Abstract

The text-driven image and video diffusion models have achieved unprecedented success in generating realistic and diverse content. Recently, the editing and variation of existing images and videos in diffusion-based generative models have garnered significant attention. However, previous works are limited to editing content with text or providing coarse personalization using a single visual clue, rendering them unsuitable for indescribable content that requires fine-grained and detailed control. In this regard, we propose a generic video editing framework called Make-A-Protagonist, which utilizes textual and visual clues to edit videos with the goal of empowering individuals to become the protagonists. Specifically, we leverage multiple experts to parse source video, target visual and textual clues, and propose a visual-textual-based video generation model that employs mask-guided denoising sampling to generate the desired output. Extensive results demonstrate the versatile and remarkable editing capabilities of Make-A-Protagonist.

Setup

Requirements

• Python>=3.9 and Pytorch>=1.13.1

cd experts/GroundedSAM
pip install -e GroundingDINO

Weights

The following weights from HuggingFace are used in this project. You can download them into checkpoints or load them from HuggingFace repo.

• Stable Diffusion UnCLIP Small
• BLIP-2 Flan T5-xL
• CLIP ViT-L
• DALL-E 2 Prior

ControlNet for Stable Diffusion UnCLIP Small should be downloaded manually into checkpoints:

• ControlNet UnCLIP Small
• You can also train your own ControlNet model with Stable UnCLIP HERE.

Pre-trained model for other experts should be downloaded manually into checkpoints:

• GroundingDINO wget https://github.com/IDEA-Research/GroundingDINO/releases/download/v0.1.0-alpha2/groundingdino_swinb_cogcoor.pth
• Segment Anything wget https://dl.fbaipublicfiles.com/segment_anything/sam_vit_h_4b8939.pth
• XMem wget https://github.com/hkchengrex/XMem/releases/download/v1.0/XMem.pth

Usage

Data Preprocess

Source Video Parsing

Captioning and VQA:

python experts/blip_inference.py -d data/<video_name>/images

Protagonist Segmentation:

• Frame segmentation with GroundedSAM

python experts/grounded_sam_inference.py -d data/<video_name>/images/0000.jpg -t <protagonist>

Note: Since GroundingDINO detects bounding boxes for each noun in the sentence, it is better to use only one noun here. For example, use -t man instead of -t "a man with a basketball".

• Video object segmentation through the video

python experts/xmem_inference.py -d data/<video_name>/images -v <video_name> --mask_dir <protagonist>.mask

Control Signals Extraction:

python experts/controlnet_signal_extraction.py -d data/<video_name>/images -c <control>

Currently we only support two types of control signals: depth and openposefull.

Visual Clue Parsing

Reference Protagonist Segmentation:

python experts/grounded_sam_inference.py -d data/<video_name>/reference_images/<reference_image_name> -t <protagonist> --masked_out

Training

To fine-tune the text-to-image diffusion models with visual and textual clues, run this command:

python train.py --config="configs/<video_name>/train.yaml"

Note: At least 24 GB is requires to train the model.

Inference

Once the training is done, run inference:

python eval.py --config="configs/<video_name>/eval.yaml"

Applications: Three applications are supported by Make-A-Protagonist, which can be achieved by modifying the inference configuration file.

• Protagonist Editing: source_protagonist: true
• Background Editing: source_background: true
• Text-to-Video Editing with Protagonist: source_protagonist: false & source_background: false
