What is A-B cut? And what is different from the trim function in the previous versions of PowerProducer?

In the 3.0 version of PowerProducer, the trim function allows you to keep the video portions in each clip as you want. In stead of keeping the wanted part, The A-B Cut option allows you to trim unwanted portions from the beginning and end of the clip. This enables you to specify and remove any unwanted section of video. You can easily cut the annoying TV commercials if you record some favorite programs from TV with PowerProducer.
