EDLD5366 Course Reflections

I can safely -- and confidently -- say that this was the class that I enjoyed and from which I learned the most. The readings and topics that fascinated me the most were Yearwood's Basic Design Principles (2009) and Basic Elements of Page Design (2009). The concepts of Contrast, Repetition, Alignment, and Proximity were all new to me in this context. Who knew that movie posters and other print materials contained so much information that are invisible to the naked eye? Posture, colors, font size and style (who knew that serif was easier to read in print?), straight lines, symmetry, placement, white spaces... taken separately, these seem mundane, but use these to analyze material and one will be surprised at how much can be revealed. After reading these, one could argue that design is not only an art, but also a science.

Another topic that sparked my interest is Bloom’s Digital Taxonomy (Churches, 2007). It lays the groundwork for teaching others how to use technology in the classroom, and considering how every teacher is familiar with Bloom's Taxonomy and how much they adhere to it, buy-in is almost a given. 

This was also evident in the discussion board. It was easy to see that everybody learned a lot from these topics, and the level of engagement reflected this as well. We all learned a lot from the readings and from each other not just with the critic activity, but also in other discussions. I appreciated everybody's constructive criticisms and immediately applied it to my teaching aid.

Like most people, I have never tried, much less had to, design a personal logo and never even considered myself anywhere near what Goldsmith calls, "personally branded" (2007). Nevertheless, this concept of personal branding fascinates me and serves as a reminder that we as educators, whether we like it or not, are now living public lives and that we can take measures to manage this fact and use to our own advantage. Being an avid supporter (and endorser) of Free and Open Source Software or FOSS, I used Gimp to create and design my logo because Adobe's PhotoShop has always been inaccessible to me since I had no use for it and could not afford it anyway, even if I did. It was a humbling experience. I say that because this program is too complicated. No matter how many times I viewed tutorials, no matter how hard I tried to use effects and enhancements, my logo came out rather simplistic. In spite of this, though, creating a logo that reflected my personality and some of my core values was satisfying enough.

The animation project was another interesting project. Time consuming as it was, it was utterly rewarding seeing the end product "move" and make sounds. After conducting some research on product reviews comparing Stykz and Scratch, I first settled with the former. It was easy to use -- just clicking and dragging the stick figure's joints and/or whole body, but found it too unenticing. I imagine students would agree with that sentiment. Then I tried Scratch. It was also relatively easy and it had the added benefit of being a lesson on coding using building blocks. That clinched it for me. After all was said and done, I came up with a very simple animation that consisted of a female dancing to the tune of a guitar strumming. I am actually excited to show this to my fellow teachers and with practice (and the help of the video tutorials) I think we could include animation as a teaching medium/strategy in my campus.

In terms of being laborious, the newsletter was the most intensive assignment in this course. I have worked for my school newspaper in high school, but I was neverinvolved in the layout design part. It also did not help that my word processor (OpenOffice's Writer in this case -- again, being a FOSS supporter) acted like it knew what I wanted to do yet the words never came out right. Words would nbot spill over to the next page whenever I needed them to, yet they did not hesitate to spill over to the next column when I did not need them to, even when there was still a lot of white space in the previous column. I was almost ready to surrender and publish a one-column newsletter... and that happened more than I would like to admit. Luckily, after three complete overhauls and fresh starts, I was able to master the Frames and Columns features. When I saved it and opened it again later, the words were all over the pages and some were even hiding beyond the pages. Needless to say, it just meant starting over. On my fourth attempt, and before I saved and closed it for later, I hit "Export to PDF." It came out fine, but the white spaces were not acceptable by Yearwood's standards (2009), so I inserted black separators, which inadvertently made a mess of the words again. To cut the story short, I was able to come up with my newsletter after numerous attempts and with nary a tear shed nor a computer broken.

As one can tell, I was able to accomplish a lot by trial-and-error. All these tasks were new to me. On top of that, I do not really consider myself a particularly creative person. I am more of an editor-critic of other people's work. This course posed a real challenge -- nay, real challenges week after week and task after task. The video tutorials helped too, but I also had to try it for myself since I am more of an auditory-visual-kinesthetic learner rather than relying on one modality. Lucky for me, this course included a lot of those resources and opportunities instead of relying solely on text or one modality.

