Yes. Castr supports sending pre-recorded videos to YouTube as a live broadcast, including a playlist that repeats in Loop mode. You upload or select MP4 files, choose the looping schedule, connect YouTube, and start or enable the stream.
The important qualification is plan access. Castr’s documentation distinguishes ordinary Loop playback from Infinite Loop, and its product page says Infinite Loop is available on Premium and higher. Check Castr’s current plan matrix for the account you intend to use, including upload, storage, duration, file-count, and playlist limits.
How Castr’s YouTube loop works
A Castr pre-recorded stream does not create a normal YouTube video that each viewer starts from the beginning. Castr sends the file or playlist to YouTube as a live broadcast. A viewer who joins later sees the point currently being broadcast, just as they would with another live stream.
The basic workflow is therefore different from uploading a video to YouTube and turning on an ordinary repeat option. You prepare the media in Castr, select a scheduling mode, add YouTube as a destination, and let the broadcast run. If the schedule is set to repeat, Castr returns to the beginning of the playlist after it reaches the end.
Castr’s help article dated 8 July 2026 describes MP4 as the upload format for pre-recorded streaming. It also says that the permitted file size and number of files depend on the subscription. Those details matter if you are preparing a devotional collection, a long ambience video, a local news loop, or several short business announcements.
Castr documents two relevant scheduling ideas. Loop repeats the playlist. Date & Time starts the broadcast at a chosen time instead of continuously repeating it. A separate Infinite Loop description says that the video is sent to the added platforms repeatedly, 24 hours a day, once the stream is enabled.
That distinction is easy to miss. “Castr can loop a video” does not mean that every Castr plan includes an unrestricted, always-on playlist. Treat the looping function and the plan-specific Infinite Loop entitlement as separate checks. The Castr pre-recorded streaming guide is the best place to confirm the current workflow before you begin.
Prepare MP4 videos in Castr
Start with the files you actually want viewers to see. A single long MP4 can be used, or you can combine several shorter MP4 files into a playlist. For example, a bhajan channel might use one continuous programme, while a shop might use separate product, opening-hours, and contact slides.
Give each file a useful name before uploading. “Morning-bhajans-final-2.mp4” is easier to identify than “export_017.mp4” when you are arranging a playlist later. If you have several versions of the same clip, remove the old versions from your working folder first so that you do not select the wrong one in Castr.
Check the beginning and end of every file. A black frame, an editing watermark, a loud click, or a spoken sign-off that assumes the video is ending can become distracting when the same clip returns. For a playlist, check the join between each pair as well. A short pause may be acceptable for a news loop, but it can feel abrupt in a meditation or music stream.
Castr’s documented format for this workflow is MP4. Do not infer the allowed file size, duration, total storage, or number of files from another streaming tool. Those are service limits, and Castr says they depend on the subscription. Verify the current limits on Castr’s plan page before you export a large file or build a playlist with many entries.
The video itself should also be suitable for YouTube live playback. Keep the picture legible at the size used by your viewers, make speech understandable, and avoid adding information that will be out of date during a long broadcast. If the content contains a date, price, phone number, or event time, decide how often it must be replaced.
If the videos come from different editing projects, compare their dimensions, frame rates, and loudness before uploading. Castr may accept the files, but acceptance does not make a mixed playlist look consistent. The guide on making recorded videos into a low-budget YouTube live stream in India covers the practical planning questions around source files and long-running broadcasts.
Create a pre-recorded stream and playlist
Sign in to Castr and create a pre-recorded stream from the streaming dashboard. The wording of buttons can change, but the intended object is a stream that uses uploaded or previously recorded media rather than a camera or encoder feed.
When Castr presents the media choices, either upload an MP4 or select a recorded video already stored in the account’s library. If you are using more than one file, add each required video to the same playlist rather than creating separate streams for every clip.
Arrange the playlist in the order viewers should receive it. A simple order might be:
- Opening title or station identification.
- Main programme, lesson, music set, or news segment.
- Supporting information such as schedules, contact details, or sponsor material.
- Closing or holding slide, if one is genuinely needed.
The order becomes part of the broadcast, so review it before connecting YouTube. A playlist that starts with a closing slide will repeat that mistake every time it reaches the beginning. For a devotional stream, you might want a short channel identification before the first bhajan. For a local news loop, you might put the update date near the start so that a late-arriving viewer can judge how current it is.
Keep the playlist as short as the content requires, not as large as the account permits. More files create more places for an incorrect order, an outdated announcement, or an awkward transition. On the other hand, a single very short clip may make the repetition obvious. The right choice depends on the type of channel and how often viewers are expected to join.
