To make OBS play VLC playlist files in filename order, arrange the files in that sequence in the VLC Video Source properties and turn off Shuffle Playlist. OBS plays the configured list in its listed order when shuffle is off; it does not document an automatic sort-by-filename button for this source.
If a bulk selection leaves you unsure about the order, numbered filename prefixes such as 01_, 02_ and 03_ can make the intended sequence easier to follow. They are a practical ordering aid, not an OBS sorting feature: inspect the list OBS actually shows and correct it there before you rely on it for a YouTube Live loop.
Open VLC Video Source properties
In OBS, find the VLC Video Source that contains your videos, then open its properties. The source is a playlist of media items, separate from an ordinary single-file Media Source. If you have not made one yet, add a VLC Video Source to the scene and add the files you want it to play.
The source depends on VLC being installed on the computer running OBS. OBS’s documentation also notes that 64-bit OBS requires 64-bit VLC. If the source type is missing, or OBS cannot use it, check that installation and architecture match before troubleshooting the sequence. The OBS Media Sources documentation describes this source and its playlist controls.
In the properties window, locate the playlist or media-file list. This is the sequence to pay attention to. The order shown in this configured list is the order OBS can play when shuffle is disabled; sorting files in another application does not establish that the OBS list has changed.
A local playlist here is not the same thing as an HLS playlist used in streaming protocols. This guide concerns files configured in OBS’s VLC Video Source, not the structure or ordering rules of an HLS stream. Keep the troubleshooting focused on the source properties rather than changing unrelated streaming settings.
Turn off Shuffle Playlist
Look for Shuffle Playlist in the VLC Video Source properties and make sure it is off. OBS documents the setting as controlling whether media files are randomised or played in file-list order; its default is Off. Confirm the checkbox yourself rather than assuming the default is still in place, because a saved source may have been changed.
Shuffle is the setting that can make a carefully ordered playlist appear unpredictable. With it enabled, the intended first item may not play first, and subsequent files can seem to ignore the sequence you prepared. Turning shuffle off gives you list-order playback, but it does not sort that list alphabetically. You still need to control the sequence displayed in the source.
After changing the setting, apply or close the properties window as appropriate for your OBS version, then check the playlist again. If you have multiple VLC Video Sources in different scenes, verify the source used by the scene that will be live. Adjusting a source that is not in use will not fix the broadcast sequence.
Understand listed-order playback
The direct answer to “make OBS play videos alphabetically” is not a hidden sort command: make the visible source list match the desired filename order, then keep shuffle off. For example, if the intended sequence is Morning.mp4, Noon.mp4, then Evening.mp4, put those entries in that order in OBS. The source follows its configured list rather than independently reading names and rearranging them.
OBS’s published documentation describes the choice between shuffle and file-list order. It does not document an automatic filename sorting control in this source. The OBS source implementation is consistent with treating the configured list as the sequence to manage: its shuffle path reorders that list when shuffle is enabled. This is useful context, but you do not need to inspect source code to configure the playlist.
VLC desktop player sorting is a separate control. VLC supports sorting its own playlists by criteria such as name, but do not assume that sorting a queue in VLC automatically updates the independent playlist in OBS’s source properties. The VLC playlist API documents playlist sort criteria for VLC; it is not a promise that an OBS source imports that order.
This distinction matters for a long-running channel. If you add files in a sequence you have not checked, the first few entries may be wrong even though all the expected files are present. Keep the OBS list as the authority for this source, and use VLC’s own controls only for playlists you are managing inside VLC itself.
Check the actual playlist sequence
Read the entries in the OBS properties from top to bottom and compare them with the order you intend. Do this after adding files, not only before. A bulk selection can make the resulting sequence unclear; rather than guessing which file was added first, inspect the entries OBS displays and move or re-add items until the visible order is right.
For a devotional channel, you might want an opening bhajan before a longer morning set, followed by instrumental items. For a local business, the sequence might place a welcome slide video before product demonstrations and a closing message. In either case, write down the intended order first, then compare it with the source list. A short written sequence is easier to check than a playlist assembled from memory.
Check filenames carefully when two entries look similar. A final and a final-revised file may not be interchangeable, and a duplicate can make the playlist appear to skip content when it is simply playing a second version. If filenames are ambiguous, rename the local files descriptively before adding them, then verify the displayed entries again. Do not infer order from the files’ location in a folder or from the order shown in a separate file manager.
If this playlist points to files on a network-attached drive, check that the referenced files remain available at the same paths. The practical concerns around keeping media accessible are covered in the guide to using a NAS for a 24/7 Indian music stream. That is a storage question rather than a sorting feature, but a correct sequence is only useful if OBS can still read each item.
