MEASURING VIDEO TIME IN ADOBE PREMIERE
Measuring Video Time
Correct synchronization is necessary to work in video, so it is also necessary to measure time using numbers. Your familiar time-division hours, minutes, and seconds are not considered sufficiently accurate for video editing, as a single second may involve a lot of events.
You can determine how time is divided in your project by determining the project time base. For example, a time base of 30 means that every second is divided into 30 units. The exact time when the edit takes place depends on the time base you have fixed because an edit can only be possible on one-time division, using different time bases, time divisions come to different places.
The time division in a source clip is determined by the source frame rate. For example, when you shoot a source clip using a video camera with a frame rate of 30 frames per second, the camera records the scene in 1/30 of every second.
After this, the measurements determine how often the premiere prepares the frames from your project by determining the project frame rate. For example, a frame rate of 30 frames per second means that the premiere will create 30 frames out of every second of your project.
Counting time with time code
The time code defines how frames are counted and this affects the way you view and determine the time throughout your project. Time is always the time base or frame rate of a clip or project. Does not change, it only changes the way the frame is numbered.
You determine the time code style based on the media that is most appropriate for your project. For example, you count frames in a way when you are doing video editing for television and when you are editing motion picture film, then this method is different from that.
