Do not treat a delay as proof that the save failed, and do not promise yourself that the image will change immediately.
Check the saved event again first. If it still shows the intended thumbnail, compare that with the watch page or channel listing after allowing time for the display to update. The two observations answer different questions: Studio helps confirm what the event holds, while a public surface shows what viewers currently see. A mismatch is worth monitoring, but it does not identify its cause by itself.
If the change is time-sensitive, make the correction well before the scheduled broadcast rather than leaving it to the last moment. This gives you room to verify the selected event and observe whether the thumbnail appears elsewhere. There is no official delay estimate in the guidance cited here, so build in a sensible buffer without assuming a particular number of minutes or hours.
Resist the urge to keep changing the image while a display is catching up. Repeated edits can make it harder to tell which version is saved and which one you are seeing. Make one deliberate correction, reopen Studio to confirm it, and then check the other surface later. If Studio’s saved details do not match your intended image, return to the event edit rather than waiting on a change that was never confirmed.
Compare the upcoming event with older replays
If the thumbnail appears correct on the upcoming event but wrong on your channel, identify exactly which item the channel surface is showing. The older replay may retain its own thumbnail, and changing the next scheduled stream does not mean the replay has been edited. In Content > Live, distinguish the upcoming item from the replay, then open the one whose image you are judging.
For an old replay, edit that replay or video item separately using the thumbnail controls available for it, then save and reopen it to confirm. Do not keep editing the next scheduled stream in the hope that it will also alter a past broadcast. YouTube documents scheduled streams and replays as distinct entries; their metadata should be checked on the item that actually displays the problem.
A useful comparison is to put the event title, scheduled date, and image side by side with the replay title and broadcast date. If the replay belongs to last week, the old thumbnail may be correct for that item even though this week’s scheduled event needs new artwork. If both entries are meant to use the same image, verify each independently rather than assuming changes propagate between them.
For future broadcasts, keep a small record of which artwork belongs to each episode. This need not become a complicated production system; a folder named by series and episode can be enough to avoid selecting last week’s file. The guide to looping recorded videos on YouTube Live covers playback continuity rather than thumbnail metadata, but the same careful separation of source material and scheduled event helps keep a rerun workflow understandable.
If you are deciding whether to run the rerun from a local computer or a remote setup, solve the thumbnail issue in Studio first. The image attached to the event is separate from where the video is played or sent from.

FAQ
Why is my scheduled gaming stream still showing the old thumbnail?
First confirm the exact upcoming event in Live Control Room > Manage and inspect its saved thumbnail. Reused settings can copy the previous stream’s metadata, and YouTube says a change may take time to appear on other surfaces.
Does changing the encoder or stream key update the thumbnail?
The thumbnail is event metadata, so check and edit it in the selected stream’s Studio settings. The encoder preview helps confirm the feed is connected to the intended event, but it does not establish which image is saved.
How long should I wait for the thumbnail to change?
YouTube says changes may take time to appear but does not give a fixed duration for this situation. Confirm the image in Studio first, then check the public surface again later rather than assuming an immediate update.
Why does the replay still have the old image after I changed the next stream?
The upcoming stream and the older replay are separate entries. Open the replay itself in Content > Live and verify or edit its thumbnail independently if that is the item showing the old image.
