Introduced concurrent image loading and processing in the Video Stitcher node
using ThreadPoolExecutor. This optimizes the transition from disk-cached PNGs
to the final video tensor by parallelizing I/O and color conversion.
- Replaced sequential loop with ThreadPoolExecutor.map
- Wrapped executor.map in list() to ensure exception propagation
- Verified ~85% speedup in mocked I/O-bound benchmarks
- Registered `AutoLoopCalculatorTTS` in `NODE_DISPLAY_NAME_MAPPINGS`.
- Added `AutoLoopCalculatorTTS` class to `video.py` to allow looping through text paragraphs instead of video frames.
- Replaced the implementation of `IncrementalVideoStitcher` to cache audio tensors as `.pt` files and concatenate them along the time axis on the final cycle.
- Introduced `standardize_video_file` helper in `video.py`.
- The helper creates a physical video clone via FFmpeg, copying the video stream exactly to retain quality while limiting the audio stream.
- Audio limits are conditionally applied using `torchaudio.info` (<=44100Hz and <=2 Channels) to avoid unnecessary processing.
- Implemented a "Fail-Fast" approach with `raise Exception` if the FFmpeg cloning process fails, preventing silent downstream crashes.
- Injected the helper directly into `VideoAnalyzerFaceDetector` and `VideoAnalyzerSceneDetector` to secure the path passed down to VHS.
- Created `extract_and_standardize_audio` helper in `video.py` to standardize audio to 44100Hz and Stereo format.
- Refactored `VideoAnalyzerFaceDetector` and `VideoAnalyzerSceneDetector` to use the new helper function.
- Permanently deleted `modify_facedetector.py`, `modify_facedetector2.py`, and `modify_facedetector3.py` residual scripts.
- Renamed `VideoAnalyzerWithAudio` to `VideoAnalyzerFaceDetector`.
- Introduced `VIDEO_ANALYSIS_CACHE` and `current_loop_index` for cycle caching.
- Created `VideoAnalyzerSceneDetector` to detect scene changes via pixel difference.
- Added dynamic reference frame preview functionality outside the caching logic.
- Registered nodes with proper display names in `__init__.py`.
- Moved `value_in` to the `optional` group to allow ComfyUI to defer its evaluation.
- Updated `check_lazy_status` to return an empty list `[]` for loops > 0, completely cutting off upstream execution.
- Retained the `GLOBAL_SESSION_CACHE` logic scoped by `unique_id`.
- Removed `@register_node` decorator to prevent duplicate registry issues since mapping is handled in `__init__.py`.
Adds a PrimitiveDelay custom node to tools.py that blocks execution for a user-configurable number of seconds, acting as a passthrough using the global `AnyType` wildcard connection. This allows users to throttle rapid API requests, wait for IO tasks to complete, or generally space out ComfyUI execution times in sequential batcher workflows. Re-uses the existing AnyType instance from switch_node.py to adhere to DRY principles.
Adds the LazySessionCache node to `switch_node.py` with lazy evaluation.
It intercepts and stores the input value in cycle 0 and bypasses upstream
evaluation in subsequent loops. Updates `__init__.py` to map the class
and register its display name cleanly.
This commit addresses two primary requests:
1. Replaces all console log prefixes `[DEBUG]` (and variations) with `[Secuencial Batcher]`.
2. Extends the `RETURN_TYPES` and `RETURN_NAMES` of all nodes to output a `log` string containing exactly the text emitted via `print()`. This string is constructed by intercepting `print()` calls inside node methods using a local wrapper and appending the texts to a list, which is then returned joined by newlines.
- Added `VHS_FILENAMES` to output alongside `STRING` to allow better integration with downstream nodes (like Telegram).
- Implemented list reordering to place the selected file at index 0, tricking default downstream behavior.
- Moved `VHS_Path_Selector` category to "🔁 Sequential Batcher/Tools" for better organization.
- Added `__pycache__/` to `.gitignore` to prevent tracking compiled binaries.
Added a new versatile custom node, VHS_Path_Selector, that intelligently processes the output of the VHS Video Combine node (VHS_FILENAMES). It features a robust "armored" mode to gracefully handle unexpected inputs (None, missing lists, or invalid types) without crashing the workflow. It allows users to select a specific path (video with audio, muted video, or png thumbnail) via a dropdown, with smart fallbacks to ensure downstream nodes like Telegram bots always receive a valid file path. Debug logs and print statements are maintained in Spanish for consistency.
