I have done this "rollover" in the constructor. I made the decision to rollover any timecode that goes beyond the 24 hour limit, because the timecodes I am used to using in media do the same. Do people agree with that assessment, or would you make it a method instead? Do my class properties (hours, minutes, seconds, frames) still satisfy the aforementioned statement? There is a small calculation in each, but it really is a very quick calculation. My basic understanding is that users of the class will view a property as little more than a field accessor, and therefore the implementation should be quick and clean and return as soon as possible. I often struggle to decide whether a class member should be a property or a method. The driving thought behind this decision was that it kept the class memory footprint much smaller, and I think calculations are much simpler this way. My fields are "totalFrames" and "frameRate", as opposed to a field for "hours", "minutes", "seconds", "frames", and "frameRate".

Private static int FramesPerDay(short framesPerSecond)Īlthough I've been doing software development for a couple of years, I still wrestle over what I feel are simple decisions when it comes to things like class design, so I'm hoping to ask a few questions about my class and hope that someone can re-assure or advise otherwise.

The "timecode" that I'm trying to represent is a timecode that is used in video editing quite often, and is seen displayed in the format "hh:mm:ss:ff", or 10:00:05:24, for example ("ff" = frames").
