As to which one you need, it would be an experiment that you would need to determine the quality of each one that would suit your needs.

When you convert a file it doesn’t change or delete your original footage, rather it makes a new file for you to use.

Then you would need to ensure your Video Mode matches the same FPS as your video clips.

Typically you would set the Video Mode you want as step 1, then add source files. If your Video Mode is left in Automatic, the FPS is set to the first clip you used in the project, even though you may convert them later.
