I have a request to deliver our short film in UHD 50Fps. Our original master is UHD @ 23.98.
Since we don't have the resources to go to a dub house and either access to a terranet.
What a re the chances to result successful a cross conversion in deviancy resolve, by dropping my 23.98 to a 50fps timeline and export a new master.
i suggest you drop the footage to a 50fps timeline, and then retime the clip back to its original length.
you can try few davinci's "retime process" options in the edit tab - "effects inspector" menu for best results considerig the frames interpolation
