To add a title and thumbnail to a Castr YouTube live stream, first identify whether your YouTube destination is connected through Castr’s API flow or with a manual stream key. Title and description controls depend on that choice; thumbnail setup belongs in YouTube Studio’s scheduling or stream-management workflow, not Castr’s destination form.
A Castr project name is not necessarily the public YouTube title. Treat the Castr project, YouTube event metadata and thumbnail as separate details, then check the scheduled stream in YouTube before you go live.
Connect YouTube to Castr
In Castr, open an existing live-stream project or create one, then add YouTube as a destination. Castr’s YouTube connection guide describes two routes: authorise a YouTube Events connection, or enter YouTube’s streaming server and stream key manually. The labels and exact screen sequence can change, so follow the options currently shown in your account.
Before connecting, make sure you are signed into the YouTube channel that should host the stream. This is a simple but consequential check: authorising the wrong channel can leave you configuring an event that is not visible where your viewers expect it. If you manage several channels, confirm the channel name and avatar in the authorisation flow rather than relying on a browser tab’s previous sign-in.
Castr’s own project or stream name helps you recognise the item in its dashboard. It does not, by itself, prove that YouTube will display that wording as the event title. That distinction matters if you name a project “Evening Bhajans” for your team but want the scheduled public title to include a date or programme detail.
Plan these three pieces separately: the Castr project name for your own organisation, the YouTube title and description for viewers, and the thumbnail shown with the scheduled or live stream. For an always-on music or ambience channel, a clear repeatable title convention can help you recognise the right event without changing the artwork every time. YouTube metadata should still describe what that specific stream contains.
Choose an API or manual connection
The API-linked route and manual stream-key route are not simply two labels for the same metadata workflow. With the API path, Castr connects to a YouTube event and its setup flow provides fields for the event title and description. With manual setup, Castr receives the server address and key to send the video feed; Castr’s guide directs you to YouTube’s dashboard for description edits.
| Connection route | What you provide in Castr | Where the documented metadata controls are | Best fit |
|---|---|---|---|
| YouTube Events/API | Authorise the channel, choose an event, and enter the event details shown in the flow | Castr provides title and description fields; YouTube Studio remains the place to manage the thumbnail and verify details | You want Castr’s documented event-level title and description setup |
| Manual stream key | YouTube streaming server and stream key | Castr says to edit the description in YouTube’s dashboard; use YouTube’s scheduling or stream settings for title and thumbnail | You already manage the YouTube event in Studio or need a manual feed connection |
The API route is useful when you want to choose the event and enter its public-facing title and description as part of the Castr setup. It also makes the relationship between a Castr destination and a YouTube event more explicit. It does not mean every YouTube setting is editable there: the reviewed Castr material does not show a thumbnail control in the destination form.
Manual setup can suit an encoder workflow where YouTube Studio is already the place you schedule and maintain the event. The trade-off is that video routing in Castr and public metadata management in YouTube are distinct tasks. Keep a note of the event you scheduled so that the feed is sent to the intended stream key.
YouTube describes a stream key as the credential and address associated with an encoder connection; its live stream settings help uses the comparison that stream keys are like a stream’s password and address. Handle the key accordingly. Do not paste it into a public note, and if you suspect it has been exposed, review YouTube’s current controls for replacing or resetting it.
Set title and description in the API flow
When you use the YouTube Events/API connection, choose the channel or event presented in Castr, then enter the title and description in the fields provided before creating the platform. Check spelling, punctuation and the intended audience-facing wording. A title that is clear in a dashboard is not always clear to someone seeing it in YouTube search, recommendations or a notification.
For a devotional channel, for example, you might identify the kind of programme and the language or tradition in the title, then use the description to explain the schedule or contents. For a study stream, the title could state that it is a study-music live stream, while the description clarifies whether the video is continuous or a scheduled session. Keep these details truthful; do not imply that a stream is live performance if it is a prerecorded loop.
After creating the platform, verify the event in YouTube Studio rather than assuming the entry in Castr is the final word. Open the correct scheduled stream and inspect its visible title and description. YouTube Help explains that metadata can be edited during creation or scheduling, and later through the stream settings’ edit controls. The YouTube interface may show slightly different wording or placement over time.
Castr also documents a social metadata API for changing title and description on destinations linked through its dashboard using the YouTube API. Its Manage Social Media Meta documentation describes those metadata fields. The documented endpoint does not specify thumbnail updates, so do not treat it as a way to upload or change the image.
If you change the title after configuring Castr, check that the change is attached to the intended YouTube event. The key practical distinction is whether you edited a Castr project label, a YouTube event’s metadata, or a different scheduled broadcast. A short verification pass in Studio is quicker than finding out after viewers have been sent the wrong event link.
Edit metadata for a manual connection
With a manual stream-key connection, Castr’s role in this step is to send the broadcast to the server and key associated with the YouTube stream. Castr’s connection guidance points manual users to YouTube’s dashboard to edit the description. Manage the public-facing event in YouTube Studio, where you can also inspect the title and other stream details.
A useful sequence is to schedule or open the event in Studio first, enter its title and description there, and then copy the matching stream server and key into Castr. If your workflow starts in Castr, return to Studio before going live and confirm that the intended event carries the right title and description. Either order can work; what matters is that the destination and metadata refer to the same event.
Do not assume changing Castr’s internal project name will update YouTube. Likewise, changing the YouTube title does not rename the project in Castr. If several streams have similar names, use a consistent internal naming pattern and add enough distinction in YouTube’s public title for viewers to identify the correct one.
