Video Merge Tool

Purpose & User Intent: This tool provides a straightforward way to merge multiple video clips into a single deliverable. Target users include content editors, marketers, educators, and social creators who must compose cohesive narratives from disparate footage. Common scenarios include assembling product demonstrations from several shots, compiling lectures into a single resource, and creating highlight reels from event footage. Core Logic & Features: It supports sequential concatenation and overlay-style merges, preserves or re-encodes inputs to a chosen output format, and exports a final file suitable for web distribution. It validates formats and manages simple timeline alignment.
Inputs & Outputs: Inputs include video_sources (array of file references or URLs), merge_mode (sequence|overlay), timeline_positions (array of seconds, optional), output_format (mp4, mov), and resolution and frame_rate. Outputs include merged_video (file) with a defined duration and file size. Algorithms & Calculations: Timeline construction uses start times, duration, and mode selection. In sequence mode, clips are concatenated; in overlay mode, frames are blended with alpha compositing where supported, with conflicts resolved by priority. The tool preserves aspect ratio where possible and performs necessary transcoding to the chosen format.
Error & Edge Cases; Industry/Region & Localization; Assumptions & Exclusions: Missing inputs, unreadable sources, or incompatible formats trigger input-level errors and require re-upload or transcoding. Very large files or long timelines may exceed memory constraints, in which case chunked processing or size limits apply. Supports common frame rates (24/30/60) and aspect ratios (16:9, 4:3); outputs are tuned for web distribution and cross-platform compatibility. Assumes you own rights to all inputs; excludes advanced color grading or audio mastering, 3D video, or multi-camera synchronization beyond basic timeline alignment.
