YI Lite 4K Sports Action Camera not recording Proper PAL or NTSC frame rates, no 25 FPS no 29.97


.
In this video I show a huge problem with the Yi Lite Action Camera. The problem is that the Yi Lite does not record standard PAL or NTSC frame rates. Although its setup procedure includes the option to choose your video territory, PAL or NTSC, the Yi Lite does not actually record the frame rates for those countries.

When set to PAL and 25 FPS, the Yi Lite will record frame rates such as 24.98 FPS, which is not PAL or any other recognised frame rate standard. For 50 FPS it was recording 50.04 FPS.

For NTSC, where the two main frame rates are 29.97 FPS and 59.94 FPS. The Yi Lite is recording 30 FPS and 60 FPS respectfully, neither of which are NTSC frame rates.

It’s probably important to point out to anyone who uses NTSC frame rates. 30 FPS and 60 FPS are simply shorthand figures for the true frame rates of 29.97 FPS and 59.94 FPS.

Price: £389.99
Was: £399.99

The problem with all these frame rates recorded by the Yi Lite, is that everyone of them will lead to frame interpolation. Frame interpolation is when a set of frames or either extended or shrunk to fit a space. Depending on the interpolation method used by the NLE, edit software. This can show up as frames that jump, blurry picture, ghosting in the images etc. In any event, it’s all wrong.

I’d actually got the Yi Lite after a very disappointing experience with the Yi 4K+ and its very problematic external microphone recording system. Now I’m going to have to get in touch with Yi yet again, to arrange for another return which will hopefully not get my account into trouble with Amazon. It shouldn’t, as this issue, like the ones with the Yi 4K+, are all manufacturing, hardware and software faults.

Aside from the Yi 4K+ having serious audio hardware issues, it also records at an unacceptably low audio bit rate of 48kbps. This is even more shocking when you consider that the Yi 4K+ is their flagship action camera and their cheapest on their modern lineup, the Yi Lite, records its audio at 128kbps, just the same as the GoPro Hero 5 Black and Hero 6 Black.

Also in this video you will notice problems with the exposure stepping. What’s worse about this is that the Yi Lite was locked off on a tripod, the sky and sun were very constant and there was hardly any movement in the frame that could effect light levels and exposure.

Non of the issues I’m having are one off issues due to a single defective camera. I know this for sure as a lot of the issues are routed within the camera’s software and operating system and also their hardware interfacing. Bearing that in mind, I’m absolutely amazed by the fact that no one else seems to be picking up on all these problems with Yi’s 4K+ and Lite.

Hopefully, I’ll be posting videos of positive experiences with Yi action cameras and hopefully sooner rather than later.

Cheers,
Dave.
