One of my goals in learning graphics development was to immerse myself in the understanding of computer graphics starting with a core mathematical foundation, specifically linear algebra. One of the techniques that I felt would be beneficial in achieving this goal was to simply gather any lectures that I could find (specifically good ones) and extract the audio and import into my IPod so that I could have something to listen to when I am driving. The core lectures that I found were the following:<\/p>\n
The first part was to acquire all the videos first. The ITunes education podcasts were easy downloads (MOV). The trickier videos were the Youtube specific videos. For Youtube videos, I downloaded a plugin for Firefox called DownloadHelper. I queued up the videos that I wanted to be downloaded and let plugin rip. Most of the files were of the FLV format which is a flash derivative.\u00a0 I downloaded an open source application called \u201cHandbrake.\u201d This is a fantastic tool that allowed me to queue up a batch of files to transcode to an easier format like M4V.<\/p>\n
Once I had all the video files, I loaded them up into Adobe Premiere Pro and exported the audio clip as MP3. After that, I just downloaded all of these lectures into my IPod and I have been listening to them in order since. Also, I purposely did some book keeping with the filenames so that these lectures would play nicely in order. Essentially, I gave the files a unique prefix specific to the type of lecture and then appended a triple digit to designate the order of the lecture. For instance:<\/p>\n
hurst_001_intro_part1_mobile.mp3
\nhurst_002_intro_part2_mobile.mp3<\/p>\n
This designated the computer graphics lectures given by Wolfgang H\u00fcrst at Utrecht University so that they would be sorted in the correct order.<\/p>\n","protected":false},"excerpt":{"rendered":"
