For a continuous YouTube channel that needs scheduled playlists sent to more than one destination, Castr TV Playout has the clearest documented fit in the sources reviewed here. Restream documents scheduled playlists and events with useful automation, but its playlist has a stated duration and video-count ceiling, so treat it as a bounded event workflow unless you verify a current continuous-loop feature.
The deciding questions are not simply which tool can play a file. You need to establish whether it can keep broadcasting as intended, address the right YouTube channels, accommodate your media library and schedule, and preserve output settings that suit your content. The comparison below uses published documentation rather than hands-on testing; features, limits and plan terms can change.
Define what multi-channel scheduling means for you
A “multi-channel” setup can mean two different things. You may want one playlist broadcast to several YouTube channels at the same time, or you may operate separate channels with different files, schedules and destinations. Ask vendors which case their documented channel or destination count actually covers. A service that accepts several destinations does not automatically prove that you can manage several independent 24/7 schedules.
Then separate continuous playout from a scheduled event. A continuous station needs to keep going through a queue or loop, potentially with a recurring programme and handoffs between files. A scheduled playlist event instead starts at a chosen time and has a defined playlist; it may be suitable for a long broadcast, but that alone does not show that it loops indefinitely or supports a multi-day programme.
Make a short inventory before comparing plans:
| Requirement | What to establish before choosing |
|---|---|
| Channel arrangement | One feed to several YouTube destinations, or separate schedules per channel |
| Playout behaviour | Loop until stopped, set end date, or one bounded playlist event |
| Media library | Total runtime, file count, file size and whether live segments are needed |
| Schedule | Start times, recurring pattern, advance scheduling horizon and breaks |
| Output | Resolution and frame rate, and whether settings can be changed later |
| Operations | Whether an encoder must run on a computer you maintain |
This prevents a common mismatch: buying an event scheduler when what you need is a station, or selecting a continuous playout tool before checking whether its plan accommodates your destinations and files. For a first pass at the broadcast mechanics, see how a prerecorded video is sent live on YouTube. The same distinction matters whether you run devotional programming, a study channel or a local information loop.
YouTube remains part of the operating picture whichever scheduler you select. Its encoder instructions explain stream URL and key setup, scheduling in Live Control Room and the encoder workflow. The account must be eligible to stream, and its active-stream limits apply independently of a scheduler’s own destination options. A vendor feature does not override YouTube’s channel or stream-key limits.
Castr: schedule mode, loop mode and destinations
Castr’s TV Playout documentation describes uploading prerecorded video and scheduling prerecorded or live content for a continuous broadcast. It offers Schedule and Loop modes. In practical terms, schedule mode is for arranging content against a programme, while loop mode repeats content until its configured end date. The maximum loop length depends on the plan, so a channel intended to run unattended for an extended period needs a plan check rather than an assumption that every tier has the same horizon.
The destination setup is relevant to a multi-channel operator. Castr’s YouTube connection instructions describe a direct API connection and also the use of custom RTMP platforms with YouTube’s server details and stream key to add more than one YouTube channel. This is useful documented evidence for sending playout to multiple YouTube destinations. The instructions do not establish a guaranteed maximum number of concurrent YouTube channels, however. Do not infer one from the general multistream destination total: ask Castr to confirm how the intended channel arrangement counts against the plan.
The TV Playout workflow also depends on having a livestream destination and media available in the account’s Files tab or through Live-to-VOD. Castr says its cloud playout sends to the connected livestream’s destinations and does not require a local encoder or a computer to remain switched on. That addresses the practical problem of a home PC sleeping, rebooting for updates or losing a connection overnight. StreamNeo removes that particular local-computer burden for a file-based 24/7 YouTube broadcast, but it is YouTube-only and is not a replacement if your workflow needs Castr’s documented multi-destination arrangement or programmed live inserts.
Castr distinguishes a one-file scheduled premiere or loop from a programmed channel built from multiple files and live streams, with breaks and schedules spanning multiple days. That distinction is worth confirming against your own plan. If you are planning a devotional station, the practical questions include whether a live prayer segment must join recorded bhajans, whether there are planned breaks, and whether each YouTube destination gets the same programme. A continuous Malayalam devotional stream workflow is a useful point of comparison for the kind of operational detail that can sit behind a simple “24/7” label.
