Video: Learn How to Type Faster in Step 3


Warning: Undefined array key "layout" in /home/bateeqjg/public_html/news/wp-content/plugins/wp-about-author/wp-about-author.php on line 94


Feeling the urge to learn something new, I decided to discover what it takes to produce a video and host it on Youtube.com.
After brain storming some ideas and watching videos to see what was out there, I finally decided upon making a video tutorial on how improve one’s typing speed.
Here’s the result.

“Learn How to Type Faster in Step 3 ” is my first video that I ever made and I learned a lot from the whole process. It took about half a day to complete but that was due to the fact that I had to research what software to use. A few rules that I found along the way are to are

  1. Get help writing subtitles because they take a longggg time! Unfortunately for me, the auto-caption feature failed with an error message of “Machine Transition Failed”. So that left me manually writing the subtitles by hand. I spent 2 hours writing subtitles for this 14 minute video, and the worse part is I could only insert 8 minutes worth of subtitles into the video because the on-line subtitle program I was using(captionTube) crashed every time after that point.
  2. Upload then do something else. It’s going to be a while get all 50MB+ of your video onto youtube.com. My upload time was about 1 hour.
  3. Don’t record everything in one take. It’s better to record multiple takes of a segment, then join the best parts into one long video.

For those wondering, I only used free-ware software for this project. Here’s a list of what I used.

CSS reference in JSON

Hey everyone,
I just want post a link to a JSON file that I made as a CSS reference. It’s slightly invalid JSON because it includes functions but that shouldn’t be a problem unless you’re using ajax to transfer the file for some reason. This file was used to make a random css generator and worked out quite nicely.

File: CSS.JSON
Purpose: To provide a JSON lookup for the css properties.
Limitations: Using CSS Version 1 and 2.
Example code

...
        "white-space": {
            "info": "Specifies how white-space inside an element is handled",
            "cssVersion": "1",
            "unitType": ["normal", "pre", "nowrap", "pre-wrap", "pre-line"]
        },
...
