hi all!
kevin is right. if you are unsure about how you have to deliver your final dpx output ask your lab.
and if you need log2lin conversion go with the 3dluts provided by arri on their website! worked for me during a small test with alexa and d21 material with logc basis.
the exact difference between the two luts you’ve mentioned would be interesting though. their names would suggest that one just cuts at the given boundaries and the other one scales the image down to fit in those boundaries. but when i tried it, i really couldnt see any difference on the scopes. only if i make a manual lut on the basis of one of the mentioned luts it seems to scale…
so far i ended up with not using them and staying in normal range mode, for the projects i have been working on so far all rendered out in pro res 422 hq and therefore is scaled automatically…
