Using Davinci Resolve 17.4.5 Build 7.
Universal QC, Amazon QC and Netflix QC have flagged blanking issues on three different projects and we can not figure out what is happening.
When applying the 2.39 blanking preset in 3840x2160, the output sizing blanking reads...
Top: 276.653
Bottom: 1883.200
QC says the measured lines are 276 x 1882 but they should be 277 x 1883.
So we type in those numbers to override the preset. Next QC report says it is now 277x1882. Fixed top but not bottom.
We are checking this before export and then after export and the video is always cut off by the blanking as expected. I have no other tool to measure the blanking in Davinci.
What is really weird is that when we incrementally change the blanking amount by decimal places (.200, .400,.600 etc), the visual blanking line does not change on the whole numbers. For instance from 1882 to 1883 the actual blanking edge does not move until we get to 1882.400. The blanking moves next at 1883.600
Why are we getting fractional readings even when typing in whole integers? It appears to be rounding down. Why would it not just count the lines? We can't display 2/10ths of a line.
QC is not playing nice about this. Any idea what is happening and how we can fix this?
