Lei feng’s network by: this article is reprinted from micro-official information release platform “app”. Original title: the micro or small video of those little secrets. Why micro-video maximum time is 6 seconds? Small video consumes how much traffic? Small video is so small, can you clear?
“Black is not black, what do you say white is white. ”
You must have experienced and saw a beautiful or interesting scenes and wanted to record and share, but found nothing. Even if it is to have dinner with friends, often have such a dialogue:
You in there? What did you see? To give an accurate description of a thing is not an easy thing.
Words video, in order to solve the problem of sharing in real time, the app version 6.0 was launched in “little video” features: users can directly from within the app to enable camera, shooting up to 6 seconds of video dialog box to send video to friends, or post in my circle of friends.
App version 6.0 will be small as core video highlights one of the proclaimed coming of the video age. Until now, a lot of users have become accustomed to with a small video sharing life’s fresh and moving. No more silly typing, no longer considered expression, short videos to help you achieve “what you see is what you get”.
But, you know, Juicy Couture iPhone case
| Why is the longest video only 6 seconds?
In many cases, users often in outdoor use app, unstable network, traffic was restricted, not very suitable for users to post or view a larger volume of video files. Video length limits (no more than 6 seconds), and optimization, which became smaller in size, only better in mobile publishing and viewing.
Small video processing for 6 seconds, mainly in order to reduce receiver volume pressure and psychological pressure during playback. In fact, before the official release in small video, micro-letter “attacking lion” for as long as six months of testing, 6 seconds is the most appropriate length.
To do the test, the developer also wrote the “kitchen” debugging tool, as a global variable configuration of the switch module instead of a numerical, configuration take effect immediately to facilitate debugging. It is like a PS tools help developers find the optimal path. Length 6 seconds it is in the support of finding the most suitable length. Juicy iPhone 6 case
| Are small video, then how small the small video of traffic consumption?
There is a very simple conversion: small video chat, the size of each video is approximately equal to 2 friends picture size, each circle of friends small video is approximately equal to 3 friends the picture size.
And longer videos than 6 seconds the small amount of video data in the iOS system for 400KB, the Android system is 200-300KB, which means, three small video traffic is about 1MB.
Furthermore, small video loading logic is seen no longer loads, didn’t read the do not load, is loaded, take the initiative to help the user save traffic.
Text is too stuffy, picture is too quiet, small video just fine.
So, whether it is a small video or watch short videos do not have pressure. By today’s standard for traffic costs, such as China Mobile’s 500MB plan 30, only three small video 1MB, or about 0.06 Yuan.
Not sure, just shoot a little video. If a small video that is not clear, it would take two. If the two small videos also don’t know, those three small video can.
| Problems coming, small video so small, can still see it?
This is speaking of bit rate and resolution of these two Visual “clarity” is closely related to the parameters.
Rate determines the quality of the video, the original higher bit-rate video more clear, and the resolution determine the video image magnification. Bit rate to the following principles:
Is proportional to a, bit rate and video quality, but the file is proportional to the volume and rate.
B, the rate exceeds a certain value, without much impact on image quality.
Compare with long videos, video coding algorithm for video there is no major difference. But because in less than 6 seconds, the volume is greatly reduced, and mainly play on the mobile side, micro video finds a balance between quality and size, allowing users to use without any pressure.
In fact, small easy to use video, interactive experience, not just traffic consumes small, open without pressure. In order to receive better interactive experience, during the filming of recording and playback, the “video” there are lots of little secrets you don’t know, such as:
Preboot-the press on the record. Small video press the start recording, do not wait for the audio device and document preparation. So that you can guarantee in the transient moment to capture the content you want to capture. Imagine the clock for each photo, you know how important this small feature.
Shake monitor–you shake the reminders. In order to ensure the effects of shooting, according to the change of acceleration gyroscope, the system will automatically detect the phone shaking and remind.
Environmental monitoring-dark-too dark to choose brighter: too dark when shooting environment, small video prompts you can use “light mode” to optimize the shooting environment. So intelligence is how to achieve this? In fact, the RGB color value of each pixel in the video are not the same, for fast processing and response by scaling it, getting an average, when the RGB average value below a certain value, such as less than 17 o’clock, pop-up prompts to quickly distinguish between light from the environment.
Mute–click to enlarge sound plays. Only click to enlarge small video with sound when playing and looping effects close to GIF. When and when not full screen, record a small video to keep quiet playing.
In iOS release optimization process, more technologies team to design micro-programmes, chose to bypass the iOS system players at the same time there is a maximum of 16 limited homegrown video player, to meet the needs can play multiple videos simultaneously. And in order to prevent playback interface stuck when shooting situations, join the Cache layer in the video recording, cached video frames, follow-up to waken the CPU is idle thread writes in the background video.
These painstakingly “action” without attention and let you know what focus, zoom, exposure compensation, white balance … … Wait, you just need to pick up the phone.
In the “video” before the app that you can send videos, short video or some other platform. However, you need to temporarily stop something else, according to the recording, press stop, then confirm sending. Complicated steps, video is also great. People who receive video, viewed only as Wi-Fi.
Micro letter 6.0 brought in Harry Potter “newspaper magic” video, both programmes are, or in the food, or many other emotional moment in your life, you can use a small video, share it vividly.
It embedded directly into the chat scenes, pass without making up, landscaping, bad information, “press and hold” the minimalist way to get you involved, to better facilitate interaction. It’s like eyes, bring you a taste of the changing of the seasons.
Hey, a familiar feeling.
