Bug scripting getFootageInterpretation -> setFootageInterpretation
This works in premiere pro 2019 and does no longer work in 2020:
Something changed in Object FootageInterpretation?
var interp = myFootage.getFootageInterpretation();
We were tracking this as DVAPR-4224879; it’s fixed in the current PPro beta, and will be fixed in our next official release.
