Why Was Drop Frame Timecode Created?

Why Was Drop Frame Timecode Created?
Since the NTSC standard had a peculiar frame rate, a special kind of timecode had to be invented so that editors would know how much real time had passed with a simple frame-labeling method. This is how Drop Frame Timecode was created.

.

Considering this, what is drop frame timecode?

Drop-frame timecode is a SMPTE standard that maintains time accuracy by eliminating the fractional difference between the 29.97 fps frame rate and the 30 fps numbering. When you use drop-frame timecode, Premiere 5. x adjusts the frame numbering so that an hour-long video has its last frame labeled 01:00:00:00.

Subsequently, question is, is 23.976 a drop frame? In other words, there is no standard for "23.976 time code". Without a standard, we have to use SMPTE 24 time code for both 24 fps video (where it syncs with the clock, like drop frame), and also for 23.976 fps video (where it doesn't sync with the clock, like non-drop frame).

Herein, should I Use Drop frame or Non Drop Frame?

Drop frame is a standard for broadcast networks using NTSC due to this correlation with real time. Non-drop timecode counts every single video frame and doesn't re-label any frame to account for the 29.97 fps. A program using non-drop timecode is approximately four seconds shorter per every hour.

Why is TV 29.97 frames per second?

North American television has a frame rate of 29.97fps because if you multiply that by the number of horizontal rows in each frame and then you multiply that by an integer, happens to be 286, you get out a whole number which matches exactly the frequency window this data is sent over.
