The "Best" recording, weighed in at 55.5MB, while the "Good" recording only took up 15.1MB. The difference in size is significant, several hours of video on a normal hard drive in fact. However, is there a great loss in quality? Of the images below, the one on the left is a snapshot from the "best" quality recording. The picture on the right is from "good" quality. Although JPEG compressed, for these two images I used maximum quality to reduce loss of quality by JPEG compression.
