Chapter 7. Rendering Your Projects

 < Day Day Up > 

So, your production is finished, and it's time to render your video and send it off. In years past, this was the time when your knees really started shaking, because rendering your file involved multiple obscure parameters such as GOP order and M and N values presented as life-or-death decisions in your video editor.

Recently, software developers recognized that most key compression decisions can be reduced to templates and presented in plain English. Unfortunately, just because a video editor has a template doesn't make that template right for your project. Some editors implement bad decisions, such as using nonsquare-pixel output resolutions (explained later) and some simply choose poor output parameters, such as resolutions that are too small, or data rates that are too high.

For these reasons, you must understand compression basics to guarantee producing top-quality files. To address this, I'll cover some basic concepts first, then describe how to produce video for specific uses such as distribution via streaming or for desktop playback and how to produce files that you can import into a DVD authoring program.
