- [Voiceover] Removing grain or noise…is a fundamental preprocessing technique for keying,…but the grain must not be gone from the final composite.…Here we'll look at three workflows for managing grain.…Now this video is about various grain management workflows…not the denoise node itself.…If you want a refresher on the denoise node…you can go to vimeo and search on denoise tutorial…to find three tutorials by The Foundry.…Let's start by reviewing the uber key workflow.…
You saw this in an earlier movie.…The idea here is…that the green screen is first degrained.…The degrained version goes to the keyers,…who pull just the alpha channel.…The original grainy plate gets spill suppressed…and then color corrected.…Then we copy in our uber key,…do a premolt and then comp it over the background.…So the grain was never removed and the grain stays right…in this data stream right here up to the final composite.…
Okay, that's one workflow.…Let's look at a second workflow,…the remove and restore.…The idea here is we're going to…
