Do not get the hero Max.
The fact that it drops stabilization once it reaches the end of the first chapter (8mins or so) is a deal breaker.
Gopro breaks up the recording into chapters that are a set length (not sure why).
The issue is that if you have a race that is 20mins long, that is 3 chapters. For example:
010001
010002
010003
However, the stabilization does not continue when you reach the end of chapter 1, chapters 2 and 3 will be wobbly and unusable.
This can be mitigated somewhat by downloading GoPro labs and using the “large chapter” option that increases it to about 12mins per chapter. But, still, not enough.
Go to 12:20
Chapter size varies as a function of resolution I think.