Before moving on, play the files locally if possible. Check that the first frame is intentional, the final frame does not cut off speech, and the audio does not suddenly become much louder between files. These checks are separate from Castr’s streaming controls and save time later when you are watching the YouTube output.
Choose Loop and connect YouTube
In the scheduling or playback section, select Loop when you want the playlist to repeat. Castr’s scheduling documentation describes Loop as repeating the playlist, while Date & Time is intended for a broadcast that starts at a selected date and time. Choose the mode that matches the broadcast you want, rather than assuming a scheduled stream will continue forever after one start.
If your account shows an Infinite Loop option, check the plan requirement before relying on it. Castr’s product page for pre-recorded live streaming, accessed on 3 October 2026, states that infinite looping is available on Premium and higher. That is a current product claim, not a reason to assume that every account or plan has the same control. Recheck the plan matrix when you set up the channel.
Next, add YouTube as a destination. Castr’s YouTube connection instructions describe two routes: an API connection or manual entry of YouTube’s streaming server and stream key. The exact screen you see can depend on how your YouTube account and Castr account are configured.
For the manual route, copy the stream key carefully and treat it as confidential. Anyone who obtains an active key may be able to send content to the associated live destination. Do not paste it into a public document, a screenshot, or a support message unless the sensitive part is removed. If you think it has been exposed, replace or reset it in YouTube before using it again.
For an API connection, review the permissions requested and make sure you are connecting the intended YouTube channel. A common mistake is to authorise a personal channel when the stream was meant for a business, temple, school, or local-news channel.
Castr’s guide How to Connect YouTube with Castr explains the destination connection. You can also review YouTube’s official live-streaming guidance for current requirements on enabling live streaming and managing the YouTube side of the broadcast.
After adding YouTube, confirm that the destination is enabled for this particular pre-recorded stream. Connecting a destination to the account is not always the same as selecting it for a new broadcast. Look for the destination status inside the stream setup before you save or start anything.
Start or enable the stream
Once the playlist, schedule, and YouTube destination are ready, save the configuration. Castr’s pre-recorded workflow may use separate controls for enabling the stream and starting it. Read the labels carefully: one control may make the stream active, while another may begin the broadcast immediately.
If you want the stream to begin now, use the start control after checking the destination. If the intention is an ongoing loop that begins when enabled, use the documented Infinite Loop workflow available to your plan. If you selected a Date & Time schedule, confirm the time zone and start time instead of assuming it will use the time zone shown on your computer.
YouTube may take a short time to show the incoming feed. That does not necessarily mean the playlist has failed. Open the YouTube live control room or watch page and look for an active connection and a changing preview. Do not judge success only by Castr showing a saved configuration.
The first few minutes deserve attention. Confirm that the picture is moving, the audio is present, and the title and description belong to the correct channel. If the video is intended for a Hindi-speaking audience in India, check that text overlays render correctly and that any schedule shown on screen uses the intended local time.
Keep the computer available during this first test, but do not assume it must remain on once Castr has taken over the broadcast. Castr’s value in this workflow is removing the need to keep a local playback window open. For a channel owner whose concern is a computer that sleeps, reboots, or loses its connection overnight, StreamNeo addresses the separate pain of turning one uploaded file into a monitored, automatically restarted YouTube stream without leaving a computer running.
That does not remove the need to check the YouTube channel, content rights, account status, or current platform rules. It only describes a different operating arrangement for a YouTube-only broadcast.
Check plan limits before building a 24/7 loop
The most important verification step is the plan matrix, not the presence of a Loop button. Castr’s help documentation says pre-recorded streaming settings such as file and media limits depend on the subscription. Its product page, accessed on 3 October 2026, identifies Premium and higher for Infinite Loop. Both points should be checked against the plan you will actually use.
| What to check | Why it affects the setup |
|---|---|
| MP4 upload format | The documented workflow expects MP4 files, so confirm that your exports match it. |
| Maximum file size | A large single programme may not upload even when shorter clips work. |
| Number of uploaded files | A multi-part channel may need more file capacity than a one-video test. |
| Playlist or media allowance | A playlist can be limited separately from the number of files in the library. |
| Stream duration or scheduling rules | A one-time scheduled broadcast is different from a repeating, always-on stream. |
| Infinite Loop eligibility | Castr’s product page says this is available on Premium and higher, subject to current terms. |
| Destination availability | Confirm that YouTube is enabled and that your account can use live streaming. |
Do not fill gaps in the table with assumptions from an older screenshot, a different Castr product, or another provider. Service limits can change, and a plan name alone does not tell you whether a particular upload or playlist will fit. Check the current Castr plan information immediately before subscribing or uploading the final media.
