Best way to deinterlace and double framerate

Hi all, newbie in video enhance, im curious about the best way to deinterlace, for example dvd 720x480 generally bottom field first…better flowframes, hybrid (very slow or placebo) and after put in topaz or make all the deinterlace in topaz?

And if double frame rate (from 29.97 to 59.94) sometimes there are glitch…but seem the smoother in unifab make a better job…

Depends on the source. If it’s a film that was interlaced, you need to drop it to 23.976fps or 24fps after deinterlacing it. There are a great many other types of sources that will need different considerations.
