In this lecture interview, we invited the lecturer of this LiveVideoStackCon 2020 Beijing station and the technical director of Moxiang Technology Liu Zhimei to do the interview. As an Internet practitioner, especially an expert in the field of service content production, I think this interview Derived from an event that everyone is paying more attention to recently.
9月29日消息，昨日晚间23 时 59 分，
腾讯微博正式停止运营。
目前用户已无法登录腾讯微博，但仍可备份数据。
LiveVideoStack: Some time ago, the Tencent Weibo team announced that Tencent Weibo will cease operations. Once upon a time, the most popular products in the Internet field were mainly blogs. Because the settings were too free, they were replaced by simple and brainless Weibo and social networks. . Have you ever used a blog to record your life before? Weibo can replace the sudden emergence of blogs and short videos have been favored by more and more users in the past two years. Do you think there are similarities between the two?
Liu Zhimei: I seldom use Weibo. I write some blogs, but I mainly focus on explaining technology. Weibo and blog, just like poetry and prose, are just two different forms of content carrier, there should be no replacement, but in terms of popularity, Weibo does win out:)
The reason why Weibo has become popular is the serious fragmentation of time; creators do not have a continuous period of time to do in-depth creation, and must use the least words and pictures to convey their mood, opinions, or other things; similarly, consumers are not continuous A lot of time for deep reading (of course, many people do not have the need for deep reading).
The popularity of short videos is based on the same logic.
LiveVideoStack: Short videos are in line with the current fragmented content consumption habits. If you only take more than ten seconds of content, you can even use a mobile phone. However, if you edit and splice on the basis of multiple video materials, the production threshold is not high. , But it is enough to reject many users with creative enthusiasm. From the perspective of smart hardware manufacturers, what are the characteristics of smart hardware that can free up creators' production costs to the maximum?
Liu Zhimei: Video creation faces two major difficulties: material and editing .
As a 2C smart hardware manufacturer, the most direct approach is to start with the material and make professional-grade photography equipment into consumer-grade, so that ordinary users can shoot professional material quality.
The hard core should be hard enough: imaging speed, color, resolution, etc. should be professional-grade, natural anti-shake, built-in wide-angle, etc., and professional-grade.
However, the appearance should be portable, compact and stylish, and simple and easy to operate. Don't make users worry about it .

LiveVideoStack: There are actually many smart hardware devices on the market for shooting short videos, and even some camera manufacturers have successively introduced models that are convenient for Vlog shooting, but for different usage scenarios, especially high-speed sports scenes such as skiing, cycling, and downhill. , Image stabilization and fixed focus have a great impact on the quality of the final film. Which technologies are integrated to achieve this?
Liu Zhimei: The anti-shake of many sports cameras on the market mainly adopts optical or electronic anti-shake, the purpose is to avoid image blur, but the picture will still shake if it shakes :)
Regardless of optical image stabilization or electronic image stabilization, the basic requirement is fast imaging , including the processing speed of the lens group, sensor, and MCU.
Anti-shake is essentially at the expense of imaging speed to meet imaging quality, but if your imaging speed benchmark is high enough, users will actually be insensitive.

LiveVideoStack: Every technological innovation in the Internet industry is to make richer data and content more accessible to people on the Internet. The reason why most people choose to shoot short videos directly with their mobile phones is largely because the mobile terminal has a wealth of video editing software to choose from, shooting, editing, and uploading in one step. If the creators are to be liberated to the greatest extent, what user needs need to be taken care of in software services?
Liu Zhimei: I mentioned two major difficulties. Editing is hard work. The first thing to do is to choose the film. Selecting the clips that meet the requirements from the mass of materials is a boundless sea of hardship for ordinary users to create video.
Followed by sequence arrangement, special effects, transitions, BGM, and subtitles, etc., are also piled up with dark circles and hairline.
Nowadays, the common practice is for professional users to make templates, and ordinary users to make follow-up shots. This does reduce the cost of creation, but it also brings other problems.
LiveVideoStack: Returning to the question that led to this interview at the beginning, Weibo replaced blogs in the form of updates. Short videos are nowhere near the limelight in the current Internet world. There may be updated interactions in two years or even less. The recent enthusiasm for short video delivery also proves from the side the change in tuyere. What are your unique insights on the "form of expression" of future content? From the hardware point of view, whether sports cameras and handheld gimbals can meet the future User needs for a long time, from the software perspective, what technologies still have room for improvement?
Liu Zhimei: Whether Weibo, blog, live broadcast or short video, the essence is content creation, and the core is still on the content itself, so that good content will have an audience .
From the perspective of product form and usage scenarios, neither sports cameras nor handheld gimbals can fully meet user needs, and there is still a lot of room for improvement; for example: miniaturization, battery life, high-speed imaging, etc.
This is especially true at the software level. Film selection, editing techniques, and even creativity all require updated technical support; for example: video retrieval, semantic generation, etc.

On the eve of the LiveVideoStackCon2020 Beijing Audio and Video Technology Conference, we invited Liu Zhimei, the technical director of Moxiang Technology, to be interviewed, discussing from the popularity of Weibo and short videos to the severe fragmentation of user time, and how to better serve in the era of fragmentation Users, of course, this is a headache for every smart hardware manufacturer. On October 31st, Teacher Liu Zhimei will also share how to help users create high-quality video content from the software and hardware level.
