I'd like to suggest the addition of time effects as something to look into for future versions of the software. Specifically, I'm thinking of these effects being applied to the video, not the playback.
For example, adding a slow-motion section to emphasize the drama of a situation, or providing a sped up section for transitioning the video.
Another feature that would be nice is the trailing effect, where there are multiple echos of the motion. The front image being the most focused and it fades with each successive image. This provides a unique way to present action related images.
Thanks in advance for looking through this. If there are questions as to the specifics of these suggestions, I can show examples that have been made by others with different software.
