Hi, im having a major issue rendering projects. I am new to vegas but have been using it all week and have had awesome results. However, today when i render my final products, the first 5 seconds have wavy horizontal lines and the quality is very poor. Then after a little while the video quality is excellent!

I have been rendering the same clip for 2 hours trying every possible potential fix i can think of, but i cannot figure it out.

Anyone know whats goin on? also when i preview the clip before rendering everything is awesome quality, even the beginning....

Any help is greatly appreciated!
