[edit] Meaning of "Make video certain quality" option in Thoggen
When ripping a DVD in Thoggen you can either specify a size (i.e., 700MB so as to fit the file on a CD)... or you can "make video a certain quality".
If you pick 'make video a certain quality' then you tell the encoder how much quality you're willing to give up whilst encoding. The encoder will then output a file that has the quality you desire, but you have no control over the final output size or the average bitrate (which will depend a lot on the input, e.g. what picture size it is, what type of film/how much movement etc.). [1]
The "quality" range to select from is 0 to 63, where 63 = highest quality. As of version 0.6.0 the meaning of these numbering choices are ambiguous to the user. It has been suggested that for quality, values 0-39 = 'Very Low', 40-49 = 'Low', 50-59 = 'Medium', 60-64 = 'High'. [2]
Perhaps the programmers "attempts to hide the complexity many other transcoding tools expose" (as quoted on the article page) went a little too far with the setting-quality feature. The user is left lost, albeit a simplified lost.
