The CogVideoX model is designed to generate high-quality videos based on detailed and highly descriptive prompts.
|
||||
The model performs best when provided with refined, granular prompts, which enhance the quality of video generation.
|
||||
This script is designed to assist with transforming simple user inputs into detailed prompts suitable for CogVideoX.
|
||||
It can handle both text-to-video (t2v) and image-to-video (i2v) conversions.
|
||||
|
||||
The CogVideoX model is pre-trained and fine-tuned using longer and more detailed prompts.Therefore, it requires highly granular and detailed prompts as input.This script aims to transform user inputs into executable inputs for CogVideoX, enabling superior video generation.
|
||||
- For text-to-video, simply provide the prompt.
|
||||
- For image-to-video, provide the path to the image file and an optional user input.
|
||||
The image will be encoded and sent as part of the request to Azure OpenAI.
|
||||
|
||||
This step is not mandatory; the model will still function correctly and without errors even if the prompts are not refined using this script. However, we strongly recommend using it to ensure the generation of high-quality videos.
|
||||
### How to run:
|
||||
Run the script for **text-to-video**:
|
||||
$ python convert_demo.py --prompt "A girl riding a bike." --type "t2v"
|
||||
|
||||
Note:
|
||||
Please set the OPENAI_API_KEY and OPENAI_BASE_URL(if needed) environment variable to your OpenAI API key before running this script.
|
||||
|
||||
Run the script:
|
||||
$ python convert_demo.py --prompt "A girl ridding a bike." # Using with OpenAI's API
|
||||
Run the script for **image-to-video**:
|
||||
$ python convert_demo.py --prompt "the cat is running" --type "i2v" --image_path "/path/to/your/image.jpg"
