+<em>The first framework for generic video editing with both visual and textual clues.</em>
+</p>
+
+
+## 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.

+```bash
+cd experts/GroundedSAM
+python -m pip install -e GroundingDINO
+python -m pip install -e segment_anything
+```
+
+### 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](https://huggingface.co/stabilityai/stable-diffusion-2-1-unclip-small)

+
+The code for training these models will be released soon.
+
+Pre-trained model for other experts should be downloaded manually into `checkpoints`:
+- [GroundingDINO](https://github.com/IDEA-Research/GroundingDINO) `wget https://github.com/IDEA-Research/GroundingDINO/releases/download/v0.1.0-alpha2/groundingdino_swinb_cogcoor.pth`

+
+
+
+## Usage
+
+### Data Preprocess
+
+#### Source Video Parsing
+
+**Captioning and VQA**:
+```bash
+python experts/blip_inference.py -d data/<video_name>/images
+```
+
+**Protagonist Segmentation**:
+
+- Frame segmentation with GroundedSAM
+```bash
+python experts/grounded_sam_inference.py -d data/<video_name>/images/0000.jpg -t <protagonist>
+```
+
+- Video object segmentation through the video
+```bash
+python experts/xmem_inference.py -d data/<video_name>/images -v <video_name> --mask_dir <protagonist>.mask
+```
+
+**Control Signals Extraction**:
+```bash
+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**:
+```bash
+python experts/grounded_sam_inference.py -d data/<video_name>/reference_images -t <protagonist> --masked_out
+```
+
+### Training
+
+To fine-tune the text-to-image diffusion models with visual and textual clues, run this command:
+
+```bash
+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:
+
+```bash
+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`

+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
