VIDEO. The Vivitar DVR914 4K takes good video, at a quality like nearly all Action camcorders. Pictures were a bit soft, which means it will be difficult to make out tiny details and very subtle patterns in the image. In low-light situations, the video was only fair: fairly dim, soft and grainy. It captures Ultra HD video at 3840x2160 at 10 frames per second (fps), progressive-scan (p). For a more reasonable frame rate (for less motion blur), it can be set to 1920x1440 at 30p fps. It has an above-normal frame-rate mode 1280x720 at 120 fps.
AUDIO. It captures good audio in mono, better than most.
PHOTO QUALITY. In Photo mode, it captures at best 16-megapixel stills with poor quality.
LENS. The lens has a fixed focal length; it has no zoom capability.
IMAGE STABILIZER. Shooting in well-lit scenes, this model did an excellent job of minimizing the effects of camcorder shake.
ADDITIONAL COMMENTS. It survived our repeated-drop test. This model is about average in size and much lighter than the average action camcorder.
