Streamlabs Desktop Highlighter lets you capture moments during a live stream and assemble selected clips into a highlight reel afterwards. Set its hotkey and replay duration before you go live, then return to the Highlighter tab when the stream ends to review, trim and export the clips.
This guide stays with the Highlighter tab in Streamlabs Desktop. Streamlabs also uses the name Highlighter in material about its separate Replay app, but the two workflows are not interchangeable; the controls below refer to Desktop Highlighter.
What Desktop Highlighter does
Highlighter is a capture-and-assembly workflow within Streamlabs Desktop. Before your stream, you choose a keyboard hotkey and how much recent footage a capture should include. When something worth keeping happens, press the hotkey. Once the stream is over, open Highlighter to work with the clips you captured and combine selected moments into a reel.
That makes it useful when you are already broadcasting through Streamlabs Desktop and want to save moments as they happen. For example, a music streamer might capture a particularly strong performance or a gaming creator might save a decisive round. The method is less useful if you did not configure it before going live: the documented capture path depends on the hotkey and duration being set in advance.
Highlighter is not a general-purpose editor for every video file on your computer. The official procedure describes capturing moments from a Desktop stream and editing those clips into a reel. Do not assume that it will accept every existing recording or offer every control found in a separate editing product. If your goal is to prepare a long playlist video for continuous broadcast rather than clip highlights, see this guide to preparing a Punjabi music playlist video for 24/7 YouTube streaming; that is a different job from making a short reel.
Streamlabs’ Desktop Highlighter guide is the primary reference for the workflow and names the relevant tab and editing actions. Interface layouts can change, so if a control is not where you expect it, check the current guide rather than substituting instructions for Replay.
Find Highlighter and prepare capture
Open Streamlabs Desktop and select the Highlighter tab in the left panel. Before starting the stream, set the hotkey that will mark a moment and choose the replay duration, meaning how much recent footage the captured clip should cover. Do this while you have time to test the configuration, not after the moment you meant to save has passed.
Choose a hotkey that is easy to reach but unlikely to be pressed accidentally during your normal work. If you control scenes, mute audio or use other shortcuts while live, check that the Highlighter key does not collide with them. The point is not to create a perfect keyboard map; it is to know which key captures a moment and be able to use it without interrupting the stream.
The replay duration is a practical framing choice. A short capture may cut off the setup or ending of a moment; a longer one may include extra material that you later need to trim. Think about how your stream unfolds. A devotional performance may need a lead-in before a chorus, while a fast game moment may need only a little context before the action. There is no single best duration for every channel.
Before going live, make one test capture if your setup and stream format allow it. Confirm that pressing the selected hotkey is comfortable and that the resulting clip includes the kind of context you expect. Do not treat this as proof that every future recording is compatible; it is simply a sensible check of your own workflow. If you also run a continuous playlist, the separate concerns of playback and stream continuity are covered in how to fix audio gaps between videos in a YouTube 24/7 stream.
Capture a recording or moment
Once you have configured Highlighter, go live as usual in Streamlabs Desktop. When a moment happens that you may want to share later, press the hotkey. Highlighter uses the duration you set to capture recent footage, so the action is a marker for a moment that has just occurred, rather than a command to begin a new recording from that point onward.
You do not need to mark every interesting second. Capture moments that have a clear beginning, action and finish, or ones that will make sense to someone who did not watch the full broadcast. A clip of a guest arriving, for instance, may need the greeting and a few seconds of conversation rather than just the first frame. You can remove excess material when trimming, but footage that was never captured cannot be restored through the reel editor.
If you are streaming a quiet format such as lofi or a long ambience loop, think carefully about whether a highlight reel is useful to your audience. A selected moment may be more meaningful for a live performance, a news update or a community event than for uninterrupted background audio. The tool does not decide what makes a good clip; your capture choices do.
After the broadcast, end the stream normally. Then return to the Highlighter tab to open the saved clips. If expected clips are not there, check that you pressed the configured hotkey during the stream and verify the capture setup against Streamlabs’ instructions. Avoid assuming that another Streamlabs product’s recording list or controls apply to this tab.
Review and trim clips
In Highlighter, review the captured clips before assembling a reel. Watch each one through, not just the opening frame. A clip can contain a late reaction, a dead-air pause or an abrupt cut at one end. Decide whether it contributes to the story you want the finished reel to tell.
To shorten a clip, hover over it, choose Trim, then drag the clip’s edges to adjust the selected portion. This is a straightforward way to remove unwanted lead-in or trailing material. Make small adjustments and preview the result; trimming too tightly can make a moment confusing, especially if it depends on a spoken introduction, a musical pickup or a reaction after the main action.
Use the inclusion toggle to leave a clip out without deleting it, when you are unsure whether you want it in the current reel. Delete a clip only when you are confident you no longer need it. Keeping a candidate excluded can be useful if you are testing two possible versions, though you should still make clear choices before export so an accidental toggle does not put an unfinished moment back in.
Check audio as well as picture. A cut made at a visually neat point may interrupt a spoken sentence or leave an abrupt musical ending. If your channel depends on speech or music, listen to the trimmed clip in context. For longer audio programmes, normalising podcast audio levels for a 24/7 YouTube stream addresses level consistency in the source material, while Highlighter’s trimming is about selecting which captured moments make the reel.
