The FiVE-Bench dataset offers a rich, structured benchmark for fine-grained video editing. The dataset includes 420 high-quality source-target prompt pairs spanning six fine-grained video editing tasks:

1. Object Replacement (Rigid)
2. Object Replacement (Non-Rigid)
3. Color Alteration
4. Material Modification
5. Object Addition
6. Object Removal

• Download the dataset from Hugging Face: 🔗 FiVE-Bench on Hugging Face

• Follow the instructions in Installation Guide to download the dataset and install the evaluation code (FiVE_Bench).

• Place the downloaded dataset in the directory: ./FiVE_Bench/data. The data structure should looks like:

Use your video editing method to edit the FiVE-Bench videos based on the provided text prompts and generate the corresponding edited results.

Example implementations of our proposed rectified flow (RF)-based video editing methods are provided provided in the models/ directory:

- **[Pyramid-Edit](models/README.md#pyramid-edit)**: Diffusion-based video editing using Pyramid-Flow architecture

- **[Wan-Edit](models/README.md#wan-edit)**: Rectified flow-based video editing with Wan2.1-T2V-1.3B model

Run Pyramid-Edit:

# Setup model
cd models/pyramid-edit && mkdir -p hf/pyramid-flow-miniflux
# Download model checkpoint to hf/ directory
bash scripts/run_FiVE.sh

Run Wan-Edit:

# Setup model  
cd models/wan-edit && mkdir -p hf/Wan2.1-T2V-1.3B
# Download model checkpoint to hf/ directory
bash scripts/run_FiVE.sh

For detailed setup instructions and configuration options, see the Models Documentation.

Follow the installation guide in Installation Guide to get the evaluation results.

sh scripts/eval_FiVE.sh

Evaluation Support Elements:

• Editing Masks: Generated using SAM2 to assist in localized metric evaluation.

• Editing Instructions: Structured directives for each source-target pair to guide model behavior.

FiVE-Bench provides comprehensive evaluation through two major components:

These metrics quantitatively measure various dimensions of video editing quality:

• Structure Preservation
• Background Preservation
  (PSNR, LPIPS, MSE, SSIM outside the editing mask)
• Edit Prompt–Image Consistency
  (CLIP similarity on full and masked images)
• Image Quality Assessment
  (NIQE)
• Temporal Consistency
  (MFS: Motion Fidelity Score):
• Runtime Efficiency

We use a vision-language model (VLM) to automatically assess whether the intended edits are reflected in the video outputs by asking it questions about the content. If the source video contains a swan, and the target prompt requests a flamingo. For the edited video, we ask

• Yes/No Questions:

  • Is there a swan in the video?
  • Is there a flamingo in the video?

  ✅ The edit is considered successful only if the answers are "No" to the first question and "Yes" to the second.

• Multiple-choice Questions:

  • What is in the video? a) A swan b) A flamingo

  ✅ The edit is considered successful if the model selects the correct target object (e.g., b) A flamingo) and avoids selecting the original source object.

FiVE-Acc evaluates editing success using a vision-language model (VLM) by asking content-related questions:

• YN-Acc: Yes/No question accuracy
• MC-Acc: Multiple-choice question accuracy
• U-Acc: Union accuracy – success if any question is correct
• ∩-Acc: Intersection accuracy – success only if all questions are correct
• FiVE-Acc ↑: Final score = average of all above metrics (higher is better)
