FrameShift 1.16.0

Prepared for later publication.

• Create Subtitle File — internal subtitle model. Subtitle generation now keeps a shared SubtitleProject / SubtitleSegment / SubtitleWord model with preserved word timings from the worker.
• Create Subtitle File — new export targets. The same subtitle model now feeds Standard SRT, Advanced ASS Subtitle, and FrameShift Customization Project (.frameshift-subtitles.json) without changing the default SRT behavior.
• Create Subtitle File — versioned project format. Added full SubtitleProject serialization in the FrameShift project format (frameshift-subtitle-project, v1) for later editing or re-export.
• Create Subtitle File — ASS presets. Advanced ASS Subtitle now supports Classic, Word Highlight, and Progressive Reveal. Dynamic presets use reliable word timings and automatically fall back to Classic when a segment alignment is not reliable.
• Create Subtitle File — refined display start. Dynamic ASS exports now keep the Whisper word timings as source of truth while allowing a conservative delayed cue display start when local audio onset clearly happens later. SRT, ASS, the serialized project, and Add Subtitles to Video all reuse the same shared display start.
• Create Subtitle File — Word Highlight semantics. No subtitle is shown during the preceding silence. At the refined start of the first spoken word, the full sentence appears immediately and the current word is highlighted; Progressive Reveal remains progressive.
• Create Subtitle File — UI / CLI wiring. The picker keeps Standard SRT as default, shows the ASS preset choice only when Advanced ASS Subtitle is selected, and the CLI now supports --subtitles-format plus --subtitles-ass-preset / --ass-preset.
• Add Subtitles to Video — selectable track lot. Added add-subtitles-video as a product action that muxes an external .srt subtitle file into a video as a selectable track. MKV keeps a native subrip subtitle track; MP4/MOV/M4V keep their container with mov_text when existing streams stay compatible; otherwise the action falls back to MKV to preserve streams more cleanly. The normal path copies existing video/audio streams without re-encoding, uses adjacent unique naming, and removes partial outputs on failure or cancellation. Minimal launcher wiring accepts --subtitle-file / --subtitle-path / --srt-file or opens a simple file picker when the option is missing.
• Add Subtitles to Video — burn lot. add-subtitles-video now also supports Burn Subtitles Into Video via --subtitle-mode burn. It accepts .srt, .ass, and .frameshift-subtitles.json, converts .srt / FrameShift projects to a temporary resolution-aware .ass, burns through FFmpeg, copies audio when compatible with the output container, and removes both partial outputs and temporary .ass files after failure, cancellation, or success.
• Add Subtitles to Video — burn editor lot. The burn workflow now opens a shared-helper WinForms editor with a real frame preview, simple time navigation, font / size / color / outline / shadow / position controls, shared ASS preset selection for SRT / FrameShift project inputs, and debounced FFmpeg/libass preview rendering with cancellation of obsolete refreshes. External .ass files stay in style passthrough mode and clearly disable non-applicable controls.
• Add Subtitles to Video — animated preview and hardening lot. The burn editor now adds a short animated preview loop generated from a temporary burn clip around the current position, then displayed as a lightweight looping preview without adding a new playback dependency. Burn preparation now uses display-aware subtitle layout for rotated videos, copies external .ass files to temporary working paths for safer Windows path handling, reads .srt text with a UTF-8 then Windows-codepage fallback, cleans preview clip / GIF artifacts on cancellation or refresh, and surfaces a clear HDR warning when subtitle burn-in may alter colorimetry.
• Add Subtitles to Video — product integration lot. The action is now finalized as a product surface: definitively registered in ActionRegistry, routed through the standard launcher/UI/CLI flow, listed in the active docs, and integrated into the Inno Setup packaging with its own video component, bundled ffmpeg / ffprobe dependencies, and an Explorer video context-menu entry labeled Add subtitles to video.
