The way I do my edits are to adjust the luminance levels in my NLE, Sony Vegas Pro, using a video scope or similar tool to fall within the 16-235 (0-100 IRE) range. This outputs to broadcast (TV) levels when rendered. My camera tends to record with the black levels close to 16 but the white levels up to 255. It helps a great deal with highlight clipping. Adjusting Zebras on the camera to somewhere in the 95-105 IRE level would help minimizing clipping but my camera lacks the function.
