Josh Makinda demonstrates how to output or export media (video and audio) from the Blender 3D to preserve the highest quality for production.
Blender Compositing – Output Full Quality Audio/Video from Josh Makinda on Vimeo.
“In this quick tutorial I show you how to output/export your video from blender, after adjusting it in the compositor. We utilise the sequence editor and output audio and video that is at 100% full quality, not degraded at all. It appears many were having trouble with this topic. This is just one of a number of methods I’m sure. The first tutorial in my official tutorial series (approx 4 and half hours) can be found here: mindbites.com/?lesson/?12138-compositing-with-blender”
