No. You can leave the rendering page and Rotor will notify you in the top navigation when your video is ready - you can also check the progress there.
Our videos can take anywhere between 3-10 minutes to render - the length of the audio track and the amount of clips added will be a factor in the total rendering time.
If you like, you can start creating another video while your other videos are rendering. If you need to, you can leave the Rotor website and we’ll send you an email when your video is ready.
