Create Reflected Perspective View Image in PP 2007

You may see some cool reflected perspective view images in many web sites or presentations. Fancy to create your own ones but don't know how to use Photoshop? If you have PowerPoint 2007, you can do it with just few clicks, it's much easier than you think. Follow me.

Below, the left is the original image, the right is the final image,










Insert an image to your PowerPoint 2007. Adjust it to a proper size (leave enough margin for reflection and shadow). double click on the picture, then the Format ribbon appears. Choose the preset style 'reflected perspective right' from the style gallery. Now you have your image in perspective view and a reflection. right click on the picture, choose Format Picture, 3D Rotation, Perspective, change the value until you satisfy the perspective level. Then, click Shadow, choose Perspective Diagonal Upper Left from the Presets gallery. Close the dialog, Ok you have it.

Choose The Right Tool to Record Screen

Good question. I have seen it on many ask & answer sites. This is would be a problem for many beginners. Also, even some computer geeks would have demand to create software demonstrations to assist depicting their operations, but have no idea which software out there meets their needs. In this article you can get a proper solution for most condition.

Why record actions on screen?

Say you find some favorite videos and flash movies from web, or found a great software tricks and want to share with your friends, but don’t know how to represent your actions on their screen. You play a game or find game tricks/secrets and want to show your play on web. You're trying to describe a computer problem to a technical friend or instructing software skills and you're trying to describe what you see on the screen: the operation sequence, the dialogs, the messages, the buttons whatever. You're not sure of the terms to use and your friend is having a difficult time understanding your description of what you see.

You must be desperate to own a tool that can help you represent what you see on screen. Screen recording tools can help you realize it.

Choose a tool wisely

Record video
To record video on your computer you need video recorder. Though most screen recording tools claim that they can record videos, or turn screen record to videos, only software designed to record video can generate high quality videos (sometimes could be flash movies). Usually you get a really big output file (a 1 minute 640*480 resolution video clip is about 200MB). You need a video conversion tool to convert the AVI movie to a small one, for example MP4, WMV and so on. Some sophisticate screen recording tools can produce high quality and highly compressed videos (a 1 minute 692*368 video clip is about 10MB), for example, Applian Technologies Replay A/V and ZDsoft video recorder. I will write a review of video recording tools in later June.

Record actions on screen
This is different from recording video. You only record your actions on screen, such as mouse move and keystrokes. All most all screen recording tools can make this. There are two recording approaches used by capture tools, one is capture specified frames per second, the other is capture only when you take actions on screen. The first method usually produces larger file size than the later one, but may keep more details, e.g. instant change with mouse over. Most demo creation tools implement the second capture method, and some of them support both approaches. Many recording tools of this kind are called demo creation tool, they are designed to create software demonstrations, tutorials and simulations. The screenshots captured by those tools can be edited to create an instructional movie. You are allowed to add annotations and narrations to polish or enhance your demos. Some can even create scenario based simulations, such as Adobe Captivate, Tanida DemoBuilder and Wondershare DemoCreator. What I want to highlight here is DemoCreator. It is a freshman in this field, but performs no bad than a sophisticate tool. I’m impressed by its intuitive interface and capture quality. Other tools can cope with this: Flash Demo Builder, ViewletBuilder, TurboDemo, Instant Demo, Wink (it’s free), SWF Demo Maker.

Record game
Tools use the first capture method can do this, but because playing game requires so much system resources that may cause the captured video laggy if the capture tool consumes much system resource either. So, I suggest tools designed to recording games, for example fraps, ZDSoft Game Recorder. Fraps provides game recording samples on its site, http://www.fraps.com
You may download them and take a look. ZDSoft released comparison of ZD Soft Game Recorder, Fraps and Game Cam
http://www.zdsoft.com/game-recorder/comparison.html

Record PowerPoint presentation
General speaking, people using this kind of tools wants to convert PP presentation to flash movie for Web sharing or across OS playback. Though you may find PowerPoint to Flash tools on the Internet, they cannot convert all effects in the original presentation. If you record presentation while playing, you keep every subtlety in the converted flash movie. The only deficiency is that you lose the link in it. Software convert PP presentation to flash movie by recording, Camtasia, ViewletCam, DemoCharge, Captivate. PP to flash conversion tool, Articulate Presenter, Wondershare PPT2Flash, FlashSpring. Robin wrote an article named, The PPT2Flash Top 20. You may refer it for more details, http://www.masternewmedia.org/2004/04/14/powerpoint_to_flash_conversion_tools.htm

Tools I introduced in this article are free to try or just free, you can download them by searching their name on download.com

Impress Students with an Interactive Presentation

An amazing interactive presentation always helps teachers and tutors to enhance their instruction. No matter you are a teacher or trainer, if you want to please your students or trainees with intriguing presentations, this is the right article for you.

