X Unveils Immersive Video Player to Compete with TikTok
X introduced a redesigned immersive video player that emphasizes vertical, full‑screen viewing on mobile. Announced by Nikita Bier, X’s head of product, the iOS rollout lets users tap to expand videos to full screen and swipe up to move to the next clip — a TikTok‑style interaction. Some users have criticized forced cropping of non‑vertical content; Bier said portrait is preferred and that X will stop cropping vertical content going forward. The update follows X’s global launch of a dedicated vertical video feed last year and accompanies other video and AI moves (including Grok’s text‑to‑video feature). The article notes broader context: recent changes in TikTok’s U.S. ownership and moderation issues that led X to restrict Grok’s image generation to paying subscribers.
A major social platform (X) rolling out a mobile-first vertical video player can shift creator behavior, format standards and competitive dynamics for short-form video — affecting content supply and ad formats across social video inventory.

X launches built-in video editor to boost original content

The editor is initially available on iOS while X’s Android app is still being rebuilt.

TikTok Attribution Source Optimization Aligns Measurement and Bidding
TikTok introduces Attribution Source Optimization for app advertisers, allowing them to select their preferred attribution source (e.g., MMP) to inform campaign optimization. This addresses discrepancies between platform and MMP reporting by aligning measurement and bidding signals. Features include support for Adjust, AppsFlyer, Singular, and upcoming integrations with Airbridge, Branch, Kochava, and Tenjin. Alpha testing with iOS gaming app That's My Seat showed an 18% lift in Day 0 tROAS and 15% increase in billing ratio. The move aims to give advertisers more control as AI-driven automation increases, ensuring optimization uses the same conversion signals marketers trust for performance evaluation.
