I just got an e-mail from my University IT security group, that they recommend everyone (at the university) to uninstall Apple QuickTime for Windows, since Apple Ends the Support,
The IT security group also recommend not to use the QuickTime Alternative (uninstallation is recommended), since it hasn't been updated since 2010.
How will this affect WATCHOUT?
Depends on the version, v6, not much at all.
WATCHOUT does not require Quicktime, since version 5.5.1
(in fact, WATCHPAX / WATCHPAX 2 do not include Quicktime).
In v5, .mov files containing h.264 or animation codec do not rely on QuickTime.
In v6, same h.264 and animation codec and also ProRes do not rely on QuickTime.
Of course, there are other codecs under Quicktime that will not work without Quicktime,
but those are the less popular ones.
I imagine a MacOS computer with Quicktime Pro would allow you to transcode
any .mov that will not work in WATCHOUT into a compatible codec.
WATCHOUT Production will completely lose its ability to Export a synopsis movie,
as that function does rely on Quicktime.
There has been talk of re-writing the export function to remove reliance on Quicktime altogether.
That one export function is reliant on QuickTime and that prevents WATCHOUT from evolving into a 64 bit program,
i.e. 32 bit is maintained to allow QuickTime encoding to be used.