Arrange a highlight reel
After reviewing the clips, decide on a simple order before polishing transitions. A useful reel usually has a reason to begin and a reason to end: place an establishing moment first, follow it with the strongest or most relevant material, and finish on a clean close. You can reorder clips in Highlighter and toggle individual clips on or off as you refine the sequence.
The documented reel controls include transition type and transition length, an intro or outro, and background music if wanted. These are choices, not requirements. A simple cut may suit a sequence of news highlights better than a decorative transition. A short intro can identify an event, but a long one may delay the moment viewers came for. Background music can help connect silent clips, but it should not obscure speech or compete with the original sound.
Make one change at a time and preview the assembled reel after each meaningful revision. If every clip has a different transition, the editing may draw attention away from the moments themselves. A consistent approach is easier to follow: use a modest transition treatment throughout, or reserve a stronger change for a deliberate shift in topic.
The intro and outro should support the clips rather than turn a short reel into a second programme. For a local news stream, a concise label and closing card may make the compilation identifiable. For a devotional channel, preserving the performance and its natural sound may matter more than adding extra music. Think about the destination and the audience before adding elements simply because the controls are available.
Export and check the result
Preview the full assembled reel before exporting. Watch for a clip that was accidentally left out, a transition that feels too long, an intro that overwhelms the opening, or an abrupt audio change. A preview is the opportunity to catch these editorial problems while the project is still in the Highlighter workflow.
When you are satisfied, click Export and choose the available export settings. Streamlabs’ Highlighter instructions do not establish one universally correct preset, aspect ratio, bitrate or social-platform configuration, so choose settings appropriate to where you plan to publish. If a destination has current requirements, consult that platform’s own guidance instead of relying on a setting recommendation copied from an unrelated workflow.
Once the export finishes, locate the downloaded reel and play it outside the editor. Check the beginning and end, listen for unexpected silence or clipped sound, and confirm that the file is the version you intend to publish. This independent check catches mistakes that may be easy to miss while repeatedly previewing inside an editing screen.
Upload the downloaded reel to the social channel you chose. Keep the original stream recording if you may want to make a different cut later, and give the exported file a name that makes it easy to distinguish from drafts. If the reel is part of a larger channel plan, the advice in how to start an online radio station livestream on YouTube in India can help with the wider broadcast format, but it does not replace checking the requirements for the platform where this particular reel will appear.
Desktop Highlighter versus Streamlabs Replay
Streamlabs has material about a separate Replay app, and some Streamlabs content uses “formerly Highlighter” wording in connection with Replay. That naming overlap is a reason to check the product named in the instructions, not a reason to treat the app and the Streamlabs Desktop tab as the same interface. This article’s sequence—set a Desktop hotkey and duration, capture during a stream, return to the Desktop Highlighter tab, trim and assemble clips—is based on the Desktop Highlighter guide.
Replay documentation describes a distinct app and its own capabilities. Those descriptions may include features or controls that are not established for the Desktop Highlighter tab. Do not follow a Replay tutorial expecting its buttons, automated capture behaviour, subtitles, export shapes or other options to appear in Desktop Highlighter. Likewise, a Desktop Highlighter instruction about the left panel or its capture hotkey should not be presumed to describe Replay.
If you are unsure which instructions match your installation, verify the product and version shown in the current Streamlabs documentation before beginning. Streamlabs’ Replay introduction explains the separate product context. Use the direct Desktop guide for the tab workflow covered here.
For a broader imported-media editing task, Streamlabs also publishes a separate Video Editor guide. That is an adjacent route when you need a general editing workflow, not a prerequisite for turning Desktop Highlighter captures into a reel. The choice is about scope: Highlighter is built around moments captured from a Desktop stream; a general editor may be more appropriate when you are assembling assorted source files or need a different editing process. Check current product documentation for the controls and any plan limits before relying on them.
If your real objective is to keep a YouTube channel broadcasting a fixed video continuously, a highlight reel is not the same thing as an always-on loop. The workflow and operational questions differ; for another broadcast application, see how to run a 24/7 live stream on YouTube with PRISM Live Studio. Choose the editing tool for the task at hand rather than combining steps from unrelated products.

FAQ
Can I use Highlighter on a stream that has already ended?
The documented workflow is to set the capture hotkey and duration before going live, use the hotkey during the stream, then return to Highlighter after ending it. It does not establish that you can import any past recording and create clips from it in the Desktop tab. If you have an existing video file, check a suitable general editor’s current instructions instead.
Where do I trim a clip in Streamlabs Desktop Highlighter?
Hover over the clip, choose Trim, and drag its edges to shorten the selected footage. Preview the result so you do not cut away context, speech or the ending of a musical phrase. The exact screen presentation can vary, so consult the current Desktop Highlighter guide if the control is not visible.
Is Streamlabs Replay the same as Desktop Highlighter?
No. Streamlabs describes Replay as a separate app, while the workflow here is specifically for the Highlighter tab in Streamlabs Desktop. Some names overlap in Streamlabs material, so confirm which product a guide covers before following its controls.
Which export setting should I choose?
There is no universally best setting established by the Desktop Highlighter guide. Choose from the settings shown in your version of the product based on the destination, and check that destination’s current requirements. Play the downloaded reel before publishing to confirm it exported as intended.
