Fast & Slow Motion Video Maker

Create smooth slow motion and timelapse videos in seconds

Fast & Slow Motion Video Maker focuses on one thing and does it well: changing the speed of your videos with minimal fuss. Instead of overwhelming you with complex timelines and layers, it offers a straightforward way to slow down or speed up any clip you already have, or one you record on the spot with your camera.

The interface is clean and self-explanatory. After picking a video, you simply choose how fast or slow you want it to play, from a dramatic 10% of the original speed up to a brisk 200%. This makes it equally useful for cinematic slow-motion shots, playful time-lapses, or quick highlights of longer recordings such as events or everyday moments.

Because the app is built on the FFmpeg media library, processing is generally efficient and stable. The quality of the slow motion depends heavily on the frame rate of your original footage: videos shot at higher frame rates (like 60 fps or more) will produce much smoother, more professional-looking slow motion, while standard 30 fps clips may look a bit choppy when pushed to extreme slow speeds. This is expected behavior for any speed-editing tool, but it is worth keeping in mind.

Fast & Slow Motion Video Maker is deliberately simple, which is both its strength and its limitation. You won’t find multi-track editing, filters, or advanced color correction here, but if your primary goal is just to control playback speed quickly and clearly, it excels. It’s a practical choice for users who want to enhance their videos with slow-motion or fast-motion effects without diving into complex video-editing software.
