About NotchTools: Rounded Corners Overlay Generator for Videos
Rounded Corners Overlay Generator is a powerful online tool designed for video editors, content creators, podcasters, and social media creators who want to create modern curved-edge video frames in seconds. Instead of manually creating masks and rounded corners inside complex editing software, this tool helps you instantly generate high-quality PNG overlays with customizable rounded edges and curved frame styles.
The tool is especially useful for creators making Instagram Reels, YouTube Shorts, TikTok videos, podcast clips, cinematic edits, retro-style videos, and aesthetic social media content. It supports multiple aspect ratios including 9:16, 16:9, 1:1, and 4:3, making it suitable for almost every type of content creation workflow.
One of the biggest advantages of this tool is the amount of customization it offers. Users can control frame color, transparency, border radius, border softness, cutout position, curved styles, and frame dimensions without needing advanced editing knowledge. Whether you want sharp rectangle borders, smooth curved corners, or squircle-style overlays, everything can be adjusted with just a few clicks.
This tool saves a huge amount of editing time because creators no longer need to manually draw masks, create feather effects, or export transparent PNG overlays from software like Photoshop or After Effects. Instead, the overlay is generated instantly and can be downloaded directly for use in CapCut, Premiere Pro, Final Cut Pro, DaVinci Resolve, VN Editor, or any video editing software.
For podcast creators, this tool helps create professional podcast frames with soft rounded borders that look modern and premium. For reel creators, it helps produce viral aesthetic edits with smooth rounded corners similar to trending social media videos. It is also useful for creating old TV-style frames, cinematic matte overlays, gaming stream layouts, and custom content presentation frames.
The border softness feature adds a feather-like smooth edge effect, making overlays look more natural and polished instead of harsh and artificial. The transparency controls also help creators build semi-transparent overlays for layered visual styles and modern UI-inspired edits.
Overall, this tool is a simple yet highly effective solution for creators who want professional-looking curved video frames without wasting time on manual editing workflows.
