Sony Cyber-shot DSC-TX7

Sample PhotosVideo
It captures attractive 1080i high def video, although there is some slight distortion on wide angle settings.
Video Mode (16.25)
The TX7 is one of the new breed of compact cameras that captures high definition video. It can capture video with a maximum resolution of 1920 by 1080 pixels at 60 interlaced frames a second and a bit rate of either 17 or 9 Mbps, which is the same as last years camcorders (many of this years models have increased the bit rate to 24 Mbps, which produces better quality). The video files can be saved in either AVCHD or MPEG4 format (although the MPEG4 format limits the resolution to 1440 by 1080), both formats that are compatible with many video editing applications. Both will require conversion to upload to a video sharing service such as YouTube, though.
The 4x optical zoom can also be used while recording, but we did notice that the auto focus has a slight tendency to swim as you zoom, with the image getting slightly blurry while the camera is refocusing. We didn’t hear any noise from this zoom mechanism in the recording, though. The TX7 is also unusual in capturing stereo sound; most cameras just capture mono sound.
Video Color (5.49)
Although the TX7 captured good color in still images, the colors in videos were less appealing: our test chart showed overly saturated colors that looked a little garish. They were not as bad as many of the cameras that we test, but it was disappointing to see that the accurate color of stills wasn’t carried over to video. There is also no way to tweak this color within the camera: the only controls that you get are for the video quality, white balance and a self timer. More on how we test video color.
Video Sharpness (2.32)
We did find that the videos were pretty sharp, though; capturing video on the highest quality setting (AVCHD at 17Mbps) we saw a good amount of detail in the video and it looked smooth. More on how we test video sharpness.
