• If you see graph Editor, replace it with Properties window (with "drop-up button")

Properties

Dimensions

• Check the Resolution
• Check the Frame rate. E..g. 30fps for youtube (should match the source video).

• Set File format (e.g. H.264 or Xvid)
• Select RGB (for color)

Encoding

• Set preset to the same video format
• Bitrate: 6000 is ok

System settings

Open: Menu -> File -> User Preferences -> System
