What is a neon caption effect?
A neon caption effect adds vibrant, glowing text to your video that looks like a real neon sign. Each word pulses with electric light — a bright white core fading into a soft colored glow halo — in vivid shades of cyan, electric blue, and violet.
Unlike simple text overlays, AuraCaptions renders the neon effect frame by frame directly onto your video. That means the glow is physically burned into the file — it plays on any device, any platform, without any extra apps or layers.

Frequently asked questions
Is the neon caption effect really free?
Yes. AuraCaptions is free to use with no watermark. You get 300 seconds of video processing free. No credit card required.
How does the neon glow work technically?
AuraCaptions uses a Node.js canvas rendering pipeline to draw the neon effect frame by frame. Each frame is composited onto your video using FFmpeg, so the glow is literally baked into the pixels — not a CSS overlay or player plugin.
Can I customize the neon colors?
Yes. You can choose the tube color (the bright core) and halo color (the surrounding glow) to match your brand or aesthetic.
Does it work with my language?
AuraCaptions uses Deepgram for transcription, which supports dozens of languages including English, Spanish, French, German, Japanese, and more.
