I've been using Vegas Pro 14 for a while now, and have been able to make videos with transparent backgrounds due to the Quicktime 7 option for rendering. Lately, this option is no longer present, and I cannot find any recent postings with an explanation or a fix for this. I have uninstalled and reinstalled both Quicktime 7 and Vegas Pro 14, but the option is still missing. Was there a change that I missed, or should I use a different render option?
