YOUTUBE EXPANDS THUMBNAIL EDITING OPTIONS FOR SHORTS

Summary from the TLDR Design newsletter

YouTube Shorts creators can now customize thumbnail frames post-upload with text, filters, and emojis. The option to upload custom thumbnails is not available yet. YouTube says that thumbnails are less critical for Shorts as they are primarily seen in the Shorts feed. However, Shorts can still be discovered through search, hashtags, and the creator's channel. YouTube is considering adding more functionality to Shorts thumbnails in the future, including the ability to upload fully custom thumbnails.
