If you want to send a local prerecorded video to YouTube Live and have it repeat, Wirecast is the better-documented fit: its Windows version 16 guide covers local media-file shots and a Loop end behaviour, and Telestream documents YouTube as an output. Larix Broadcaster is documented primarily for live mobile capture; the reviewed Larix materials do not establish a prerecorded-file or playlist workflow.
That is a comparison of official documentation, not hands-on testing. It does not mean Larix can never play or relay a file in any version, and it does not establish that every Wirecast edition handles media identically. If your source is a phone camera, Larix fits its documented role. If it is an existing clip to be played and looped from a Windows computer, Wirecast has the clearer documented path.
Short answer: documented fit for a prerecorded clip
The deciding difference is the source. Wirecast 16 for Windows describes adding a local media file as a shot, setting what happens when playback finishes, and selecting Loop to start that media again. Telestream also describes YouTube as an available output destination. Those documented steps align with the basic task: play one local clip into a YouTube Live event and repeat it.
Softvelum’s Larix documentation covers publishing to YouTube and configuring a mobile encoder. The reviewed official pages do not explain how to choose a prerecorded file or set up a playlist in Larix. Treat that as an evidence boundary, not proof that no Larix version, workaround or separate workflow can do it.
For a single clip, Wirecast’s documented end behaviours include Loop, Hold and Remove. Loop is the relevant choice when the clip should begin again after it ends. This is different from proving that a collection of different videos will play in a particular sequence: do not assume unattended multi-file playlist behaviour from the single-file guidance alone. Check the documentation for your installed edition and test the intended sequence before relying on it.
The recommendation is narrow. Wirecast is the stronger documented match for local-file playback and looping to YouTube Live. It is not a claim that Wirecast is universally better, easier, more stable or higher quality than Larix. The choice changes if you need to contribute a live camera view from a phone rather than play a prepared file.
What Larix documentation covers
Larix Broadcaster is presented in Softvelum’s materials as a mobile live-streaming encoder. The guidance includes publishing to YouTube, configuring a connection and choosing video-plus-audio mode with a suitable bitrate. YouTube’s encoder help also lists Larix in the context of mobile capture and streaming live. These sources support using Larix for a phone-based live contribution workflow.
They do not, in the materials reviewed for this comparison, give instructions for selecting an existing video file as the source, defining its playback end behaviour, or creating a playlist. That distinction matters if you are planning a devotional loop, a lofi station or a product demonstration from a finished export. Connection instructions for sending live video to YouTube do not by themselves tell you how to turn a stored file into the encoder’s input.
Documentation can be incomplete or change between releases and platforms. A missing instruction is not evidence that a feature is impossible in every Larix version. If you already use Larix and want to check a possible file workflow, look at the current documentation for your app version and device, then verify the exact source controls in the app before scheduling an event. This article does not treat an undocumented workaround as a dependable, supported workflow.
Larix remains a sensible choice when the picture is happening now: a local event, a temple gathering, a shop-floor update or a camera view from a phone. You configure its YouTube publishing connection and send the live feed. For a prerecorded clip, the reviewed sources do not establish those file-selection and looping controls, so Wirecast gives you a more concrete set of documented steps.
What Wirecast documents for local media
The Telestream Wirecast 16 User Guide for Windows documents importing or browsing to a media file and adding that file to a shot. A shot is a source you can put into the production output. For this task, the useful documented controls are the media file itself and the setting for what happens when playback reaches its end.
In the guide’s description of the “When Finished” setting, Telestream says: “Loop causes the media to begin playing again.” The same control offers other end behaviours, including Hold and Remove. Choose based on what the event should show when the clip ends: Loop repeats it, Hold leaves its last frame, and Remove takes it out of the shot. Confirm the exact wording and available controls in the edition you have installed.
The guide cited here is specifically for Wirecast 16 on Windows. Do not assume every detail transfers unchanged to macOS, an older release or a later interface. The useful conclusion is that the cited Windows guide explicitly documents the local-media shot and Loop behaviour. Before you build a long-running workflow around a different edition, consult its current guide and check the relevant settings there.
