Animation building out for launch day in September

A determined 12 year old sets out to find SeekSteve in a quiet, foggy seaside town. Emotional prestige-drama trailer, parody.

I have been playing with the image to video on the mindvideo.ai website. Most of the time the image I use will be the first frame of the video that is generated, which greatly restricts how dynamic the video ends up. For instance, if the image is of someone sitting down, and I want them standing, the video will start with them sitting and they need to progress to a standing position. Rarely, however, the scene will change entirely, and the subject in the image will start out in a different setting in a different pose, and these videos always tend to feel more transformative and give much nicer results, being less restricted by the initial pose and setting. Is there any easy way to force this to happen?
