after purchasing VP 22 suite I am disappointed that I cannot use my older transitions because it says - UNREGISTER - where can I find Sam Kolder style transitions?
You would need to check with the creators of the Sam Kolder style transitions that you have to make sure that Vegas Pro 22 is a compatible host for those transitions. A basic Google search shows that Sam Kolder style transitions seem to be for Premiere Pro/After Effects.
Have your "unregistered" transitions worked in previous Vegas Pro versions? If yes, which version/s of Vegas Pro? And if the "unregistered" transitions are a different package to the Sam Kolder package, what is that other transition package (e.g. company name and package name)?
Those are custom transitions for BorisFX's Sapphire. Do you have a current, licenced version of Sapphire installed? If not then the transitions won't work.
I'm not sure whether or not this widens the 3rd party options to include Universe (now under the Maxon umbrella and who from 1 April this year have dropped Red Giant support for Vegas Pro in new releases) and WINRAR.
Yeeees Boris FX - I thought that in MV22 suite it is already... - I can do it now - thank you I'm shooting with a new camera 10bit flat mode + then LUT but as I see rendering in MV22 you can only do 10bit in HDR or HLG - does that make sense then?
The important thing is for the flat to REC 709 conversion to be done at high precision- so in project settings 32-bit full with view transform off. If you're not rendering to HDR or planning to do further editing of the files an 8-bit file for viewing is adequate.
