"hey guys check out mywebsite.com for iphone tips"

• Brand names get lowercased ("iphone" instead of "iPhone")
• URLs are unreadable ("mywebsite.com" - no capitals)
• No control over style
• Misspells technical terms and product names
• Stuck with whatever TikTok decides

✅ With OUR Tool:

"Hey guys check out MyWebsite.COM for iPhone tips"

• Perfect capitalization - "iPhone" stays "iPhone"
• Readable URLs - "MyWebsite.COM" is clear and branded
• FULL CAPS for emphasis - make words POP
• MiXeD CaSe for style - express your brand personality
• YOU control every letter

🎯 The Two Game-Changing Features

1️⃣ TRANSPARENT OVERLAY EXPORT (The Main Feature!)

Unlike other tools that burn captions directly into your video, this generates a separate transparent video file with ONLY the captions and a black background.

Why this is HUGE:

• 🎨 Full editing control - Import into Premiere Pro, DaVinci Resolve, Final Cut, CapCut, etc.
• 📐 Position anywhere - Top, middle, bottom, side - wherever you want
• 🔄 Scale & adjust - Make captions bigger or smaller
• 🎬 Multi-layer - Combine with other effects, graphics, and animations
• ♻️ Reusable - Use the same caption overlay on different video edits
• 🎨 Professional workflow - Fits into YOUR editing process, not forced into a template

Perfect for:

• Professional video editors
• Content creators who edit in Premiere/Final Cut
• Anyone who wants maximum creative control
• Multi-platform content (different crops need different positioning)

2️⃣ CUSTOM SCRIPT WITH PERFECT CAPITALIZATION

Provide your own script, and the AI will sync it to your speech with PERFECT timing while keeping your EXACT capitalization.

Real-World Examples:

Brand Names:

• ✅ "iPhone" not "iphone"
• ✅ "TikTok" not "tiktok"
• ✅ "YouTube" not "youtube"
• ✅ "ChatGPT" not "chatgpt"

Websites & URLs:

• ✅ "MyBrand.COM" - clear and readable
• ✅ "ProductName.io" - proper branding
• ✅ "SALE.website" - stands out

Stylistic Choices:

• ✅ "LET'S GO!!!" - full caps for hype moments
• ✅ "WhAt ArE yOu DoInG" - spongebob meme style
• ✅ "WATCH THIS" - emphasis on key phrases
• ✅ "Subscribe to @YourChannel" - social handles stay formatted

How it works:

1. Upload your audio/video
2. Provide your script with YOUR exact capitalization
3. AI syncs your text to the spoken words with millisecond precision
4. Get back animated captions with PERFECT capitalization matching YOUR style

---

🚀 How to Use

Step 1: Upload Your Content

• Upload your video or audio file to a public URL (Dropbox, Google Drive, AWS S3, etc.)
• Supported formats: MP4, MOV, WebM, MKV (video) or MP3, WAV, M4A, FLAC (audio)

Step 2: Write Your Script (RECOMMENDED!)

This is where the magic happens!

• Write out exactly what you said in the video
• Use EXACT capitalization for brand names, URLs, and style:
  • "Check out MyBrand.COM" ✅
  • "Download the iPhone app" ✅
  • "This is INSANE!" ✅
  • "WoW tHiS iS cRaZy" ✅ (yes, even meme case works!)
• The AI will sync your script to your speech perfectly

Don't have a script? No problem! It will auto-transcribe, but you'll get generic lowercase text like TikTok.

Step 3: Choose Output Type

IMPORTANT: Select "Transparent Overlay" (the default and recommended option!)

• You'll get a video file with captions on a black background
• Import this into your video editor (Premiere, DaVinci, CapCut, etc.)
• Layer it over your original video
• Position, scale, and adjust as needed

Alternative: "Captioned Video" burns captions directly onto your video (quick but less control)

Step 4: Customize the Look (Optional)

Make it match your brand:

• Colors (text, highlight, outline, shadow)
• Fonts and sizes
• Position on screen
• Effects and animations

Step 5: Download & Import

1. Download your transparent caption overlay
2. Import into your video editor
3. Place it over your original video
4. Adjust positioning and scaling
5. Export your final video with perfect captions!

❓ FAQ

Q: What's the difference between this and TikTok's auto-captions? A: TikTok lowercases everything and you can't control the output. We give you FULL control over capitalization (keep "iPhone" as "iPhone", not "iphone") AND you get a transparent overlay file you can edit professionally.

Q: What's a "transparent overlay" and why do I want it? A: It's a video file with just the captions on a black background. You import it into your video editor, layer it over your original video, and you can position/scale/adjust it however you want. Way more professional than burned-in captions!

Q: How do I use the transparent overlay in my editor? A: Import both your original video and the transparent overlay. Place the overlay on a track above your video. In Premiere/Final Cut/DaVinci, use a "Screen" or "Lighten" blend mode (or just leave it normal - the black disappears). Position and scale as needed!

Q: Do I HAVE to provide a custom script? A: No! If you don't provide a script, it will auto-transcribe your speech like TikTok does. But then you'll get generic lowercase text and miss the main benefit of this tool - perfect capitalization control.

Q: Will it mess up the timing if I change the capitalization? A: Nope! The AI syncs YOUR script to the speech timing. As long as the words match what you said, the capitalization can be anything you want.

Q: Can I use this for branding and business content? A: Absolutely! That's exactly what it's designed for. Keep your brand name, product names, and URLs formatted perfectly.

Q: What video editors work with the transparent overlay? A: Any editor that supports video layers: Premiere Pro, DaVinci Resolve, Final Cut Pro, CapCut, Filmora, Vegas Pro, even mobile apps like InShot and VN.

Q: How long does it take? A: Usually 2-5 minutes depending on video length. A 1-minute video processes in about 2-3 minutes.

Q: Can I customize colors and fonts? A: Yes! Full control over colors, fonts, sizes, positioning, outlines, shadows - everything.
