New post-export step that multiplies the frame count by interpolating
between every consecutive frame pair. Supports 2x/4x/8x multipliers
using RIFE, FILM, or BiM-VFI methods.
- Add frame interpolation checkbox, multiplier combo (2x/4x/8x), and
method combo (RIFE/FILM/BiM-VFI) to Export Options group
- Implement _frame_interpolation_pass: works in log2(multiplier) passes,
each pass doubles frames by inserting midpoint interpolations
- Uses _fi_ temp prefix during rename to avoid filename collisions
- Preserves per-file extensions for mixed-format sequences
- Handles cancellation gracefully (renames temp files back)
- Runs after transition export, before optional video encoding
- Also clean up leftover _fi_ temp files in orphan removal

- Fix _sequence_frame_count excluding direct interpolation frames,
which caused export range max to be too small and truncate output
- Fix blend_images call missing optical flow parameters (of_levels,
of_winsize, of_iterations, of_poly_n, of_poly_sigma) — optical
flow blends in transition export used defaults instead of user config
- Fix progress bar not reaching 100% when direct interpolation is
used — current_op was never incremented for generated frames
- Fix BiM-VFI temp files (bimvfi_temp_*.png) not cleaned up by
orphan removal in manager.py
- Update "+" row text to say "AI transition" instead of "RIFE/FILM"

- Fix _delete_current_image: delegate to _remove_selected_files so
deletions are tracked in _removed_files / trim adjustments and
survive _refresh_files calls and session save/restore
- Fix _auto_save_session: reuse _current_session_id when available
instead of always creating new sessions. Clean up old autosave
sessions for the same destination to prevent unbounded accumulation.
- Fix signal cascade in _on_destination_changed: blockSignals around
_add_to_path_history to prevent currentIndexChanged re-entry

- Fix critical import: use `from modules.components import make_components`
instead of `from modules.components.components` so the @register
decorator fires and the model can be instantiated
- Use separate venv (venv-bimvfi) to avoid dependency conflicts with
RIFE/FILM — basicsr-fixed/cupy/lpips can break the shared venv
- BimVfiEnv now creates its own venv with PyTorch, independent of RIFE
- Remove dead code: dis0/dis1/scale_factor/ratio/nr_lvl_skipped kwargs
are silently ignored by model's **kwargs, and get_scale_factor/
get_pyr_level were computing unused values
- Use model's trained pyr_level=3 (set at construction) instead of
overriding to 5-7 at inference which was untested
- Use `python -m pip` and `python -m gdown` instead of direct binaries
for cross-platform reliability
- Add checkpoint size validation (>1MB) on download
- Verify torch importable in is_setup() instead of just checking files
- Update UI: BiM-VFI setup flow is independent, doesn't need RIFE first

Integrate KAIST VICLab's BiM-VFI (CVPR 2025) as a third option
alongside RIFE and FILM for AI frame interpolation between sequences.
- Add BIM_VFI enum value to DirectInterpolationMethod
- Create core/bim_vfi_worker.py subprocess worker following FILM pattern
- Add BimVfiEnv class managing repo clone, deps install, and checkpoint
download (via gdown from Google Drive)
- Add batch and single-frame dispatch in TransitionGenerator
- Add bim_vfi_blend() to ImageBlender with FILM fallback
- Update DirectTransitionDialog UI with BiM-VFI option and setup flow
BiM-VFI setup auto-clones the repo, installs deps (cupy, basicsr-fixed,
etc.) into the shared PyTorch venv, and downloads the checkpoint.

- Fix RIFE warp() grid cache: move backwarp_tenGrid to module level so it persists across calls
- Fix FILM partial download: download to .tmp file then atomically rename, validate file size
- Fix fid_to_pos orphan fallthrough: use .get(fid) with None check instead of defaulting to 0
- Fix commonpath ValueError: guard against mixed-drive paths on Windows
- Fix ON CONFLICT clause in direct_transition_settings to match UNIQUE constraint
- Remove dead save_folder_type_override method from database
- Fix subprocess resource leaks in video.py: add try/except/kill around proc loops
- Fix concat file handle leak: wrap writes in try/finally
- Fix format conversion in transition export: normalize extension comparison
- Fix session restore loop: blockSignals during destination path changes
- Fix missing folder handling: keep as placeholders instead of skipping
- Fix fid=0 skip guard in _restore_files_from_session

Missing folders now show in red with (MISSING) tag instead of silently
disappearing. Auto-save always persists session settings (folder order,
trims, transitions) even when folders are missing, so the session
layout survives for later replacement via right-click > Replace Folder.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
_set_folder_type was missing a _refresh_files() call, so changing a
folder between TRANSITION and MAIN didn't rebuild the file list until
a manual reorder.

