After doing a trial software, I have a few questions here.

1) How many images can be enhanced with Tier 1 (1500 credits)?
2) I have noticed that your app slightly changes the original image. How can I setup so that the result doesn't change the original image at all? I want to have the same image without being changed although it is only slightly. I have set creativity to 0 but it still has a different face than the original one.
3) How can I setup so that the image won't be upscaled at all? I want to have the same size.
4) Will you consider having video enhancement in the future? If so, will it be included for LTD Appsumo's users?
5) What is the function of Style Transfer?

Thanks.
