WPF to MP4 Converter

About This Tool

This tool accepts a WPF project folder, a compiled assembly, or a set of XAML frames representing an animation sequence and renders it into a self-contained MP4 video. It targets developers, UI/UX designers, and QA engineers who need repeatable visual demos or automated test captures. Conceptually, the tool treats each frame as a render pass, applies WPF effects, transforms, and storyboard-driven changes, and encodes the sequence into time-based media without manual recording. The approach preserves animation timing, color fidelity, and resource usage by integrating a render backend that mirrors the runtime environment while exporting a portable video.

Inputs and processing: the tool accepts input_path (WPF project folder or XAML asset set), start_time_sec, end_time_sec, width_px, height_px, frame_rate, bitrate_kbps, include_audio, audio_source, and output_path. It loads resources, resolves theme dictionaries, and renders frames at the specified frequency. The backend then encodes frames using an established codec to MP4, optionally embedding an audio track. Example: input_path='C:/proj/ui', 1920x1080, 30fps, 4000 kbps, output_path='C:/videos/demo.mp4'.

Who benefits: software teams delivering design reviews, demos, or automated checks gain reproducible visuals, reduced setup time, and consistent playback across environments. Unique value lies in aligning WPF visuals with final media output, supporting DPI awareness, resource management, and integration with build pipelines. Outputs include the MP4 file, a log file, and optional metadata; errors are surfaced via logs with actionable guidance. Edge cases include missing fonts, dynamic resources loaded at runtime, and large scenes that exceed memory constraints; the tool can fall back to a lower resolution or chunked rendering.
