|Knowing the best rendering strategy can save time.|
Whether you edit on Adobe Premiere Pro, Apple Final Cut Pro or Avid Media Composer, your video needs to be rendered, when it comes time to archive your video. Rendering allows you to contain all of the video layers in a single video stream.
Since most of what I do has to get out of the system as a file at some point, I prefer to render my topmost track. Not only does this prepare for an export, but rendering the topmost track, means the video is re-compressed only once. If I render a lower track first and then the track above it, the system has to compress the composite twice.
|Many choices available for export.|
Technically, all export modes render on output, the difference is where they put that render. If you plan to export the video on multiple occasions, your best bet is to render the top track of the sequence first - this will eliminate more than half of the time to export out same as source.
Expert Render may be fine for playback or when outputting to tape, but it doesn't help when exporting, no matter what type of export you use. Whenever I need to encode my video for review or delivery in some other video format, I always export out of the editing system as a Quicktime reference movie. This is the quickest way to get the video out in its native quality. It also lets me use software that specializes in encoding video, such as Sorenson Squeeze.
|Render All Video Effects.|
The good thing about exporting a Quicktime reference, while rendering all effects, is that it saves the renders as precomputes. This means that going forward, you are working with a rendered sequence. This feature is also core to the batch rendering multiple sequences tip in Avid Editing Tips and Tricks - Part V. On the other hand, if you export as "Same As Source" or some other codec, the system has to render the composite as it writes the frame to the exported file.
The rendering and export strategy you choose can save a lot of time in your digital video editing workflow. Choose the strategy that works best for what you need to accomplish.
