Watermarks & Video Transitions

Any chance of having the option to add text watermark to our videos. One that can be adjusted by opacity.

Also, I have noticed that images aren't changed every 2 seconds when I choose that option when creating the AI Video. Possible to have the option to change images on AI Video. I created a fact based video about a cat as amyor in the USA and EVERY images was of a cat. Would have liked to have the chance to swap out for different image :)
