I'm using Sony Movie Studio Platinum 12 and Ive just come across a strange issue that I haven't encountered before. I went to render just now but Movie Studio only creates a portion of the project that I was working on. It's not using all the content that is on the timeline. The video project runs for about a minute within Sony Movie Studio but the finished video file runs for less than half of that. It skips out the beginning as well as the middle and everything after that. Any theories as to what's causing this?
Most likely, "the reason why this has happened is because a setting in the RENDER AS window has been selected by accident. All you have to do to fix this, is de-select Render Loop Region Only." (from Dr Zen)
