SJCAM SJ7 Star Drivers Download. Video quality of the SJCAM SJ7 Star. On the hardware side, the SJCAM SJ7 Star is well positioned, even if it can not keep up with the current market leaders of Sony, GoPro or YI Technology. The combination of Ambarella A12S75 image processor and Sony IMX117 image sensor allows the Action Cam to shoot natively in 4K at 30 frames-per-second. The recording format is MP4, encoded in H.264.
The video quality is hardly different from the ThiEYE T5e, which was tested just a few months ago. Video recordings convince with a pleasant sharpness, a high degree of detail and a natural color reproduction. Not convincing, however, the sound recording quality. Recorded in mono with a 128 kBit/s bitrate and a sampling rate of 48 kHz. Even without a waterproof case, the sound picked up by the action cam microphone is hard to use. The sound is clearly captured too quietly and is hardly understandable by the strong noise. Take the sound over that again SJCAM lavalier microphone gives you one of the best sound recording qualities an action cam has to offer.

An additional feature of the SJ7 Star is electronic image stabilization (EIS). However, this is only available up to a resolution of 1080p at 60 frames-per-second to choose from. The image stabilization provides acceptable results.
Photo quality of the SJCAM SJ7 Star
The maximum resolution for photos is interpolated 16 megapixels. Natively, the maximum resolution of the image sensor is 12 megapixels. The photo quality, like the video quality, convinces with a high degree of detail and a good color rendering. Despite the many setting options for exposure, the white balance or the ISO, the photo mode lacks the ability to digitally correct the lens curvature.
The capacity of the battery is 1000 mAh. The battery life measured in the test, with a resolution of 4K, was 60 minutes. Enabling additional WiFi, the runtime is reduced to about 45 minutes. The recording time at 1080p is about 75 minutes. The charging time is heavily dependent on the charger. Charging the battery directly on the action cam, the charging time is just under 3 hours. With the help of a special battery charger, the charging time can be reduced to about 1 ½ hours.