Castr setup prerequisites and plan boundaries
The most consequential setup qualification is that Castr asks you to choose the playout output settings when creating it. The documented choices include frame rate and resolution; Castr says those settings cannot be changed after creation. Uploaded files are transcoded to match the selected output. Treat this as a design decision, not a toggle to revisit casually once the channel is live.
Before creating a playout, decide on the output that suits the source material and the viewers’ connection conditions. If most files are 1080p at a particular frame rate, do not choose a higher or mismatched output merely because it is available. Transcoding can standardise mixed files, but it cannot make low-resolution source material more detailed. Check a representative sample of your content and confirm with the vendor what changing the output later would require; the documentation says the existing setting itself is immutable.
Plan limits also need careful reading. Castr’s product page says every plan includes one playout channel, while file, loop and output limits scale by plan. It lists multistream destination totals from 6 on Starter to 30 on Ultra and Events, with higher totals available on request. It also describes Premium loop scheduling up to 15 days ahead and Ultra/Events up to 30 days. These are vendor-listed terms from the research reviewed for this article, not a promise that the same tiers or limits will remain available; verify Castr’s current plan page before purchase.
Those details should be mapped to the actual architecture. One playout channel is not necessarily the same thing as one YouTube destination. Conversely, a large multistream destination total is not proof of multiple independent playout channels. If you need three different programmes to run at once on three YouTube accounts, ask specifically whether the proposed subscription supports those concurrent playouts, how custom RTMP destinations are counted, and whether the files and loop duration fit. Get the answer in writing if it is central to the purchase.
Files and end dates deserve equal attention. Gather the total running time of your playlist, the number and size of its files, and the dates through which you want to schedule. Confirm whether the plan’s file limits refer to stored media, each playout, or both, and what happens when an end date is reached. For a lofi station built around long ambient videos, the guide to creating a 24/7 rain sounds and lofi radio stream can help frame the content workflow, but it does not replace checking current product limits.
Restream: scheduled playlists and events
Restream documents a playlist workflow in which you upload videos, order them, preview the playlist and schedule when it goes live. Its help material says an event can start automatically at the scheduled time. That can reduce the need to be at a computer to launch each broadcast, and it makes Restream relevant when the job is a scheduled playlist or event distributed to chosen channels.
The distinction from continuous playout is important. Restream’s documented playlist page gives a maximum duration of 24 hours and a maximum of 40 videos. Those are clear constraints for planning a queue, but they do not establish an unlimited recurring loop. If your requirement is an always-on station, ask Restream whether a current product feature supports continuous repetition and how it behaves at the end of a playlist. Until that is confirmed in current documentation, compare it as a bounded playlist/event option rather than assume it is an infinite scheduler.
Restream supports choosing channels when scheduling an event and documents copying RTMP credentials as well as scheduling file and playlist events. This makes it important to distinguish “send this event to multiple channels” from “run distinct programmes on several channels continuously”. Confirm the exact number of destinations available under the intended tier and whether each channel can have its own independent playlist and schedule. A selection field in an event setup does not by itself answer those operational questions.
Restream’s playlist FAQ says playlists cannot currently blend prerecorded and live content. That is a meaningful limitation if your schedule includes a live host, a prayer session, a news update or a presenter crossing between uploaded segments. For a fully prerecorded queue, this may not matter. For mixed programming, it may rule out a workflow or require a separate production arrangement, which in turn brings a person or encoder back into the process.
Restream duration, video and plan limits
Restream’s help article, dated 25 July 2026, lists Upload & Stream add-on tiers as prerequisites for playlists. It lists Marathon at $79 per month, with a four-hour video library and 1080p maximum, and Media at $239 per month, with a 12-hour library and 4K maximum. The same documentation gives the playlist ceiling of 24 hours and 40 videos. These are prices and limits published by Restream in that dated help article, not a recommendation or a guarantee of current availability. Recheck the current vendor page and billing terms before relying on them.
The limits describe different things. A 24-hour maximum playlist duration is not the same as a four-hour library: library runtime constrains what the tier stores or makes available, while playlist runtime is the upper bound for one scheduled playlist. The 40-video cap is a separate count limit. A long queue of short clips can encounter the file-count cap before its duration cap, while a small number of long videos can reach a library or duration limit first.
