Both Dacast and Castr can send video to YouTube, but they document different ways of doing it. Castr describes both continuous live-source streaming and a prerecorded file that loops to YouTube, while Dacast Simulcast forwards an existing encoder channel and publishes monthly Simulcast hour allowances.
That makes Castr the closer documented fit for an uploaded-video loop, but not an automatic choice for every channel. If you already operate a live encoder feed, Dacast may fit your workflow, provided its current Simulcast terms support the schedule you need.
The short answer: compare the workflow first
The important difference is not simply which service has the lower displayed price. It is what each service expects to be running before YouTube receives the stream.
With Dacast, you create an encoder live channel first. You then attach YouTube as a Simulcast destination. Dacast forwards that existing channel; Simulcast does not create the live source for you. The Dacast API documentation describes Simulcast as being attached to an existing channel.
With Castr, you can connect YouTube to a live source, or use its separate prerecorded-video workflow. Castr's help centre describes a file being uploaded and looped continuously to YouTube without a live encoder or source. That distinction matters if your channel is a devotional playlist, study loop, ambience video or local information board that does not change in real time.
For a camera, studio or remote production feed, compare the encoder and destination requirements on both services. For one uploaded programme that should repeat through the day and night, Castr has the clearer documented route. For Dacast, ask for written confirmation that the specific plan or a custom arrangement covers the exact recurring schedule, rather than interpreting its Simulcast allowance as proof of uninterrupted 24/7 service.
What “always-on” means for a YouTube channel
An always-on channel is not just a video that plays for a long time. It is a chain of dependencies: the programme source, the streaming service, the YouTube connection, the account, the available bandwidth, and the rules applied by YouTube.
A live-source channel might use a camera, an encoder, a production system or a computer running a playlist. If that source stops sending data, the hosted service cannot reproduce the missing feed unless a separate fallback has been configured. A prerecorded loop has a different failure mode: the file, playlist or scheduled event may continue, but the service still needs to maintain the connection to YouTube.
YouTube is also part of the operation. Its stream settings, account status, ingest behaviour and live-stream policies remain relevant after you connect a third-party service. Before comparing vendors, complete YouTube's own preparation steps in YouTube's live-streaming help, including checking whether live streaming is enabled for the channel.
For an India-based operator, think about the shift in responsibility. A laptop in a flat may be affected by power cuts, a sleeping computer, a router restart or an internet provider change. A hosted workflow can remove the need to keep that particular laptop running, but it does not remove the need to test the source, account connection, content and destination settings.
If your current setup stops after a few hours, first identify where the break occurs. The stream may have ended at YouTube, the encoder may have stopped, or the service may have reached a plan limit. The troubleshooting steps in how to fix a YouTube 24/7 stream that stops after a few hours are useful before moving platforms.
How Castr handles continuous and prerecorded streaming
Castr documents two workflows that should not be confused.
The first is continuous streaming from a source that remains live. Its help centre says that an event can continue while the subscription is active and there is enough streaming bandwidth, with the source remaining live. In practical terms, Castr receives the feed and passes it to the selected destination. If the camera, encoder or other source goes offline, the service is not receiving fresh programme data.
The second is prerecorded live streaming. Castr describes uploading a video and scheduling or looping it continuously to YouTube and other destinations. It says this mode does not need an encoder or live source. That is the more relevant description for a channel built around a fixed bhajan programme, a long lofi visual, a study timer or a repeating local notice loop.
Castr's YouTube setup supports either connecting the relevant account or entering YouTube's server and stream key details. The Castr guide to connecting YouTube should be checked during setup because menu names and connection steps can change.
The prerecorded route still has limits. Castr's plan information includes limits relating to concurrent streams, destinations, bandwidth, storage and file duration. A single file that is longer than the permitted duration may need to be divided into parts, or you may need to confirm whether a playlist can be used for the intended schedule. Do not assume that the phrase “continuous” overrides those plan-level constraints.
There is also a content question. Repeating a file does not automatically make the programming suitable for YouTube. If your channel uses music, stock footage, religious recordings, news clips or third-party video, you need the appropriate rights and should review YouTube's current policies. For a practical discussion of repeated programming, see reused content and 24/7 loops.
How Dacast Simulcast works with an encoder channel
Dacast's Simulcast feature is a destination function. You first create an encoder live channel in Dacast, configure the encoder to send its feed there, and then add YouTube as a destination. Dacast remains the origin for the incoming channel while YouTube receives the forwarded stream.
That can be a sensible arrangement when you already have a live production process. For example, a local news team may have a computer running a scheduled bulletin, or a small business may have a studio encoder that is already sending a feed to Dacast. Adding YouTube as a destination may be easier than rebuilding the whole production path.
It is not the same as uploading one file and asking the service to generate a continuous YouTube broadcast. The research for this comparison establishes Dacast's general VOD-to-Live capability, but does not establish that a standard Dacast plan continuously loops an uploaded file to YouTube in the way Castr's prerecorded-live documentation describes.
