Alexa Workflow in FCP X
ProRes has proven to be a high quality and robust video format that is widely used in the industry today. The capability of recording directly in Apple Prores format provides a shoot to edit option for the workflow of Alexa with FCP X. However, if you record video with Alexa in other format such as DNxHD or Rec. 709, the workflow will not be so smooth, since FCP X does not handle those videos very well. To fix this issue, you’d better transcode Alexa camera files to Final Cut Pro native compatible editing format- Apple Prores codec.
