Make videos smoother and create cinematic slow motion with PixelJex, an AI video frame interpolation app, slow motion maker, and FPS enhancer for high-frame-rate video up to 120FPS. PixelJex analyzes motion between frames and generates new intermediate frames to improve motion smoothness. It helps reduce choppy playback, visible stutter, jitter, and low-frame-rate motion in everyday videos, creator clips, gameplay recordings, sports footage, travel videos, action scenes, and older recordings. NEW: AI SLOW-MOTION Create cinematic slow motion from any video. Regular slow motion just stretches each frame, so it looks choppy. PixelJex uses AI frame interpolation to generate brand-new in-between frames, keeping your slow-mo smooth even at 10X. • Slow down video 2X, 4X, 8X, or 10X (0.5x to 0.1x speed) • Smooth slow motion from regular 24, 30, or 60FPS footage • Trim the exact moment and preview the timing before export • Audio options: keep pitch, cinematic pitch drop, or mute • Export at 24 to 60FPS, up to 4K • Perfect for sports, dance, skateboarding, water splashes, pets, and action shots AI VIDEO FRAME INTERPOLATION Turn low-frame-rate footage into smoother high-frame-rate video. PixelJex uses AI frame generation, optical flow, and RIFE-based motion interpolation to create more natural motion than simple frame duplication or frame blending. Use it to: • Make 24FPS or 30FPS videos feel smoother • Convert videos to 60FPS, 90FPS, or 120FPS • Improve gameplay and screen recordings • Smooth sports, dance, travel, and action footage • Reduce stutter in low-frame-rate clips • Refresh old videos with more fluid motion • Create smoother content for social media BOOST VIDEO FPS UP TO 120FPS PixelJex helps you create smoother video from smartphone clips, screen recordings, action camera footage, drone videos, downloaded clips, and family recordings. Choose an FPS boost or interpolation multiplier, let AI generate extra frames, then export a smoother high-frame-rate result. ONE-TAP AI VIDEO SMOOTHER No complex desktop software. No professional editing skills required. How it works: 1. Import your video 2. Choose an FPS boost or interpolation multiplier 3. Let AI generate smooth intermediate frames 4. Export your enhanced high-frame-rate video SMOOTH GIF INTERPOLATION PixelJex also supports AI GIF frame interpolation. Turn choppy animated GIFs into smoother, more fluid loops by generating extra frames with AI. Great for reaction GIFs, memes, animated stickers, emojis, short loops, and social media animations. PRIVATE LOCAL PROCESSING Your videos and GIFs are processed locally on your device. PixelJex does not need to upload your media to the cloud for frame interpolation, helping protect your privacy while keeping your workflow simple. KEY FEATURES • NEW: AI slow motion video maker (2X to 10X) • AI video frame interpolation • AI frame generation for smoother motion • Video FPS enhancer and frame rate booster • Convert video to 60FPS, 90FPS, or 120FPS • RIFE-based AI motion interpolation • Optical flow video smoothing • Reduce video stutter, jitter, and choppy playback • Smooth gameplay, sports, action, travel, and old videos • AI GIF interpolation and GIF FPS enhancement • Local processing for better privacy • Simple one-tap workflow • High-quality video export PixelJex is made for creators, gamers, editors, students, families, and anyone who wants smoother video without complicated editing.
