-Hallo has a few simple requirements for input data:
-
-For the source image:
-
-1. It should be cropped into squares.
-2. The face should be the main focus, making up 50%-70% of the image.
-3. The face should be facing forward, with a rotation angle of less than 30° (no side profiles).
-
-For the driving audio:
-
-1. It must be in WAV format.
-2. It must be in English since our training datasets are only in this language.
-3. Ensure the vocals are clear; background music is acceptable.
-
-We have provided some [samples](https://huggingface.co/datasets/fudan-generative-ai/hallo_inference_samples) for your reference.