A single looping file may be enough for a quiet ambience scene, a continuous information board or a repeating programme segment. If you have multiple files, a playlist, transitions or scheduled changes, those are separate production requirements. Verify their behaviour in your version rather than treating “Loop” as a promise that a set of files will be sequenced, restarted or recovered in the way you expect.
For a folder of clips, sequence and continuity questions can become more important than the encoder itself. The guide to streaming a folder of videos from a headless Ubuntu VPS covers a different, command-line approach; it may help you compare the kind of control you need, but it is not a Wirecast instruction. If you only need one source file, avoid adding a more complex workflow unless it solves a real requirement.
Set a clip to loop in Wirecast
On a Windows computer running Wirecast 16, start by locating the finished local file and adding it as a media-file shot using the guide’s import or browse workflow. The interface can differ with edition and layout, so follow the guide for the version you have rather than relying on button names from another release. Before going live, make sure the intended file is the source in the shot and that it plays in the production preview.
Open the media settings for that shot and find the end-of-playback behaviour, identified in the guide as “When Finished”. Select Loop if you want the same clip to restart when it reaches the end. If you want it to stop on the last frame or disappear instead, the guide documents Hold and Remove as alternatives. These settings describe the file’s behaviour at its end; they are not a substitute for checking whether the whole broadcast should remain active or what YouTube will show if the source or connection fails.
Play the clip locally before connecting the event. Check that the picture decodes, the framing is suitable, and the soundtrack is present at a useful level. Listen across the clip’s ending and restart, because a file that loops can still have a silence, abrupt cut or black frame at its boundary. These are practical checks for your own media, not claims about results from a product test.
If the clip is long or the channel is meant to stay on overnight, consider how you will notice a local computer, file or network problem. Wirecast’s file-loop setting only describes what happens when the media reaches its end. It does not establish a guarantee about unattended operation or automatic recovery. For a different workflow that addresses continuity after an outage, see what to check when a cloud YouTube stream does not resume after a brief outage.
Use a file that is stored where the computer can access it for the full session, and do not move or rename it after configuring the shot. Keep a copy of the source and, if it matters, a second export in a known location. A carefully prepared video cannot prevent a power cut or dropped connection, but it makes file-related surprises easier to diagnose separately from YouTube event and network problems.
Configure YouTube as the output
Telestream’s Wirecast guide to streaming to YouTube describes choosing YouTube in Output Settings. Use the instructions for your installed version to configure the destination and connect it to the event you intend to broadcast. The specific screens and account authorisation steps can change, so confirm them in current vendor guidance rather than treating a past walkthrough as permanent.
Before starting the output, check the destination carefully. Make sure the right YouTube account and event are selected, and that the event is set up as intended. A familiar channel name is not enough if you manage several channels or have multiple scheduled events. Review the title, visibility and any event settings in YouTube Studio, then compare them with the output selected in Wirecast.
If you use a stream key or other connection detail, handle it as a credential: do not put it in a public screenshot, chat or shared document. Follow current YouTube and Telestream directions for entering or authorising the output. YouTube’s encoder guidance is the place to check current event and ingest requirements, as account eligibility, settings and interfaces may change.
Sending a signal to YouTube and making an event public are related but distinct steps. Your output may be connected while the event still awaits a preview or a deliberate go-live action in YouTube Studio. Build that pause into your procedure. Do not assume that a successful connection alone means viewers are already seeing the intended broadcast.
For a channel built around several prepared items, confirm whether you truly need multiple clips or whether one edited file is sufficient. A sequence can be assembled into one file before the broadcast, reducing the number of playback transitions to check. If the practical question is how to combine source videos, this guide to joining multiple videos into one file for a YouTube Live stream is relevant to that preparation decision.
