In this part of the article we will talk about what characteristics of modern video cameras should be taken into account when choosing, as well as try to answer the most frequently asked questions.
First, we need to answer the question: “Do I need a high-resolution video camera or will a standard-resolution video camera be enough?” The answer to this question depends on your viewing equipment (or planned to be purchased).
After all, if you want to watch your video on a regular TV with a diagonal of 21 ”, then we can confidently say that an HD video camera will be a useless purchase for you, all the charms of high-definition video will be“ killed ”by an inappropriate viewing device. Moreover, it makes little sense to watch HD-video on conventional TVs with diagonals up to 29 ”inclusive – you will not see much difference compared to standard-resolution video. Another thing is if you have an LCD or plasma TV with a relatively large diagonal – here high-definition video reveals its advantages. Continue reading
First of all, it should be noted that, without exception, all modern digital video cameras use certain compression algorithms and compression of the original video, and the “recording format” just characterizes the compression algorithms used. Let’s see what recording formats are found today in standard-resolution digital video cameras; we will talk about high-resolution video cameras separately, a little later.
DV is a video format with frame-by-frame compression (compression), that is, each frame of the video is compressed individually. At the same time, the compression ratio can be variable within the same frame — areas of the image that are difficult to compress are compressed with a lower compression ratio, and simple ones with a larger one. In this case, the total compression ratio for the entire frame remains constant (5: 1). The resulting stream for video is approximately 25 Mbps. The DV frame size is fixed and is (for the PAL standard) 720×576 pixels. This format is used in miniDV camcorders, and video recording, respectively, is performed on miniDV cassettes.

It is no exaggeration to say that with the phrase “action camera” most people associate a very specific device. “Camcorder for extreme sports? Is it like Gou Pro, or what? ”, They usually respond like that if you are talking about some analogue. That is why not only windsurfers, ruffers and freestylers of all stripes were waiting for Go Pro 4, but in general all those who are at least a little interested in video filming.
According to the old tradition, GoPro 4 was presented immediately in three versions: Black, Silver and just Hero. Typically, all these cameras are the same color, the difference only applies to their characteristics. Continue reading
