A completed YouTube Live broadcast is managed as a Live Replay: open it in YouTube Studio, change the image in its video details, and save. An upcoming scheduled stream is edited separately through Go Live and Manage, and its edit screen may not show a thumbnail control in every version.
That distinction matters if you run a continuous video loop: the image on a replay is not the image for a future or active broadcast. First identify which state you are changing, then follow the corresponding Studio path. The label “video loop” describes your programming, not a distinct thumbnail workflow in YouTube Studio.
Identify a replay or an upcoming stream
Ask whether the broadcast has ended. If it has, YouTube lists it as a Live Replay in the Live area of Studio’s Content section. If it has not begun and has a scheduled start time, it is an upcoming stream whose details are managed from the Go Live area. These states have different editing paths.
The difference is useful for more than finding a button. A replay is an archived video with video details, including a thumbnail field. An upcoming stream is a planned broadcast with stream metadata. Changing one does not automatically change the other, and editing a replay image does not alter the thumbnail shown for a live broadcast.
For a 24/7 channel, a stream may be continuous rather than a single event with a neat start and end. In that case, check the actual item shown in Studio and its status before acting. If you are preparing a new overnight broadcast, the guide to setting up a YouTube Live stream that plays recorded videos overnight covers the broadcast workflow; this page focuses on the thumbnail attached to the relevant Studio item.
YouTube’s help uses the term “Live Replay” for a completed stream and confirms that replays appear under Content → Live. See YouTube’s live-stream help for the current terminology and navigation. Button wording can change, so treat the paths below as a way to identify the right item rather than as a promise that every screen will look identical.
Open a completed replay in Studio
Sign in to the YouTube account that owns the channel, then open YouTube Studio. In the left-hand menu, choose Content, then the Live tab. Find the completed broadcast in the list and select its title or thumbnail to open its details. Confirm that you have the replay you intend to change before editing it, especially if the channel has several similar loops or recurring devotional programmes.
The Live tab may contain multiple broadcasts with similar names. Use the title and other visible details to distinguish the correct item. Do not assume that the most recent item is necessarily the one whose image you want to replace; a recurring stream can leave several archived entries in the same list.
If you cannot find it, check that you are in the channel’s Studio account and viewing the Live tab rather than only the Videos tab. A completed live broadcast is not necessarily presented in the same place or with the same state label as an ordinary uploaded video. YouTube’s live-stream documentation describes the Live area and replays; use Studio’s current display to confirm which broadcast you have selected.
Replace and save the replay thumbnail
In the replay’s video details, locate Thumbnail. Choose the option to upload a file, select your prepared image, wait for it to appear in the thumbnail area, and select Save. YouTube’s general custom video-thumbnail instructions document the Content, video details, Thumbnail, Upload file, and Save route. The exact layout may vary slightly, but the replay is edited through its video details.
After saving, return to the replay’s details or view page and check that the selected image is attached to the intended item. YouTube says thumbnail changes may take time to appear. If the old image is still visible immediately, do not repeatedly upload different files without checking whether the new one saved; refresh Studio and allow time for the change to show across YouTube.
This update belongs to the archived replay. It does not replace an image already associated with a scheduled stream, and it does not change the image used while the broadcast is live. If you need the image for a future stream, find that scheduled item separately and inspect its edit screen, as described below.
Prepare an image that YouTube accepts
YouTube recommends a 16:9 image, ideally 3840 × 2160 pixels, with a minimum width of 640 pixels. Its help page lists JPG and PNG formats and separate file-size limits for desktop and mobile uploads: 50 MB for desktop and 2 MB for mobile. These are YouTube’s published specifications, not guarantees that every image will look good at every size. Check YouTube’s thumbnail requirements if the interface rejects your file or the current requirements matter to your workflow.
For a bhajan or ambience channel, keep the subject legible at small display sizes. A detailed temple scene can work as a full image but become indistinct in a small preview; a short programme name and one clear focal point may be easier to recognise. For a local news loop, make sure the image does not imply that an old bulletin is a new live update. The thumbnail is a label for the video, not a substitute for accurate title and stream details.
Custom thumbnails require a verified account. YouTube also says upload limits can apply daily and can vary, including by region or channel history. If Studio reports a limit or policy restriction, resolve the notice rather than trying repeated uploads. YouTube’s custom thumbnail help explains the eligibility and file guidance; its account verification information explains the verification step.
Find a scheduled stream to edit
For a stream that has not started, open YouTube Studio and choose Go Live. Open Manage, find the scheduled item, select it, and choose Edit to review its stream metadata. YouTube’s live-stream scheduling instructions describe editing scheduled stream details from this flow. The stream’s title, description, date, and other metadata belong to this scheduled item, not to a replay that does not yet exist.
