The fastest way to do it is to select all objects in the timeline, right click over one of them and click "save objects as takes". This will work as long as you plan to use them in other projects that you will create in Vido Pro X.
As George has suggested but not sure if this saves with all the applied effects etc., - Otherwise use File > Batch conversion and follow the prompts. All the edited clips in Track 1 will be save as individual files in a folder of choice and can be used in another program or project.
