A:AnswerTo extend your recording time, the easiest option is to bring along extra batteries. If you want to extend the recording time on a continuous recording though, you could use an external power supply like a power pack to provide power that is run directly into the GoPro's USB-C port. The HERO8 can be mounted on a bike. The most common setup for this is use the GoPro Handlebar Mount. Other options other bikers like is to wear a Chesty mount or to use a helmet mount like the GoPro Vented Helmet Strap Mount.
A:AnswerYes, you should be able to. Videos shot on a GoPro are saved as mp4 files, which can be imported into most video editing programs, including iMovie on your Mac.
A:AnswerWhen used with the Media Mod, you can output an HDMI signal. If your switcher is able to accept an HDMI input, then you should be able to connect the HERO8 Black with your system.
A:AnswerBattery life depends on the settings you use. At the highest frame rates and resolutions, a full charge will get you about 45 minutes of recording time. At lower resolutions, you should get about an hour and twenty minutes. And, you can also use an external power supply if you'd like to have even longer recording times.
A:AnswerYes, there is an option to turn on a photo timer with the HERO8 Black. Plus you can control this camera using your voice to take a photo simply by saying "GoPro take a photo".