Check the status and scheduled time before saving any edits. If the stream is already live, the scheduled-stream screen may not be the relevant place to change its current settings. If it has ended, use its Live Replay in Content instead. A recurring broadcast may produce a replay and a separate future scheduled item; selecting the right one is more important than following a remembered menu path.
If you are building a continuous channel from recorded material, the prerecorded video streaming guide discusses a different part of the setup. For this thumbnail task, keep the YouTube object in view: scheduled stream settings for an upcoming event, or video details for a finished replay.
Check whether the edit screen offers a thumbnail control
Once the scheduled stream’s Edit screen is open, inspect the available fields. If a Thumbnail or comparable image control appears, use it to select or upload the image and save the stream details. Then reopen or review the scheduled item to confirm the change was retained. Do not assume the control exists just because another creator’s screen or an older guide shows it.
The current official instructions confirm that stream metadata can be edited through stream settings, but they do not name a thumbnail control in every version of the scheduled-stream edit screen. The interface can differ by stream type or change over time. For that reason, the practical answer is conditional: use the thumbnail field if it is present on your item; if it is absent, do not treat a missing control as evidence that you opened the wrong page or that a hidden control must be available.
This distinction is especially important if your channel uses a webcam setup or a continuous encoder-based broadcast. YouTube’s help notes that a webcam can take a thumbnail during setup, but that is not a general promise of a custom-upload field at that exact step. A setup image and a custom thumbnail selector are not the same thing. The official guidance for scheduling a live stream is the best place to recheck current steps, while the actual screen in your account tells you which controls are available for that stream.
What to do if the control is unavailable
If the scheduled-stream edit screen has no thumbnail control, avoid spending time hunting through unrelated menus. Save other needed metadata only if you are ready to do so, then plan to update the Live Replay after the broadcast ends. In the replay’s Content → Live details, the documented Thumbnail field provides the clear route to replace the image attached to the archived video.
If the broadcast has not started and the image is essential before it does, review the current official YouTube live-stream instructions and the options shown for that stream type. You can also check whether the setup flow presents an image control before scheduling is complete. Do not rely on an old community answer as proof that every current scheduled screen has the same button; interface reports can become stale.
For a 24/7 operation, separate the image you want viewers to see on an upcoming stream from the replay thumbnail you can edit later. Keep the planned image file ready, and make the change in the relevant Studio item when its control is available. StreamNeo can remove the need to keep a local computer running for a file-based 24/7 broadcast, but thumbnail availability remains a YouTube Studio question and should be checked on the stream or replay itself.
Troubleshoot a thumbnail that will not change
Work through the simple checks before making another upload. Confirm that you selected the correct replay or scheduled stream; confirm the account is verified for custom thumbnails; check the file type, dimensions, and size against YouTube’s current guidance; and look for a notice about a daily upload limit or a policy restriction. Save the edit, then allow time for the image to appear. YouTube does not promise a fixed display delay.
If the upload itself fails, read the message in Studio rather than guessing at the cause. A file can be rejected for size or format, or the account can be temporarily unable to add thumbnails. If a daily limit notice appears, YouTube advises trying again after 24 hours. That instruction applies to the notice; it is not a general waiting period for every thumbnail change.
Once the image is accepted, check the item’s details again. If Studio shows the new thumbnail but a different YouTube surface still shows the old one, give it time and recheck later. Do not infer that the live broadcast image has changed merely because the replay’s details now show a new image. For channels that also work on stream quality, the bitrate troubleshooting guide addresses a separate operational issue; bitrate settings do not determine which thumbnail Studio displays.
For a devotional loop that uses temple imagery or recordings, thumbnail selection also does not settle the rights question for the underlying content. Review the guidance on temple recordings in a 24/7 devotional stream and check YouTube’s current official policies for your situation. A thumbnail change is a presentation edit, not a permissions decision.

FAQ
Does changing a Live Replay thumbnail change the live stream thumbnail?
No. The documented replay workflow changes the image on the completed video in its details. It does not establish that the image shown for a scheduled or active broadcast changes too; edit that stream separately if its screen offers an image control.
Where is the thumbnail option for a scheduled stream?
Open Studio, choose Go Live, then Manage, select the scheduled stream, and choose Edit. Inspect the fields on that screen: a thumbnail control may be available, but YouTube’s current instructions do not guarantee it appears in every version or for every stream.
What if Studio will not accept my image?
Check that the account is verified, then compare the file’s format, dimensions, and size with YouTube’s current requirements. Read any limit or policy notice in Studio; if it reports that a daily upload limit has been reached, YouTube advises trying again after 24 hours.
Why is the old image still visible after I saved?
YouTube says thumbnail changes may take time to appear, without specifying a fixed delay. Confirm that the new image is saved on the correct item, then allow time and check again rather than assuming a replay update has changed the live broadcast image.
