In Progress Tab Enhancements:
- Added animated striped progress bars to in-progress jobs
- Exported ModuleColor function for reuse across modules
- Shows real-time progress (0-100%) with module-specific colors
- Progress updates automatically as jobs run
- Maintains consistent visual style with queue view
Lossless Quality Preset Improvements:
- H.265 and AV1 now support all bitrate modes with lossless quality
- Lossless with Target Size mode now works for H.265/AV1
- H.264 and MPEG-2 no longer show "Lossless" option (codec limitation)
- Dynamic quality dropdown updates based on selected codec
- Automatic fallback to "Near-Lossless" when switching from lossless-capable
codec to non-lossless codec
Quality Options Logic:
- Base options: Draft, Standard, Balanced, High, Near-Lossless
- "Lossless" only appears for H.265 and AV1
- codecSupportsLossless() helper function checks compatibility
- updateQualityOptions() refreshes dropdown when codec changes
Lossless + Bitrate Mode Combinations:
- Lossless + CRF: Forces CRF 0 for perfect quality
- Lossless + CBR: Constant bitrate with lossless quality
- Lossless + VBR: Variable bitrate with lossless quality
- Lossless + Target Size: Calculates bitrate for exact file size with
best possible quality (now allowed for H.265/AV1)
Technical Implementation:
- Added Progress field to ui.HistoryEntry struct
- Exported StripedProgress widget and ModuleColor function
- updateQualityOptions() function dynamically filters quality presets
- updateEncodingControls() handles lossless modes per codec
- Descriptive hints explain each lossless+bitrate combination
This allows professional workflows where lossless quality is desired
but file size constraints still need to be met using Target Size mode.

Restructured bitrate controls to hide unused options based on mode,
and improved VBR encoding to use 2-pass for accurate bitrate targeting.
UI Improvements:
- Wrapped CRF, bitrate, and target size controls in hideable containers
- Only show relevant controls based on selected bitrate mode:
* CRF mode: Show only CRF entry
* CBR mode: Show only bitrate entry and presets
* VBR mode: Show only bitrate entry and presets
* Target Size mode: Show only target size controls
- Added descriptive hints for each mode explaining behavior
- Updated DVD mode to work with new container structure
- Made command preview update when bitrate settings change
Encoding Improvements:
- VBR now uses maxrate at 1.5x target for quality peaks
- VBR automatically enables 2-pass encoding for accuracy
- CBR remains strict (minrate=maxrate=target) for guaranteed bitrate
- Target Size mode continues to calculate exact bitrate from duration
This addresses runaway bitrate issues by:
1. Making it clear which mode is active
2. Hiding confusing unused controls
3. Ensuring VBR hits target average bitrate with 2-pass
4. Keeping CBR strict for exact constant bitrate
Pros of manual bitrate targeting:
- Predictable file sizes
- Meets strict size requirements
- Good for streaming with bandwidth constraints
Cons of manual bitrate targeting:
- Variable quality (simple scenes waste bits, complex scenes starve)
- Less efficient than CRF overall
- Requires 2-pass for VBR accuracy (slower)

Implemented the foundation for FFmpeg command copy functionality:
1. Created FFmpegCommandWidget (components.go):
- Displays FFmpeg commands in scrollable monospace text
- Includes "Copy Command" button with clipboard integration
- Shows confirmation dialog when copied
- Reusable widget for consistent UI across modules
2. Created buildFFmpegCommandFromJob() function (main.go):
- Extracts FFmpeg command from queue job config
- Uses INPUT/OUTPUT placeholders for portability
- Handles video filters (deinterlace, crop, scale, aspect, flip, rotate, fps)
- Handles video codecs with hardware acceleration (H.264, H.265, AV1, VP9)
- Handles quality modes (CRF, CBR, VBR)
- Handles audio codecs and settings
- Covers ~90% of convert job scenarios
This infrastructure enables users to copy the exact FFmpeg command
being used for conversions, making it easy to reproduce VideoTools'
output in external tools like Topaz or command-line ffmpeg.
Next phase will integrate this into the Convert module UI, queue view,
and conversion history sidebar.

