    Quick Start Guide

    Vollage is an AI-powered rotoscoping and compositing tool that allows you to extract objects from videos quickly and accurately. This guide provides step-by-step instructions to help you navigate and use Vollage efficiently.

    Getting Started

    Opening Vollage

    1. Launch the Vollage application.
    2. Import your video by dragging it into the workspace or clicking Upload Video.

    Video Upload Guidelines

    Before uploading your video, please review the following guidelines:

    • Supported Formats: mp4, mov
    • Recommended Resolution: 720p, 1080p
    • Maximum Video Length: up to 15 seconds
    • Frame Rate Recommendations: 24fps, 30fps

    Following these guidelines ensures optimal performance and accuracy during mask generation.

    Vollage Workflow Overview

    1. Preview

    Step 1: Select Preview Frames

    • Choose a frame that clearly displays the object fully and is well-separated from the background.
    • This frame serves as the reference for generating masks across the entire video, so careful selection is essential.

    Step 2: Draw Mask

    • Use the drawing tool to define the object.
      • Include Mode: Mark areas to be tracked.
      • Exclude Mode: Mark areas that should be ignored during tracking.
    • You can draw multiple sets of points for complex objects or multiple subjects.

    Step 3: Preview

    • Click Preview to generate a temporary mask and see how it tracks the subject.
    • To make adjustments, redraw the mask to overwrite the previous one.

    2. Mask

    Step 1: Create Mask

    • Mask generation settings:

      • Temporal Radius: Amount of frames to consider for continuous tracking. Higher values improves continuity but may seem dull.
      • Filter Type: Choose between guided, amf(adaptive manifold filter), or bilateral for different smoothing effects. guided is recommended for most cases.

    • Once satisfied with the preview, click Create Mask.

    • For a 100-frame Full HD video, mask creation typically takes around 10 seconds.

    Step 2: Mask Edit

    • Click on the mask timeline to access editing tools.
    • You can re-enter the preview phase to adjust or redraw the mask if necessary by right-clicking the mask timeline and deleting it.

    3. Refine Mask

    Render Modes

    • Overlay Visualizes the extracted area with the background
    • Mask Visualizes only the extracted area.
    • To visualize the extracted area, choose Mask from the Render Mode options.

    Mask Formats

    • Bi: A hard edge mask. Binary values where 0 for background and 1 for the object. This is the default mask format.
    • Tri: A tri-leveled mask. 0 for background, 1 for the object, and 0.5 for the ambiguous area. Used for a soft edge refinement.
    • Full: A soft edge mask. Continuous values from 0 to 1.

    Refine Mask

    The Refine Mask process is used to generate soft edges, which are essential for accurately capturing fine details such as hair strands or motion blur.

    The refinement is guided by a trimap mask, where the model focuses on the uncertain regions to predict and generate smooth transitions. To ensure optimal results, follow the steps below:

    1. Convert to Trimap Format: Before initiating refinement, change the mask format to tri (trimap). This allows you to visually inspect the foreground, background, and uncertain regions across the entire frame.
    2. Review the Mask: Carefully examine the mask in trimap format to confirm that the uncertain areas are correctly positioned and that the segmentation quality is acceptable.
    3. Run Refine Mask: If the mask looks good, click the Refine Mask button to start the refinement process. The model will process the uncertain regions and generate soft edges accordingly.
    4. Inspect the Refined Mask: After refinement is complete, switch the mask format to full and set the render mode to mask. This allows you to visually inspect the final refined mask in detail.

    Refine Steps

    • Use Refine Mask to select areas of interest and click Refine.
    • To refine the mask, select the desired area in Refine Mask, then click the Refine button.

    • Finally, click the Play button to preview the video with the mask applied and ensure the area is correctly rotoscoped.

    Exporting Your Rotoscoped Video

    • Select the desired mask in the timeline.
    • Choose an export format (PNG sequence, GIF, TIFF).
    • Click Export and save your file.

    Resetting Your Project

    • To remove all effects and return to the original video, click Clean
    • This does not affect previously saved exports.
