Except for video editors, the HH:MM:SS:FF format is completely
irrelevant. Just think seconds. What the time code does is to
define a relation between a transport position in seconds and a
particular sample. Once you have this mapping, the format of
the timecode does not matter at all.
wrong scenario. suppose i want to store the point in
time where (say)
a zero crossing happens. SMPTE will not allow me to do that. i have to
store it as a sample position.
Again, why use the HH:MM:SS:FF format ? If you divide the 'sample
position' by the sample rate, you get a time in seconds. Conversely,
given a time in seconds, you can find the sample. This has nothing to
do with SMPTE or any other particular time code format.
