How to buy wholesale MP4 players?

If you frequently buy wholesale MP4 players, do you pay attention to some of the details? As the popular digital products, there is the similar situation in the current wholesale MP4 player market which had ever happened in the MP3 market - the level of the products is different and mingled. In order to avoid the losses for the MP4 player wholesalers in the purchase of the products, we will give you some suggestions for reference.

The first: The wholesale MP4 players can directly play VCD, DVD and AVI video files on the network.

As the picture quality of VCD and DVD is good and relatively easy to obtain, at the same time clear pictures are not easy to cause eyestrain and can protect your eyes when you watch it. This feature reflects that the wholesale MP4 player is compatible with the video format. The video formats have the following types: MPEG-1 (VCD), MPEG-2 (DVD), MPEG-4 (AVI) and so on. The copy-play wholesale MP4 player which is able to support MPEG-1 (VCD), MPEG-2 (DVD) and MPEG-4 (AVI) format is a genuine MP4. Pseudo-wholesale MP4 players or video MP3 generally require conversion software to convert into their proprietary formats to identify. Only supporting the following types of files are usually video MP3, such as MTV, DMV, MPV, ASF, and AMV.

The second: The wholesale MP4 players have the color performance which is above 16 million colors (24-bit true color).

16 million colors screen can reflect the contents of the screen more realistically, all levels of color can be very fully performed, and it will not have any color differences. Bad wholesale MP4 player screen will appear uneven color first, stiff color transition, or even appear the situation of dark red instead of pink. The color number is an important indicator to measure the display effect of the wholesale MP4 players, which is the most total color, can be shown on the screen. In theory, the higher the numerical value is, the brighter the colors are, the better to restore. At the same time, the high chromatic number can be effective in preventing the emergence of color lump and show more realistic visual effects. At present, there are several criteria for the mainstream of the wholesale MP4 players on the market: 65,000-color, 260,000 color and 16 million colors. Of course, 16 million colors is the most outstanding one of the three. For 65,000 and 260,000 color screens, in the abundant color transition areas, you can see a lot of color lumps, but the color transition is very natural on the screen of the wholesale MP4 players with 16 million colors.

The third: The wholesale MP4 players support 720× 480 resolution or above.

The wholesale MP4 players with high resolution can display the subtle details very clearly. The high definition picture quality of MP4 with display resolution of 720× 480 can achieve the effect of DVD. There are a lot of wholesale MP4 players who flaunt themselves as high-definition screens on the market, as a matter of fact, only a few can achieve a resolution of 720×480. Display resolution is the pixel number of video image display, display resolution of 720×480 means that the level pixels of the video images are 720 and the vertical pixels are 480. The higher the display resolution is, the bigger the number of the pixels is, and the more sophisticated the images are. With the same size screen, the higher the resolution is, the more sophisticated and delicate the display effect is. The mainstream display resolution of the MP4 is QVGA (320×240), VGA (640×480), and D1 (720×480). For the wholesale MP4 players, the high display resolution is of great significance to the quality of video output.

The fourth: The wholesale MP4 player video files can be played for 30 frames/per second.

Generally, most films are 24 fps (frames per second), and 24 fps is the bottom line for the human eye to identify whether the frame is smooth. Less than 24 fps, the frame is not smooth; more than 24 fps, the bigger the frame rate is, the smoother the frame is. Video is to take pictures of the moving images at a speed of 24 frames per second at least, and then play the pictures consecutively and rapidly at a speed of 24 frames per second, as a result of residual visual phenomenon of the human eye, people can not see they are the 24 pictures, what they see is a continuous action, that is video, and this is the principle of making movies, each picture is a frame. When you buy the wholesale MP4 players, you'd better try to avoid using the animations as test films, and play the ordinary movies, especially some fast flow screen and big action movies. According to the rich color of the film and the movement, you can see whether the image is smooth and there is a sense of standstill.

The fifth: The wholesale MP4 Player lithium battery can actually work for more than four hours.

The video display of the wholesale MP4 Player is a core function, the built-in high-energy lithium battery is required to ensure the sufficient display time. A lot of products in the market are strongly publicized for the high capacity of the wholesale MP4 players in order to make people ignore the factor of the battery. If the playing time is only two hours, how can the wholesale MP4 player display its content completely?

The sixth: The wholesale MP4 Players adopt high speed USB2.0 interface.

This is surely a problem that can not be ignored, a lot of people are attracted by the appearance when they buy the wholesale MP4 players, and they are so pleased that they forget the other things they must concern for. However, if there is no high-speed transmission for the movie with more than one GB capacity, it would be very depressing. At present, the USB interface can be divided into USB2.0 FULL SPEED and USB2.0 HIGH SPEED. The former is the old USB1.1 standard in the past, in fact, many products' description are very vague, which is suspected of misleading the consumers. We have to understand what we need, and if you ask them, I believe that no one dares to take USB1.1 as USB2.0 to deceive you.

The seventh: The wholesale MP4 players adopt at least 2-inch LCD screens.

The size of the common wholesale MP4 player is the diagonal size. If the MP4 tagging is a 2-inch screen, it refers that the diagonal length is 2.0 inches. On the current market there are some digital products which seem to have a large screen (as opposed to the general mp3) and can simply play videos, they claim to be the wholesale MP4 players, this gives us a deep understanding that the screen is the most confusing thing for the consumers. It can be said that the size of the LCD screen of the wholesale MP4 player is a part of the wholesale MP4 player indicator, as a true wholesale MP4 player, the screen can not be less than 2 inches.