Use numeric prefixes as a practical workaround
Numeric prefixes are a human-readable workaround when you need to make an intended order obvious. Rename a set of files along the lines of 01_intro.mp4, 02_morning-bhajan.mp4 and 03_instrumental.mp4, then add or arrange them in OBS and inspect the resulting list. The prefixes help you see which entry should come first and reduce confusion when names otherwise sort or display similarly in other tools.
Do not treat the prefixes as a built-in OBS auto-sort feature. They do not make OBS rearrange the configured playlist by filename. If you add files in the wrong order, numbered names do not guarantee that the source list will change to match them; the dependable check is still the order visible in the VLC Video Source properties with shuffle off.
Use a consistent naming scheme if you update the loop regularly. For instance, keep a number at the start of each filename and leave enough space in the naming pattern to insert a new item later. If a new video belongs between items 02 and 03, you can either renumber the set or use a clearly understandable label and then put the entry in the right place manually in OBS. The naming convention is for your own organisation, not a setting OBS reads as an instruction.
Prefixes are especially useful when you prepare files in batches or hand the setup to someone else. They make the planned order legible before the files enter OBS, and the list can be checked against that plan. They do not remove the need to verify the playlist after changes. This approach is similar in spirit to making a deliberate sequence for a loop, as in the guide on looping yoga videos on YouTube Live, while the exact source controls here remain specific to OBS’s VLC Video Source.
Reorder entries when needed
If the sequence shown in OBS does not match your plan, change the entries in that source list. Depending on the OBS interface and how you added the files, remove and re-add them in the intended order or use the available list controls to move entries. Then read the list again from top to bottom. Do not rely on a sort performed in VLC or in a file manager unless you have confirmed the OBS list itself now matches.
For a stable loop, a simple sequence can be easier to maintain than a clever naming scheme. Keep a separate note of the order if you have many files, particularly when changing only a few items at a time. Before replacing or renaming source files, keep a copy of the current playlist information; the playlist backup guide explains why preserving a record can make a source change easier to reverse.
If you need to edit or reorder a queue without restarting video, there is a third-party OBS forum resource called Media Playlist Source. Its listing describes playlist editing and identifies a minimum OBS version and supported desktop operating systems. Plugin listings and compatibility can change, so check the current resource page and confirm that it works with your OBS version before building a live workflow around it. It is an alternative to assess, not a required fix for the VLC Video Source.
A separate playlist plugin may be useful if your schedule changes frequently and list editing is central to your operation. The trade-off is that you add another component to maintain and verify. If the list changes rarely, direct reordering in the VLC Video Source is less to set up. Choose based on how often you edit, then test the exact source you plan to use.
Preview the YouTube output
Before going live, preview the source in OBS and let it advance through the first few transitions. Check that the intended opening file appears, that the next entries follow the planned order and that the image and audio are present. This is operating practice, not a guarantee about how a future session will behave; it catches straightforward setup mistakes while you can still correct them.
Confirm the scene in the OBS preview is the scene you intend to send to YouTube Live. If the playlist is nested in a scene or used by more than one scene, follow the actual path that reaches the output. A correctly ordered source that is hidden or not part of the live scene will not determine what viewers see.
YouTube’s live-stream configuration and policy requirements are separate from this playlist-order workflow. The sources for this guide establish OBS and VLC behaviour, not current YouTube encoder requirements, eligibility or copyright decisions. Check current official YouTube guidance for those matters rather than assuming that a correct local playlist makes a broadcast compliant. Likewise, keep rights and permissions for the media you stream under review; no order setting resolves them.
If a computer-based setup is difficult to keep running overnight, consider the operational trade-off separately from the playlist fix. The guide on cloud streaming versus a PC for YouTube creators in India discusses that broader choice. StreamNeo addresses the specific burden of leaving your own computer running by taking an uploaded video and YouTube stream key for a continuing broadcast that does not depend on your computer being on; it is YouTube-only. That does not change the need to prepare and check the media sequence, or to review YouTube’s current rules.

FAQ
Does OBS automatically sort VLC Video Source files by filename?
OBS’s documented control is the playlist order versus shuffle, not an automatic sort-by-filename button. Arrange the list in the source properties yourself and verify the displayed sequence. Numeric prefixes can make your intended order easier to follow, but they do not enable auto-sorting.
Why do my videos play in a different order from the filenames?
First check whether Shuffle Playlist is on. If it is off, OBS follows the configured file-list order, which may differ from alphabetical filename order if the entries were added in another sequence. Inspect and correct that list in the source properties.
Will sorting a VLC desktop playlist change the OBS source order?
Do not assume so. VLC has sorting controls for its own playlist, while the OBS VLC Video Source has its own configured list; the cited documentation does not establish that one updates the other. For a predictable OBS result, check and arrange the entries in OBS.
Do I need VLC installed for this source?
Yes, VLC must be installed for the VLC Video Source to be available. OBS also specifies that 64-bit OBS requires 64-bit VLC. If the source is unavailable, check the installation and matching architecture before rebuilding the playlist.
