Recommend me a helmet cam.

I found at higher bitrates (like 16 MB/s on 1080p) H264 comes out more detailed than HEVC anyway. That sounds wrong when HEVC clearly wins at lower bitrates like 2 MB/s, but H264 starts to swap with it at the higher bitrates, with more detail. Since both are at 16 MB/s there's no file size increase using H264 in this case. The difference is only slight, but it's there.

I have been through the process of looking at cheaper alternatives and still ended up getting a GoPro.

No way are these things worth what they cost considering it's only a camera. Compare it to a smart phone, it's getting on for almost half the price of the latest iPhone and does 10% of what that smart phone does, if that.

That right there is the benefit of volume production. Make enough of them and they get cheap. GoPro and the like are a comparative tiny niche.

I can't find anything about it now and my recollection is a bit hazy, but I read years ago about the company that made the accelerometer they used in the Nintendo Wii controllers. The company that made them manufactured about 10 a month, and they cost ~$80,000 each. Nintendo came to them and asked how much if they guaranteed a minimum order of 1 million units a month. It came out to something less than $10 (I have $3 in my head but not sure). Scale makes things cheap!

I use a Dragon Touch Action Camera 4K HD 16MP via eBay, dirt cheap, the video is reasonable for the bargain price and the camera is as good as a smartphone. Also comes with numerous accessories including a remote which is really useful and with a cover that is waterproof. Obviously not as good quality as a GoPro or similar but more than good enough for what I use it for which is just recording my ride in general. It also comes with all the bells and whistles and sits comfortably on a helmet or handlebars.

It's interesting that a number of action cams from brands you have never heard of look like clones of previous gopro models. The sensors and processor chips used by Gopro are widely available and the cases plus various fixings are the same. Not sure about lenses though since they do not come from China and software and app for Gopro is developed in house. That software is quite advanced now including features like auto fix if a sd card error occurs. Battery technology is also far better now with the latest Gopro batteries. I can leave my hero 7 unused for weeks and very little battery discharge occurs during that time.

A GoPro 8 or the first DJI Action cam are great for the money. The DJI Action can be found quite cheap now after the new one came out. The new one is both expensive and unfortunately quite stupid.
If you don't buy the extension pack, the camera part only has internal battery and internal storage. And if you add an extension pack, the camera is no longer waterproof. I don't know what they were thinking......

Hmm. It's pretty lumpy around here. 2nd hand GP might be a way to
go.

Po!!

Anything after a gopro hero 7 is the go, get it 2nd hand and try to get a couple of batteries and a chest mount too as that is the best view, the stabilization is just fantastic and the sound is great too.

To add to my earlier post (and if was buying a new cam now it would be gopro 8)......for mtb the higher the mount you use, the worse the perspective becomes. Less impression of speed and changes in the level of the trail appear flatter. Chesty is by far the best option.....helmet mount the worst...apart from on the bars!
