I bought Rocketium on another deals website last year and it's great for personal use!
It's nice and easy to design individual slides.

There are some improvements I would suggest to make it a 5 taco bananza!
1. The transitions between slides. I found them very cartoony and only one struck me as professional. More transitions need to be added with professional videos in mind.

2. The 24 hour limit for edits to each video. Creating a video can take days or even weeks of back and forth with clients. The 24 limit will eat through the 30 video limit unnecessarily. Increase this this time limit to 1 week or increase the number of videos.

3. Optional: the ability to add multiple logos. The amount of times I've had clients who want 2 logos in their video has been ridiculous! The 1 logo insert should be increased as this has caused me to revert back to fimora and to manually insert an additional logo....which defeats the convenience of Rocketium.

4. Add the functionality of Clipman. Clipman's ease of selecting 4 images to instantly create a video was amazing! However, the images were rarely sized correctly and it proved more time consuming. If Rocketium adopted this style with it's preview of how the slides would look....it would easily be one of the top video software companies out there to launch straight forward videos! :-)

5. The pricing system. It was very confusing to have bought a lifetime deal and then inside the software be shown premium features I could not access. It felt like an indirect upsell and some of these "premium" features seemed like standard features for most other video software companies.

Overall, Rocketium is amazing and it's great to see you have made it to Appsumo! I haven't used it recently but now I'm confident this company is here to stay and I hope you keep innovating. You guys Rock! :-)
