A stinger transition is a short animated video clip that plays over the moment you switch scenes, hiding the cut behind motion, branding, or a splash of color. Instead of a plain fade from your game to your webcam, a stinger sweeps a logo across the screen and swaps the scene at the exact frame the animation covers the whole canvas. It is the single fastest way to make a stream feel produced rather than improvised.
How a stinger actually works
The clip is a normal video file, usually with an alpha channel or a full-screen wipe. OBS plays it on top of both scenes and reveals the new scene at a moment you define, called the transition point. If your animation fully covers the screen at 300 milliseconds into a 600 millisecond clip, you set the transition point to 300 ms so the viewer never sees the raw cut.
Formats that support transparency
Only some formats carry an alpha channel. This matters if part of your animation should stay see-through.
| Format | Alpha channel | Typical file size (2 sec) |
|---|---|---|
| WebM (VP8/VP9) | Yes | 1-4 MB |
| MOV (Apple ProRes 4444) | Yes | 15-40 MB |
| MP4 (H.264) | No | 1-3 MB |
For most creators a WebM file is the sweet spot: it keeps transparency, stays small, and plays back smoothly. Full-screen wipes that never show transparency can use MP4 without any downside.
Adding a stinger step by step
In OBS, open the Scene Transitions box, click the plus button, and choose Stinger. Point it at your video file, then set the transition point in milliseconds (or by frame). Add a matching audio clip if your animation has a whoosh sound, and set audio monitoring so viewers hear it. Test by switching scenes a few times and adjust the transition point until the cut is invisible.
Getting the timing right
Most stingers run 500 to 1200 milliseconds total. Anything longer than about 1.5 seconds starts to feel slow when you switch scenes often. Play the clip frame by frame in a video editor, find the exact frame where the screen is fully covered, and use that timestamp as your transition point.
Hardware that makes stingers easy to fire
Stingers shine when tied to a physical button. A stream controller with 6 to 32 keys lets you assign one key per scene, so the transition plays automatically on press. Without a controller you are alt-tabbing or clicking, which defeats the smooth look. Budget controllers start around $30 to $80, while larger LCD-key models run $120 to $250.
Frequently asked questions
Why does my stinger show a black flash?
A black flash almost always means the transition point is set too early or too late, so the raw cut peeks through before the animation fully covers the canvas. Step through the clip frame by frame, find the fully covered frame, and match the transition point to it in milliseconds.
Do stingers increase CPU usage?
Only slightly, and only during the transition itself. A short WebM decoded a few times per stream is negligible on any modern CPU. If you see stutter, it is more likely a high-bitrate ProRes file; re-export it as WebM to cut the load.
Designing a stinger that fits your brand
A stinger is prime brand real estate because viewers see it dozens of times per stream. Keep it consistent with your overlay: the same accent color, the same logo, the same energy. A frantic, flashing wipe on an otherwise calm cozy stream feels off, while a slow elegant sweep on a hype competitive channel drags. Match the motion to your vibe. Practically, design the animation to fully cover the canvas at some point so the scene swap hides cleanly, and give it a clear direction, such as a left-to-right sweep, so it reads as intentional. If you commission or make several, keep them in a family that shares timing and color so switching between them never feels jarring. And remember accessibility: avoid rapid strobing, which can be uncomfortable for some viewers and may run afoul of platform guidelines on flashing content. A tasteful, on-brand stinger under a second long is one of the highest-impact, lowest-effort touches you can add to a channel.
Bottom line
A stinger transition hides scene cuts behind a branded animation, and setting one up is just a matter of choosing a transparent-friendly format like WebM, dialing in the transition point frame by frame, and ideally firing it from a physical key. Keep it under 1.2 seconds, match the audio, and your channel instantly looks a tier more professional.
