Before changing a video, identify whether it is playing in Castr TV Playout, a standard Castr playlist, or a playlist managed directly in YouTube. The documented procedure differs: TV Playout has a specific restriction for the item marked LIVE, while the reviewed guides for the other two surfaces do not describe replacing an entry in place.
If the current item is live in TV Playout, Castr says to disable the playout before changing it and then apply the timetable again with Set Schedule. If it is only upcoming, it can be changed while the playout continues. For standard Castr and native YouTube playlists, use only the controls their documentation confirms; do not assume that a playing entry can be swapped without interruption.
Identify which playlist or playout is running
“Castr YouTube playlist” can refer to more than one thing. First look at where the list is managed and what is actually sending the broadcast. A list of videos in the Castr dashboard is not necessarily the same workflow as a Castr TV Playout schedule, and neither is identical to a playlist edited in YouTube Studio or on YouTube.
Castr describes its standard playlist as a way to organise selected content into a sequential list. Its guide covers adding content and playback options. TV Playout is a scheduled broadcasting feature: its content is routed to a Castr livestream destination, which may be connected to YouTube. A native YouTube playlist, by contrast, is edited on YouTube and organises videos there. The services may be connected in your overall workflow, but the editing controls are not interchangeable.
Use the interface to identify the surface before you make a change:
| What you can see | Likely surface | What the reviewed documentation says about changing an item |
|---|---|---|
| A timetable or schedule, with an item labelled LIVE | Castr TV Playout | Do not replace or move the live item while playout runs. Disable the playout first if it must change; apply schedule changes with Set Schedule. |
| A content list in the Castr dashboard, with playlist playback settings | Standard Castr playlist | The guide describes adding content and playback settings, but does not document replacing an existing entry during playback. |
| A playlist page managed in YouTube | Native YouTube playlist | YouTube documents removing entries and changing their order; it does not describe an in-place replacement action. |
If you cannot tell which surface is active, do not remove the video just to see what happens. Check whether the broadcast is currently being driven by a Castr schedule, a Castr playlist, or a YouTube playlist, and note which item is on air. This small check matters particularly for a channel that must stay continuous overnight: a mistaken edit can change the wrong list or leave a schedule unapplied.
For the broadcast file itself, it also helps to keep an untouched copy and a clear filename for the replacement. The advice in preparing video files for a 24/7 YouTube loop stream is useful when the new item needs to fit an existing continuous programme. That is a separate concern from whether the active playlist surface allows an in-place edit.
If the item is live in TV Playout
Find the item marked LIVE in the TV Playout timetable before editing. Castr’s TV Playout guide specifically warns against replacing or moving content that is currently playing. Treat that as a restriction on the live item, not as a general instruction that every change to the schedule must wait until the broadcast is off air.
If the live item must be changed, Castr’s documented route is to disable the playout first. Then change the item and reapply the schedule. This is materially different from editing an upcoming entry: the live item is the one whose playback is in progress, so changing its position or replacing it while the playout is running is not the documented procedure.
You may need to decide whether the change can wait for the current item to finish. If the content is simply the wrong version of a devotional programme or an outdated notice, letting it complete may be less disruptive than stopping the schedule now. If it contains an error that should not remain on air, follow the disable-and-change route rather than trying an undocumented live swap. The appropriate choice depends on the content and the channel’s needs; the documentation does not promise a seamless transition when you disable playout.
Before you act, write down the current item and the next item, and confirm that the intended replacement is ready. This is not a Castr requirement; it is a practical safeguard against changing the wrong slot or leaving a gap because the file is not available. If a second person helps run the channel, tell them that you are pausing and applying the schedule so they do not interpret the change as an unexpected failure.
For a channel that loops recorded video rather than relying on a timetable, the distinction between the source file and the broadcast schedule is still useful. The guide to adding a seamless video loop to a 24/7 YouTube yoga stream covers continuity at the loop level; TV Playout’s live-item rule remains the controlling point for a scheduled item currently marked LIVE.
Disable playout before changing the live item
When you have confirmed that the item is live and must be changed now, disable TV Playout before editing that item. Do not treat moving it to another timetable position as a workaround: Castr’s instruction applies to replacing or moving the content that is playing. The order matters because the currently live item is subject to a different rule from the later entries.
