VidPair vs CutStyle

VidPair is an app that lets you place two videos side by side and compare them at the same time. Use slow motion, mirroring, rotation, and time skipping to closely examine every detail. You can leave notes as timestamps and restore them later all at once for easy review. You can also export the two compared videos as a single video file, making it easy to save practice records and share your progress. Perfect for analyzing dance and sports form or reviewing lessons. Main Features • Dual video playback: Play two videos side by side or vertically • Synchronized playback: Start both videos at the same time for smooth comparison • Speed control: Slow motion and fast playback for detailed checks • Display adjustments: Mirroring and rotation supported • Time skip: Customize skip intervals for forward and backward playback • Audio control: Mute each video independently • Notes with timestamps: Record key points and jump to them with one tap • Favorites: Restore titles and notes together • History list: Quickly revisit past comparisons • Video export (Download) Export two videos as a single video in a vertical stacked layout Choose audio source (top video / bottom video / no audio) Export from the current playback position Save directly to the Photos app Recommended for • Dancers who want to compare movements and refine their form • Anyone who wants to visualize progress and track improvement • Athletes who want to objectively analyze posture and technique • Users who want to save comparison results as videos for review Simply placing yesterday and today side by side makes your progress instantly visible.

CutStyle is the ultimate offline video analysis and auto-segmentation tool built specifically for canoe freestyle paddlers, coaches, and videographers. Say goodbye to hours of manually scrubbing through long training session videos just to find and cut individual rides. CutStyle uses state-of-the-art local AI to automatically detect, slice, and group your wave and hole runs directly on your iPhone. Key Features: 1. AI-Powered Ride Auto-Detection & Lossless Slicing • Automatically scans long video files and identifies the exact start and end times of every freestyle ride with millisecond precision. • Slices the detected runs instantly using hardware-accelerated lossless extraction, saving each clip in milliseconds without any quality loss. 2. Standalone On-Device Local AI (No Cloud Required) • Utilizes Apple’s CoreML and Vision frameworks to run a high-performance YOLO11 object detection model entirely offline on your device’s Neural Engine. • Tracks and isolates the main paddler closest to the center of the screen, ignoring background spectators and eddy queues. 3. Vibrant Gear Color Extraction & Smart Grouping • Automatically crops three target zones for color matching: Helmet (HM), Life Jacket (LJ), and Boat Hull. • Employs advanced HSV-based water/foam filters to capture true gear colors even during water submersions. • Clusters rides by paddler using CIEDE2000 ΔE color difference algorithms, isolating distinct boat hull colors (green, white, blue, etc.) with a strict constraint gate. 4. Interactive Manual Organizer & Sensitivity Control • Features a real-time Clustering Sensitivity slider to dynamically adjust groups from strict (split) to loose (merge). • Drag-and-drop ride thumbnails between paddler cards to quickly refine groupings. • Double-tap paddler names to customize output folder names. • Drag failed runs or empty waves to the "Trash Box" card to exclude them from the final export. Your Trash Box choices are fully preserved even if you adjust the sensitivity slider. 5. Premium Gallery & Document Export • Excludes the Trash Box and lets you select exactly which paddlers to export. • Creates structured directories for each paddler inside your device's Documents or Photo Library. • Copies the trimmed ride video (.mp4) and its corresponding thumbnail image (.jpg) side-by-side for instant visual cataloging. 6. Built-in Loop Player • Tap any ride thumbnail to open the preview modal. Check your clips instantly with looping video playback. 7. 100% Offline & Private • Your videos never leave your device. All machine learning, frame decoding, and video cutting are executed entirely locally in a secure sandbox. No internet connection or account registration is required to analyze your videos. Designed for the Freestyle Community: Whether you are a competitive athlete tracking your progress, a coach managing a team of paddlers with different gear colors, or a videographer looking to distribute clips to athletes quickly, CutStyle simplifies your workflow. Turn long, tedious video files into a neatly organized library of clips in seconds.
