# SketchVideo: sketch-based video generation and editing
![row01](teaser.jpg)
<!-- Provide a quick summary of what the model is/does. -->

SketchVideo aims to achieve sketch-based spatial and motion control for video generation, and supports fine-grained editing of real or synthetic videos.

## Model Details

### Model Description

<!-- Provide a longer summary of what this model is. -->

SketchVideo achieves sketch-based video clip generation (~6 seconds, 8 fps) based on text prompts, one or two keyframe sketches (at arbitrary time point). 

SketchVideo also achieves sketch-based editing for video clips (~6 seconds, 8 fps) with the same inputs. 

This model was trained to generate 49 video frames at a resolution of 720x480 given a context frame of the same resolution.


- **Model type:** Video Diffusion Model
- **Finetuned from model:** CogVideo-2b (720x480)

### Model Sources

<!-- Address questions around how the model is intended to be used, including the foreseeable users of the model and those affected by the model. -->

<!-- ### Direct Use

We develop this repository for RESEARCH purposes, so it can only be used for personal/research/non-commercial purposes. -->



## Limitations

<!-- This section is meant to convey both technical and sociotechnical limitations. -->
- The generated videos are relatively short (6 seconds, FPS=8).
- For two keyframe sketches, they should have consistent content.
