Compare and share: Canon IXUS140 has 8 times times optical zoom lens, focal length is equivalent to 35mm 28-224mm, set up intelligent automatic shooting mode, can at any time for the image to be photographed intelligent judgment and analysis, and choose a relatively suitable way to shoot, can automatically identify 32 kinds of scenes. While Canon

. Canon 5D Mark II has the ability to take full HD short films, which can be filmed in both the Full HD and SD formats, in the form of MOV, the resolution in full HD format is 1920x1080 pixels (16:9), and the resolution in SD format is 640x 1920x1080 480 pixels (Vga,4:3), the frame frequency of both formats is 30fps. Through the HDMI interface on the machine to connect High-definition TV, or through the video output terminals connected to the genera

This tutorial introduces the use of Flash CS5 to make mouse-triggered fireworks falling interactive effects, mainly with the calculation of mouse following objects to produce a certain pattern of spark effects. 　　idea: Import the background material, and then make the fireworks falling effect. Create a document class that produces a multiple-angle star effect that follows the mouse, creates an extension class of the component class, and produces a random size spark. With the mouse on the scree

Dynamic | tutorials In some of the titles or MV animation we often see a very bright blur effect, very visual impact. Most of the high quality of fuzzy effects are used in bitmaps and other software (such as: Photoshop) processed before importing into flash for production. In fact, in Flash can also use its powerful scripting features to achieve dynamic blur effect (although the effect is almost: P). Watch this example effect: Production ideas: Use the loop and Attachmovie methods to attach mov

After the tutorial, in this article will introduce to you: ruler, grid, to create a better circular picture special effects, and to introduce the content of action, I hope you like! Start learning below: First, let's take a look at the initial effect: Please click here to view the previous 1-19 steps, the specific production effect. 　　Download the animation material of this website 1. First create a new Flash file, save as "Planet_start.fla" 2. Press Ctrl+r first to import a background picture

Programming Ideas: 　　First draw a drop from the drop to the scattered raindrops, and then continue to copy the raindrops to the screen, resulting in the effect of rain.Steps: 1. Open Flash MX 2004, new document, set document size 550*400 pixel, frame frequency set to 30FPS, background set to black. 2. Press Ctrl+f8 to create a new movie clip symbol in which to draw a drop from the drop to the scattered raindrops (shape gradients and action gradients a

%. Canon D30 is equipped with a 28mm wide-angle lens and has 5 times optical zoom, which makes it possible to shoot high quality clips from a full HD video. Canon D30 supports the highest 1920x1080/30p format video, and also supports 120fps, 240fps slow motion video shooting, and short film summary functions. While Canon 7D supports 1920x1080 pixel shooting, it also offers 1280x720 pixel and 640x480 pixel video shots, and can record up to 25fps Full HD video and 50fps of non-full HD

mainly reflected in the unit. You should take a look, the average manufacturer provides the unit is CIF. CIF can be seen as a fixed-resolution nickname, CIF is the 352*288 resolution. The camera at this resolution is ideal for up to 30 frames per second, similar to the nickname: qsif:160x120; qcif:176x144; sif:320x240; vga:640x480. From the actual speed, the computer camera in the Qsif, Qcif state to reach 30fps, in the SIF, CIF state of 20~26fps; in

following is a camera shot down the iphone SMS program screen switching animation, will be animated single frame playback, you can get the following series of screenshots. Because each single frame screen has the same time interval. We put the results of each frame change on the axis and try to quantify the elegance. D represents the distance, the total size is the width of the screen. F is the number of frames, press 30fps for approximately 0.4 s

Control Today to tell you about the use of the keyboard in Flash to control the movement of objects in two ways, is the use of Flash ActionScript updateafterevent and onenterframe to achieve. When viewing the effect, click the Flash movie with your mouse to see the effect with the keyboard key. First look at the effect 1: Look again effect 2: Click here to download the source file Effect 1 I am using onenterframe to achieve, the effect of 2 I am using updateafterevent to achieve. first, declar

I can't wait for control, right? Come on, let's join the game's lead plane. You can position this game in action games, an action game requires constant input from the client, basically uninterrupted, so plane need to constantly change the position. So how many frames should this frame-based game be set to fit? This need to test in the mobile phone, in the simulator, if set in 15-18 frame around, is more appropriate. Listen to CSDN several XD said some games are only set in 12 frames, so differe

unit that is replaced by the sampling frequency, so that the purpose is to be more precise in the timestamp unit. For example, if an audio sample frequency is 8000HZ, we can set the timestamp unit to 1/8000.Timestamp increment: The time difference (in timestamp units) between adjacent two RTP packets.How to set the increment between timestamps.According to the time stamp unit, 1 seconds according to the timestamp unit is 8000, then a second if you can play 20 frames, that is, send 30 frames (fr

the current video frame rate is 25fps, then the timestamp interval or increment should be 3600, if the frame rate is 30fps, then the increment is 3000, and so on.About H264 unpacking, according to the Fu-a Way description:1. The first fu-a package of Fu Indicator:f should be the current Nalu head of F, and NRI should be the current Nalu header nri,type is equal to 28, indicating that it is fu-a package. The FU header generation method: S = 1,e = 0,r

Camera2Camera2 is one of the new features in Android5.0, the new API. Compared to the original camera API, the difference is: Native support Raw photo output Burst shooting mode It is no longer software but hardware that restricts the speed of photography. With Nexus 5 as an example, the continuous shooting speed of Andorid L can reach 30fps at full resolution. Full Manual control Various parameters such as shutter, spe

two full screen images? How much FPS is saved? This method is called the reverse painter algorithm. However, the reverse painter algorithm is not used casually and must support Z-buffer. And, most importantly, the Z-buffer sequence should be set correctly. For example, if a overwrites B, the Z value of A is smaller than B, that is, a is more advanced, and then the normal draw order is reversed, we achieved our goal of optimization. At this point, some people have asked, to what extent can we op

filter for the texture. This filter can be set to the clamp mode. The second problem to be addressed is that the texture sampling coordinate in pixelshader is 0-1.0. If you want to get the size of the texture image on the top left, in this way, the offset of a pixel can be converted to a value ranging from 0. Assume that the texture size is [W, H] and the current texture coordinate is [U, V]. Then, the texture coordinate of the pixel in the upper left corner of the image is [U-1.0/W, v-1.0/h]

graphic processor can update each second when processing the field. A higher frame rate allows you to get smoother and more realistic animations. In general, 30fps is acceptable, but improving the performance to 60fps can significantly improve the interaction and authenticity, but generally it is not easy to notice that there is a significant increase in smoothness when it exceeds 75fps. If the frame rate exceeds the screen refresh rate, only the gra
