By loading nodes in batches, you can build a workflow for batch generation of digital humans, which is particularly suitable for beginners. You can split audio into multiple batches according to preset settings and generate videos with specified multiple portrait photos. This method significantly boosts efficiency in creating multi-segment or multi-character videos, surpassing the performance of for loop nodes, and is also easier to expand. It can be considered a small batch processing technique.

Usage:

1. Upload audio and set the split audio length (seconds)
2. Based on the length, set the start time point (seconds)
3. Set the portrait directory and adjust the resolution
4. Set the execution batch based on the split number
5. Run

通过批次加载节点，搭建批量生成数字人工作流，比较适合新手，可将音频按预设拆分为多个批次，进行指定多个人像照片的视频生成，在多片段或多人物视频制作上效率飙升，不输for循环节点，且更易于扩展，也算是一个批处理的小技巧。

用法：

1、上传音频，设置拆分音频长度（秒）

2、基于长度，设置起始时间点（秒）

3、设置人像目录，调整分辨率

4、根据拆分数量，设置执行批次

5、运行
