This short video shows you how to create a freeze frame from source footage in Forscene
Transcription of the video:
To create a freeze frame, select the frame that you want to freeze, mark an in point, move 1 frame forward, and mark the out point so that your selection’s duration is 1 frame. Next, mark the desired duration of the freeze frame with in and out points in the record window or on your timeline.
Freeze frames seldom include audio, so deselect audio on the patch panel and then drag your clip from the play window to the record window. Your freeze frame will then appear in the record timeline as a duplicated clip.
Blackbird is best-of-breed
