A) I have one 2.5K stabilised video clip available in the samples - HOWEVER....If you want to see another video review of this camera - then this one is very good https://www.youtube.com/watch?v=IH-JrsWxmx4 It also shows the other resolutions I didn't test in my video and demonstrates the image stabilisation. I would always recommend watching more than one review before spending this amount of money on a camera. Q) Would stabilisation remove the vibrations you get when you mount a camera on a bike's handlebars A) No - I've used the best in-camera stabilisation (on the Sony Action cams)- and it can't fix this problem. Handlebar vibrations are too quick and too severe. Q) Can it record and charge at the same time? A) Yes - this is a standard feature for all action cams I've tested. Q Can the screen be turned off during recording. A) Yes. Q) Does the camera get hot? A) No. Q) How did I mount the camera to my pocket? A) Watch this video https://www.youtube.com/watch?v=2O9aLYSntTQ Q) Can you record and stream over wifi at the same time? A) Yes (this is pretty much a standard feature for wifi connected cameras)...but as you can see in the video, there is significant lag. Q) Can you output over HDMI/Composite? A) I don't have the appropriate cables, however it says that you can "Preview and play back videos and photos on your TV via the optional cable". on the Specifications page here: http://yitechnology.com/actioncamera/specs/id/5.html Q) Battery Life in other modes A) Roughly the same as in 4K - e.g. 1080p60, WiFi off, Screen Off - battery life = 2hrs 2mins Q) - More like a weird situation I seem to be in where a number of people insist on 'informing' me that to digitally stabilise 4K video you would need a sensor larger than 4K.... A) I know, here is a video from a while ago where I talk about image stabilisation https://www.youtube.com/watch?v=eNZ6bg9uk0k A FEW COMMON FEATURES ON ACTION CAMS EVERY HD ACTION CAMERA I'VE EVER TESTED - will charge off USB, will power and record at the same time, charges over USB, charges from a standard 5V 2.1amp USB power supply, can be powered from a USB battery power pack....this is standard. -----AFFLIATED LINKS/ADVERTISING NOTICE------ All links are Affiliated where possible.
