The color rendering option is pretty good with all natural effects so that users can make lossless adjustments for color correction during post processing. The wide color range allows this camera unit to set deep colours for every shot.
It can deliver high definition videos with 1080p resolution settings whereas 4K has its own impression. Content appears with crisp details having well defined outlines. It is capable enough to manage changes between different color shades and ensures optimal white balance for all light exposures. On the other side, the audio quality is also satisfactory that makes your videos more stunning with impressive content delivery. The preferred recording format is Mov or .mp4 with codec support.
The only thing that doesn’t provide satisfactory performance for videos in SJ7 is stabilizer, which did not support 4K mode. However, it can deliver good results in light vibration carrying shots, or for handheld modes but lowers down its performance when connected to mounts in a running field.
When it comes to stills; you can make adjustments between 3M, 5M, 8.3M, 12M, 14M and 16M resolution to avail variable results as per requirements. Its 12MP sensor results all stills in JPEG format.
The touch screen provides easy access to camera shooting modes; you simply need to wipe up and you can access all camera modes with ease:
Photo Time Lapse: Allows impressive time lapse quality with numbers of individual shots.
Video Time Lapse: When you want time lapse setting for videos.

SJ7 is designed to offer rich content quality with its electronic image stabilization feature that handles all results smoothly during shaky shoots at high vibrations. The gyro sensor is combined with specially designed acceleration sensor so that all shakes and vibrations can be well stabilized at motion. Note that the image stabilization feature currently works only with 1080p resolution level and at 30fps and 60fps settings. It can deliver great results during handheld shoots but you will observe poor performance for extreme situations, especially when camera is mounted to capture a running field. But the fact is that this trouble is common in almost all action cameras that are designed using Ambarella Chipset.
SJ7 contains a 1000mAh battery inside that helps it to serve for longer time duration. Once you charge it fully, it can serve you up to 70 minutes when you are enjoying recording at 4K resolution level with 30 fps settings whereas service time gets reduced to 65 minutes when users switch to 60fps with 1080p. Note that, a dual charge safety feature is added to SJ7 battery with 2 special protection circuits so that overcharging damage can be avoided.
SJCAM SJ7 Star supports microSD cards up to 128 GB and Class 10 (U1) is recommended. If you often record in 4K resolution, then the U3 is recommended.
