Ever since I started editing videos with Sony Vegas movie Studio HD I would constantly come across a problem I could only know about when I finished rendering my videos: I saw nothing but a black screen.
The audio was fine, but no images were to be seen.
This honestly drove me crazy and discouraged me to make more videos until a couple of weeks ago when I decided to search on the internet for an answer and I luckily came across this post from http://envanna.wordpress.com that has and will be saving me a lot of time and headaches.

Thanks to vannade for letting me post this.
Have a good day!
