To crossfade prerecorded videos during a continuous YouTube Live broadcast, keep OBS Studio streaming and transition between scenes: put each clip in its own scene, select Fade as the scene transition, set its duration, and switch to the incoming scene when ready. An OBS playlist can play clips in sequence, but its documented controls do not provide an automatic crossfade between playlist items.
This guide covers local video files played through OBS—not a playlist on YouTube’s watch page. A scene fade handles the visual handoff; check the audio and the full sequence separately before going live.

Choose the right OBS setup for your clips
There are two different controls involved: a media source or playlist determines what OBS plays, while a scene transition determines how the program view changes. OBS documents playlist playback through VLC Video and transitions such as Fade between scenes; it does not document automatic crossfades from one VLC playlist item to the next. OBS Media Sources and the OBS Studio Overview Guide explain these separately.

| Approach | Best for | Advantages | Limits |
|---|---|---|---|
| One VLC Video playlist | Hands-off sequential playback | Playlist, loop, shuffle, and visibility behavior in one source | Documented controls do not specify per-item crossfades; VLC must be installed |
| Separate scenes with Fade | Deliberate visual crossfades between clips | Built-in transition with configurable duration; Studio Mode can prepare the next scene | Requires scene setup, and audio should be checked with the actual clips |
| Track-matte stinger | Custom branded or shaped blends | Animated mask can blend outgoing and incoming scenes | Advanced asset preparation; OBS recommends combining the stinger and matte in one file to avoid separate-file sync issues |
Set up a simple playlist (without automatic crossfades)
- Install OBS Studio and VLC. OBS’s VLC Video source requires VLC. If you use 64-bit OBS, OBS specifies 64-bit VLC. See OBS Media Sources.
- Add a VLC Video source. In the scene where the playlist should play, add a VLC Video source and populate its playlist with your local files.
- Choose playback behavior. Turn shuffle off for a fixed order. Enable looping only if you want the playlist to repeat. Decide what should happen when the source is not visible: the documented default is to stop when not visible and restart when visible.
- Test the sequence. Play the full playlist, including the last-to-first handoff if looping is on. The playlist controls alone are not a documented way to crossfade between items.
Create visual crossfades between specific clips
- Create one scene per clip. In OBS, add a scene for each video you want to transition between, then add that clip as a Media Source in its scene. OBS documents local video formats including MP4, TS, MOV, FLV, MKV, AVI, GIF, and WebM. See OBS Media Sources.
- Set the scene transition. In the Scene Transitions controls, select Fade and set a duration appropriate to the footage. OBS also documents Cut, Swipe, Slide, Fade to color, and Luma Wipe; Fade is the straightforward choice for a conventional crossfade. The transition options and duration are described in the OBS Studio Overview Guide.
- Prepare the incoming scene. Turn on Studio Mode if you want to preview and prepare the next scene before switching it to the live program. When ready, transition to that scene using the configured Fade.
- Keep OBS output live during the handoff. Change the program scene while the OBS stream remains active. A scene change alters the content OBS sends; it does not require ending the YouTube broadcast. Confirm the OBS stream status and YouTube’s preview before starting the full sequence. OBS describes its streaming connection in the OBS Help Portal.
- Review the complete run before relying on it. Check clip timing, aspect ratio, and audio through every transition and through the loop point. The documentation describes controls, not a guarantee of gapless decoding with every file and system combination.
Check audio and avoid promising gapless playback
A Fade scene transition is a visual transition, but the result for audio depends on how the clips and sources are arranged. The reviewed OBS documentation does not provide a universal recipe for crossfading the audio tracks of two video files in every scene configuration. Listen to the actual output while previewing the transition. If continuous music is essential, one practical production option is to prepare a continuous audio bed; do not assume the playlist or scene transition will automatically produce the intended audio blend.

ZowieBox, 4K HDMI NDI Video Encoder/Decoder, HDMI NDI | Native NDI HX3, UVC to HDMI, Pass-Through Video Capture, SRT/RTMP(S)/RTSP, Live Streaming
- Compact but Powerful Design: ZowieBox is smaller than a phone, featuring a tally light and LCD screen for streaming status. Capture console gameplay in up to 4K with zero-lag HDMI passthrough, while the built-in video encoder converts video for IP streaming. The IP stream can also be decoded back to a 4K HDMI signal.
- Standalone Game Streaming: Just plug and play—ZowieBox enables PC-free live gaming without affecting gameplay. As an RTMP hardware encoder and HDMI streamer, it delivers stable streaming directly from your source, making it ideal for gaming, live events, and professional broadcasting.
- NDI|HX3 Converter Technology: ZowieBox converts HDMI signals to NDI|HX3/HX2/HX, functioning as an NDI video encoder, or NDI Video Decoder for flexible IP workflows. Certified NDI technology enables low-latency gameplay streaming through OBS/vMix. Note: Encoder and decoder modes cannot run simultaneously; full NDI signals are not supported.
- UVC to HDMI Conversion: Supporting up to 4K@30fps and 1080p@60fps decoding, ZowieBox enables flexible conversion for webcam and video workflows. As a video decoder and HDMI to IP converter, it expands connectivity options for professional video devices. Note: USB capture card functionality is not currently supported.
- All-around Configuration Options: Control ZowieBox through its web UI on a PC, phone, or tablet. Manage connected PTZ cameras, tally light, video/audio, OSD, work mode, streams, network, and system settings. Support for VISCA over IP encoder workflows enables flexible PTZ control, while the dashboard provides video preview and system status.
Also preview the handoff itself. Neither the playlist setting nor the scene transition documentation promises gapless playback between media files.
Use a track-matte stinger for a designed blend
For a custom animated transition rather than a basic dissolve, OBS supports stinger transitions, including track-matte stingers. The matte can blend the outgoing and incoming scenes; gray mask values allow a degree of fade. OBS notes that it does not support lock-step video decoding for separate track-matte and stinger files and recommends combining the assets in one file. This is an advanced option, not a requirement for a simple Fade. See Track Matte Stinger Transitions.

Keep the YouTube broadcast running through scene changes
The local transition in OBS is separate from YouTube’s ingest protocol. YouTube notes that HLS has higher latency because it sends video in segments rather than as a continuous stream like RTMP; that latency distinction does not mean a scene change in OBS requires ending the broadcast. See YouTube’s HLS setup guidance.

For a continuous stream, check the YouTube preview and OBS stream status before beginning the sequence, then make the scene handoff while output remains active. Changing scenes is not a substitute for checking whether your video and audio are actually playing as intended.

Troubleshoot common transition problems
- The playlist plays but clips cut instead of crossfading: VLC playlist playback and scene transitions are separate controls. Use separate scenes and Fade for deliberate visual transitions.
- VLC Video is unavailable or does not play: Confirm VLC is installed and that its architecture matches OBS; OBS specifically calls for 64-bit VLC with 64-bit OBS.
- A clip stops or restarts after changing scenes: Review the source’s visibility behavior. OBS documents stop-when-not-visible and restart-when-visible behavior, with stop when not visible as the default.
- The picture blends but the audio does not sound continuous: Preview the actual source arrangement and audio. The documentation does not establish one universal audio-crossfade setup.
- The loop point has a pause or jump: Test the last-to-first handoff with the real files. The available documentation does not promise gapless decoding.
- The transition appears late to viewers: Consider whether the broadcast uses HLS. YouTube says HLS has higher latency than RTMP because it sends segments of video; the protocol affects delivery latency, not whether OBS can transition scenes.
