<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=1920, height=1080">
    <title>Countdown Timer</title>
    <style>
        body {
            margin: 0;
            padding: 0;
            width: 1920px;
            height: 1080px;
            background: transparent;
            display: flex;
            justify-content: center;
            align-items: center;
            font-family: 'Arial Black', sans-serif;
            color: white;
            overflow: hidden;
        }

        #countdown {
            font-size: 200px;
            text-align: center;
            text-shadow: 0 0 40px rgba(255, 255, 255, 0.8),
                         0 4px 20px rgba(0, 0, 0, 0.9);
            animation: pulse 1s ease-in-out infinite;
        }

        @keyframes pulse {
            0%, 100% { transform: scale(1); }
            50% { transform: scale(1.05); }
        }

        .label {
            font-size: 48px;
            margin-bottom: 20px;
            text-shadow: 0 2px 10px rgba(0, 0, 0, 0.8);
        }
    </style>
</head>
<body>
    <div style="text-align: center;">
        <div class="label">Stream Starting In:</div>
        <div id="countdown">3:00</div>
    </div>

    <script>
        // Set countdown duration (in seconds)
        let totalSeconds = 180; // 3 minutes

        function updateCountdown() {
            if (totalSeconds <= 0) {
                document.getElementById('countdown').textContent = 'GO!';
                return;
            }

            const minutes = Math.floor(totalSeconds / 60);
            const seconds = totalSeconds % 60;
            const display = minutes + ':' + (seconds < 10 ? '0' : '') + seconds;

            document.getElementById('countdown').textContent = display;
            totalSeconds--;
        }

        // Update immediately
        updateCountdown();

        // Update every second
        setInterval(updateCountdown, 1000);
    </script>
</body>
</html>

2. Add Browser Source to OBS

Add Source: Sources → + → Browser Name: "HTML Countdown"
Configure: ✅ Local file: Browse to countdown.html Width: 1920 Height: 1080 FPS: 30 (saves CPU vs 60) ✅ Shutdown source when not visible (performance) ✅ Refresh browser when scene becomes active
Custom CSS (Optional):
Add custom styling in "Custom CSS" field
Override colors, fonts, animations

3. Customize for Your Brand

Change Colors:

/* In the <style> section */
body {
    color: #9B59B6; /* Purple text */
}

#countdown {
    text-shadow: 0 0 40px rgba(155, 89, 182, 0.8); /* Purple glow */
}

Change Duration:

// In the <script> section
let totalSeconds = 300; // 5 minutes instead of 3

Add Background:

body {
    background: linear-gradient(135deg, #667eea 0%, #764ba2 100%);
    /* Or background: url('background.jpg'); */
}

Advanced OBS Countdown Techniques

Multiple Countdown Durations

Strategy: Create scenes for different countdown lengths

Scene Setup:

"Starting Soon - 2 Min" (quick start)
"Starting Soon - 5 Min" (standard)
"Starting Soon - 10 Min" (event stream)
"BRB - 3 Min" (bathroom break)
"BRB - 10 Min" (meal break)
"Stream Ending - 5 Min" (outro countdown)

Hotkey Assignment:

F1: Starting Soon 5 Min
F2: BRB 3 Min
F3: Stream Ending 5 Min

Workflow: Press hotkey → automatic countdown starts

Auto-Switching After Countdown

Goal: Countdown ends → automatically switch to gaming scene

Setup (Requires Advanced Scene Switcher Plugin):

1. Install Advanced Scene Switcher: - OBS → Tools → Browse Plugins - Search "Advanced Scene Switcher" - Install and restart OBS

2. Configure Auto-Switch: ``` Advanced Scene Switcher → Media tab

If: Media source "Countdown Timer" State: Playback ended Then: Switch to scene "Gaming" ```

3. Test: - Activate "Starting Soon" scene - Countdown plays - At 00:00, scene automatically switches to gaming

Benefit: Hands-free streaming start (press one button, stream begins automatically after countdown)

Dynamic Countdown Updates (Browser Source)

Problem: Break takes longer than expected, need to extend countdown

Solution: URL parameters in HTML

countdown.html (Modified):

// Get duration from URL parameter
const urlParams = new URLSearchParams(window.location.search);
let totalSeconds = parseInt(urlParams.get('duration')) || 180; // Default 3 min

// Rest of countdown code...

