Here's my honest review:

I like the features but the Zebracat team needs to make this better and here's how:

Captions: need more variations in the captions output.

Credit System FLAWS
I used up all my credits and only created 15 videos based on the selections I chose (voices and loop) and should have been given the ability to create atleast 30 (one per day). I created many shorts with the average length of 24 seconds, well the credit usage is too high and should be amended for shorter length videos and not deduct the same credits on a 24 sec video vs. 1 minute video.

Blurry Outputs
I have many final video projects that turned blurry and/or blur in and out, the resolution is awful and would like more credits to remake them. Please fix this issue so that future renders are not blurry.

Errors
Sometimes there are caption errors or output errors and we should be able to edit them but cant without rendering and using the credits all up.

Summary
I hope the team improves Zebracat with these changes because I see potential.
