<p>
<strong>Usage:</strong> Our Gradio app is implemented based on our executable script CmdTrailBlazer in our github repository. Please see our general information below for a quick guidance, as well as the hints within the app widgets.
<ul>
<li><strong>Basic</strong>: Our app workflow is straightforward. First, select the Number of keyframes, then fill all the values in the appeared prompt/frame indice/bounding box(bbox) for each keyframe, as well as the word prompt indices. Finally, hit the Generate button to run the TrailBlazer. It is roughly 90secs to get the result. We also provide the <strong>SketchPadHelper</strong> to visually design our bbox format</li>
<li><strong>Advanced Options</strong>: We also offer some key parameters to adjust the synthesis result. Please see our paper for more information about the ablations.</li>
</ul>
For your initial use, it is advisable to select one of the examples provided below and attempt to swap the subject first (e.g., cat -> lion). Subsequently, define the keyframe with the associated bbox/frame/prompt. Please note that our current work is based on the ZeroScope (cerspense/zeroscope_v2_576w) model. Using prompts that are commonly recognized in the ZeroScope model context is recommended.