OBS Browser Source URLs:

Short: file:///C:/OBS/Timers/countdown.html?duration=120
Standard: file:///C:/OBS/Timers/countdown.html?duration=300
Long: file:///C:/OBS/Timers/countdown.html?duration=600

Benefit: One HTML file, infinite durations via URL

Countdown with Progress Bar

Visual Enhancement: Add progress bar below timer

HTML Addition:

<div id="progress-container" style="width: 600px; height: 20px; background: rgba(255,255,255,0.2); border-radius: 10px; overflow: hidden; margin-top: 20px;">
    <div id="progress-bar" style="height: 100%; background: linear-gradient(90deg, #667eea, #764ba2); transition: width 1s linear;"></div>
</div>

JavaScript Addition:

const startSeconds = totalSeconds;

function updateCountdown() {
    // ... existing countdown code ...

    // Update progress bar
    const progress = ((startSeconds - totalSeconds) / startSeconds) * 100;
    document.getElementById('progress-bar').style.width = progress + '%';
}

Result: Visual countdown + numeric display for enhanced clarity

Troubleshooting Common Issues

Issue: Countdown Not Starting

Possible Causes & Solutions:

1. Media Source Not Set to Restart:

Right-click Media Source → Properties
✅ Restart playback when source becomes active

2. Scene Not Activating Source: - Click scene directly in Scenes panel - Don't just preview, must be active

3. File Path Broken (Browser Source): - Verify HTML file exists at specified path - Check for typos in file path

4. Snaz Timer Not Running: - Snaz.exe must be running in background - Click "Start Timer" in Snaz interface

Issue: Countdown Lags or Stutters

Causes & Solutions:

1. Browser Source FPS Too High:

Lower FPS from 60 to 30:
Browser Source → Properties → FPS: 30

2. Heavy JavaScript Animations: - Simplify animations in HTML - Remove complex effects - Test CPU usage (Task Manager)

3. Multiple Browser Sources: - Close unnecessary browser sources - Use "Shutdown when not visible" option

4. Low-End PC: - Switch to pre-rendered video (zero CPU impact) - Or use Snaz (text-based, minimal resource use)

Issue: Countdown Loops Instead of Stopping

Solution:

Media Source:

Properties → ❌ Uncheck "Loop"

Browser Source HTML:

// Ensure clearInterval at countdown end
if (totalSeconds <= 0) {
    document.getElementById('countdown').textContent = 'GO!';
    clearInterval(countdownInterval); // Stop the interval
    return;
}

Issue: Timer Not Visible on Stream

Possible Causes:

1. Source Below Other Layers: - Reorder in Sources list - Drag timer source to top

2. Source Outside Canvas: - Right-click → Transform → Fit to screen - Or manually reposition

3. Transparent Background Not Working:

Browser Source HTML:
body { background: transparent; } /* Not background: none; */

4. Color Blending with Background: - Change timer text color - Add drop shadow or outline

Issue: Audio Desynced from Timer

Cause: Audio longer/shorter than video countdown

Solution:

Remux Video: 1. Use FFmpeg (free tool): ffmpeg -i countdown.mp4 -c copy -shortest countdown_fixed.mp4 2. Replace in OBS

Or Regenerate: - Create new countdown at CreateTimer - Ensure audio duration matches video

Performance Optimization

OBS Settings for Best Performance

Video Settings:

Output (Scaled) Resolution: 1280x720
(1080p if GPU can handle)

4. Test Before Going Live: - Run countdown scene for full duration - Monitor CPU usage (OBS Stats panel) - Target: <70% CPU usage

Mobile Streaming with OBS

Countdown Timers on Mobile OBS Apps

Streamlabs Mobile (iOS/Android): - Built-in countdown widget - Limited customization - Quick setup (5 minutes)

Prism Live Studio: - Countdown template available - Mobile-friendly interface

Limitations: - Lower quality than desktop - Fewer customization options - Pre-rendered video best option (generate on desktop, transfer to phone)

Workflow: 1. Generate countdown at CreateTimer (desktop) 2. Transfer MP4 to phone (Google Drive/Dropbox) 3. Import into mobile OBS app 4. Add as media source

Platform-Specific Considerations

Twitch

Recommended Countdown Durations: - Starting Soon: 2-5 minutes - BRB: 3-10 minutes (avoid longer, Twitch may penalize excessive AFK) - Stream Ending: 5 minutes (maximize follow call-to-action)

Resolution: 720p or 1080p (Twitch compresses anyway)

YouTube

Recommended: - Starting Soon: 5-10 minutes (longer acceptable) - Use YouTube's built-in premiere countdown for video premieres - OBS countdown for livestreams

Facebook Gaming

Recommended: - Starting Soon: 3-5 minutes - Similar to Twitch guidelines