Many people may understand the value of a good presentation for knowledge delivery, but only few of them do know how to make such one. Usually, teachers or instructors use PowerPoint to create courseware. Without a doubt, this is an easy and efficient way to help clarifying and activating the learning content. But, a presentation only with words and pictures is not attractive enough to get focus. Fortunately, MS PowerPoint allows user to launch an external program, e.g. exe and flash, while playing slide show. These elements may possibly bring clarity and fun to classes or lectures, but the problem is how many non-computer-science teachers or professors know to build those elements to content their students or audience. For sure, there are few. Then, how to create those interactive elements becomes the main hurdle to author attractive learning content or presentation.

Consider .exe first. What do .exe programs help? Take physics class for example. Usually, a VB program is used to demonstrate some physical phenomenon, e.g. beats, interference, diffraction and so on. Remember, these demonstrations are not only show the phenomenon, but also demonstrate the laws, which is more important than the phenomenon itself. In other words, the related parameters should be allowed to change to meet specify needs, such as, wave length, frequency, initial phase, etc. If not, a video would be more helpful. Ok, now the sticking point is VB programming. Oh, god, what a jerk! Luckily, in most conditions, those programs are universal to familiar content, for instance, a program demonstrate the phenomenon beats. The basic parameters would be possibly changed are frequency, amplitude, and phase difference. A program satisfying this is suitable for any class about beats. And, this kind of demos are available on Internet by searching ‘** demonstration’. Since it’s easy to get one, why bother to make one.

Then, flash. Flash is capable to manage most functions .exe programs can. Besides, flash is easier to please audience by visual animation looking than the .exe programs, and it is more acceptable in programming skill. Thus, the flash demo is becoming more and more popular. Just like .exe programs, flash demos can be downloaded from the web, but only one element would never get an appropriate one from the Internet. That is quiz. This must be distinct from different individuals. Even in the same course, teachers would like to have their own quiz. Now the problem becomes simple, build a flash quiz to enhance the interaction of presentations.

Why quiz?

Quizzes can help reviewing knowledge, and solidifying the instruction। What’s more important is quiz is absolutely interactive. Furthermore, a good flash quiz will get students’ focus. Beyond all doubt, Macromedia Flash is the best choice to create the most impressive and exclusive quizzes, but if we take a compromise on appearance, we are possible to avoid programming. Articulate, Tanida, and Wondershare all provide powerful flash quiz tools.

Articulate QuizMaker (QM), the most powerful, also the highest price $399, quiz tool among the three। It is capable to build either online survey or graded quiz. Friendly interface, users could start to make quizzes without a guide. There are 21 question types to choose, 11 for graded quizzes, True/False, Multiple Choice, Multiple responses, Match (drag and drop), Sequence (drag and drop), Fill In The Blank, Click Map (hotspot), Word Bank, Match (drop down), Sequence (drop down), Numeric, 10 for surveys and polls (Consider survey is not necessary for a class presentation, I only list the graded question types).

Tanida QuizBuilder (QB), $199, and Wondershare QuizCreator (QC), $99.95, less comprehensive than QuizMaker, are only focusing on the graded quizzes. The interface of QB is very neat, while the QC’s is very cute and pretty. The later one is more intuitive than the first. It is especially worth noting that only QC gives a question outline in the left part of its interface, it helps much on clarifying the quiz structure. They both provide 8 question types to choose. QB has the first 8 types of QM; QC has the first 7 types of QM, plus Short Essay.

Besides, Articulate and Wondershare provide robust flash authoring tools (make flash from PowerPoint), and they both can incorporate with their own quiz tools seamlessly। Turn PPT presentations to flash ones could reduce size dramatically, and can be played in computers without office.

All of the three products are easy to use, require no programming skills. Comparatively, QM is more professional than other two, but the price is triple as the QC. QB is not bad; the only deficit is the company provides no cooperative products.

Now, download and try. Build your own intriguing presentations, then share them with your lovely students! If you have any ideas please feel free to share your experiences with me.

How to Play 4:3 PPT on 16:9 Screens without Distortion

As the 16:9 HDTVs and LCD monitors become more and more popular in our life, how to play the 4:3 PPT presentations in full screen mode on these new babies without distortion is a big problem to many people. It seems impossible to make it on the face, but how about if we try to add something to fill the blank part of the screen. Please follow me, I’ll show you step by step.