To sum it all up, the skills and concepts I have learned in this course would definitely play a big part in my career as a Campus Technologist and as a lifelong learner. Now, more than ever, I feel more prepared to train my colleagues, I feel more confident that I can use programs that have intimidated me before, and I have gained new knowledge that have enhanced my technical know-how.

Windows Live Movie Maker
Windows Live Movie Maker is a free and simple video editing program from Microsoft, and is a part of their Windows Live Essentials suite. It appears similar to, and does the same things as, the now-discontinued Microsoft Photo Story 3. The user interface, or UI, is split between a full-featured toolbar (similar to the ribbon interface that other Microsoft programs have), a video preview pane, and a content pane.
Operation is simple. After choosing content, it appears as clips in the content pane in what looks like a storyboard. You can drag and drop clips to order them and can mix and match videos with photos. From here, you can proceed manually and discover some of the application's more advanced features, or use the program's “AutoMovie” feature, which makes a final movie that includes a title, credits, and simple crossfade transitions between each clip. If you so choose, it can also fit the length of the video to a song or other audio track. When the AutoMovie process is complete, you can edit the title and credits as well.
Manual editing is also as easy and simple. You can do things like add captions, which come complete with optional special panning effects, custom fonts, transparency settings, and even cusotmizable start and end times. The program comes pre-loaded with transitions – for video clips as well as photos – and you can choose among more than 60 different transitions, and even edit their duration. For photos, you can set how it pans and zooms while onscreen, a la Ken Burns's documentaries.
Windows Live Movie Maker also offers 20 visual effects, and if you prefer, you can use two or more on the same clip using a Multiple effects tool. Visual effects include brightness controls, grayscale filters, horizontal and vertical mirror images, and more.
Additional editing features include 4:4 and widescreen 16:9 aspect ratios for your project, fine-tuning audio tracks, rotating clips, editing the audio mix , and other useful functions.
After finishing your project, the program offers ways to share it such as posting to YouTube (which is easy if you already have an account there. All you have to click the YouTube button, fill in some information about the video, and then click Publish. Windows Live Movie Maker will process the video and then upload it to YouTube. Other sharing sites are available, such as Facebook, SmugMug, Picasa, PixelPipe, Multiply, and Drupal, but you have to download plug-ins for each site.
Another feature of Movie Maker is creating and uploading an HD movie, and you can choose between 720p (1280 x 720) or 1080p (1920 x 1080) resolution – which is a high-quality video, with an 8 Mbps bit rate, and is the highest resolution currently on HD televisions – so people who view the movie online will have that option. The resulting movie is in the Windows Media Video, or WMV, format. Other formats available include 720p HD at 6 Mbps, 480p widescreen (720 x 480) at 3 Mbps, standard definition 480p (640 x 480) at 3 Mbps, portable device or phone (320 x 240, 1.7 Mbps), a smaller file for email or instant messaging (320 x 240) at a significantly lower bit rate of 291 Kbps. However, as previously mentioned, the only file type supported is WMV. One caution though, YouTube doesn't allow you to use copyrighted music in the videos you upload, so please be careful in choosing your audio soundtrack.
Movie Maker also lets you burn a DVD, which creates a local 720p WMV file with a bit rate of 3 Mbps. After the file is created, Windows DVD Maker launches and starts a new project with your video as the file.
This program is compatible with both Windows Vista and Windows 7, and the application provides support for additional video formats--including QuickTime MOV and QT, AVCHD, and various MPEG-4 formats, but these are available on Windows 7 only, as Windows 7 provides native support for these formats. Sadly, H.264 output, which is the current and preferred standard for video compression by professionals. Also, Windows Live Movie Maker does not run on Windows XP, but previous versions of Windows Movie Maker is available for this version of Windows.







