Is it just me or dose the chroma keying process degrade footage. I shoot with a dvx100a and have a decent greenscreen. My original footage looks great.After i render my composition the key looks good but my footage hes been degraded.What causes this?

When you "temp render" your footage, it only renders at half resolution, which will "look" like degraded footage, if you use the preview render button, or export it out it should look the same quality as the original.

You need to ensure that you have "High Quality Render" selected. To do this, go to the render menu and click render settings. Then ubder render engine make sure it says High Quality render and not Quick render.

Try using the Color Difference Key instead of Chroma Key.
