Bests & Worsts Reviews from Amazon

I purchased this for a day trip to sea world with the hopes of getting some fun underwater pics and video of our child and friend. It worked well for the intended purpose, but there are a few "fine" points that I wish I had known before I ordered it. I hope this helps someone. I wanted an action cam with a Sony sensor, 16mp photos at minimum, and 4K/30. Here's what I found out... 1) the 4K bitrate is only around 10Mbps. Thats really low. It means that the 4K video will be blocky and lower-than-usuable quality. I also noticed frame skipping, so the 4K footage was mostly garbage. Keep in mind, a higher bit rate means that more information can be recorded per second. A GoPro Hero 5, for example, records 4K at 60Mbps. That's 6x more information per second. It makes a huge difference. 2) the bitrate for 2.7K goes UP to 20Mbps. I don't understand why, but it looks much better. The video is smooth with no noticeable dropped frames. Basically, this is the highest setting that you would want to use. 3) the bitrate for all 1080 and 720 combinations stayed at 20Mbps. For 1080, this is perfectly good for the average person. The audio is always 8K mono AAC (as are many action cams). I also purchased a JinSun camera on Prime Day so that I could compare. Im not about to try to sift through every action cam on Amazon, but I'd really like a higher bitrate recording than the Dragon Touch produced, especially at 2.7K (20Mbps 2.7K shows some artifactwing in faster action sequences). I prefer to shoot at 4K (I shoot Panasonic equipment professionally), but 2.7K is fine for my family stuff. Interestingly, the JinSun 4K/30 cam yielded an 18Mbps 4K (still low) and 2.7K-720p yield a 26Mbps file with 8K mono AAC audio. It does have a noticeably better picture quality. I contacted Dragon Touch about a firmware update to address the low bitrate and really didn't get much help. Interestingly, the emails came back from Akaso tech support, so I suppose this is just a rebranded Akaso. So, I'll keep the Dragon Touch for my 9yr old and the JinSun for myself. It's on par with other cams in this price range and at the asking price, a good value. For the asking price, I feel like the Dragon Touch is a little lacking and I'd look at the JinSun (on sale), instead. Both use the DVX app and have very similar features at similar prices. For the same money, I'll take the JinSun.