Run a small test before committing a long playlist. Use one short MP4, connect the intended YouTube channel, and observe the live output. Then test the transition into a second file if your final stream will contain several files. This helps separate an account or destination problem from a problem in the media itself.
After the test begins, compare what Castr says it is sending with what YouTube displays. Check the title, thumbnail or preview, audio, picture, and current point in the programme. If you join from another device, you should see the current live position rather than the start of the file. That is expected for a live broadcast.
To confirm the loop, stay long enough to see the playlist return to its first item, or use a deliberately short test playlist. A saved playlist is not proof that the repeat action has occurred. Watch the transition, note whether the first item starts again, and check that YouTube remains connected.
You should also decide how you will notice a failure. YouTube Studio can show the status of the live broadcast, but a dashboard is only useful if someone checks it. For an overnight devotional or ambience channel, arrange a simple morning check: open the watch page, listen for audio, and verify that the current item is changing. For a business channel, also check that prices, offers, and contact information have not become outdated.
If the stream does not repeat as expected
First check the schedule mode. A Date & Time stream may start once rather than repeat continuously. If Loop is selected but the account does not show the expected Infinite Loop behaviour, review the plan requirement and current Castr documentation before changing the media.
Next inspect the playlist itself. Confirm that the files are present, enabled, and in the intended order. A missing file, an upload that did not complete, or a playlist containing only one very short item can make the result look different from what you expected.
Then check the YouTube destination. The stream key may belong to another channel, the destination may not be enabled for this stream, or YouTube live streaming may not yet be available on the account. Castr’s YouTube connection guide and the official YouTube Help pages should be your first references rather than an old setup video.
If the broadcast starts but ends, look at the mode and plan rules before assuming the MP4 is corrupt. A scheduled one-time event, a duration restriction, or an account-level condition can have a different cause from a bad file. Keep a note of the exact time, visible status, and last playlist item when troubleshooting.
For a channel that depends on uninterrupted operation, separate three questions: did Castr read the file, did Castr send a live feed, and did YouTube keep the broadcast available? Testing each stage in that order is quicker than repeatedly replacing the entire playlist.
If the visual design needs supporting text, add it inside the video or through a planned overlay workflow and test it at the loop boundary. The article on sponsored lower-thirds and tickers on a 24/7 loop is useful when repeated announcements must remain readable without interrupting the programme.
Do not treat a long-running loop as permission to reuse any material without checking its rights or YouTube’s current policies. A technical setup can deliver a file successfully while the channel still needs to consider music rights, reused content, local disclosures, and the accuracy of any news or commercial information. For monetisation questions, read the current official YouTube guidance and the practical discussion of pre-recorded live streams and monetisation rather than relying on an automatic promise.
What to verify before leaving it overnight
Use this final sequence after the first successful test:
- The intended MP4 files are uploaded and the playlist order is correct.
- The first and last seconds of each file do not contain unwanted black frames, silence, or obsolete information.
- Loop is selected for repetition, or the account’s eligible Infinite Loop setting is selected where that is required.
- YouTube is connected as a destination and enabled for this stream.
- The stream key or API connection belongs to the intended YouTube channel.
- The live preview shows moving video and audible sound.
- A second device can open the watch page and see the current live position.
- The plan’s current upload, file, storage, playlist, duration, and Infinite Loop terms have been checked.
- Someone knows how and when the channel will be checked after it begins.
If the channel is a long-form station, keep a copy of the final playlist order and the date on which you checked the plan limits. That record makes the next update easier, especially when an old announcement or seasonal programme needs replacing.
Before committing, compare the operating options on the pricing page. When the file and channel are ready, start free — 24-hour trial, no card.
FAQ
Can Castr loop one MP4 video to YouTube?
Yes. Create a Castr pre-recorded stream, add the MP4, select Loop, connect YouTube, and start or enable the stream. The result is a live broadcast, so viewers join at the current point rather than restarting the file from the beginning.
Is Infinite Loop available on every Castr plan?
Do not assume that it is. Castr’s product page, accessed on 3 October 2026, says Infinite Loop is available on Premium and higher, while other upload and playlist limits also vary by subscription. Check the current plan matrix for your account before relying on an always-on loop.
Can I use several videos in one Castr loop?
Castr’s pre-recorded workflow supports adding videos to a playlist and repeating that playlist. Arrange the files in the required order and test the transition between them, while checking the current limit on uploaded files and playlist media before building the final version.
Will YouTube viewers see the video from the beginning?
No. This is a live broadcast rather than an ordinary on-demand upload. A viewer joining halfway through normally sees the point currently being sent to YouTube, so include useful channel identification or context in the video itself if late arrivals need it.
