Comparison Akaso V50 Pro vs Akaso V50 X

The degree of dust and water protection of the protective case supplied with the camera.

Protected case will save your camera from dust, water, temperature changes, shocks, etc. The specific degree of protection is indicated according to the international IP (Ingress Protection Rating) system, according to which each device is assigned a code of the form IPXX, where X is replaced by specific numbers. The first of them characterizes the protection against the penetration of foreign objects (from 0 to 6, where 0 is no protection). Usually, in boxes for action cameras, this indicator does not go below 5, because otherwise the container would have too large gaps, and its use simply would not make sense. Level 5 provides dust resistance — dust can get inside the case, but in small quantities that do not affect the device inside. Level 6 corresponds to complete imperviousness to dust.

The second digit is protection against liquid ingress (from 0 to 8, where 0 is no protection). Usually, the minimum level of protection against water is 6.

6 — protection against short-term immersion (for example, falling into a sea wave);
7 — protection against temporary immersion under water (up to 30 minutes) to a shallow depth (up to 1 metre), without continuous operation in immersed mode;
8 — protection against immersion to a depth of more than 1 metre for a time of more than 30 m, with the possibility of continuous...operation underwater. The specific level of protection of level 8 can be quite impressive — up to the possibility of diving to several tens of metres.

Note that protective cases for action cameras can be sold separately. Therefore, if the capabilities of the complete container do not suit you, there may be a more secure case on the market. On the other hand, in general, it is still more convenient to buy such an accessory immediately with a camera — so as not to waste time and effort on choosing the right protective case.

The ability of the camera to record HD video (720p).

The official HD specification provides a resolution of 1280x720. However, in action cameras, there may be resolutions slightly different from this parameter, for example, 1080x720 or 1440x960. Anyway, HD is the most modest of today's high-definition standards, which, nevertheless, provides a fairly clear and detailed image.

Another important parameter given in this paragraph is the frame rate. The higher it is, the smoother the movement in the frame will be, and the details in dynamic scenes will be visible clearly. Technically, 30 fps or even less is enough for video, but 60 fps is considered the perfect value — at this frame rate, motion blur becomes almost imperceptible and at the same time the size of the captured files remains within reasonable limits. However, there are cameras on the market with higher frame rates at HD resolutions — 100 fps, 120 fps, 200 fps and even 240 fps. This speed is usually used for recording slow-motion video, but such a possibility needs to be specified separately.

The ability of the camera to shoot QuadHD video.

This standard includes an extensive set of resolutions — from 1440 to 3456 pixels horizontally and from 1440 to 2160 pixels vertically, with almost two dozen intermediate options. It is a rather specific transitional option between the relatively inexpensive FullHD 1080p and the demanding UltraHD 4K, allowing you to shoot higher resolution video than 1080p without significantly increasing the cost of equipment. Note that pure QuadHD resolutions are rare in TVs and monitors, but modern technologies make it possible to comfortably watch videos of this format on any high-resolution screen.

Another important parameter given in this paragraph is the frame rate. The higher it is, the smoother the movement in the frame will be, and the details in dynamic scenes will be visible clearly. For example, a filming speed of 25 fps or 30 fps approximates the standard frame rate in film and television; such an image is quite viewable, but fast-moving objects in the frame will look blurry. With an increase in speed to 60 fps, this effect becomes almost imperceptible. The highest QuadHD frame rate found in modern action cameras is 120 fps; this frequency is used when shooting slow-motion video (as well as models with a frequency of 100 fps) because at a n...ormal playback speed, 60 fps is enough.

The ability of the camera to shoot Ultra HD 4K video.

This format covers several resolutions in which the horizontal frame size is approximately 4K pixels. The most popular in action cameras is 3840x2160 (twice the FullHD frame on each side), but there are other options — for example, 3840x1920, corresponding to an aspect ratio of 2:1. In general, 4K is a kind of successor to Full HD: among HD standards that surpass Full HD, UltraHD is the most popular, in particular, many advanced TVs are produced with 3840x2160 screens. On the other hand, this format is quite demanding in terms of processing power and memory, so it is relatively rare in action cameras, mainly among premium models.

Another important parameter given in this paragraph is the frame rate. The higher it is, the smoother the movement in the frame will be, and the details in dynamic scenes will be visible clearly. However, in UltraHD mode, most modern action cameras produce a very low frame rate — most often 30 fps, and in some models 24 fps or even 15 fps. This video is quite viewable, but fast movement in the frame may look blurry. There are cameras capable of shooting UltraHD at a solid speed of 60 fps — the blurring effect during such shooting is almost imperceptible. However, such a model cost is high.

