How to Determine CODECs used by Camcorders Before Purchasing!

I'm looking for a new Action CAM & was recently alarmed by Stev's revelation that the GoPro Hero 6 Black uses the H.265 CODEC which is not supported by PE!

I use Premier Elements 14 on a WIN 7 PC.

My current Camcorder is a Panasonic V727  (uses AVCHD).

I also have a DJI Phanton 3 Standard which usued MPEG-4.

Both work fine with PE14.  I have also included video from a GoPro Hero 5 into my video.

I found a list of File Formats as supported by Premier Elements (15 to 10).

I'm not necessarily wanting to buy into the GoPro range as there are numerous other Action CAMs for occasional use.

But it seems difficult to find which CODEC each offering uses (so far only found that the Victure Action CAMs use H.264 which is OK).

I'd like to try to avoid buying a camera & then finding that the resulting video cannot be processed by PE14.

I've tried searching in Google with not much luck - any suggestions how to easily find which CODECs are used?

Or is H.265 so rare that only the latest GoPros use it?
