I've been using HD Platinum v10 for 7 years and decided to get a better/faster computer and the latest version of Movie Studio. Can I open v10 projects in v14? Thanks.
Yes, they open in VMS 14 Platinum. As v.14 is 64-bit only and vs.10 (v.11.too). was still 32-bit only, note the following "Known issue" (from the Release notes).
"When using the 64-bit version of Movie Studio Platinum, 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 Platinum installations, performing editing as needed in 32-bit Movie Studio Platinum and finishing the project in 64-bit Movie Studio Platinum."
If/when you try v.14 be sure to get the Platinum version. Btw., this upgrade offer is again extended, now valid until Feb 20, 2018.
