CineTreak CT-B1 Reviews

Useless for broadcasting

By Nate
Rated 1 out of 5
Date: 2026-01-02

First, the build quality is that of a $20 product, not a $120 product. The Logo isn't even parallel with edges, it feels like there is a tiny little circuit board inside, and nothing else. Its good that it's lightweight, but it probably could have also been half the size and made of some kind of magnesium or aluminum for the $120 price range. There are no controls, and no interface to see what is going on other than 3 LEDs on the front. There is a severe lack of documentation to even know what the blinking lights mean.... I can overlook these problems of low build quality, except that the output image is completely un-usable for any kind of professional application. The output video stutters so bad you can't use it. It feels like a 10 fps output. I went back and forth with customer support from the manufacturer and they essentially made the excuse that the process of converting the UVC video feed to HDMI is complex and it is what it is. So.... I'm not sure what this product is supposed to be for if the output video is so un-usable. I recommend that if you're looking for something to convert your Pocket 3 UVC output to a usable HDMI output for any level of broadcasting, live vlogging, multi-cam recording or anything else, that you look at other products. This one is not going to help you at all. I will be returning mine....
