- TimelinePanel: Playblast button opens modal with output dir (native folder picker via IFileOpenDialog), custom resolution (HD/FHD/4K presets), frame range, and movie export toggle - UsdSceneRenderer: CaptureFrame() reads pixels from resolved MSAA FBO; Render() stores last dimensions for off-screen re-render at capture res - MovieEncoder: streams RGBA frames directly into MP4 using libavcodec/ libswscale (H.264, tries libx264 → nvenc → qsv → amf → openh264) - Application: CapturePlayblastFrame() re-renders at capture resolution each frame; opens/writes/closes MovieEncoder inline with the render loop - FileDialog: BrowseFolder() using Vista-style IFileOpenDialog (COM) - CMake: FindFFmpeg.cmake locates prebuilt BtbN GPL shared package in third_party/ffmpeg; links and copies DLLs for main and test targets Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