Removing files contiguous from the start/end of a sequence now adjusts
the trim handles instead of tracking them as individual removals, so
dragging the slider back restores them. Middle removals still tracked
separately.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The trim label now shows removed file count alongside trim range,
e.g. "Frames 1-81 of 81 (78 included, 3 removed)" instead of
always showing the full disk count.

- Add locked column to sessions with toggle in restore dialog, preventing
accidental deletion of important sessions (padlock icon, DB-level protection)
- Fix transition export copying source files as-is when output format differs
(e.g. webp sources now convert to png when png format is selected)
- Fix ON CONFLICT clause in save_per_transition_settings to match UNIQUE constraint

Adds right-click context menu on empty source list space with "Cleanup Unused Videos..."
option that scans type_of_video/ directories for video folders not in the current session,
showing a dialog with checkboxes to delete or move them to .trash/.

- Make each transition boundary symmetric (left_overlap controls MAIN→TRANS,
right_overlap controls TRANS→MAIN) so frame indices map 1:1 with no repeats
- Track committed frames per folder to cap overlaps and prevent over-allocation
- Fix float truncation in frame mapping (int→round) that caused off-by-one dupes
- Sync trim slider to follow frame selection in Sequence Order / With Transitions
- Defer expensive file list rebuild to mouse release for smooth trim slider drag
- Apply trim settings to transition folders in both display and export paths
- Refresh trim slider after session restore to show correct file counts

Refactor folder settings from path-keyed to fid-keyed dicts so the same
physical folder can appear multiple times with independent trim, type,
and transition settings. This enables splitting a MAIN folder into two
sub-sequences at an arbitrary frame boundary using complementary trim
ranges, and merging them back.
- Add split from file list context menu ("Split Sequence After This
Frame") and source list context menu ("Split Sequence..." dialog)
- Add "Merge with Next" to undo splits on adjacent same-path entries
- Sub-sequences share the base sequence number (seq01-1, seq01-2) with
continuous file indices so subsequent sequences are not renumbered
- Session save/restore handles duplicate paths via folder_order; restore
falls back to _refresh_files when split entries are detected
- Export copy_matches now compares file contents when size matches but
mtime differs, preventing false negatives on re-export

- Stop restoring OF preset from session so widget default (Max) always applies
- Add minimum widths and size policies to content_splitter children
- Change sequence_table Main Frame column from Stretch to Interactive

setStretchFactor on QSplitter interferes with manual handle dragging —
Qt applies stretch redistribution after each mouse move, compounding
the delta and creating an accelerating effect. Replaced with size
policies (Expanding on right panel) which achieve the same window-
resize behavior without fighting the splitter drag.

The right-side time label was drawn at the viewport edge, overlapping
the # column when frame numbers had 3+ digits. Now drawn at the right
edge of column 1 (before the # column starts).

Both splitters now have setChildrenCollapsible(False) so neither side
can be dragged to zero width. Right panel gets minWidth 400 to stay
usable when the source panel is expanded.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
The source panel had maxWidth(400) which barely let the splitter move
beyond its starting position. Removed the cap, lowered minWidth from
250 to 150, and widened both splitter handles to 5px for easier grab.

ResizeToContents columns can't be dragged — they snap back to their
computed width, making resize attempts feel broken. Changed to
Interactive mode with explicit initial widths and minimum section
size so columns are freely draggable while still having sensible
defaults.