- Create mouseButtonHandler widget to capture mouse button events
- Wrap all content with mouseButtonHandler in setContent
- Track history in showModule and showMainMenu
- Handle mouse button 4 (back) and mouse button 5 (forward)
- Maintain history of up to 50 module navigations
Mouse back/forward buttons now work like a web browser - press the back button
to return to previous modules, press forward to go back to where you were.
History is maintained across all module transitions for seamless navigation.
- Add check in loadPersistedConvertConfig to default FrameRate to "Source" if empty
- Add check after loading persisted config to ensure FrameRate is "Source" if not set
- Prevents unwanted frame rate conversions from persisted config overriding safe defaults
This ensures that frame rate always defaults to "Source" and users won't
accidentally convert all their videos to 23.976fps or another frame rate
if they had previously saved a config with a specific frame rate set.
- Add upscaleFrameRate and upscaleMotionInterpolation fields to appState
- Add Frame Rate section to upscale UI with dropdown and motion interpolation checkbox
- Pass frame rate settings through upscale job config
- Implement frame rate conversion in executeUpscaleJob using minterpolate or fps filter
- Frame rate section appears after resolution selection in upscale settings
Frame rate control is now available in both convert and upscale modules,
allowing users to standardize content from different regions with optional
motion interpolation for smooth conversion.
- Add UseMotionInterpolation field to convertConfig struct
- Implement minterpolate filter for smooth frame rate changes when enabled
- Add UI checkbox in advanced settings for motion interpolation option
- Use minterpolate with high-quality settings (mci mode, aobmc, bidir ME, vsbmc)
- Falls back to simple fps filter when motion interpolation is disabled
- Fix pre-existing statusBar function calls (renamed to moduleFooter)
Motion interpolation provides smooth frame rate conversion (e.g., 24fps→60fps)
using motion-compensated interpolation instead of simple frame duplication.
This is useful for standardizing content from different regions.
Removed confirmation dialog popups when converting files with
chapters to DVD format. Instead, show a non-intrusive inline
warning label that appears/disappears based on format selection.
Warning label:
- Shows only when file has chapters AND DVD format is selected
- Displays inline below format selector in both simple and advanced modes
- No user action required - just informational
- Text: "Chapters will be lost - DVD format doesn't support embedded chapters. Use MKV/MP4 to preserve chapters."
When converting a file with chapters to DVD/MPEG format, show
a confirmation dialog warning the user that chapters will be lost.
MPEG format does not support embedded chapters - they require
full DVD authoring with IFO files. Users are warned and given
the option to cancel or continue.
Warning appears for both 'Convert Now' and 'Add to Queue' buttons.
Added -show_chapters flag to ffprobe command to retrieve chapter
information. Parse chapters from JSON output and set HasChapters
field when chapters are present.
Files with chapters will now correctly show 'Chapters: Yes' in
the file information display.
Added explicit stream mapping to preserve all streams:
- Map video, audio, and subtitle streams (subtitles optional)
- Added -map_chapters to preserve chapter information
- Added -map_metadata to preserve all file metadata
- Copy subtitle streams without re-encoding
Applies to both conversions with and without cover art.
Works for all output formats that support these features.
Removed -target ntsc-dvd and -target pal-dvd preset flags which
strip metadata including chapters. Instead, manually specify all
DVD parameters (bitrate, maxrate, bufsize, format) to maintain
full control and preserve chapter metadata.
Chapters now retained in both new 'dvd' format and legacy DVD formats.
When 'Clear Completed' empties the queue, return to the previous
module instead of staying in an empty queue view. If jobs remain
after clearing, stay in queue view and refresh.
Changed 'Clear All' behavior to return to the last active module
instead of always going to main menu. Falls back to main menu
if no previous module is tracked or if coming from queue itself.
Added clearer format descriptions:
- "Fast Merge (No Re-encoding)" instead of "MKV (Copy streams)"
- "Lossless MKV (Best Quality)" - new option with slow preset, CRF 18, FLAC audio
- "High Quality MP4 (H.264/H.265)" instead of technical codec names
- "DVD Format" with conditional region/aspect selectors
- "Blu-ray Format" instead of "Blu-ray (H.264)"
DVD Format improvements:
- When "DVD Format" is selected, shows Region (NTSC/PAL) and Aspect (16:9/4:3) options
- Options hidden for other formats
- Stored in state and passed to merge job config
- Updated execution to use DVD region/aspect settings
Maintains backward compatibility with legacy DVD format codes.
WMV Encoder Fix:
- WMV files now use wmv2 encoder (ffmpeg compatible) instead of wmv3
- Audio uses wmav2 for WMV files
- High quality bitrate (2000k) for WMV video
- Fallback handling for unsupported source codecs
UI Simplification:
- Changed "High Quality (source format/codecs)" to "Match Source Format"
- Simplified hint text to just "Unchecked = Use Conversion Settings"
- More concise and less confusing labels
Snippet Quality Improvements:
- High Quality mode now detects and uses source codecs (WMV stays WMV)
- Uses conversion panel's encoder preset (e.g., 'slow') instead of hardcoded 'ultrafast'
- Uses conversion panel's CRF setting for quality control
- Outputs to source file extension in High Quality mode
- Updated UI label to "High Quality (source format/codecs)"
Workflow Streamlining:
- Removed popup dialog when loading multiple videos
- Showing convert view is sufficient feedback
- Failed files logged instead of shown in dialog
UI Fixes:
- Status label no longer wraps to new line on action bar
- Set text truncation to keep status on single line
Changed snippet "Default Format" mode from stream copy to re-encoding with
high quality settings (libx264, CRF 17, ultrafast preset). Stream copy
cannot provide precise durations as it can only cut at keyframe boundaries.
Both snippet modes now output MP4 and re-encode. The difference is quality:
- High Quality mode: CRF 17, ultrafast preset
- Conversion Settings mode: Uses configured output settings
Updated UI labels to reflect "Snippet Quality" instead of output format.

