You can increase your animated video’s duration by going to the ‘download options’ page of your order. You can access your ‘download options’ page by going to your Order History then click download under your video.
In the ‘download options’ page, type your new video duration and hit enter. You can now choose to loop the animated video for the duration of the video, or you can click ‘slow down’ to slow down the animation speed of the video. The longer you set the video duration, the slower the animation will become. You can use this option to fine tune your video’s animation speed even more if the ‘speed’ option in the editor didn’t suffice.
