Upload a video to Youtube without losing contrast I've been trying to upload a video to Youtube which had been created in Vegas Movie Studio HD 11 and rendered as an MP4 file. You may notice the text has become sharper and the watermark is now almost impossible to see:

The entire video is affected by not just the first slide. I have tried to increase the colour settings in Sony Vegas and with Youtube's built-in editor. I have also tried using the built-in Vegas Youtube uploader.

Video Properties


Created and rendered in Vegas Movie Studio HD. 
Rendered as HDV 720-25P (Matches project settings)
Audio: 384 Kbps, 48,000 Hz, 16 Bit, Stereo, MPEG
Video: 25 fps, 1280x720 Progressive, YUV, 18.3 Mbps
Pixel Aspect Ratio: 1.000
I worked out a satisfactory solution to this problem. It involves adding the 'Computer RGB to Studio RGB' Video FX to each video track in your Vegas Studio project. This effects the rendered file and project quite a lot but appears normal when uploaded to Youtube:

It's possible to disable the track Video FX whilst you work on your project so you don't have to deal with dimmed video. The effects will need to be be re-enabled before you render the project.
