Dorico Pro supports the use of videos within the program as well as the associated notations, such as markers and timecodes, and allows you to find appropriate tempos based on where important markers occur.
Videos in Dorico Pro are shown in a separate Video window and play back in sync with the music. Any existing audio in the video is also played back, and you can control the volume of this audio independently of the volume of the music.
Tip
You can use these features, including setting a project frame rate, without having a video attached.
