If your OBS playlist contains local video files, you can make lower-resolution copies and use those copies in a VLC Video Source instead of loading the originals. This can reduce the media decoding burden when the playlist does not need to display full-resolution footage, though it does not guarantee a particular performance improvement.
Here, “proxy” means an ordinary smaller, transcoded copy for playback in OBS. It is not an OBS-generated editing proxy, and this workflow is not for a playlist made from YouTube URLs: use local files unless you have separately verified another playback method.
What this playlist workflow assumes
The steps below assume the videos are stored on your computer or another location that OBS can access as local media. The playlist is a list of those files, not a list of YouTube watch-page links. That distinction matters because OBS documents playlist playback through its VLC Video Source, not direct ingestion of a YouTube playlist URL.
OBS’s Media Sources guide describes the VLC Video Source as using VLC libraries for extended media support beyond the built-in Media Source. VLC must be installed for that source to work. If you use 64-bit OBS, OBS says to install 64-bit VLC as well; matching architectures helps avoid a source that cannot load its required libraries.
The word “proxy” can also mean a low-resolution copy made by an editing programme, linked to a high-quality original for editing and later relinking. That is a different workflow, and the reviewed OBS documentation does not establish a native OBS feature for generating editor proxies. For an OBS playlist, prepare regular video files with the dimensions and encoding you want, then add those files to the playlist.
If you actually need a rotating schedule with separate daytime and nighttime content, the question is broader than file size. A 24/7 playlist scheduling guide can help you think through the programme structure; the file-preparation steps here apply to whichever local items you choose to play.
When lower-resolution copies help
A lower-resolution copy is worth considering when the original file has more pixels than your scene and stream output need. For example, a 4K video displayed in a 1080p scene may carry more source detail than viewers can receive from that output. OBS’s encoding performance troubleshooting guidance recommends using lower-resolution media files where appropriate, including when displaying 4K media in a lower-resolution output.
This is not a promise that a smaller file will fix every dropped frame or overloaded system. Playback involves decoding, scene composition and encoding, among other work. The reviewed OBS documentation does not give a benchmark for how much a lower-resolution copy saves, so test your own scene and machine rather than assuming a percentage gain.
There are two different adjustments to consider. If every source in the broadcast can be delivered at a smaller resolution, change the output setting in OBS. If only selected playlist files are unnecessarily large, make smaller copies of those files and substitute them in the playlist. You can use both approaches, but neither changes the other’s purpose.
| Approach | What changes | Useful when | Trade-off |
|---|---|---|---|
| Output (Scaled) Resolution in OBS | Stream or recording output resolution | The whole broadcast can be sent at a lower resolution | All scene content is scaled for the output; this does not create smaller source files |
| Lower-resolution media copies | The files used by selected playlist items | One or more local files are larger than their display needs | Copies take preparation and storage, and re-encoding may reduce image quality |
OBS’s overview of settings explains that Output (Scaled) Resolution controls the stream or recording resolution and uses the selected downscale filter. Changing Base (Canvas) Resolution is different: it can require you to realign or resize sources. If your scenes are already arranged correctly, do not change the canvas simply to reduce the output size without checking the layout.
For the larger context of source and output settings, the guide to configuring OBS for a 4K YouTube stream discusses why a high-resolution source, canvas and delivered stream are not interchangeable choices. You may want a high-resolution final broadcast; in that case, smaller copies could be the wrong trade-off for footage that needs its detail.
Choose which local files to prepare
Do not batch-convert everything just because you can. Start by reviewing the playlist and identifying the files that are both demanding and displayed smaller than their original dimensions. A static devotional image with gentle motion, an ambience loop shown across the whole canvas, and a detailed local news clip can have different quality needs even if each is a video file.
For each candidate, check the resolution and watch a representative section in the actual scene. Look at small text, faces, fine patterns, gradients and movement. A lower-resolution version may be adequate for a wide shot or soft background but make captions difficult to read. If the video fills the frame, the reduction is more visible than when the same footage is a small inset.
Make a short list with the original filename, intended display size and decision. Keep originals in a separate folder and put the prepared copies in a clearly named folder, such as playlist-720p. A simple naming pattern such as morning-aarti_720p.mp4 makes it less likely that you will accidentally remove the original from a working playlist or overwrite a source you may need later.
Also check whether the source is actually the problem. If OBS struggles only when several scenes are active, converting one clip may not address the cause. If playback is smooth but the encoder is overloaded, output or encoding settings may be more relevant. OBS’s troubleshooting guidance is a useful starting point for separating media playback pressure from encoding problems.
Some channels use a fixed programme file repeatedly, while others rotate through many items. If your plan is to loop a music playlist in OBS for a 24/7 YouTube stream, prepare and test every file that will appear in the recurring set, not just the first item. Different codecs, frame sizes and audio tracks can produce different results when the next playlist item begins.
Create compatible copies
FFmpeg can make a smaller copy by decoding the input, resizing the video and re-encoding it. Its documentation describes transcoding as decoding and re-encoding streams, while its scale filter documentation explains how to constrain output dimensions while preserving the aspect ratio. Because video re-encoding is lossy, keep the original and check the result before using it.
