Pixteller has very good animated designs that attracted me to buy; however, it takes time to render a 40seconds video.

I have used an existing video cover template (16:9), which I just edited the text, replace the background images and added 1 page. I have waited for more than an hour, and the rendering stopped at 22%, then the progress bar stopped and the countdown timer disappeared.

I have tried again, still the same. I have a 100MBPS internet and a gaming laptop with better RAM and processor. This is to conclude that my device and connection is not the problem, but Pixteller.
