What is best video editing software to make professional videos?

As much as what you say is true, Jill, you still want flexibility.

So, if you want to spread your "editing wings";

- On a Mac, get Final Cut Pro - there is no better option in existence
- On a PC get Edius - there is no better option in existence

Adobe Premiere is only popular because of Adobe's name. Unless they have made significant improvements over the past couple of years, you will find it significantly harder to work with. Especially if you do a lot of composites.

Depends on exactly what you want to do with it, your budget, and how much of a learning curve you want to deal with.

For doing mainly screen capture vids, Camtasia and Adobe Captivate are the best paid options. CamStudio and Wink are popular free options.

For traditional editing / post production...

Sony Vegas - relatively easy learning curve, but still plenty powerful. Their "lite" versions have more than enough features for the average user, and are much cheaper than the pro version.

Final Cut (Mac only) - BIG learning curve, and expensive. Industry-standard program with every bell and whistle imaginable, but definitely overkill for the average user.

Edius - Like FC, an expensive, high-end editor with a big learning curve (but for PC). They have a "lite" version too, but I haven't used it.

Lightworks - By far the best free video editor, if you don't mind the "unusual" interface (it has a MUCH different layout than most video editors). So a bit of a learning curve there. But that aside, a very powerful program.

Hope that helps!
