Power Director is a very basic Video software, as is Nero. If you would like to know user preferences for softwares, check out sites such as www.videoguys.com, or www.videohelp.com. There are varying opinions of what is good. Many people believe that something is good, because that is what they use, and they don’t know that better programs exist.
Everything boils down to what is your source, and what do you want to end up with. If you are capturing as DV-AVI, Adobe Premiere, is actually a very good software. If you are capturing as MPEG, it isn’t so good. If you are working with MPEG video, check out the tools at www.videohelp.com. Most folks there, like Womble Mpeg software, but there are others which are good. In my opinion, and the opinion of many of my fellow video editing buffs, Power Director is substandard… But if someone has it, and likes how it works, good for them…
