Final Cut Pro X, the latest video editing software release of what Apple calls is the biggest advance in Pro video editing since the original Final Cut Pro, has reportedly irked professional video editors.

Editors have complained that the latest release does not support old projects created in earlier versions of the software, including the most recent, Final Cut Pro 7. They also say that FCPX does not take footage from a tape deck, and only imports files from digital media.

Some editors have gone ahead and vented their anger in an online petition against the new release. In response, Apple has reportedly offered refunds to customers, and has also released a FAQ to clear misconceptions about the product.

However, in the FAQ, Apple said that the design of the new product does not allow it to open old projects without losing data.

The company added that it will add a multicam support to the software in the future.

Last week, Apple released the latest version of its video editing software, Final Cut Pro X.

It said that completely rebuilt from the ground up, Final Cut Pro X takes full advantage of the latest Mac hardware and software.

Among the new features in the latest version of what Apple calls "the world’s most popular Pro video editing software" is a ‘magnetic’ timeline, content auto-analysis and background rendering.

Final Cut Pro X also features background rendering, and offers Clip Connections, a tool to link primary story clips to other elements.

Apple Worldwide Product Marketing senior vice-president Philip Schiller had said that Final Cut Pro X is the biggest advance in Pro video editing since the original Final Cut Pro.

"We have shown it to many of the world’s best Pro editors, and their jaws have dropped," Schiller had said.