Frame rate supported by the camera when shooting in slow motion.

In general, such shooting is called “high-speed” because it is carried out at an increased frame rate (more than 60 fps). As a result, when played back at normal speed (60 fps and below), the video looks slow hence the name. This kind of slow-motion can be used just for fun, as an artistic technique, and even for scientific purposes — to capture movement that is too fast for the human eye. In any case, the higher the slow-mo frame rate, the more you can slow down the video and the more advanced the camera is in this regard. On the other hand, the higher the frame rate, the more performant the graphics part should be; and this, in turn, affects the price of the device, sometimes quite noticeably.

We also note that slow-mo shooting may be available only at certain resolutions, not always at maximum. These points can be directly specified in the specs of the action camera.

Additional information regarding the sensor installed in the lens. This item can specify both the diagonal size (in inches) and the sensor model, and sometimes both parameters at once. Anyway, such data is provided only if the device is equipped with a high-class image sensor. With the model, everything is quite simple: knowing the name of the sensor, you can find detailed data on it.

The diagonal of the image sensor is traditionally indicated in fractions of an inch — accordingly, for example, a 1/2.3" sensor will be larger than 1/2.6". Larger sensors are considered more advanced, as they allow for better image quality at the same resolution. This is because due to the larger sensor area, each pixel is also larger and receives more light, which improves sensitivity and reduces noise. Of course, the actual image quality will also depend on several other parameters, but in general, a larger sensor size usually means a more advanced camera.

— Photo during video. The ability to take photos directly while recording a video — usually using a separate button. Thus, it is convenient to fix the most significant moments of what is happening. Such photos are much better in quality than "freeze frames" from the captured video.

— Serial photo shoot. This feature allows you to take several pictures at once in a short period (usually it is a fraction of a second). A series of shots increases the chance of capturing a good moment, which can be very important given the specifics of using action cameras.

— One click recording. The ability to quickly turn on the camera for recording — literally at the touch of a button, by the name. Moreover, such a button works even if the device is turned off. However, the recording inevitably starts with some delay; but often this delay is a fraction of a second.

— Online streaming. Ability to stream video to popular services like YouTube and social networks (Facebook, Instagram, TikTok, etc.). Usually, the online streaming function is implemented when the action camera is connected to the Internet via a Wi-Fi network, less often via a wired connection. Communication with the World Wide Web can be held directly or through a smartphone or computer. It will require the use of appropriate software.

— Time lapse. A special mode of operation of the action camera, in which video recording is carried out at a slower frequency is mainly used for filming slow processes. Thus, for example, a long journey or a long sunset can fit into a 3-minute video.

— Auto-rotate. The function of automatic rotation of the captured photos and videos to the position corresponding to the position of the camera. Without this feature, all footage during playback would be displayed strictly in landscape orientation, and footage shot with the camera upside down or upside down would have to be rotated in a photo or video editor. Usually, at the beginning of video recording, auto-rotation is blocked — so that the position of the frame at any time corresponds to the rotation of the camera itself relative to its original position.

— Photo panoramas shooting. The ability to use the camera to take panoramic photos. In traditional action cameras (see "Product type"), such shooting is carried out as follows: the camera takes several separate photos, which are then glued into one image. Regarding panoramic and 360-degree models (see ibid.), it is worth noting that not all such models support shooting in panoramic format, so it is advisable to check the availability of this function separately.

— Key points labels. The ability to add special marks to the footage that indicate key moments. While viewing such videos, you can go directly to the labels — this is easier than manually searching for the right moment. This feature is especially useful when shooting long videos, as well as when numerous individual files. The label, usually, is placed right during the shooting by pressing a special button or by voice command.

— Night shooting. Special mode for recording in low light conditions. The specific implementation of this function may be different: in some models, the sensitivity of the sensor is increased, in others, shooting in the IR range is used. Accordingly, specific features may vary: not every camera with this function can shoot in complete darkness, and these nuances should be clarified separately.

— Diagonal. The larger the screen, the more convenient it is to watch (and also to control if the display is touch-sensitive). On the other hand, the diagonal of the built-in display directly affects the size of the case, and action cameras should be quite compact. Thus, there are practically no screens larger than 2.5" in modern action cameras.

— Resolution. Theoretically, the higher the resolution, the clearer and better image the screen produces. On the other hand, displays in action cameras are designed mainly for menu operation and footage preview — and for these purposes, especially high resolutions are not needed. For models with two screens, the rear display is considered the main display.

— Touch screen. Display equipped with a sensor and responsive to touch like in smartphones/tablets. Control through such a display is simpler and more intuitive than using buttons, rotary knobs, etc. On the other hand, for more or less convenient control, the touch screen must be quite large, which affects the dimensions of the entire camera.

