Syntax

class UMovieSceneCaptureProtocolBase : public UObject

Remarks

A capture protocol responsible for dealing with captured frames using some custom method (writing out to disk, streaming, etc)

A typical process for capture consits of the following process: Setup -> [ Warm up -> [ Capture Frame ] ] -> Begin Finalize -> [ HasFinishedProcessing ] -> Finalize
