When the CldVideoPlayer loads, the initial player size may be different from the videos if it is not 16:9, which is in the case at a minimum for some of the demo videos we use.

To fix this, we can define a width, height, and aspectRatio on the player initialization config:

        width,
        height,
        aspectRatio: `${width}:${height}`,

Which can be taken straight from the props.

When updating this, you'll need to update the @cloudinary-util/types package to at least 1.0.2 to pull in i think just the aspectRatio.
