CCCC Online Tutorials

The Cajun Clickers is creating on line tutorials for its members. Since we are a Windows-centric club, I’ve developed a workflow for making relatively small wmv format video files. They are full size 640 x 480 resolution to maximize the readability of small menu items in the program being demonstrated. The video files are approximately 1.5 MB for each minute of video. I am using the free open source screen recording software Camstudio  (http://camstudio.org/ )

 

Here is a 56 MB, 36-minute online tutorial on creating online tutorials. It explains everything you need to get started. (Firefox users, right click then ‘save link as.’

 

Here is a MS Word file (camstudio-settings.doc) that details the Camstudio settings I used for these videos. Camstudio often has an audio/video synch problem. I think I have found settings that eliminate or reduce this greatly. I've recorded up to 9 mins with no problems. The best technique seems to be to record short (5-7 min) segments then edit them together.  Use the settings shown in this file to get the best results.

 

My workflow is as follows:

 

  1. Record a 640 x 480 window of the computer screen and commentary via a mic connected to my soundcard.
  2. Save raw video from Camstudio as Microsoft video 1 based AVI files.
  3. Edit AVI files in Sony Vegas and render as 200 Kbps wmv file. The resultant videos are 640 x 480 and are approximately 1.5 MB per minute of video.
  4. It is also possible to edit and render in Windows Movie Maker, but wmv files thus created will be around 1.8 to 1.9 MB per minute, rather than Vegas’ 1.5 MB per minute.

 

Here are some demos. These are “rough’n’ready” Blender 2.49 tutorials. (Firefox users, right click, save as)

In late 2010 we developed an alternate workflow for creating tutorials. Clickers member Jack Giammerse, Jr. has a $150 DXG-587V Video Camera, which shoots 1080P MOV H.264 files. Jack downconverts these files to 720P WMV files using FREE SuperC software. He then routes the converted files to me via Dropbox I then edit these with Sony Vegas 6.0. We have found that you can shoot an LCD monitor screen and even in the 720p files you can read the menus clearly!