An illustrative command for a local MP4 is:
ffmpeg -i "original.mp4" -vf "scale=1280:720:force_original_aspect_ratio=decrease" -c:v libx264 -crf 23 -preset medium -c:a copy "proxy_720p.mp4"
This example scales the picture to fit within 1280 by 720 pixels while preserving its aspect ratio. If the source is not widescreen, the output picture will not be stretched to fill that exact rectangle; it will fit inside it. That helps avoid distortion, though depending on the source and your scene, the result may leave unused space or need a deliberate crop or layout adjustment.
The encoder options are examples, not universal recommendations. libx264 selects a video encoder, crf is a quality-oriented setting, and preset balances encoding speed against compression efficiency. The right choices depend on the quality you can accept and how long the conversion can take. If you adjust them, create a test copy first and inspect the result. The example copies the audio stream rather than re-encoding it; this is convenient when FFmpeg can copy that stream, but an input with unusual audio may need a different treatment.
Run the command on one file before preparing a whole folder. Confirm that FFmpeg completes without an error and that the output is written to the intended location. Open the copy in a media player and check the start, a section with movement, and the end. Listen for the presence and timing of audio, and inspect any text that viewers need to read. If the result is visibly too soft or the sound is absent, keep the original in the playlist while you adjust the conversion.
The command creates a standard transcoded video copy, not a special OBS proxy format. If you mean editor-linked proxies for a separate video-editing programme, consult that editor’s own proxy and relinking instructions; the OBS playlist steps here do not configure an editing project.
Add the files to an OBS VLC Video Source
Once you have tested the copies, add them to OBS through the VLC Video Source. Install VLC first, using the architecture that matches OBS. In OBS, add a VLC Video Source to the scene, then use its playlist controls to add the prepared local files. The precise labels may vary by OBS version, so use the source’s visible controls rather than relying on an old screenshot.
Keep the originals and the copies in stable folders after adding them. Moving or renaming a file can break the path OBS uses to find it. If you organise media on an external drive, make sure that drive is mounted and available before you open OBS and start the broadcast. Consistent filenames also make it easier to find the right copy when you later update a playlist.
The VLC Video Source includes playback options such as looping and shuffling, alongside controls for visibility, caching, audio tracks and subtitles. Set only the options that match the programme: shuffle is useful for a varied ambience rotation but not for a news sequence that must run in order. Check that the source is visible in the scene and sized appropriately. OBS’s Sources guide covers adding a source and positioning or resizing it in the scene.
For a single video rather than a playlist, OBS also has a built-in Media Source. Its available options differ from the VLC Video Source, so choose the source type based on whether you need a playlist and the formats you need to play. Do not assume that making a file smaller changes its path, playlist order or scene layout; those remain separate parts of the setup.
Test playback and performance
Test the playlist before using it in a live broadcast. Play the full sequence if it is short, or at minimum let it pass through each type of file and several transitions. A copy can play correctly in a desktop media player but still reveal a missing path, unsuitable audio-track selection or transition problem in the OBS scene.
Watch OBS’s status and preview while the source is active. Check that video advances, the intended audio is audible, and the scene remains composed as expected. If your programme uses subtitles, overlays or small text, inspect those as well. The goal is not merely to make playback work, but to establish that the lower-resolution version is still suitable for what viewers need to see.
Compare the test with the original under the same scene and output settings. If the smaller copy looks too soft, prepare a less aggressive reduction or retain the original for that item. If both versions perform poorly, the cause may be elsewhere in the scene or encoding path. Change one thing at a time so you can tell whether a result came from the source file, output resolution or another setting.
A 24/7 channel also needs a recovery routine. Keep a record of which copy replaced which original, and leave the original available if you need to roll back. Test again after any change to the playlist folder, OBS profile or scene layout. OBS’s Quick Start material recommends testing settings before streaming or recording; a short local test is less costly than discovering a broken source after you have begun a long broadcast.
If keeping a computer running and watching for playback interruptions is itself the difficult part of a continuous channel, StreamNeo can remove that specific burden by letting you upload a video, provide your YouTube stream key, and run the broadcast while your computer is off. It is for YouTube only; it does not turn an OBS local-media playlist into a YouTube URL playlist.

FAQ
Does OBS create proxy files for this playlist?
The workflow described here does not use OBS to generate proxies. Prepare ordinary smaller video copies with a tool such as FFmpeg, then load those local files into the VLC Video Source. Editor-generated proxies are a separate workflow handled by the relevant editing application.
Can I paste a YouTube playlist URL into the VLC Video Source?
This guide is for local files, and the reviewed OBS documentation does not establish direct YouTube playlist URL playback in the VLC Video Source. Add files stored where OBS can access them. Do not treat a YouTube playlist page as equivalent to a local media playlist.
Should I reduce the OBS output resolution or make smaller files?
Use Output (Scaled) Resolution when the whole stream or recording can be delivered at a lower resolution. Prepare smaller copies when particular local files are unnecessarily large for their role in the scene. You can combine the two, but test the picture and playback after either change.
Can I delete the original after making a smaller copy?
Keep it. Re-encoding can lose detail, and the copy may not meet your needs until you have tested it in OBS. Retaining the original gives you a reliable way to return to the previous version or prepare a different copy later.
