I am using Sony Vegas 14.0 on my Toshiba laptop and find I am unable to render some mp4 clips I have put together from my mobile phone. The Render As window is not showing as many options in the Template list as on all previous occasions (and yes, I have enlarged the window but there are no more options to scroll down to) and, no matter which option I select, the Render button remains greyed out. I have used clips from my phone in previous projects and did not have this problem. Selecting the 'Real Time Render' function just produces an audio file. I have run out of ideas - does anyone have any more I could try?
