Free And Portable Image Editing Software

February 27, 2012

The TLTC frequently assesses new software. We post parts of our internal reviews on our blog, but we do not necessarily endorse the technologies presented here. Please use this post for information only. The TLTC only supports technologies listed in our technology toolbox.

I’d like to present another free and also portable image editing software that I tested and found very easy and friendly to use. PixBuilder can match to any level of needs, whether you need to do small changes to your images or for someone who wants software that can make more serious and advanced corrections.

Another thing that I really like is that PixBuilder requires low memory so you can load it on a USB drive and run it from any desktop.

PixBuilder works with high resolution images and support layers, an important feature for anyone who’s halfway serious about editing images. PixBuilder’s uncomplicated interface is familiar and intuitive, with menus across the top, a toolbar down the left side, and a set of panels down the right.

Main Features
  1. Image resizing, rotating, and crop function.
  2. Brightness/Contrast, Color balance, Levels, Hue/Saturation, and Color fill.
  3. Auto Contrast and Auto Levels.
  4. Built-in high quality effects: blur effects, sharpen effects, dithering, and more.
  5. Flexible selection management functions, such as transparency masks, magic wand, different lasso tools, single column selection, color range function, and the gradient color transition effect that gives you the ability to draw complex raster shapes and apply effects for complex areas.
  6. Layers concept makes your work more effective and efficient.
  7. Text layers with drop shadow.
  8. A full set of brush-based tools, such as the stamp tool, healing brush, replace color tool, and others.
  9. Built-in shapes drawing tools (rectangles, circles, and lines).
  10. Free transform and Selection transform.
  11. Save with preview.
  12. Support of image scanners.

Computer based training example

February 17, 2012

I had an experience with computer based training while I was taking a graduate course on educational technology. One of our projects was to evaluate a unit of online training. I love to cook, so I decided to find one about the science and practical skills behind cooking. Searching the internet I found a site called Rouxbe. The first lesson I tried on their site was free, and it convinced me to sign up for more.

Everyone knows the basic ideas of how to fry food. You put it in a pan, heat the pan, and voila. The problem is that so often that the chicken or steak or potatoes you’re frying ends up sticking to the pan and your food ends up as more of a hash than anything else. The lesson I tried was on pan-frying and it started by talking about the theory of how food reacts to a hot pan and why oil is necessary. It presented a series of videos that were professionally narrated with an excellent voice actor. These videos showed me exactly how to determine when to add oil, how much oil to add, and when to add the item to be fried – chicken breast in this case. The sound was incredible – you could hear the splash of the oil and the sizzling of the chicken.

It showed how to not do things as well by demonstrating chicken added to a cold pan or put in a pan that is too hot. It ended by delivering a self-test that included video and audio samples and asked questions about them. For example, it showed water drops being added to pans with different heats and asked which pan was at the proper heat.

The lesson also included recipes based on the technique it taught and a forum where you could ask a Rouxbe chef questions (and they were actually around answering the questions on a daily basis!)

This demonstrated a high water mark for CBT – professionally produced, using sound instructional design, and choosing a medium that really worked for the material being presented.

Microvideo at Red River College

February 17, 2012

Principles of Microvideo

Video in teaching and learning is becoming more and more important. We only need to look at YouTube to see the huge proliferation of online video training pieces – both good and bad. The problem we face is how to help the hundreds of instructors at our large College develop the videos they need without massive investments in production facilities.

The TLTC has been working towards the concept of microvideo as a sustainable solution for our College’s instructors to produce simple and effective video. Here are the principles that we developed to guide instructors in creating these microvideos:

1. Single Topic Short Videos

People have short attention spans. Long videos will lose their attention. Break your videos into small chunks of 5 minutes apiece that cover a single topic.

2. Many Takes One Shot

There can be many takes, but the final version must be one shot. If there is a problem during a take it is fixed by doing another take until it’s correct.

3. No Editing

The video will not need to be edited once it is shot – video and audio must be recorded at the same time. If it’s not right, reshoot.

Do not put info into the video that will likely change. There should be no references to the textbook used, the course the content is going into (because it could be repurposed for another course), the sequence of the videos (don’t refer to yesterday’s video, make each video standalone), the module or lesson that the content is going into (because its location could change), or the day on which the video is being shot.

4. Plan Ahead

Planning saves time. Prepare an outline and practice out loud what you’re going to record before the shoot. Try to shoot more than one video at a time. Find a time and location where you will be undisturbed. If you need help from other people ask for it well in advance.

Types of Microvideo

Type of Video Details Ideal Length Resolution Resources Required
Talking Head Introduction or brief lecture. Many takes, single shot. No editing. ≤ 5 minutes ≥ 320×180 or higher webcam & mic, adequate lighting, quiet space
Screen Capture Demo of actions on a computer screen – single concept. No editing. ≤ 5 minutes ≥ 640×480 or higher Screen capture software (camtasia) & mic, quiet space
Interactive Flash Video Built using off the shelf tools. No customization. ≤ 5 minutes ≥ 640×480 relevant software, mic, quiet space
Document Camera Single concept demo of ‘thing’  based operations – math, tools etc. Shot from above via camera and stand. No editing. ≤ 5 minutes 1280×720 (720p) document camera & micadequate lighting, quiet space
Location Shoot Single fixed shot or handheld camera while narrating. No editing. ≤ 5 minutes 1280×720 (720p) HD webcam, wireless  mic, adequate lighting, quiet space

Following these principles will help you to create simple but effective videos that you can put online for your students. It’s easy to get distracted from true microvideo, however. For example, if you’re creating longer videos (say 10 minutes), once you hit that 9 minute mark and make a mistake it becomes a much harder thing to say that you’re going to restart the video from scratch. Soon you’ll start thinking that some quick editing will solve your problem, and then that turns into a much longer process overall. Sticking with short videos makes a big difference in executing the “many takes one shot” principle.

If you have any questions about the technologies we use, please contact LEARN Support at learn@rrc.ca for more information.

I’ll post more soon about some of the solutions we’re looking at to host video in the College.