Manual routing is also worth documenting for anyone else who may operate the channel. Record which YouTube event corresponds to the Castr destination without recording the stream key in an unsecured shared document. If another operator updates the description or title in Studio, ask them to leave the project label alone unless they are deliberately changing Castr’s internal organisation as well.
If your wider setup depends on a local computer running an encoder, compare the operational responsibilities with a PC-based always-on music stream setup. The metadata workflow described here is separate from how the video is produced or transmitted. A title or thumbnail edit will not fix a feed that stops when the encoder computer sleeps or loses its connection.
Add a thumbnail in YouTube’s scheduling workflow
Use YouTube Studio to add or replace the thumbnail. Google’s Full Live Production guide places custom thumbnail setup in YouTube’s scheduled-stream workflow. The source material reviewed for this guide does not show a thumbnail upload control in Castr’s YouTube destination form, and Castr’s documented metadata endpoint covers title and description rather than thumbnail changes.
In practice, open the stream in YouTube Studio’s scheduling or live-management flow and look for the thumbnail or image control in the event settings. Upload or select the intended image there, save the change, and revisit the event to make sure it is associated with the right stream. YouTube’s interface can change, so follow the current labels in your account rather than relying on a fixed button position from an older walkthrough.
Do this while scheduling when possible, especially if viewers will see the event before it starts. A thumbnail is a separate asset from the video feed: Castr sends the broadcast, while YouTube displays the artwork attached to the event. If a thumbnail is missing or incorrect, first check the event in Studio rather than changing Castr’s destination settings.
Choose artwork that remains legible when displayed small. A simple image with a short identifying phrase is usually easier to recognise than a dense collage of tiny text. For a recurring devotional stream, the channel identity and programme name can be consistent, while a date or special-event label can distinguish a one-off broadcast. Keep the image and title aligned so viewers are not led to expect different content.
Avoid making the thumbnail carry information that belongs in the description, such as a long schedule or multiple announcements. The description gives you room for context; the thumbnail should identify the stream at a glance. Once it is saved, preview the event as a viewer would see it and verify that the image is neither cropped in a confusing way nor attached to a neighbouring scheduled stream.
Check the live stream details
Before starting the broadcast, check the YouTube event and the Castr destination as two parts of one setup. In Studio, confirm the channel, event title, description and thumbnail. In Castr, confirm the intended YouTube destination and, for a manual setup, the server/key association. These checks address different failure points: the event can have correct artwork but receive the wrong feed, or the feed can be correct while the event shows stale metadata.
Where possible, use the event link from Studio to verify the public-facing page. Confirm that the title is readable, the description is the intended one, and the thumbnail shown belongs to this scheduled stream. If you have changed any of these details close to start time, refresh the event page and check that the saved version is visible before sharing it widely.
A small checklist can make handovers more dependable:
- Is this the correct YouTube channel and scheduled event?
- Does the public title describe the actual programme?
- Is the description current and free of old dates or links?
- Is the chosen thumbnail attached to this event in YouTube Studio?
- Does Castr point to the same event or manual stream key that you checked?
For long-running playlists, operational problems are distinct from metadata problems. If a stream reconnects but audio disappears, the investigation is about playback and timestamps, not the YouTube title; see this guide to audio loss after a playlist stream reconnects. Similarly, a correct thumbnail cannot prevent YouTube ending a stream after an encoder disconnect; that is a feed continuity issue, covered in why YouTube may end a stream after an encoder disconnect.
When a stream is already live, use Studio’s current stream management controls to inspect or edit the details that YouTube makes available. Do not assume that a change in Castr’s dashboard has changed the viewer-facing event. After any edit, check the live page again and make sure the title and visual treatment still match what is actually being broadcast.
Keep the workflow maintainable
If you run a channel every day, write down the small set of decisions that repeat: which route you use, where metadata is edited, who changes the thumbnail, and how you confirm the event before sharing it. Keep the note focused on responsibilities rather than obsolete click-by-click screenshots. Interfaces move, but the distinction between Castr’s feed destination and YouTube’s event presentation remains useful.
For a shared operation, decide who is allowed to change the public title and artwork. One person can prepare the event in Studio while another checks the destination in Castr, but both need to refer to the same scheduled stream. This is especially helpful when the channel has multiple recurring programmes with similar titles or when an operator is taking over overnight.
The connection route should fit the way you already manage the channel. The API flow can reduce switching when you want to set title and description during destination setup. Manual connection can remain practical when the event and its metadata are already managed in Studio. Neither route removes the need to verify the thumbnail in YouTube, and neither makes the public-facing details immune to a later edit.

FAQ
Can I upload a YouTube thumbnail in Castr’s destination form?
The reviewed Castr connection guidance does not show a thumbnail upload control in the destination form. Add or change the image through YouTube Studio’s scheduled-stream or live-management workflow, then check that it is attached to the right event.
Does changing the Castr project name change the YouTube title?
Do not assume that it does. Castr’s project name is an internal label, while the YouTube title is event metadata; verify the public title in YouTube Studio after making changes.
Where do I edit the title and description with a manual stream key?
Castr’s guide directs manual-connection users to YouTube’s dashboard for description edits. Use YouTube Studio to manage and verify the event’s title and description, as well as its thumbnail.
Can Castr’s metadata API change a thumbnail?
Castr’s documented social metadata endpoint describes title and description updates for linked destinations. It does not document thumbnail updates, so use YouTube’s own stream management workflow for the image.
