=== Quality and Resolution ===
Video conversion is much more complex than anyone realizes.  Today's web-based video use makes it appear that conversions can be done trivially.  After all, people routinely upload things to YouTube in any format they wish and it is magically converted and looks "good enough".  Packages like MediaFork, Virtual Dub and others make it seem easy to drag-and-drop video and have it simply and quickly converted to another format.

When working with high quality video, the only good conversion is no conversion and it is important to avoid the misconceptions which abound.  You should especially be sure to understand the difference between [[Codecs and Containers|container formats and codecs]], since these are major factors in determining quality of converted video.

Frame rate conversions are the most important to avoid.  It is much easier for conversion software to change the size or resolution of a video than it is to change the frame rate.  Even extremely expensive grid-based computing platforms used for professional conversions may take up to '''1 hour per minute of video''' if a good frame rate conversion is needed.  So, if your conversion software takes a 10 minute video and converts the frame rate "automatically", beware.... it is probably doing a lousy job.
