You need to set the style frames' absolute indices. The indices should be in ascending order and separated by an underscore (_). Example: 0_1_2_3 for 4 style frames. The order of the style frames will be as how you loaded it. More specifically, it is their index in the batch IMAGES torch.Tensor.

Arguments

Refer to FuouM/Ezsynth for full documentation. These are the important ones:

style_idxes: The absolute indices of the style frames
edge_method: Edge detection method. Choose from 'PST', 'Classic', or 'PAGE'.
- PST (Phase Stretch Transform): Good overall structure, but not very detailed.
- Classic: A good balance between structure and detail.
- PAGE (Phase and Gradient Estimation): Great detail, great structure, but slow.
only_mode: Skip blending, only run one pass per sequence Blending essentially run a forward and reverse pass on the same sequence, where the forward uses the first style frame, reverse uses the next style frame.

Since blending takes a very long time, one may want to just do forward or reverse mode.

A forward mode is [0----->]. A reverse mode is [<-----0].
- forward (Will only run forward mode if sequence.mode is blend)
- reverse (Will only run reverse mode if sequence.mode is blend)
- Defaults to none.
do_mask: Whether to apply mask. If False, mask input is ignore. If True, will throw error if mask input is invalid. Defaults to False.
pre_mask (bool): Whether to mask the inputs and styles before RUN or after. Pre-mask takes ~2x time to run per frame. Could be due to Ebsynth.dll implementation. Defaults to False.
feather: Feathering for the masked styled frames applying on top of the original frames. Should not be used with pre_mask == True.
use_gpu_hist_blend: Use Cupy GPU for Histogram Blending (Only affect Blend mode).

Faster than CPU (~100x). Although the first time may takes longer as it is compiling the kernels. Time taken for both is also negligible. Will be ignored if Cupy is not installed.

Defaults to False.

Installation

Use ComfyUI-Manager, or manual install.

You don't need to run install.py if you're manually installing it.

git clone --recurse-submodules https://github.com/FuouM/ComfyUI-EbSynth.git

pip install -r requirements.txt

You may also install Cupy and Cupyx to use GPU for some other operations.