There is a configuration detail worth recording before you begin. Dacast's support material warns that the encoder ingest URL changes when Simulcast destinations are created. After adding or changing destinations, recheck the encoder configuration rather than assuming its old ingest address remains correct. This is a setup dependency, not evidence that the service is unreliable.
The destination itself also remains subject to YouTube. Dacast notes that the feed can play on YouTube, but problems and limitations on the destination platform depend on that platform. You should therefore test the complete path: encoder to Dacast, Dacast to YouTube, and YouTube playback on the devices your viewers use.
If you are building the source yourself with FFmpeg, a VPS or a spare computer, Dacast may be one component in a larger arrangement rather than a complete replacement for the source. The guide to running a 24/7 YouTube stream without keeping a laptop open in India explains the operating trade-offs of hosted and self-managed approaches.
Duration, hours and plan limits
The most important caution with Dacast is its published Simulcast allowance. Dacast's current pricing and support material list 5 Simulcast hours for Starter, 10 for Event, 28 for Scale and 40 for Custom. The support article says these hours reset monthly and unused hours do not roll over. These are vendor-published allowances, not an independent test of service performance.
Those figures should not be read as evidence that any of the listed plans provides an uninterrupted 24/7 YouTube schedule. A channel that needs to run continuously should ask Dacast whether the intended source, destination, monthly duration and account arrangement are supported. Get the answer for the actual plan in writing before moving a public channel.
Castr's documentation takes a different approach to duration. Its 24/7 help article says continuous streaming is supported while the subscription is active and has enough streaming bandwidth, with the source remaining live. Its prerecorded-live documentation separately describes looping an uploaded file. You still need to reconcile that feature with the limits of the plan you choose.
The following figures are snapshots from the vendors' published pages, accessed in October 2026. Prices and plan terms can change, so treat them as a comparison point rather than a quotation.
| Service and plan | Published price | Published bandwidth and storage | Other relevant published limits |
|---|---|---|---|
| Dacast Starter | $39/month billed annually, as listed on Dacast's site in October 2026 | 2.4 TB annual bandwidth; 500 GB storage | 5 monthly Simulcast hours |
| Dacast Event | $63/month billed annually, as listed on Dacast's site in October 2026 | 6 TB upfront bandwidth; 250 GB storage | 10 monthly Simulcast hours |
| Dacast Scale | $165/month billed annually, as listed on Dacast's site in October 2026 | 24 TB annual bandwidth; 2,000 GB storage | 28 monthly Simulcast hours |
| Dacast Custom | Quote, as listed on Dacast's site in October 2026 | Terms vary | 40 monthly Simulcast hours listed; confirm the arrangement |
| Castr Starter | $19.99/month, or $16.67/month billed annually, as listed on Castr's site in October 2026 | 200 GB monthly bandwidth or 2.4 TB annual pool; 100 GB storage | 2 monthly or 3 annual streams; 6 destinations |
| Castr Standard | $49.99/month, or $41.67/month billed annually, as listed on Castr's site in October 2026 | 500 GB monthly bandwidth or 6 TB annual pool; 200 GB storage | 2 monthly or 3 annual streams; 10 destinations |
| Castr Premium | $199.99/month, or $166.67/month billed annually, as listed on Castr's site in October 2026 | 3 TB monthly bandwidth or 36 TB annual pool; 2 TB storage | 5 monthly or 10 annual streams; 20 destinations |
| Castr Ultra | $349.99/month, or $291.67/month billed annually, as listed on Castr's site in October 2026 | 5 TB monthly bandwidth or 60 TB annual pool; 3 TB storage | 10 monthly or 15 annual streams; 30 destinations |
Do not compare these numbers as though they measure the same thing. Dacast's Simulcast hours describe a destination allowance attached to an encoder channel. Castr's stream, destination and bandwidth figures describe different parts of its service. A low monthly price can still be unsuitable if your viewers, bitrate, files or number of destinations exceed the included resources.
Castr's pricing page also advertises a 99.9% uptime SLA, as listed on Castr's site in October 2026. That is a vendor-stated service commitment, not an independently measured uptime result and not a promise that your YouTube broadcast will never stop.
Work out the resources before choosing
Bandwidth is often misunderstood because the viewer's playback is part of the calculation. A channel sending one feed to YouTube has an outgoing path from the source or service, while YouTube then delivers playback to viewers. A multi-destination workflow adds more delivery requirements within the service. Ask each vendor how its published bandwidth is counted for the exact workflow you intend to use.
Write down the expected video bitrate, audio bitrate, hours per day, number of destinations, file size and expected viewer pattern. You do not need a complicated spreadsheet. You do need to distinguish one YouTube channel from several destinations, and one programme file from a library that needs storage.