A useful check is to write down both the total runtime and video count for one full cycle of your planned content, then compare each figure with the current tier terms. If you expect weekly additions, account for how uploaded files are replaced or removed and whether the library hours count all stored files. Ask whether the schedule can be repeated automatically after its endpoint; do not treat an event’s automatic start as evidence that the playlist restarts itself.
Restream’s plan figures may suit a bounded stream, a daily programme or an event that fits inside the documented constraints. They are less obviously suited to a continuous station whose single playlist must run beyond a day or incorporate more than the stated video maximum. A guide to looping a video on a YouTube live stream explains the viewer-facing concept, but a scheduler’s implementation and plan allowance still need direct confirmation.
Match the tool to the workflow
Use a requirements-first comparison rather than a single “best software” label. Based on the documentation in scope, Castr is the clearest researched fit for continuous scheduled playout to multiple YouTube destinations because it expressly documents schedule and loop modes and a custom RTMP route for adding YouTube channels. Restream is a credible fit for scheduled playlists and events within its documented playlist boundaries. Neither statement substitutes for checking the precise tier and channel arrangement you need.
| Workflow | Better-supported direction in this research | What to confirm |
|---|---|---|
| Continuous loop with a planned end date | Castr TV Playout | Loop duration, file allowance, destinations and schedule horizon on the selected plan |
| Scheduled playlist event with automatic start | Restream | Current add-on requirement, target channels and playlist fits within duration and video caps |
| Several YouTube channels with the same feed | Castr has the clearer documented route | Concurrent destination limit and how custom RTMP targets count |
| Separate continuous programmes on several channels | Not settled by a destination count alone | Number of simultaneous playouts and independent schedules supported |
| Playlist mixing recorded files and live segments | Castr describes programmed channels with live streams; Restream says no mix in playlists | Exact mode, tier, handoff behaviour and any operator involvement |
If your use case is one pre-recorded programme on several destinations, concentrate on destination limits and whether the same feed is acceptable everywhere. If you need different schedules per destination, ask for a demonstration or written product answer that explicitly describes separate concurrent outputs. “Supports multistreaming” can mean one event sent to several places, which is not equivalent to managing a small network of distinct channels.
For a locally encoded workflow, a computer or VPS can remain responsible for playback and reconnect behaviour, but then the operator inherits maintenance and failure recovery. A practical troubleshooting comparison is why a Raspberry Pi FFmpeg YouTube stream can keep buffering. Cloud playout can remove the need to keep that local machine broadcasting, though it does not remove the need to check content, stream status, YouTube restrictions or the vendor’s own plan conditions.
Also consider platform policies independently from scheduling. YouTube’s live streaming eligibility and limits guidance states that a channel must be verified and not have had a live-streaming restriction in the preceding 90 days; it also lists 10 active streams per channel and three per stream key. Those published figures are subject to change, and both limits apply at once. A scheduler cannot create extra YouTube capacity beyond the account limits.
Rights and monetisation remain your responsibility. YouTube’s livestream terms require that you hold the rights needed for live content, including music rights. Its channel monetisation policies discuss inauthentic content and reused content separately; having permission to use material does not itself establish monetisation eligibility. A scheduler automates delivery, not rights clearance or a policy decision.

FAQ
Can Castr send a 24/7 playlist to more than one YouTube channel?
Castr’s YouTube connection instructions describe custom RTMP destinations using YouTube server details and stream keys to add more than one channel. The documentation reviewed does not give a guaranteed maximum concurrent YouTube-channel count. Confirm the destination count and whether your intended layout is one shared feed or separate playouts before choosing a plan.
Does Restream provide an unlimited 24/7 playlist?
The Restream help page reviewed documents a playlist maximum of 24 hours and 40 videos, with playlists requiring Upload & Stream add-on tiers. That supports scheduled playlist events within those boundaries, but does not establish an unlimited recurring loop. Check current documentation directly if continuous repetition is essential.
Can I change resolution or frame rate after creating Castr TV Playout?
Castr’s documentation says the output frame rate and resolution are chosen at creation and cannot later be changed for that playout. Files are transcoded to match the selected output. Set the format deliberately and ask Castr what the migration path would be if your channel’s requirements change.
Do these tools remove YouTube eligibility and rights checks?
No. YouTube’s account eligibility, active-stream limits, content policies and rights requirements still apply. Read the current official guidance before broadcasting, particularly when music or other third-party material is involved.
