7. You may now have a look at the result in the waveform monitor to see if levels are satisfactory. Switch the Waveform monitor to IRE mode and Line mode.

Notice that the Chroma could be increased and the darkest sections of the luminance are not touching 0 IRE and the brightest sections are exceeding 100 IRE

 

8. Apply YUV curve filter and reduce the highest point a bit until nothing exceeds 100 IRE and create a gentle S curve until the darkest part touches O IRE at the same time the brightest part reduction is compensated (lifted) by the S bend

YUV curve

 

9. Apply the Color Balance Filter and increase the Chroma Level slightly until the level comes near the maximum allowed, this can be seen by the little rectangular boxes just outside the circle in case of HD, when editing SD, these boxes are just inside the circle.

The result should look like this on the Waveform Monitor
