• Labelbox - Offers robust features, though its free tier has limits.
• VGG Image Annotator - Geared more towards image annotations but versatile enough for videos.

Step 2: Prepare Your Video Files

Gather the video files you need to annotate. Make sure they are in a format supported by your chosen tool. Organize these videos according to the projects they belong to for easier management.

Step 3: Import Your Video into the Tool

Most tools allow you to upload videos via a simple drag-and-drop interface or an import function. Ensure that your videos are properly loaded before proceeding.

Step 4: Annotate the Video

Begin the annotation process by:

1. Familiarizing yourself with the interface: Understand how to use the various features available.
2. Select the type of annotation. Depending on your needs, this could be bounding boxes, polygons, or segmentation masks.
3. Start marking the video: Play the video and use the tools to annotate. Take care to be as accurate as possible.

Step 5: Review and Edit Annotations

Once you have completed annotating the video, review the annotations for accuracy. This step is crucial in ensuring the quality of your data.

Step 6: Export the Annotations

After finalizing your annotations, use the export feature to save your work in a format compatible with your machine learning framework or any other tool you are using.

Best Practices for Video Annotation

To achieve the best results with any free video annotation tool, adhere to the following best practices:

• Define Clear Guidelines: Establish clear guidelines for your team about how to annotate videos consistently.
• Regular Training Sessions: Conduct training sessions to ensure everyone understands how to use the tool effectively.
• Maintain a Feedback Loop: Create a mechanism for team members to provide feedback on the annotation process and tool usability.
