Hi
"I tried to open one, and Videopad 'converted' the project. Could someone tell me what Videopad is converting when it does that? I would think there wouldn't be anything so different that it would require conversion."
If you change to a later version of VP, the names and format of the constituent files that make up the .vpj project file as well as the file names in the will be different to those generated by an earlier version.
A later version of VP however, can load a project from an earlier version but will have to convert the files to the new format, and that is what you see happening.
However, a .vpj file created with the later version cannot be read by an earlier version, as the names of the files will not be known.
Even though a later version of VP can convert an earlier version .vpj file, in my experience the project formatting will not always be correct. (effects and transitions and even clip splits might be missing.)
Having converted the files to the later format, VP will then try to find the files on your PC. If they have been moved or renamed then the file path will not be correct and VP will inform you of this.
There will be an option to find the missing files on the (new) PC but I don't think you can change them en masse. This option has to be repeated for each file, even if you have placed them in the same folder, which is a bit of a pain.
Someone else may add to this hopefully.
