Spinning zoom effect using stable diffusion via computerender.

1. Setup

You can install the python dependencies by running:

pip install -r requirements.txt

To install install ffmpeg: Linux

apt install ffmpeg

Macos:

brew install ffmpeg

Windows:
https://ffmpeg.org/download.html

2. API Key

You can get an API key by making an account at https://computerender.com/account.html To make your key visible to the python client, you can add it as an environment variable:

export CR_KEY=sk_your_key_here

Or alternatively provide it when initializing the client in the python script:

cr = Computerender("sk_your_key_here")

3. Running the script

It is a good idea to first create a short, trimmed version of your video that's just a few frames. This will be helpful for tuning parameters to get the right amount of modification to your video. Most importantly, the "strength" parameter will determine how much influence the effect has. The angle and zoom parameters control the speed of the zooming effect.

Run the script:

python spin-zoom.py

4. Post processing

To produce the final output, the video was imported into adobe premiere and slowed using "optical flow" as the frame interpolation. It may be possible to achieve the same effect using opencv, but that is not covered in this tutorial.
