Hello to all I am new here.I have some query here.My friend is an editor working on FCP.He edit videos for broadcasting .I want to explain you the whole process. He gets a DG beta from a client.He grabs it on an FCP in MOV format.The size of the file becomes a massive 250GB.He edits it in FCP. Sticks the subtitles.then send it for a QC to the client.Client sugest some correction. He make the correction again on the 250GB file.then render it than make a DGbeta and sends the file again to the client. Is it necessary to work on that much big file? When i argue with him he says he has to maintain the broadcast quality so he has to do on this big file. Due to this he needs large storage space on the system and RAM. But i think that this could be achieved working on a small file as well. Can anyone suggest me sonething.
