I cannot see the point of paying for this to take over 12 hours to render a video and taking another 12 hours to render it again before I can export it. What a load of tosh. I can get the same results in half the time completely free without paying for this rubbish. There is no help, no support and the guides are useless. They do not even cover this part of it. Theres probably a reason for that.
Thanks for writing in. Are you getting any error or message? Could you provide the details of the media you're using (codec/ format, frame rate, frame size)? You can use MediaInfo to get details of the media: https://mediaarea.net/en/MediaInfo/Download
