The Samsung NX10 features HD movies in 720p resolution with H.264 video compression which is also used by e.g. Youtube. There's also a HDMI interface to connect your camera directly to your HDTV. Three different sizes are available for recording:
1280x720 : High Quality up to 15min., Normal up to 22min
640x480 : High Quality up to 44min., Normal up to 66min
320x240 : High Quality up to 145min., Normal up to 210min
According to Samsung, the "NX10's APS-C size super large CMOS sensor offers not only detailed and clear video clips, but also allows target objects to stand out of the picture like in a motion picture." Well, we shouldn't overstretch reality but there's some truth in this statement - typical video cameras feature a very small sensor so a shallow depth-of-field is simply not possible here.
Taking videos with such a small camera feels slightly strange but the results are suitable and not comparable to the small, low quality movies from digital compact cameras. This applies also to the sound quality of the built-in microphone which captures low-noise mono audio. Single and continuous AF is available during recording although don't expect AF speed wonders here.
Here're two sample movies ... and yes, this is me on the board ...
