2D Film Reel
Film 2D enables annotators and reviewers to closely inspect object annotations captured across camera sensors. After an object is labeled and tracked in a camera view, reviewers can select that annotation and trigger a 2D film reel. This displays the annotation in a grid view across frames, with the ability to pan and zoom into the relevant area of the image. This makes it far easier to validate accuracy, consistency, and precision in object tracking. The feature is designed to be good and lean on process - ensuring high-quality review without unnecessary complexity.
Use Case
Reviewing a tracked object across multiple frames to confirm annotation accuracy.
Validating object boundaries and positions when zooming into finer image details.
Spot-checking specific annotations during QA before moving to final approval.
Benefits
Improves annotation quality by enabling closer inspection of object details.
Streamlines the review process with an intuitive grid layout for annotations.
Reduces rework by helping reviewers catch errors earlier in the pipeline.
Steps to Use 2D Film Reel
Select a rectangle on the current frame.
Click on the Film Reel icon to open the grid mode.
A panel appears showing the rectangles state across all frames on that specific camera sensor.
Click a cell to activate editing mode:
A blue border appears.
You can now edit position, dimensions.
A keyframe is created, the cell's badge turns blue, and a blue line appears under the frame in the timeline.
Press Esc to exit edit mode; the blue border disappears.
You can scroll across frames within the Film Reel to review all appearances.
Use the trash icon to quickly delete a cuboid from a specific frame.
