What is the proposed idea/solution?

For film production, we need the ability to sum durations that are 24 frames per second. 

HOURS:MINUTES:SECONDS:FRAMES

With the current 00:00:00 format, it does not calculate accurately. 

...

How does is solve the user problems?

With the current duration formatting we can come close, but not be exact when summing TRT from multiple fields. A timecode format would allow accurate calculations. 

...

How was this validated?

Currently there's no way to tell AT that after 24 frames it's a new second.

...

Who is the target audience?

film production and editorial users
