How accurate is the AI captioning?

In a quiet room with a clear microphone, our engine is about 95% accurate. We always provide a built-in text editor so you can fix any misheard words or brand names.

Can I choose the font and color?

Yes! We offer a range of standard fonts and a color picker for both the text and the background highlight.

Does it support multiple languages?

Currently, we are optimized for English. Support for Spanish, French, German, and Portuguese is coming in the next update.

Will the video quality decrease?

No. We use high-quality H.264 encoding to 'burn' the subtitles, ensuring your video stays sharp and clear even after the text is added.

Yes. 100% free with no watermarks. We believe creators shouldn't have to pay to make their content accessible.

Why Subtitles are the Secret to Social Media Growth

Subtitles do more than just help the hearing impaired; they are a critical tool for engagement and SEO:

1. The 'Quiet' Viewer: Most people watch videos in public, at work, or in bed while their partner is sleeping. Without subtitles, they will simply swipe past your content.

2. Increased Retention: Reading along while listening increases information retention and keeps viewers focused on your screen for longer, which signals 'High Quality' to platform algorithms (TikTok/Instagram).

3. Language Accessibility: Millions of viewers may speak English as a second language. Text provides the missing context that helps them understand your accent or fast-paced delivery.

4. SEO Benefits: When you upload an SRT file to YouTube or LinkedIn, those words are indexed by search engines, allowing your video to show up for thousands of new keywords.

Reelic specializes in Burned-in Subtitles because we know most of our users are creators building for mobile platforms where you need maximum visual impact from second one.

The Reelic Local-AI Paradigm: Privacy for Your Voice

Your voice is one of your most personal assets. Cloud-based AI captioning tools often store your audio to 'improve their models', effectively training their AI on your voice without your explicit consent.

Our Privacy Promise: Reelic runs its analysis in your browser. We don't send your voice to an external API. We don't save your scripts. Whatever happens in your Reelic tab, stays in your Reelic tab. Professional security for the modern creator.

Caption Styling Tips for Maximum Impact

When burning subtitles into your video, follow these professional design rules:

- High Contrast: Use white text on a black semi-transparent background, or thick black outlines on white text. If your captions are hard to read, they are useless.

- The 'Safe Zone' Rule: Don't place your captions too low. On TikTok and Instagram, the 'Description' and 'Like' buttons will cover them up. Aim for the middle-bottom area (about 20-30% from the bottom).

- Minimal Lines: Don't show more than two lines of text at once. It overwhelms the viewer. One line at a time is the 'Short Form' gold standard.

Workflows: From Subtitles to Global Reach

A subtitle is just the beginning. Use the Reelic ecosystem to maximize your video's potential:

- Video Background Remover: Clean up your talking-head background before adding captions for a cleaner look.

- Audio Noise Remover: Ensure your voice is crystal clear so our captioning engine (and your viewers) can understand you perfectly.

- Video Format Converter: If your camera output a weird format, convert it to MP4 first for the best captioning performance.