Reverts the problematic -accurate_seek and -to flags that caused wildly incorrect durations (9:40 instead of 10s). Returns to the standard, reliable FFmpeg pattern for stream copy:
ffmpeg -ss START -i input -t DURATION -c copy output
This places -ss before -i for fast keyframe seeking and uses -t for duration (not -to which is an absolute timestamp causing incorrect extraction). Should now correctly extract the configured snippet length centered on video midpoint.

- Changing from -t (duration) to -to (end time) for better accuracy
- Adding -avoid_negative_ts make_zero to fix timestamp issues with problematic containers like WMV
This should resolve issues where snippets were 1:20 or 0:21 instead of the configured length (e.g., 10s). Stream copy still uses keyframe-level precision but should now be much closer to target duration.

Fixed the exit 234 error when generating individual thumbnails by
disabling the timestamp overlay feature which was causing FFmpeg
font-related failures on some systems.
Changes:
- ShowTimestamp: false (was true)
- ShowMetadata: only true for contact sheets (was always true)
The timestamp overlay was causing issues because:
1. DejaVu Sans Mono font might not be available on all systems
2. FFmpeg exits with code 234 when drawtext filter fails
3. Individual thumbnails don't need timestamp overlays anyway
Contact sheets still get metadata headers, which is the main use case

thumbnails (was missing, causing FFmpeg to fail)
- Output directory: Changed from temp to video's directory, creating a
folder named "{video}_thumbnails" next to the source file
New Features:
- Added video preview window to thumbnail module (640x360)
- Split layout: preview on left (55%), settings on right (45%)
- Preview uses same buildVideoPane as other modules for consistency
The thumbnail module now has a proper preview window for reviewing
the loaded video before generating thumbnails, and outputs are saved
in a logical location next to the source file.

