1. In the Apple 5s we clicked on the camera image and went to the "camera mode" of the cell phone.
2. As shown in the following illustration, we slide the slow action bar on the screen of the photo interface and click on the "recording" details as shown in the picture.
3. Now we can click on the White button to take a picture while filming. If not, click the red button directly, as shown in the following figure.
4. After the shoot, we can preview in the phone to see the slow

D: distance between two circles. A: R1-> O1-> O2
Cos A = (R1-R2)/X if O1 is (0, 0) and O2 is (x, 0), the above two cut points are (R1 * cosa, R1 * Sina ), (x + R2 * cosa, R2 * Sina) the general position is translated and rotated based on the result.
Known circle O1, O2, coordinate (x1, Y1), (X2, Y2), radius is R1, R2

Chain movement, as the name implies, tied up, that is, after the execution of an event, then proceed to the next event, the argument above the foot, the next function to execute the name as a parameter, that is, the use of the return function, the following code appears in the FN, that is, the return function,1 functionMove (OBJ,ATTR,TARGET,FN) {2 clearinterval (obj.timer);3Obj.timer = SetInterval (function(){4 varIcur=0;5 if(attr = = ' opacity ') {6Icur=parseint (parsefloat (GetStyle (o
Why is the speed of 24 frames per second sufficient for a movie to achieve a smooth visual effect, but it seems bumpy for computer games? The reason is very simple. when the camera is working, it does not take a frame at rest. Each frame it takes already contains all the visual information within 1/24 seconds, including the object displacement. If you press the seek key when watching the video, what we get is not a clear static image, but a blurred image, because of this. The computer cannot do
Offset bug in Javascript motion-line-by-line code analysis allows you to easily understand the principle of motionLet's take a look at how this bug was generated.
1 First use the Apple phone to open the camera to choose "Slow motion" shooting video, after the completion of the video shot click on the top right corner of the "camera." (pictured below)
2 then select the video just shot click "√", after the completion of the crop click on the upper right corner of the "√". (pictured below)
3 finally enter the content you want to say and click "√" to complete the production. (pictured below)
Career development, code 100 days--2018-04-23I. BASIC framework of movementThe motion of JavaScript can be broadly understood as the gradient effect, the direct movement effect, etc., the common "share to", the banner, the transparency change and so on on the graph webpage. The basic way to achieve this is to use the timer that you learned earlier.Through the study, summarizes the basic movement realization--the m
It is estimated that motion blur is performed using the speed of movement, but often the motion blur is linearly variable, although at first glance there is no problem, but if you want the fuzzy trajectory of each frame to be curved rather than stiff, A motion blur that uses trail to calculate speed is never going to do that.Here I want to talk about some of the
Javascript perfect motion framework-line-by-line code analysis allows you to easily understand the principle of motion, javascript line-by-line
Once you hear this name, you will know that the online effects of this framework can basically be achieved. In fact, the previous motion frame still has limitations, that is, it cannot let several values move one piece.
JS perfect motion framework and JS perfect motion framework
Function getStyle (obj, name) {if (obj. currentStyle) {return obj. currentStyle [name];} else {return getComputedStyle (obj, false) [name] ;}// note: In a multi-object motion frame, nothing can be shared! Otherwise, a problem occurs. add necessary variables to the attributes of an object. That is, the p
A swinging motion means that an object is reciprocating around a certain axis within a certain angle. Now we use js to simulate it. The implementation principle is to use setInterval or setTimeout to dynamically change the distance between an element and an axis. First, the element is located near the axis at a certain position (with a speed of 0 ).
A swinging motion means that an object is reciprocating
Then the last article "JS Sports-chain movement" continue to tossOur motion framework in the previous article can be perfectly implemented so that an object becomes wider, higher, and more transparent ... it looks perfect!Looks like can drink tea to see the beautiful woman. But the boss suddenly said, let you change the width and transparency of an object at the same time, heart-broken a ground!!!Take the previous
There are many JavaScript effects on the Internet. The biggest feature of these effects is "motion", that is, animation effects. In fact, the use of Javascript in Web pages has become a trend in recent years, and Flash, which has been quite cool in the web page animation field in the past few years, is also a little low-key this year. After all, as a rich clientProgramFlash is a little bulky for the tangled bandwidth, and Flash must have plug-in suppo
Javascript chained motion framework-line-by-line code analysis allows you to easily understand the principle of motionThe so-called chain movement is a link. In fact, many of our sports refer to stages. The first stage is complete and the next stage starts to change. This chained motion frame is used to solve these problems. Let's take a look at the previous motion
In web chat, using GIF motion diagram has become the norm. Many people are accustomed to use GIF animation to express their feelings, then you have to think about your hands of the GIF animation is how to make it? I think I must have thought about it. In fact, it is not difficult to make GIF, there is moneyQuick GIF Authoring toolAdd a link description and you'll be able to navigate it easily. The following small series to share under the production o
Analysis of adding motion methods to any value of JS motion effects, js Effects
This article describes how to add motion to any value of JS motion effects. We will share this with you for your reference. The details are as follows:
Let's take a look at the previous example of JS's method for implementing multi-object
Everybody listens to this name to know, has this set of frames the net effect basically can realize. In fact, the previous frame of motion is still limited, that is, can not let several values a piece of motion.
So how do you solve this problem? Let's take a look at the previous motion frame.
function GetStyle (obj, name) {
if (obj.currentstyle) {retur