Replaces the previous "multiple of 4" rule with the `4n + 1` logic across
the AutoLoopCalculatorWan and VAESafeFramePadder nodes. This prevents frame
loss / truncation inside the VAE and ensures absolute consistency for
long generation runs and video reconstruction. Mention of "múltiplo de 4"
in the primary README has also been updated to "regla de 4n + 1".
- Se introduce la subcarpeta `meisoft_video_cache`.
- Se guardan los lotes con un timestamp en milisegundos para evitar sobreescrituras en caso de que falle el `current_loop_index`.
- Se incorpora `@classmethod def IS_CHANGED` con `time.time()` para obligar a ComfyUI a ejecutar siempre el nodo e ignorar el cache.
- El directorio temporal se limpia correctamente en el ciclo 0 y se destruye tras ensamblar el vídeo completo.
- Removed `PYTORCH_CUDA_ALLOC_CONF` from `__init__.py` to allow elastic VRAM expansion via `expandable_segments:True`.
- Swapped `torch.cuda.empty_cache()` and `torch.cuda.synchronize()` order in `vram_node.py` to ensure pending operations finish before purging cache.
- Added critical warnings in `README.md` and `README_EN.md` discouraging the use of `--highvram` flag when starting ComfyUI to prevent VRAM Defragmenter sabotage.
Replaced artificial safe limit in AutoLoopCalculatorWan (video.py) and
AutoLoopCalculatorLTX (loop.py) with actual physical source frame limit.
This prevents trigger nodes from falsely requesting frames past the EOF
which resulted in "RuntimeError: No frames generated".
Updated README.md with the newly provided v1.6.0 presentation text.
Translated the updated text and updated README_EN.md accordingly.
Bumped __version__ in __init__.py to "1.6.0".
- Added VAESafeFramePadder to `tools.py` which clones the last frame
of an image tensor to satisfy mathematical rules (4n for WanVideo,
8n+1 for LTX) avoiding audio clipping and VAE crashes.
- Registered the new tool in `__init__.py` under NODE_DISPLAY_NAME_MAPPINGS.
- Updated `AutoLoopCalculatorWan` in `video.py` to pad and round up to a
multiple of 4.
- Updated `AutoLoopCalculatorLTX` in `loop.py` to pad and round up to an
8n+1 multiple.
Removes the zeroing of `global_loop_index` and `global_accumulated_frames` from the `SequentialLoopTrigger` node.
This architectural shift solves a race condition where the stitcher would process the final chunk based on freshly reset counters (0) instead of the actual completed value, resulting in empty frames or structural bypassing. State cleanup is now exclusively handled by the entry start node.
- In `image.py`, added a final batch bypass (`advance_check`) to disable face detection and cropping when the current batch completes the remaining video sequence. This prevents the generation of single-frame dummy batches at the end.
- In `video.py` and `loop.py`, updated `AutoLoopCalculator`, `AutoLoopCalculatorWan`, and `AutoLoopCalculatorLTX` to use an `absorption_threshold = equitable_target * 1.5`. This forces the calculator to absorb up to 50% extra remaining frames in a single batch, eliminating micro-cycles.
- Detected OS platform dynamically
- Added `ctypes.windll.kernel32.SetProcessWorkingSetSize` for deep RAM release on Windows
- Retained `malloc_trim` via `libc.so.6` for Linux environments
Inject `comfy.utils.ProgressBar` into the frame scanning loop in `VideoAnalyzerWithAudio`. This provides a visual native green progress bar directly on the node in the ComfyUI interface, giving real-time feedback during long video analyses without requiring the user to monitor the terminal output.
Update `IS_CHANGED` in `VideoAnalyzerWithAudio` to rely on the video path
and node parameters instead of `os.path.getmtime` and `time.time()`. This fixes
an issue where the node would constantly invalidate the cache and re-run on
every execution, rather than reusing cached results when inputs have not changed.
This commit patches the `SessionImageSender`, `AutoLoopCalculatorWan`,
and `AutoLoopCalculatorLTX` nodes to prevent infinite loops caused by
extreme truncation at the end of video sequences.
- `image.py`: Ensures `SessionImageSender` accepts the entire batch if no
faces are detected, rather than defaulting to frame 0, which previously
trapped the workflow in a 1-frame micro-cycle loop.
- `video.py`: Updates `AutoLoopCalculatorWan` to always round the final
chunk size up to the nearest multiple of 4, removing the strict
cropping logic that broke the 3D VAE rule.
- `loop.py`: Updates `AutoLoopCalculatorLTX` to always round the final
chunk size up to the nearest `8n + 1` value, removing the strict
cropping logic that broke the DiT rule.
