Does anyone know what the time line is for? When I look at the info of one of apples trailers or ads you get Codec: H.264, AAC, Timecode but when I prepare my short movie I dont get the Timecode?
I am trying to get as close to apples quality as I can, so any pointers would be great.
Time Code is a tool that helps to keep things in sync, but not a factor on quality.
Most part of the part is a requirement, but makes no much sense in a video for a web.
John have explained very well how to add it to your clips.