ZS4 Video Editor
The other highly reviewed program I picked, Thugs @ Bay's Zwei-Stein Video Editor, now renamed to just ZS4 Video Editor, is highly regarded by video professionals on the free and open source side. That being said, this program is not for beginners as it is very complicated and confusing, but one can refer to the tutorials posted on http://www.zs4.net/tutorials. After importing a file, it appears on the Import panel, where you can preview video and audio using the playback controls below the waveform display. To select a section of a video or audio file to add to the project, you can either draw the area with the mouse, or use the start/end selection buttons located to the left of the playback controls. The program has what are called “dig” buttons to the right of the play controls. The manual details that, “the dig button (single heart) can be used to save one or more selections (digs) for future use.  These will still be available the next time the file is loaded into ZS4.  Use the next dig button (multiple hearts) to navigate between digs.” A feature that makes this program really advanced but hard to use is that media are arranged in descendant/child layout, where the main track is called the “MediaMixer,” and all tracks are descendants thereof, but each child can have their own descendants as well. Like I said, it becomes highly confusing as it can become convoluted if you use this feature. However, the “Project Tree View” helps in this regard by giving you an easier snapshot.
Using effects is not any easier. To change the settings for an effect, select the effect in the track treeview and click on the "current" tab, next to the arrangement (track display) tab.  There will be a large representation of the current frame with several drawing tool toggles below it.  Click the toggle you want to use and then use the mouse to draw on the frame.  Every effect will have different toggles allowing you to draw the affected area, color pick, set rotation angle, and more depending on the effect. You can also manipulate the variables directly using either the “Vars Tab List View” or the variable settings tab.
When finished with your project, get to the export tab, by either clicking on the export icon on the appropriate track or selecting the appropriate track in the tree view and click the track button at the top, followed by the export tab. To save a JPG, BMP OR PNG still image (PNG preserves transparency), type a file name in the output-file text entry field followed by a an extension of .jpg .bmp or .png.  It will be stored in “home/t@b/export/todaysdate” on Linux, or “C:\My Documents\t@b\export\todaysdate” on Windows. To export only audio, use a .wav extension.  If the export video button next to the text entry field is depressed, be sure to un-depress it, or else export will not work. To export video, either don't specify an extension (AVI is default) or use .zsv for exporting MPNG files (if you use Windows and have no decoder for this format.  Doing so, ZS4 will be able to read the file, bypassing the default program, Windows Media Player. To specify a different folder to save the file to, you might use something like this under Windows: “C:\My Documents\My Videos\My Stuff\myvideo” or on Linux “/home/me/whatever/video,” or you can use the browse button to select a location and file name. The default save location for video and audio is My Documents or home. The audio and video toggles are used to mute video or audio output in the exported file. The quality slider should NOT be set to 100 and should potentially not be set to anything above 0. For exporting video, there are four choices: IYUV/i420 (uncompressed format), Motion JPEG or MJPG (this is included with libavcodec which comes with mencoder), MVJP, OR MPNG.
Reflection:



My computer runs Windows 7, so my choices were limited to the ones that are available for this operating system. Another limitation is good user reviews if only for two reasons: I want to use something that works, and I do not want to download a virus or other malware onto my only computer. After an exhaustive Google search, I narrowed my choices down to Microsoft's own Windows Live Movie Maker and Thugs @ Bay's ZS4 Video Editing Software. I must confess that I had a really hard time using ZS4, especially after using the user-friendlier Movie Maker. The user interface (UI) and the options proved to be too overwhelming for me that I cannot imagine myself using it beyond this assignment. On the other hand, Movie Maker is a breeze to use. It also helped that I used another Microsoft product with a similar UI for the previous week's assignment, Microsoft Photo Story 3. Its limited file type support did not hamper my usage as I am an avid Microsoft user, with Windows 7 and Zune loaded on my computer and the hardware to match. For my use too, the other formats, aspect ratios, and availability of effects and transitions is not really a big requirement. Rather, my priorities would include ease of use and compatibility with the school's computers that run Windows and corresponding file types.
From this point forward, I think I will add Movie Maker to my arsenal of digital storytelling tools and instructional technology as well as tell my fellow teachers about it. It can also prove to be handy when it comes to “Meet the Teacher Night” as well as PTO meetings to make video presentations about the years past or a preview of the year ahead. Its ease of use and handy “AutoMovie” feature will probably win my fellow teachers, especially those who are easily intimidated by technology.