For example, a single devotional loop going only to YouTube has a different resource profile from a live camera feed sent to YouTube, Facebook and a website. The second arrangement consumes more destination capacity and may have different concurrency requirements. It is not enough to see that both plans mention “live streaming”.
Storage matters for prerecorded workflows. If your playlist consists of several large files, check whether storage is measured against the originals, the processed versions or both. Confirm the maximum duration of an individual file and whether a playlist can continue after one item ends. If the file must be split, test that the hand-off does not create an unwanted gap.
Concurrency is another common source of confusion. A plan may allow several streams, destinations or events, but those words may refer to different limits. Ask whether your YouTube channel counts as one stream, whether a second test stream uses another allowance, and whether a scheduled prerecorded broadcast counts differently from a live-source event.
Questions to verify before committing
Ask Dacast these questions:
- Does the current plan support the exact number of YouTube hours required each month?
- Are the published Simulcast hours a hard monthly limit for this use case?
- What happens when the allowance is reached, and can a custom arrangement support continuous operation?
- Must the encoder remain live for the complete schedule?
- Does adding YouTube change the ingest URL, and what must be reconfigured afterwards?
- Which bandwidth, storage and destination charges apply to the source and the forwarded feed?
Ask Castr these questions:
- Does the selected plan permit the intended prerecorded file duration and playlist structure?
- How are continuous prerecorded broadcasts counted against stream concurrency?
- What bandwidth is included for the expected bitrate and YouTube schedule?
- Can the channel use a YouTube account connection, a stream key, or both?
- What happens when a source disconnects or a file reaches its end?
- Are there any restrictions on the number of simultaneous YouTube channels or destinations?
Ask both vendors for a short test using your real file or source. A test should include the YouTube account you intend to use, the intended resolution and bitrate, and the longest practical run you can manage. Watch the result from a separate device, check audio, confirm that the title and thumbnail behave as expected, and inspect what happens after a source interruption.
Keep a record of the plan name, billing term, included resources and the vendor's answer about continuous operation. Pricing pages can change, and a screenshot without the date may not explain which terms applied when you made the decision.
Which workflow fits which creator
Castr's documented prerecorded mode is a close fit for a creator with one or more uploaded programmes and no need for a live encoder. That includes a bhajan channel with a prepared devotional loop, a lofi station with a long visual, or a study channel that uses a fixed sequence. You still need to match file duration, storage, bandwidth and concurrency to the selected plan.
Castr's live-source mode may suit a creator whose camera, mixer or encoder is genuinely live throughout the schedule. In that case, the advantage is not that Castr creates content for you. It is that its documentation explicitly addresses continuous streaming while the subscription, bandwidth and source conditions remain satisfied.
Dacast may suit a broadcaster that already uses an encoder live channel and wants YouTube as an additional destination. A local news operation with a production workflow, or a business with an established live feed, may value that structure. The decision depends on whether the current Simulcast allowance and commercial terms cover the planned schedule.
Dacast is a weaker documented match for the narrow requirement “upload one file and loop it continuously to YouTube without a live source”. The material reviewed for this comparison does not establish that standard-plan workflow. That does not rule out a custom solution, but it does mean you should confirm it rather than infer it from general VOD-to-Live features.
A self-managed VPS or a spare computer may be better for someone who needs fine control over FFmpeg, playlists, overlays and restart scripts, and is willing to maintain the system. It also puts power, operating-system updates, network failures and troubleshooting back on the operator. A hosted route is more attractive when the main goal is to upload a finished file, connect YouTube once and avoid leaving a personal computer running overnight.
For a simpler upload-and-repeat workflow, StreamNeo removes the need to keep your computer switched on: you upload the finished video, provide the YouTube stream key, and the channel is run and monitored for you with automatic restarting if the broadcast drops. It is YouTube-only, so it should be considered for that specific workflow rather than for a multi-destination broadcast operation.
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 stream a prerecorded video to YouTube continuously?
Castr documents a prerecorded-live workflow in which an uploaded file can be scheduled or looped continuously to YouTube. The relevant plan's file-duration, storage, bandwidth and concurrent-stream limits still apply, so check those against your programme before subscribing.
Can Dacast Simulcast provide a 24/7 YouTube stream?
Dacast Simulcast forwards an existing encoder live channel to YouTube. Its published plan details list monthly Simulcast hour allowances, so those figures do not by themselves establish uninterrupted 24/7 service. Ask Dacast to confirm the exact schedule and plan arrangement you need.
Do I need an encoder with Castr?
You need an encoder or live source for Castr's live-source workflow. Castr separately documents a prerecorded mode that uses an uploaded file and does not need a live encoder, although the plan and file restrictions still need checking.
Which service should a small YouTube channel choose?
Choose based on the source you actually have. Castr is the closer documented match for an uploaded file that should loop without a live source, while Dacast may fit an existing encoder channel that needs YouTube as a destination and has confirmed Simulcast terms.
