I was recently asked about my opinion on the best export settings for a video that will be placed inside of an eLearning course. Specifically, if the quality and size of the completed eLearning should influence the quality and size of the video’s quality and size? As we discussed the matter it was also expressed to me that as far as audio compression and quality are concerned, there isn’t a whole lot of information readily available to eLearning professionals. Below are some of the ideas I had.
Let me start by answering the more specific question about compression before or after inserting into the eLearning software. As a general rule I export videos in their highest quality possible (to a standard being 1080p with an audio bit rate of +100kbps and a sample rate of +40kHz) for this reason: it is better to have something large that in the end needs to be compressed than to compress it at the beginning and find that it is too small/choppy/gross and cannot be “blown up.”
