Google has improved its Google Video service by enabling Mac support and in-browser video playback.

Other enhancements to the service include a larger and resizable viewing window, and more playback controls, such as pause, skip back, skip forward and volume. Also new is the availability of ten-second video previews that can be played on the search results page.

Google also announced that between Monday and Thursday of this week, visitors to Google Video will be able to view the series premiere of the UPN television network's "Everybody Hates Chris" show.

During those four days, Google Video will be the only place on the Web where the episode will be available in its entirety, Peter Chane, senior business product manager for Google Video, said. "We're working with all sorts of owners of video content to help them bring their content online," he said. "You'll see more high-quality video content on Google Video in months to come."

Google launched Google Video in January of this year. The service disappointed some because it didn't feature any actual videos to play back. What it did feature were transcript excerpts from TV, along with still photos from the video broadcasts, as well other complementary information about the programs. The indexed information also was limited to some television shows.

This lack of viewable content made it pale in comparison with existing multimedia search engines from competitors Blinkx, AOL and Yahoo. However, Google has been improving its video service. The company opened the service to allow anyone, from individual amateurs to television and movie producers, to submit video for inclusion in Google Video. It also made actual video viewable on the service.