Check the YouTube preview before going live
A preview is the last useful check between configuring the source and asking viewers to rely on it. Start the output according to the current YouTube and Wirecast instructions, then inspect the event preview in YouTube Studio. Confirm that the picture is the intended clip, that motion is visible, and that audio is reaching the event. If the preview is blank, silent or showing the wrong source, pause and resolve that before going live.
Check a few moments beyond the opening. If you have time, verify that the clip reaches its ending and begins again as expected, or test the loop locally before the event if you cannot wait for a full-length file. Confirm the aspect ratio, safe framing for any text, and whether a title card or black interval appears. A title or caption that is clear on a desktop can be difficult to read on a phone, which is a common viewing context for audiences in India.
Then check the event details: title, visibility, audience setting and scheduled start. Make sure the preview is attached to the correct event. A production can be technically sending video while an event is mislabelled or configured differently from what you intended. These checks help separate source problems from event-setup problems; they do not guarantee approval, reach or uninterrupted delivery.
If your channel is meant to remain on continuously, make a simple restart and contact plan for the people responsible for it. Decide who can see the event state, who can access the computer, and what you will do if the file stops or the connection drops. A loop setting is useful for repeating media, but it should not be mistaken for a complete monitoring plan.

Choose based on your source and workflow
| Your need | Larix Broadcaster | Wirecast |
|---|---|---|
| Send a live camera feed from a phone | Documented use case in Softvelum and YouTube materials | Desktop production software; not the mobile-capture workflow described here |
| Use a local prerecorded file as the source | Not documented in the reviewed official Larix materials | Wirecast 16 Windows guide documents adding a local media file as a shot |
| Repeat one file at its end | Not established by the reviewed Larix materials | The guide documents Loop as an end behaviour |
| Send output to YouTube Live | Softvelum describes YouTube publishing setup | Telestream documents YouTube as an output destination |
| Best documented fit for this article’s task | Live phone contribution | Local clip playback and looping to YouTube |
Choose Larix when you need to send a live phone camera feed and its mobile setup matches the job. The phone is both camera and encoder, so the workflow suits situations where you need to move or report from the location rather than play an already-produced file. Its documented YouTube publishing guidance gives you a starting point for that job.
Choose Wirecast when the source is a local clip and you want the documented controls for putting it into a shot and looping it. The trade-off is that this puts a Windows desktop production workflow at the centre of the setup, and you need to confirm the guide applies to your edition. If you require a playlist of different items, verify that specific behaviour rather than inferring it from a single clip’s Loop setting.
There is also a difference between choosing software for a scheduled production and choosing how a channel runs when your own computer is off. For the latter case, StreamNeo addresses the burden of keeping a local machine running by turning an uploaded video into a YouTube live stream. That is a separate workflow from controlling a local-file shot in Wirecast, and it is YouTube-only; decide based on whether you need desktop production controls or a prepared file that can run without your computer.

FAQ
Can Larix Broadcaster play a prerecorded video to YouTube Live?
The official Larix materials reviewed here explain mobile live capture and YouTube publishing, but do not document selecting a prerecorded file as the source. That does not prove no Larix version or workaround can do it. Check the current instructions for your app version and test the exact workflow before relying on it.
Is Wirecast better than Larix for looping one video?
For this particular task, Wirecast has the clearer documented fit: the Wirecast 16 Windows guide describes a local media-file shot and a Loop end behaviour. Larix is documented for a different source workflow, live mobile capture. This is a documentation-based comparison, not a measured comparison of reliability or quality.
Does Wirecast’s Loop setting make a playlist of videos repeat?
The cited guide describes what happens when a media file reaches its end; it does not establish unattended sequencing and looping for a playlist of multiple files. Check the current guide for your installed version and test the sequence you intend to use. A single edited file may be simpler if you do not need separate clip controls.
Will choosing Wirecast guarantee that YouTube accepts or keeps the stream live?
No software choice guarantees event approval or uninterrupted delivery. Check YouTube’s current encoder and event guidance, inspect the Studio preview, and confirm the event settings before going live. Plan separately for local computer, file and network interruptions.
