our fxplug effect produces quite a lot of intermediate data (about
150 kB per minute video) and needs to keep it somewhere between
closing and opening of a FCP project.
So far it saves this data into a file in the user space and keeps
the file name in a custom parameter.
Unfortunately, with this approach one gets into trouble, when the
user duplicates an effect instance. Then, both instances share the
same data file, and it happens that one effect instance falsely
loads the data that was created by the other instance.
I'm not aware of a way in fxplug to find out if an effect instance
was created by duplication.
As an alternative, I'm considering to put the whole data into the
custom parameter, but I'm concerned about possible side effects when
the FCP project file gets very big. However, according to my tests,
opening and saving an FCP project with 1 - 10 MB works quite well.
Any suggestions regarding the best strategy for handling big custom
data?
I don't anticipate that causing any problems. There are other
developers who store more data than that in their plugins, and which
get saved to disk. It's not ideal, but there are some situations where
there's no other way, and this is one of them.
