I was exploring Adobe’s website for Premiere and discovered Smart Rendering. Smart rendering is, essentially, media optimization before and during editing. It allows you to create better quality output by avoiding recompression where possible. This isn’t a new feature, it first showed up in Premiere CS6. But, if you are outputting MXF files, you’ll need to turn it on.
Smart rendering cuts down on the processing of exporting even more by doing a bit more work up front. Any smart rendering workflow you can add prior to exporting will speed up your exporting process even more than improving hardware and working with optimized media.
Kevin Monahan, from Adobe, summarized the steps of Smart Rendering:
You can also capture this footage natively to these codecs while shooting with certain cameras or recording systems (Atomos devices, etc.). It turns out that a lot of recent camera formats are available for smart rendering, including certain flavors of XDCAM.
Smart rendering works only if the source codec, size, frame rate, and bit rate match the export settings. Smart Rendering is supported for both MXF and QuickTime wrappers.
While you are editing
Kevin adds: “I should also point out that it is a much nicer editing experience when cutting with ProRes or the like, over Long GOP footage like H.264 or AVCHD. You drop fewer frames, and can view in a higher resolution with these intraframe codecs. You can even create proxies for them if you have an underpowered computer system and need better fluidity when editing.”
Here’s a link that explains other ways to speed rendering and export.
Codecs in an MXF wrapper that support smart rendering
NOTE: To activate smart rendering for codecs in an MXF wrapper, check the “Enable smart rendering codec” option found under the Video settings tab of the preset.
Codecs in a QuickTime wrapper that support Smart Rendering:
NOTE: Smart rendering for QuickTime codecs is automatically enabled any time the source settings match the export settings.
