Overview
This node prepares a sequence of keyframes for a specific segment of a longer video generation process. It takes a batch of input images and an audio track, calculates how many total frames the full video should have based on the audio duration, and then distributes the input images as keyframes across the chosen segment, padding the rest with blank frames. It also extracts the corresponding portion of the audio for that segment.Inputs
| Parameter | Description | Data Type | Required | Range |
|---|---|---|---|---|
images | The input images to be distributed as keyframes. | IMAGE | Yes | Batch of images |

segment_index | Which segment this is (0 for first, 1 for second, etc., default: 0). | INT | Yes | 0 to 100 |
audio | Audio to calculate total output frames from and extract segment audio. | AUDIO | Yes | Audio data |
