Every week, Frame.io Insider asks one in every of our knowledgeable contributors to share a tip, device, or approach that they use on a regular basis and couldn’t stay with out. This week, Heather Hay reveals the best way to embody alpha transparency in your Resolve exports.
Sometimes, you’re given a video with an alpha channel (transparency), textual content, or VFX so as to add to the timeline. Resolve does a very good job dealing with these, however the trick is to export your deliverables with the alpha channel nonetheless intact. Let’s head over to the Render web page.
How to export with alpha channel
DaVinci Resolve gives a variety of choices to protect alpha channels, together with Uncompressed 10-bit, Uncompressed 16-bit Float, ProRes 4444, ProRes 4444 XQ, and DNxHR 444 codecs. In my workflow, I sometimes render a Premiere XML/ Quicktime Apple ProRes 4444 XQ (the fourth 4 signifies the inclusion of the alpha channel in a Quicktime file) on the supply decision with handles.
However, no matter which of those presets (or customized settings) you select to render in, you’ll have to verify the Export Alpha field, permitting you to pick out any of the 4444 or DNxHR 444 codecs on the Render web page.
Once you’ve enabled the ‘Export Alpha’ field within the Render web page, you’ll be able to go for a straight alpha or a premultiplied alpha, relying in your necessities. However, it’s vital to notice that conducting a high quality verify of your renders in DaVinci Resolve earlier than remaining supply is crucial. This ensures that your undertaking achieves the absolute best outcomes and mitigates any potential points.