- Session list now supports extended selection (Shift+click for range,
Ctrl+click for individual)
- "Delete Selected" button removes chosen sessions with confirmation
- List refreshes in-place after deletion so you can keep cleaning up
- Added delete_sessions() batch method to database (single transaction)
- Simplified delete_session() to rely on ON DELETE CASCADE

The export loop was opening a new DB connection per file AND starving
the Qt event loop, causing the progress bar to freeze then jump and
the app to crash during large copy exports.
Fixes:
- All record_symlink calls in both export paths now collect records
and batch-insert in a single transaction at the end
- Added explicit QApplication.processEvents() in export loops
- Throttled progress label updates to every 10 files (text rendering
was adding overhead on every iteration)
- Moved shutil import out of inner loops

Right-click any folder in the source list → "Replace Folder..." opens
a file dialog. The new folder takes the old one's position and inherits
all settings: type override, trim, per-transition overlap, removed
files, and direct transition config.

Save freeze fix:
- Added record_symlinks_batch() that inserts all symlinks in a single
DB transaction instead of opening a new connection per file
- _save_session and _auto_save_session now use batch inserts
- With 1700 files this goes from 1700 connection cycles to 1
Removed files fix:
- _restore_files_from_session now filters by _removed_files so
individually deleted files stay removed even when restoring from
session data that pre-dates the removal
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
Session restore fixes:
- AUTO-typed folders now default to MAIN on restore instead of using
position-based index%2, which silently flipped half the folders to
TRANSITION when restoring legacy sessions
- All restored folders get explicit type overrides so no folder relies
on position-based typing after restore
- TRANSITION folders with symlink data are auto-recovered as MAIN
(catches incorrectly saved types from older export paths)
- Export Sequence path now saves with save_effective_types=True,
preventing folder type loss
- Removed redundant trim-only save that used unresolved paths
- Auto-save guards against overwriting sessions with empty file lists
UI improvements:
- Added 4th "Frame" column to Sequence Order tab showing overall
frame number (1-based)
- Last frame of each sequence is bold for visual clarity
- Fixed column resizing (ResizeToContents + Stretch) to prevent
column collapse bugs
- Save Session dialog now reports main + transition folder counts
- Default optical flow preset changed to Max
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Fix export range not covering TRANSITION folder middle frames: range max
was based on MAIN-only file count, causing blends at sequence end to be
silently skipped. Now uses full sequence frame count from preview table.
- Fix preview table not counting TRANSITION middle frames: these frames are
output as symlinks in export but were shown without sequence numbers in
preview. Now displayed as [T] entries with proper output_seq numbering.
- Fix session restore path resolution: all folder paths now .resolve()'d on
save and restored with _resolve_lookup() fallback for both raw and resolved
forms. Fixes folder order corruption on restore.
- Fix legacy session restore: detect pre-migration sessions (all folder_order=0)
and fall back to symlink-derived ordering with get_all_folder_settings().
- Fix ffmpeg concat demuxer duration format: use decimal instead of fraction.
- Fix QProgressDialog false cancellation from autoReset at max value.
- Fix Export with Transitions skipping TRANSITION folders entirely while
preview processed them, causing cutoff at blend boundaries.
- Fix Encode Video Only not finding transition-exported files in trans_dest.
- Add video encoding module (core/video.py) with concat demuxer support.
- Add direct_transition_settings DB table and persistence.
- Add sticky folder types on reorder and placeholder transition slots.
- Add blend-skipped-range counter to export completion dialog.
Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
- Rewrite _export_sequence with QProgressDialog, per-file error handling,
cancel support, and continuous seq_00000 naming
- Add folder progress labels to _process_with_transitions
- Extend cleanup_old_links to remove film_temp_*.png temporaries
- Add copy-files checkbox for Docker/remote destinations
- Persist individually removed files across sessions (removed_files table)
- Recover file removals from export history for older sessions
- Save effective folder types in transition exports for reliable restore

Implement standalone PyTorch-based RIFE interpolation that runs in a
dedicated virtual environment to avoid Qt/OpenCV conflicts:
- Add PracticalRifeEnv class for managing venv and subprocess execution
- Add rife_worker.py standalone interpolation script using Practical-RIFE
- Add RIFE_PRACTICAL blending model with ensemble/fast mode settings
- Add UI controls for Practical-RIFE configuration
- Update .gitignore to exclude venv-rife/ directory
The implementation downloads Practical-RIFE models on first use and runs
interpolation in a separate process with proper progress reporting.
