YouTube is continuing to pile resources into its TikTok and Reels rival. The updated creative tools look pretty useful too, though ultimately they don’t differentiate that much from what their rivals offer. “Collab” is a new tool for recording a new Short to go side-by-side with existing YouTube or Shorts videos and is rolling out initially in YouTube's iOS app. Other new features include a Q&A sticker and previews of livestreams. Worth investigating.
