Mini DVD to DVD video conversion preserves 100% of the quality on the original mini disc. Like full-size DVDs, Mini DVDs use the MPEG-2 encoding format. This means that the video is heavily compressed, and is therefore an "end-format" type of video (as compared to raw DV video, which can be edited).
For this reason, if you copy Mini DVD video to your computer, it is not advisable to edit it without a software program that can natively edit MPEG-2 files without re-encoding. If you want to edit your video, DV is still the best choice.
A Mini DVD can hold 1.4 GB of data, which is approximately one-fourth the capacity of a regular DVD. Most Mini DVD camcorders offer quality settings of 20 minutes (XP), 30 minutes (SP), and 60 minutes (LP). Longer settings may also be available on some camcorders, but keep in mind, the video quality suffers as the recording goes longer. We advise that camcorder users select the XP or SP setting whenever possible, which helps greatly when we are converting Mini DVD.
Single-sided dual layer mini discs are now also available for some Mini DVD camcorders. These discs double the length of the recording time, but we can transfer Mini DVD video from them as well.
