🎬 Inference Examples

1. Reference to Video

Reference-to-Video is a model that synthesizes coherent video sequences from 1 to 4 reference images and a text prompt. It excels at maintaining strong identity fidelity and narrative consistency for characters, objects, and backgrounds.

Single-GPU Inference:
python3 generate_video.py --task_type reference_to_video --ref_imgs "https://skyreels-api.oss-accelerate.aliyuncs.com/examples/subject_reference/0_1.png,https://skyreels-api.oss-accelerate.aliyuncs.com/examples/subject_reference/0_2.png" --prompt "In a dimly lit, cluttered occult club room adorned with shelves full of books, skulls, and mysterious dolls, two young Asian girls are talking. One girl has vibrant teal pigtails with bangs, wearing a white collared polo shirt, while the other has a sleek black bob with bangs, also in a white polo shirt, conversing under the hum of fluorescent lights, a high-quality and detailed cinematic shot." --duration 5 --offload
Multi-GPU Inference (xDiT USP):
torchrun --nproc_per_node=4 generate_video.py --task_type reference_to_video --ref_imgs "https://skyreels-api.oss-accelerate.aliyuncs.com/examples/subject_reference/0_1.png,https://skyreels-api.oss-accelerate.aliyuncs.com/examples/subject_reference/0_2.png" --prompt "In a dimly lit, cluttered occult club room adorned with shelves full of books, skulls, and mysterious dolls, two young Asian girls are talking. One girl has vibrant teal pigtails with bangs, wearing a white collared polo shirt, while the other has a sleek black bob with bangs, also in a white polo shirt, conversing under the hum of fluorescent lights, a high-quality and detailed cinematic shot." --duration 5 --offload --use_usp

💡 Notes:

The --task_type parameter must be set to reference_to_video.

The --ref_imgs parameter accepts 1 to 4 reference images. When providing multiple images, please separate their paths or URLs with commas.

The recommended output specification for this model is a 5-second video at 720p and 24 fps.

2. Video Extension

Extends existing videos while preserving motion continuity, scene coherence, and subject identity.

A. Single-shot Video Extension (5s to 30s)

Single-GPU Inference:
python3 generate_video.py --task_type single_shot_extension --input_video https://skyreels-api.oss-accelerate.aliyuncs.com/examples/video_extension/test.mp4 --prompt "A man is making his way forward slowly, leaning on a white cane to prop himself up." --duration 5 --offload
Multi-GPU Inference (xDiT USP):
torchrun --nproc_per_node=4 generate_video.py --task_type single_shot_extension --input_video https://skyreels-api.oss-accelerate.aliyuncs.com/examples/video_extension/test.mp4 --prompt "A man is making his way forward slowly, leaning on a white cane to prop himself up." --duration 5 --offload --use_usp

💡 Notes:

The --task_type parameter must be set to single_shot_extension.

The --input_video parameter specifies the source video to be extended. Since the single_shot_extension model supports extensions of 5 to 30 seconds, the --duration parameter accepts an integer value within this range.

B. Shot Switching Video Extension (Cinematic Transitions)

Supports transitions like "Cut-In", "Cut-Out", "Shot/Reverse Shot", etc. (Limited to 5s).

Single-GPU Inference:
python3 generate_video.py --task_type shot_switching_extension --input_video https://skyreels-api.oss-accelerate.aliyuncs.com/examples/video_extension/test.mp4 --prompt "[ZOOM_IN_CUT] The scene cuts from a medium shot of a visually impaired man walking on a path in a park. The shot then cut in to a close-up of the man's face and upper torso. The visually impaired Black man is shown from the chest up, wearing dark sunglasses, a grey turtleneck scarf, and a light olive green jacket. His head is held straight, looking forward towards the camera, continuing his walk. The lighting is natural and bright. The background is a soft blur of green trees and foliage from the park." --offload
Multi-GPU Inference (xDiT USP):
torchrun --nproc_per_node=4 generate_video.py --task_type shot_switching_extension --input_video https://skyreels-api.oss-accelerate.aliyuncs.com/examples/video_extension/test.mp4 --prompt "[ZOOM_IN_CUT] The scene cuts from a medium shot of a visually impaired man walking on a path in a park. The shot then cut in to a close-up of the man's face and upper torso. The visually impaired Black man is shown from the chest up, wearing dark sunglasses, a grey turtleneck scarf, and a light olive green jacket. His head is held straight, looking forward towards the camera, continuing his walk. The lighting is natural and bright. The background is a soft blur of green trees and foliage from the park." --offload --use_usp

💡 Notes:

The --task_type parameter must be set to shot_switching_extension.

The --input_video parameter specifies the source video to be extended, and the --duration parameter is therefore limited to a maximum of 5 seconds.

To effectively utilize the supported cinematography types ("Cut-In", "Cut-Out", "Shot/Reverse Shot", "Multi-Angle", "Cut Away"), you can use a Large Language Model (LLM) to craft and optimize your generation prompts, ensuring clear and precise creative direction.

3. Talking Avatar

Generates lifelike talking avatars from a single portrait and an audio clip (up to 200s).

Single-GPU Inference:
python3 generate_video.py --task_type talking_avatar --prompt "A woman is giving a speech. She is confident, poised, and joyful. Use a static shot." --seed 42 --offload --input_image "https://skyreels-api.oss-accelerate.aliyuncs.com/examples/talking_avatar_video/woman.JPEG" --input_audio "https://skyreels-api.oss-accelerate.aliyuncs.com/examples/talking_avatar_video/single_actor/woman_speech.mp3"
Multi-GPU Inference (xDiT USP):

💡 Notes:

The --task_type parameter must be set to talking_avatar.

The --input_image parameter specifies the first-frame image for talking avatar generation (URL or local path). Supported formats: jpg/jpeg, png, gif, bmp.

The --input_audio parameter specifies the driving audio (URL or local path). Currently supports one audio track. Supported formats: mp3, wav. Audio duration must be <= 200 seconds.

📉 Memory Optimization (Low VRAM)

For GPUs with lower VRAM (e.g., under 24GB), use these options:

Add the --low_vram flag to enable FP8 weight-only quantization and block offload.
Lower the output --resolution (default is 720P; try 540P or 480P).

Example:

export PYTORCH_CUDA_ALLOC_CONF="expandable_segments:True" && python3 generate_video.py --low_vram --resolution 540P ...
