AE working color space / scaling

Question

Hi there.Original video used for test test:h264Color space                    : YUVChroma subsampling             : 4:2:0Bit depth                      : 8 bitsBT.709In After Effects, when the working space is set to REC709 (16-235) the overall signal is scaled down as shown in the waveform monitor.In Davinici Resolve the signal is scaled down when the full range is used insted to interpret the footage, just the opposite, which it makes more sense to me.Can anyone explain what is AE  doing with the signal when different working space is used? Best regards.

I have a question in the same region.In some Test with full and legal range footage in 422 and 444,we see, that a File have other interpretations on a scopein ADOBE Premiere than in ADOBE After Effects!Wy is the Video Output between this two ADOBE products not the same?I thay, that ist not professional.We get a spot from a customer in ProRes 422 in full range (i think, that ist not correkt !)But our After Effects Artist can not see this Problem, of course After Effects squeezes the picture from black to white into his workspace.Our Premiere Cutter see the mistacke after the import in Premiere directly.Hiere is on the scope the black under 0% or 0mv and the white is over 100% or 700mvI men the interpretation in Premiere ist ok and the After Effects interpration is very unprofessional.