Use the current Castr dashboard controls to disable the playout. The reviewed help page establishes the required order, but labels and interface details can change, so follow the wording you see in your account rather than relying on an old screenshot or a guessed button name. If you cannot find the control, stop and consult Castr’s current TV Playout guide or its support team before editing the running item.
Once disabled, make the intended change to the live slot. Check that the replacement is the correct file and that its position in the timetable makes sense relative to the entries around it. If the slot should be removed rather than replaced, check the resulting sequence so the next scheduled item is the one you expect. The point is not to prescribe an undocumented control sequence; it is to make the edit only after playout has been disabled.
Disabling the playout is a deliberate interruption to the scheduled broadcast workflow. Do not assume that viewers will see a particular holding screen, that the stream will remain uninterrupted, or that the replacement will begin automatically. The cited Castr instructions explain when to disable and how to reapply a changed schedule; they do not establish what every viewer will see during the interval. If continuity is essential, choose a suitable time to make the change and verify the broadcast afterwards.
A separate computer or encoder can have its own continuity risks. If your channel is actually being sent from OBS rather than TV Playout, the Castr timetable procedure does not apply. The automatic-startup walkthrough for an OBS YouTube stream concerns that different setup, not a way to replace a TV Playout item in place.
Update the timetable and select Set Schedule
After changing the live item, apply the timetable again by selecting Set Schedule. Castr’s TV Playout guide says to click Set Schedule when changes to the timetable or destination need to be applied. Editing the list and applying the schedule are separate steps: do not assume that a visible edit has already changed the active playout.
Before applying, review the timetable from the changed slot forward. Confirm the intended replacement, the order of upcoming items, and the destination shown for the broadcast. This is especially worthwhile when the edit involved moving rather than replacing an item, because the next entry may have changed as well. Then select Set Schedule and wait for the dashboard to reflect the applied state before you regard the task as finished.
If the destination was not meant to change, avoid changing it just to make the schedule apply. If it was intentionally changed, verify that the selected destination is the one connected to the intended YouTube channel. A timetable can be correct while a destination selection is wrong, so checking both is a practical final review. The guide confirms that Set Schedule applies schedule or destination changes; it does not mean YouTube has approved a broadcast or that every possible connection issue has been resolved.
After the schedule is applied, check the live status and, where practical, view the channel from a separate browser or device. Look for the expected video and audio rather than relying only on the timetable display. If the stream is not behaving as expected, record what the dashboard shows and consult the current Castr support material rather than repeatedly toggling settings without knowing which change took effect.
For channels where the source rotates through repeated recordings, there are other operational checks beyond the edit itself. You can use the guide to YouTube copyright rules for looping nature footage to think through the content rights question separately. Reapplying a schedule is a playback operation; it does not settle questions about whether you have the rights to broadcast a particular video.
What can be changed while playout continues
Castr distinguishes the currently playing item from other content in the TV Playout timetable. Its guide says not to replace or move the item marked LIVE, but says other content can be replaced or moved. That means an upcoming item can be adjusted while the playout runs; it does not mean that every change is safe to make without applying the timetable again.
For an upcoming replacement, identify the entry by its position and status, make the change to that entry, and review the sequence around it. Then select Set Schedule to apply the revised timetable. Do not confuse “the playout may continue while I edit an upcoming item” with “the timetable change is already active”. The scheduling step is part of the documented process.
The distinction can be useful for ordinary corrections. Suppose a local news loop has a scheduled notice later in the day and you notice that the graphic is out of date while another item is on air. If the notice is upcoming, the guide permits changing or moving that other content while playout runs. If the inaccurate graphic is already the LIVE item, the instruction is different: disable first, then change and reapply the schedule.
If the timetable is not clear about which item is live, pause before editing. A thumbnail or title alone may not tell you whether a row is currently on air or only queued. Confirm the status in the current dashboard. Where the interface does not make it clear, ask Castr support rather than infer the state from the order of the list.
These rules apply to Castr TV Playout, not every Castr product with a list of videos. Nor should they be transferred to YouTube’s own playlist editor. The next sections cover what the reviewed guides do and do not establish for those other surfaces.
