Hey there!

That glowing line effect definitely looks cool for TikTok edits. While CapCut does not have a direct "neon line" feature with all the customization you see there right out of the box, you can achieve a similar effect using layers and some creative adjustments.

Here's a general idea of how you might be able to create something similar in CapCut:

1. Draw or Import a Line: You could either try to draw a line using CapCut's drawing tools or, for more control, create a line with a transparent background in a separate graphic design app and import it as an overlay.
2. Duplicate and Blur: Duplicate the line layer. Apply a blur effect to the duplicated layer. This will create the "glow" around the main line.
3. Adjust Colors: Change the color of both the main line and the blurred layer to your desired neon hue.
4. Layer Order and Opacity: Make sure the blurred layer is underneath the sharp line layer. Adjust the opacity of the blurred layer to control the intensity of the glow.
5. Animation: To make it dynamic like in the video, you could animate the position, scale, or even the opacity of the line over time using CapCut's keyframes.

Here os how you can create that same look:

• Option 1: Use a Neon Border Overlay (Easiest Method)
  • Import your video.
  • Go to “Overlay” > “Add Overlay”, then use:
    • A pre-made neon border PNG (you can find these online or I can help make one for you).
    • Or, search in CapCut’s “Effects” under “Frame” or “Neon”.
  • Resize and position it to fit your frame.
  • Adjust blend mode, glow, or opacity if needed.
• Option 2: Manual Line Drawing (For Custom Shapes)
  • If you want a custom neon line exactly like in the screenshot:
    • Use “Draw” tool (if available) or use a neon line PNG.
    • Position it manually to mimic the border line.
    • You can animate it with keyframes to follow any motion or just stay static.
    • Add “Glow” or “Shadow” effects to give that neon look.
• You can also add a "Neon" animation or effect under "Effects" > "Video Effects" > "Neon" for more glow around the subject or frame.

Here is a transparent neon border PNG for TikTok-style clips:

It might take some experimentation with the blur settings, colors, and opacity to get the exact look you're after. You could also explore the "stroke" or "outline" features for shapes that you could then blur.
