No the quality will not be in the bad preview form that you see.
And to avoid bad previews you can either set it to preview (full).
then right click in the preview window and make sure that
Adjust size and quality for optimal playback is not selected.
As for the choppiness, if your computer isn’t powerful enough,
playing media (especially HD) will be choppy….but that don’t
have any effect on the finished product.