— Front screen. The presence in the camera of a screen mounted on the front panel, next to the lens. Other displays may not be present at all; in such cases, the diagonal, resolution and other parameters are given for the front screen.

It is worth noting that most often the simplest black-and-whit...e displays are installed on the front panel, suitable only for text and basic graphic information. However, even on such a screen, you can display a wide variety of service data: the current mode of operation (photo, video, standby), the resolution used, the shooting time, the amount of free space on the drive, etc. But more advanced displays are not used as front displays: a full-colour screen is needed only for taking a selfie, and for this you can use a remote display with a remote control(see "Control") or a smartphone connected to the camera.

— Protective case. A special container that provides additional protection against dust, moisture, shock, extreme temperatures and other similar “troubles”. The specific degree of protection in each case must be specified separately. In order not to interfere with the shooting, the box is made of transparent materials. In addition, we note that some cameras can only be mounted on mounts in a protective case (or in a mounting frame — see below), since the camera body may not have mounts for this.

— Curved mount(helmet). A mount designed to mount the camera on a helmet or other curved surface. The design of such a mount is based on a curved platform with an adhesive layer or hook-and-loop, the shape of which approximately corresponds to the shape of the surface of the helmet. Such a fixture can provide a more secure hold than the classic flat platform (see below).

— Flat mount. One of the basic and simplest mounts used to fix an action camera on almost any uniform surface: snowboard, skateboard, car hood, etc. It is a small flat platform, on one side of which the camera is attached, while the other is fixed on the desired surface (using hook-and-loop, special glue, etc.). Note that flat mounts are often used for mounting on a helmet. However, there is a separate type of mount for this, with a curved platform (see above).

— 3-axis mount. It differs from other types of mounting in the presence of three movable nodes that allow you to rotate the camera at an angle of up to 90 degrees in three axes. This allows you to choose the most interesting or successful shooting angle — on the side of the helmet, for example. Such options are usually compatible with many other mounts, so they can be used in conjunction with a handlebar, curved mount, etc.

— Bicycle/moto handlebar. Mount for installing the camera on a small pipe, such as the handlebars of a bicycle or motorcycle. Usually, it looks like a clamp, and the size of the fastening can be adjusted within a fairly wide range, adjusting it to pipes of different diameters.

— Suction cup(on glass). Camera mount, fixed in the right place with a suction cup. Allows you to install the device on flat and slightly curved surfaces. At the same time, note that such fasteners are not held as securely as flat or curved ones (see the relevant paragraphs). On the other hand, the suction cup is easy to attach and remove and leaves no marks. Therefore, mounts of this type are mainly used for installation on car glass when the camera works as a DVR.

— Clamp (clip). The clip-pin mount is quite versatile since it allows you to hang the camera on almost any suitable piece of equipment (backpack strap, unloading belt, belt, etc.). But at the same time, it is not very suitable for extreme shooting due to the relatively low reliability.

— Head mount. A device for fixing the camera on the head — usually on the forehead, like a headlamp. In addition to being hands-free, this placement has another advantage: the camera lens faces the same direction as the user. In this case, the mount itself is usually a system of elastic straps and is designed to be worn directly on the head, in contrast to the curved platform for the helmet. However, in some models, the possibility of putting on a helmet is also allowed.

— Chest mount. This mount is a system of elastic straps that allows you to fix the camera on the user's chest, shooting a little lower than the "eyeball". Like the head mount (see above), it easily adapts to the desired size.

— Mounting frame. A device designed to mount the camera on various mounts — helmet-mounted, on the handlebar, etc. The camera body itself often does not have mounts for such fixing, which is why you have to use additional equipment. Note that a similar function is often performed by a protective case(see above); the mounting frame, in contrast, provides almost no protection. However, in the frame, the camera body remains as open as possible. This provides additional features — in particular, it allows you to connect various cables and effectively use the built-in microphone, which is not possible with many protective cases.

— Monopod(selfie stick). It is a rod, usually folding, and sometimes adjustable in length; on one end of the rod is a mount for the camera and on the other — a handle for holding in your hand. By the name, such a monopod is intended mainly for filming itself — thanks to the length of the rod, the camera can be held at a convenient distance for this. However, other applications are also possible: for example, with the help of a monopod, you can “look” quite far over the edge of a cliff or around a corner. The main disadvantage of such a device is that one hand is constantly busy.

In addition to those mentioned above, other types of mounts may be included in the delivery package — for example, for musical instruments (for a guitar neck, a drum kit bar, etc.), for a surfboard, etc.
