## Development Plan: Video Converter

This document outlines the development plan for the Video Converter project, aiming to create a standalone Python tool for converting video files into DaVinci Resolve compatible formats.

### Overall Goal
Develop a user-friendly, standalone Python tool to convert video files into formats compatible with Davinci Resolve (Free edition on Linux) to improve editing workflows for content creators.

### Completed Features

*   **Core Conversion Logic:** Implemented video conversion using `ffmpeg` with `dnxhd` codec and `pcm_s16le` audio, outputting to `.mov` container.
*   **Quality Profile Picker:** Added `--quality` argument (low, medium, high, archive) to control `dnxhd` profiles.
*   **Filename Fail-safe:** Implemented logic to append `_1`, `_2`, etc., to output filenames if a file with the same name already exists.
*   **`yt-dlp` Integration:** Added `--url` argument to download videos from YouTube (and other supported sites) using `yt-dlp` before conversion.
*   **PyInstaller Bundling:** Successfully bundled the application into a standalone executable for Linux.
*   **Robust Download Path Handling:** Ensured `yt-dlp` downloads directly to the user-specified output directory (or current working directory if not specified), resolving `os.path.exists()` issues within the PyInstaller environment.
*   **Basic Error Handling & Logging:** Suppressed verbose `yt-dlp` output and redirected `ffmpeg` output to `ffmpeg_output.log` for detailed error inspection.

### Current Priorities (Next Steps)

1.  **Implement GUI:** Develop a graphical user interface for easier interaction, including file selection, quality profile choice, and URL input. (High Priority)
2.  **Implement Browser Cookies for YouTube Authorization:** Revisit and implement `--cookies-from-browser` functionality for `yt-dlp` to handle age-restricted or private YouTube videos. (Deferred, now higher priority)
3.  **Refine Error Handling/Logging:** Implement more user-friendly error messages, potentially displaying the last few lines of the log file directly in the console upon failure, and providing clear instructions to check the full log.

### Future Considerations

*   **Batch Processing:** Allow conversion of multiple files or URLs in a single run.
*   **Configuration File:** Implement a configuration file (e.g., YAML, JSON) for persistent settings.
*   **Progress Bar:** Integrate a progress bar for both download and conversion processes.
*   **Cross-Platform Compatibility:** Explore bundling for Windows and macOS. (Lowest priority)
*   **Advanced `ffmpeg` Options:** Expose more `ffmpeg` options (e.g., bitrate, resolution scaling) for advanced users.
*   **Metadata Preservation:** Option to preserve or transfer metadata from the original file.

### Known Issues / Limitations

*   DaVinci Resolve Free on Linux has limitations with certain audio codecs (e.g., AAC) and 4K output/encoding (requires Studio version).
*   `ffmpeg-full` AUR package is required for `dnxhd` support on Arch-based systems.
