Stabilization
 RockSteady 3.0+
                Why it matters:
                A high resolution will give you crisp footage but also allow you to reframe your video without losing too much quality. A higher framerate (fps) will result in smoother video and is important when filming action scenes or fast moving subjects. Image stabilization is a crucial feature for an action camera, as it removes camera shake, vibrations, rotation and other movements that deteriorate your final footage.            
                Battery life
        The Action 4 offers a much larger battery capacity. The Action 4 has a removable battery whereas the Theta X's battery is not removable

                Why battery life matters:
                Nothing worse than running out of battery just before capturing the best footage of the day! A long battery life is reassuring and convenient when shooting footage outdoors where options to charge are limited. Even the use of a power bank can be tedious or simply impossible like when filming watersports. Having removable batteries allows battery swapping on the go which further extends your runtime.            
                Storage
        Only the Theta X features built-in storage. Both the Theta X and the Action 4 support SD cards.

                Why storage matters:
                High quality footage can quickly take up lots of space and insufficient storage can soon be frustrating. Having a large amount of storage and the possiblity to extend it or swap SD cards while on a outing will ensure you will always be able to capture the footage you want. However, smaller, wearable action cameras often rely on built-in storage because of their small size.            
                Weight and size
        The Action 4 is a lot more compact than the Theta X. The Action 4 weighs a little less than the Theta X.

                Why size and weight matter:
                Weight is important for action cameras because we often mount them on helmets, or hold them at the end of a selfie stick while moving. Therefore a heavier camera can be difficult or uncomfortable to film with. Weight is even more crucial for certain sports like road cycling or running.            
                Waterproofing and usage conditions
        The Action 4 is a lot more waterproof when using a diving case. The Action 4 beats the Theta X in high heat conditions.

                Why it matters:
                Most action cameras are waterproof for accidental splashing or use above water, but if you plan on Snorkeling or Scuba Diving, we recommend choosing a camera which offers a diving case and always using it for underwater footage. If you plan on filming Snowboarding, Skiing or other wintersports in extremely cold conditions, you should pick a camera that is rated for those temperatures, most cameras are only rated down to 14°F / -10°C. Many action cameras are prone to overheating, even in ordinary conditions, so if you plan on filming in hot environments, you should choose a camera that can function at high temperatures.            
                Camera and sensor technology
        The Theta X features a much higher resolution. The Action 4 has a slightly better video bit rate than the Theta X.

                Why it matters:
                A higher amount of pixels will offer better quality footage and higher resolution photos. A higher field of view means that the camera captures over a wider angle and therefore more action can be seen in the final footage. Some cameras require accessories to enable the maximum FOV. A higher bitrate at a similar resolution will offer higher quality video.            
                Camera settings
        The Action 4's 100-12800 ISO range is far superior to Theta X's. The Action 4's +/-4 exposure compensation is far superior.

                Why these settings matter:
                The ISO range and exposure compensation settings will mostly allow you to tweak your action camera for low light situations.
