Video Retouching Tool

Purpose & User Intent: This tool provides a focused video retouching pipeline that enhances foreground subjects and overall footage without editing audio. Target users are content creators, editors, social media teams, and mobile video producers who need fast, high-quality enhancements on Android or desktop. Typical use: post-capture correction for skin smoothing, color grading, stabilization, and noise reduction to improve consistency across clips in a batch or single video.
Core Logic & Features: The tool implements a modular processing pipeline. Required features: ingest source video; configure target resolution and output format; run processing; export result. Optional/advanced features: stabilization with motion compensation, AI-based skin smoothing, color grading via LUTs, noise reduction strength, and batch processing. It uses a GPU-accelerated encoding path when available and falls back to CPU otherwise. Core differentiators include mobile-optimized performance, non-destructive preview, and export-preserve options.
Inputs & Outputs: Inputs include video_file (path or blob; mp4/mov), target_resolution (720p/1080p/4K), bitrate (Mbps, optional), output_format (mp4/mov), stabilize (bool), color_grade (string/LUT), retouch_strength (0-100), apply_noise_reduction (bool), audio_preserve (bool). Outputs include processed_video (file), duration_seconds, final_bitrate, resolution, format.
Algorithms & Calculations: The processing chain decodes frames, applies color corrections and LUTs, runs stabilization using motion estimation, applies retouching filters, performs denoising and optional upscaling, then encodes with selected codec/bitrate. Recommended bitrate ranges: 720p 3–6 Mbps; 1080p 8–12 Mbps; 4K 25–60 Mbps. The approach prioritizes preserving natural skin tones and motion fidelity while minimizing artifacts.
Error & Edge Cases: Handles unsupported formats by failing gracefully with clear validation results, missing inputs by using safe defaults, corrupted frames by skipping or re-trying frames, insufficient disk space by aborting with precise error codes, and GPU encoding fallback messaging.
Industry/Region & Localization: Aligns with modern video standards: 24/30/60 fps, common codecs H.264/HEVC, supported timecodes and frame rates; output units in Mbps and pixels. Assumptions: audio remains unedited unless explicitly requested. Exclusions: no audio editing or multi-camera stitching.
