What would your feature do ?

The generated videos are too grayish in their colors, possibly due to training on stock footage. To counter this withering out, it may be possible to add a sample image and provide a richer color palette. Even better if it's applied during the generation, so it will have an actual effect on the model's decision making process.

Proposed workflow

1. Go to one of the tabs
2. Press Enable color correction
3. Add a sample image
4. The color histogram is transferred to the video, even better if during the sampling
