I am currently using version 11 and am part of the way through editing a project. Can I safely upgrade to version 12? Will it read my project file from version 11 correctly?
Upgrading in the middle of a project may be a bit of a risk, even though the v11 (32-bit) projects should open correctly in v12 (32-bit). In v12 (64-bit) note this When using the 64-bit version of Movie Studio, third-party plug-ins will work only if they are 64-bit plug-ins. Please check with the plug-in vendor for available updates. You can share projects between 32- and 64-bit versions of Movie Studio installations, performing editing as needed in 32-bit Movie Studio and finishing the project in 64-bit Movie Studio..
If you take your project to v12, save it with a different name there. So you'll have the original project still available if for some reason you need to go back to v11.
