Transfer project from one application to another
There are ways to transfer projects between different video editing programs, but they are very limited. Take a look at my answer here; this question is about transfering projects between different versions of Premiere Pro, but the answer is basically the same. You can export a project as an Edit Decision List (EDL), however this will only contain the arrangement of the clips in the timeline (namely your edit decisions, hence the name), any effects, e.g. color-grading, will be lost. Another format that does basically the same is AAF. I'm not sure about the differences between both formats, but either way, most of your post-production efforts will be lost when transfering the project to a different program.

Also, this applies to prosumer-/production-level software. I'm not sure whether "low-end" software supports importing and exporting EDL-files. If I remember correctly, it's not possible with Premiere Elements; don't know about the Sony programs (you should be able to find that out over the developer's websites and/or Google).
