Mobiletechworld have tested the HTC Titan HD video recording vs the last Windows Phone 7 champ, the Samsung Omnia 7.
They note the HTC Titan records at a higher frame rate and with lower compression, resulting in a video stream that 10 Mb/s for the HTC Titan and 6 Mb/sec for the Samsung Omnia 7.
The boost in quality can be seen clearly in the above video while the Samsung Omnia 7 clearly has a lower frame rate and the video shows much less detail. Of note also however is the slower response of the HTC Titan to changing light conditions.