Assume we have a 16:9 wide screen, and try to imagine a rectangular of which the width is 16 inches and the height is 9 inches. The rectangular comprises two rectangle regions, one is the gray on the left, and the other is the white on the right. The white part represents the original presentation, while the gray part stands for the blank part of the screen. Be sure, if we play a presentation on a HDTV it will not be displayed like this, but two black (or gray) bars (known as letterbox bar) on the left and right sides of the screen. Here, we just concern the layout. What we should do now is to add something to replace the gray part. Before I experienced PPT to flash conversion tools, I have no idea what is appropriate for the little gray.

Articulate Presenter, Wondershare PPT2Flash Professional, FlashPoint and Pointecast Publisher are powerful tools to convert PPT presentations to flash-based ones. Articulate has said they would announce a new version of Presenter that supports PowerPoint 2007 before April, but until now, it’s not available. Wondershare PPT2Flash Professional and Flash Point have released the new version that support PowerPoint 2007, and they do able to convert .pptx files, but only PPT2Flash Pro can do it well (most SmartArts converted by FlashPoint are in terrible condition). Here, take PPT2Flash Professional for example to show how to use this kind of tools to solve our problem.

Firstly, after installed PPT2Flash Professional (the version I installed is 4.1.0 Beta, it’s available for free), open the presentation in PowerPoint, we can find PPT2Flash on the menu bar, click the cascade menu, choose Player Templates, in Player we could see the player’s frame. In the full style mode, there is a panel at the left (there is another template that display the panel on the right) of our slide. It is exactly what we need. With this panel a 4:3 presentation becomes a 16:9 presentation (maybe not exactly 16:9 proportion, but much better).

Then, let’s have a look at what we have on this panel, Company logo; Author Info, which includes E-mail, Bio, Name, Photo; Toolbar, including Flash Title, Attachments, Notes; Control Bar. Users can manually set which items will be displayed. After personalized the player template, publish the presentation, we get a flash presentation with 16:9 aspect ratio.

Now we can play the presentation on 16:9 wide screens by setting its aspect-ratio control to Stretch or Full.

PowerPoint 2007 SmartArt-Share Your SmartArt

SmartArt can be said as the coolest improvements in Office 2007, especially in PowerPoint. Yes, it is cool! Any plain text and bulleted items can be converted to vivid diagrams and graphics. Before Office 2007 had been launched, it is difficult for start users to make impact graphics or diagrams without the help of graphic design gurus. Things are different in PowerPoint 2007. Even beginners can easily develop professional look flow charts, hierarchy structure diagrams, and relationship graphics by themselves.

Since processes, concepts, hierarchies, and relationships can be illustrated in text, why we need SmartArt graphics?

SmartArt visualizes concepts and ideas that might not be efficiently explained with plain text. SmartArt can be customized to coordinate with your presentation.PowerPoint 2007 allows you turn the bulleted text from the early version PowerPoint presentations to dynamic graphics by one click.SmartArt graphics may clarify you presentation for better communication and understanding of the content.

Now, please allow me to introduce you some basic knowledge of SmartArt.

There are seven types of SmartArt including, List, Process, Cycle, Hierarchy, Relationship, Matrix, and Pyramid. By names, it won't be hard for you to figure out which type you will need under specific situation. After you applied a SmartArt graphic, you are allowed to change its theme and style by few clicks. PowerPoint 2007 allows you to convert bulleted text to dynamic SmartArt graphics. I built a flash-based tutorial about how to convert bulleted text to SmartArt graphics on this blog.

After you created those professional looking presentations, you may want to put them on your web site to show for your customers. Since PowerPoint presentation does not support web delivering very well, it comes to be the biggest obstacle to improving the accessibility of your presentation. Three solutions, one is provide a download link of the presentation, the other one is outsourcing a flash professional to make a flash-based presentation, and the last choice is convert PowerPoint presentation to Flash movie than upload it to your web site.

It's obvious that the first solution costs less than the other two. But this approach challenges your customers' patience. Many of them would not download and have a look at your presentation unless they are highly interested in your products. Your customers will probably prefer your second solution, because for them, it is time saving and intuitive. For compensation you pay more money on this approach than others. Then, how about the third choice? As for as I know, only two companies have announced that their products support PowerPoint 2007, which are Wondershare PPT2Flash 4.1 and FlashDemo FlashPoint. If you need to make presentations frequently, the third solution must be the best choice. You may download and learn more about them by visiting the links on Resource Box.