Standard Castr playlist: what documentation confirms
Castr’s standard playlist guide explains how to create a playlist, add livestream or video-on-demand content, and configure playback options such as autoplay, loop, and shuffle. It is useful for understanding what the playlist does, but the reviewed guide does not explain how to replace an existing entry while it is playing. That is a limit of what the documentation confirms, not proof that no such control exists in every current account.
For that reason, do not follow an invented sequence of buttons or assume that removing and adding a video will preserve playback position. Check the current Castr dashboard for an explicitly documented edit control. If the operation is not clear, use Castr support to ask whether the playlist can replace the selected entry during playback and what happens to the active stream when you do so. You can consult Castr’s standard playlist guide as the official reference for its described controls.
Before seeking help, note which playlist you mean, whether it is currently playing, and what result you need: replace the file, change its order, or remove it. Include the item’s position and whether the stream must remain continuous. This gives support enough context to distinguish a normal playlist edit from the TV Playout procedure. Do not share a stream key or other credentials in a public support post.
If you need a dependable sequence of recorded content, consider whether the standard playlist is the right surface for your workflow, but do not assume that an alternative broadcasting method has the same controls. A channel assembled around a single looping file, for example, has different editing and continuity questions; the guide to looping a video on YouTube Live with FFmpeg describes a different approach and is not a Castr playlist replacement guide.
The practical conclusion is narrow: the reviewed article supports adding content and setting playback options. It does not confirm an in-place replacement of a playing entry. Until the current dashboard or Castr support gives you a confirmed process, treat that operation as undocumented and avoid experimenting on a broadcast you need to keep running.
Native YouTube playlist: remove or reorder instead
If the list is managed directly in YouTube, follow YouTube’s documented playlist controls rather than Castr’s TV Playout instructions. YouTube Help covers removing a video from a playlist and changing the order of videos. It does not describe replacing one entry in place as a single operation.
The documented approach is to remove the old entry using its More menu, then add the intended video to the playlist and check where it appears. You can reorder entries by dragging them in the playlist. Since removing and adding are distinct actions, verify the resulting position instead of assuming the new video takes the old one’s place. Use YouTube’s current desktop playlist instructions and instructions for creating and managing playlists to confirm the controls in the interface you are using.
This is a playlist-management procedure, not a promise that a live broadcast will switch to the new entry immediately. A native YouTube playlist and a YouTube live stream are separate things, even if the playlist is being used to organise content related to a channel. If a Castr schedule is what is actually sending the broadcast, editing a YouTube playlist will not substitute for updating that Castr schedule.
After the change, check the playlist page to confirm that the intended video is present and in the correct position. If you are using a playlist as a viewer-facing collection, check it from the public view as well as the editing interface. If your objective is to change what a running stream is showing, identify the playback source first; do not infer that editing the native playlist controls what is currently on air.
For a continuously running channel, the safest habit is to record which system owns the list and verify the result in that same system. A Castr timetable change needs its schedule applied; a native YouTube playlist change needs its entries checked on YouTube. Neither procedure should be presented as an in-place replacement feature that its documentation does not confirm.
If you are moving from manual changes to a workflow where a prepared video can run without keeping your own computer on, StreamNeo can remove the recurring task of leaving a machine running to sustain the broadcast; it is YouTube-only, so it is not a way to edit a Castr TV Playout or YouTube playlist.

FAQ
Can I replace the video marked LIVE in Castr TV Playout without stopping playout?
Castr’s TV Playout guidance says not to replace or move the content currently marked LIVE. If it must change, disable the playout first, make the change, and apply the timetable again with Set Schedule. The documentation does not promise a seamless switch while it remains live.
Can I change an upcoming TV Playout item while another video is live?
Yes. Castr’s guide permits replacing or moving other content while the playout runs. Review the timetable after the edit and select Set Schedule to apply the change.
Does a standard Castr playlist support replacing a playing entry in place?
The reviewed Castr playlist guide documents adding content and playback settings, but does not document replacing an existing entry during playback. Check the current dashboard or ask Castr support before relying on that behaviour.
Does YouTube have an in-place replacement button for playlist videos?
The reviewed YouTube Help instructions cover removing videos and reordering playlist entries, not an in-place replacement operation. Remove the old entry, add the intended video, and verify its position in the playlist.