Changed snippet extraction to use stream copy instead of re-encoding:
- Removed all convert config and encoding logic
- Now uses `-c copy` to copy all streams without re-encoding
- Uses same file extension as source for container compatibility
- Much faster extraction with no quality loss
- Updated job description to indicate "source settings"
This makes snippet generation instant instead of requiring full re-encode.

The issue was that FFmpeg's out_time_ms field is actually in microseconds
(not milliseconds despite the name). We were dividing by 1,000 when we
should have been dividing by 1,000,000 to convert to seconds.
This caused the progress calculation to be off by 1000x, making it
immediately jump to 100% even though the job was just starting.
Also added comprehensive debug logging to track progress samples and
identify calculation issues in the future.

Issue: File list only used half the vertical space, wasting screen real estate.
Changed left panel from VBox to Border layout:
- Top: "Clips to Merge" label and Add/Clear buttons (fixed size)
- Center: File list scroll area (expands to fill remaining space)
The border layout gives the scroll area priority to expand vertically,
maximizing the visible file list area. This is especially important
when merging many clips.

User reports progress jumps to 100% within 10 seconds but merge continues for 45s total.
Added comprehensive debug logging to track:
- Individual clip durations as they're summed
- Total expected duration for the merge
- Exact moment when progress hits 100% with actual vs expected times
- Only update progress when it changes by ≥0.1% (reduces callback spam)
This will help diagnose whether:
- Clip durations are being calculated incorrectly
- FFmpeg's out_time_ms doesn't match expected total duration
- Concat demuxer reports different output duration than sum of inputs
Logging appears in logs/videotools.log with CatFFMPEG category.

Issues fixed:
- Missing file extensions caused FFmpeg errors (user's job 234 failure)
- Limited codec options (only copy or H.265)
- Manual codec mode selector was redundant
Changes:
1. Auto file extension handling:
- Automatically adds/corrects extension based on selected format
- .mkv for MKV/Blu-ray formats
- .mpg for DVD formats
- .mp4 for MP4 formats
- Validates and fixes extension in addMergeToQueue
2. Expanded format options:
- MKV (Copy streams) - stream copy, no re-encoding
- MKV (H.264) - re-encode with H.264, CRF 23
- MKV (H.265) - re-encode with H.265, CRF 28
- MP4 (H.264) - H.264 + AAC audio, web-optimized
- MP4 (H.265) - H.265 + AAC audio, web-optimized
- DVD NTSC/PAL (16:9 and 4:3)
- Blu-ray (H.264)
3. Removed redundant codec mode selector:
- Format dropdown now explicitly includes codec choice
- Cleaner, more intuitive UI
- Backward compatible with old queue jobs
Extension is auto-updated when:
- User selects a different format (updates existing path extension)
- User adds merge to queue (validates/fixes before encoding)
- Prevents errors from missing or wrong file extensions

The -progress flag was being added AFTER the output path in the FFmpeg command,
causing FFmpeg to not recognize it and therefore not output progress information.
Moved -progress pipe:1 -nostats to appear BEFORE the output path.
Now merge jobs will correctly report progress as they encode:
- Progress starts at 0%
- Updates based on out_time_ms from FFmpeg progress output
- Calculates percentage based on total duration of all clips
- Shows accurate real-time progress in queue view and stats bar

The Merge module's ui.NewDroppable wrappers weren't receiving drop events
because the window-level handleDrop function was intercepting them first.
Added merge module handling to handleDrop function:
- Accepts individual video files and adds them sequentially to merge clips
- Accepts multiple files at once and processes all in order
- Accepts folders and recursively finds all video files
- Probes each video to get duration and metadata
- Sets chapter names defaulting to filename
- Auto-sets output path to "merged.mkv" once 2+ clips are added
- Refreshes UI after each clip is added
Now drag-and-drop works consistently across all modules (Convert, Compare, Inspect, Merge).
