Hi Martin,
Thanks for you post/reply. As we are updating our application, all times
are being stored in seconds (real number) and converted to and from
intervals as needed. Just like you in your application.
The old version of our application stored data in user document files.
In these files, some data was stored as only intervals, without a
timeScale to properly translate back to seconds for newer frameworks. I
was hoping there might be some rules I could apply to determine how
these interval (only) values could be converted to times without a
timescale value. In doing research and contacting LiveCode support, the
answer is: They can not (or at least not practically). The only way
would be to open the exact same media file in a helper app that is built
in an old version of LIveCode that uses Quicktime to get the original
Interval for each media file referenced in our user documents that needs
intervals converted. This is impractical as we can not expect the
installation of Quicktime under Windows any more and older LC helper app
will not run under macOS Catalina to name just a few of the obstacles.
The table of timescales in my original post is also distorted as many of
the media files are the exact same clip, just encoded in another format.
I am sure if I sampled a wider variety of clips I would see a much wider
range of timeScales.
Lastly, my inquiry was also looking to actually understand what
"intervals" really are, mostly out of curiosity and interest. I am
still curious as to what exactly "intervals" are. LC support just says
that they get them from the media frameworks and pass them along.
Thanks again for your reply.
