GoPro Hero 4 Ports and Connectivity: Audio, USB, HDMI
When we venture into the topic of ports and connectivity in GoPro cameras, you should expect to witness several input and output ports that offer versatile uses. The GoPro Hero 4 Black and Silver in particular offer a myriad of ports which can be used for audio and video purposes, as well as additional connectivity options which you can make excellent use of.
Luckily for you, the ports of the Hero 4 cameras are standardized, meaning that they are much easier to use than proprietary connections found in other action cams. Below we will look at the ports and connectivity options of the GoPro Hero 4 camera, in particular audio, USB and HDMI connections.
When it comes to the audio options of the Hero 4 cameras, you have an internal mono mic that you can use. Alternatively there is minute pinhole located on the right side of the GoPro Hero 4, which can be used as an external microphone if you would like to record audio along with your video.
An external stereo microphone can be attached via a 3.5mm input (adapter), which must be purchased separately as it does not come with the Hero 4 cameras.
While the Hero 4 Black and Silver are composed of many of the same audio options, the Hero 4 Black comes together with an integrated Analog to Digital Converter (ADC). This particular feature makes the GoPro camera compatible with a greater selection of professional and low sensitivity external microphones. This in turn leads to a more immersive audio experience, as audio capture is enhanced for optimum performance. So whether you are recording a jam session, voices or a live show, stereo audio capture will be defined.
Remember to check the compatibility list if you are looking to purchase an external mic for your GoPro Hero 4 Black.
- USB Port
The first port you will see on the GoPro Hero 4 cameras is the mini-USB port. There are 2 chief reasons that this port is used for. The first and most straightforward reason is to charge the battery of either the GoPro Hero 4 Black or Silver. Both of these cameras come with a mini-USB cable which works well with all USB outlets. However it is recommended that you use a 2 amp USB port (as found on an iPad or tablet), as regular amperage ports offer slower charging.
The second reason for using the mini-USB port on the GoPro camera is to transfer your captured photos and videos to a secondary device e.g. computer. This process is simple as the GoPro will appear as an imaging device on your computer or tablet, and thereafter you can begin your file transfers.
The third and less common use of the mini-USB port is as a connection for the 3.5mm mic input. This input cable acts as a medium for the transmission and consumption of non-digital video and audio to secondary devices e.g. a microphone.
The mini-USB port has also been found by some to have the ability connect directly to some remote viewing systems. Therefore you can transmit video to a First Person View system without using a HDMI cable.
The micro-HDMI port on the GoPro Hero 4 cameras allows you to play back photos and video directly on a TV via a HDMI cable. Because of the tiny nature of the GoPro HDMI port, a regular HDMI cable will not work and you will therefore need to purchase a micro HDMI cable.
You can also use the HDMI connection during production as well, if you fancy yourself to be a videographer.
Now you know all there is to know about the GoPro Hero 4 Black and Silver ports and connectivity capabilities.
