X has revamped the tool it uses for uploading and publishing videos. The new composer has a more focused layout and editable captions to creators, with the help of Grok, the AI assistant that is available inside the company’s application. Social Media Today reported the change on October 4, 2026, as part of a series of other video updates X has been rolling out since July.
The new editor, according to X developer Allegra Jacchia, is cleaner, more intuitive and much easier to use. The main focus of the release is captioning, although the new layout applies to every video that passes through the composer.
X has revised its video uploading and posting process a number of times this year, and this version is just another iteration on the same theme. The change adds more focus to the composer, which Jacchia described as cleaner and more intuitive than before.
The report does not describe the new screens in detail one after another, so the details of the controls on each are not specified. What it does say is that the new editor puts more emphasis on the in-stream tools and functions available for editing video. These tools are contained within the application, allowing the creator to work on a clip in X, rather than editing it elsewhere.
Captioning is where this update does the most. Creators can edit captions manually within the composer, or request Grok to correct them (Grok can also be used for translation into another language).
Manual caption editing and Grok correction exist side-by-side (a creator can correct a single word manually, or hand the whole caption over for correction). The article does not indicate how many languages Grok can be used for, or how accurate the corrections will be.
The translation capability builds off of work X did earlier in the year, with a caption tool that could handle multiple languages (when X released a major video editor update back in July, that update included multi-language captioning tools; the latest composer includes Grok, for use on both caption correction and translation).
The composer update follows several video features in the past months. First, in July, X released a new video editor and recorder interface in iOS. Among features was multi-language captions, green screen recording, and added the new tools in an overlay for more creative options when posting videos.
X’s head of product, Nikita Bier, highlighted the addition of new options to the updated player as a specific focus. He also added that X had “plenty more updates coming to the video editor in the coming weeks.”
In August, X added video overlays for iOS users, where people can place text and emojis over a clip. Jacchia posted a sequence showing how it works, while Social Media Today described it as a small update in the big picture of video editing features but also brings X’s tools closer to what other social apps have.
The October composer is a follow-up to both of those releases. Taken together, the July editor brought in captions and green screen recording, then with the August update, overlays were added. This latest release reworks the layout and includes Grok into the caption process.
Video uploads are only part of what X has been updating; on Sept. 23, X launched an updated livestream API. The company noted that the tool was rebuilt from the ground up and enables third-party video platforms to manage its streams, giving the creators more tools to manage their broadcasts.
The entire list of tools is detailed; it includes managing persistent RTMP streams, creating, publishing and monitoring broadcasts, scheduling broadcasts, reading and responding to live chat, and moderating chats, with options to mute and remove viewers. The creators can go live with various streaming providers.
In July, X had also launched an updated livestreaming command center within its Creator Studio platform. It was meant to help creators schedule and run their live broadcasts more easily in the app. The new API adds to this effort, and Social Media Today noted that the combination could result in a significant increase in X’s video streams.
The report ties the composer to a goal X has long emphasized. Like any platform, X seeks to incentivize original content creators. Native creation tools can help there, since they enable posters to generate more original content, without relying on edits they’ve made and uploaded to other apps.
That effort’s incentive component was announced in April. Bier announced updates to X’s creator revenue share program, saying they’re experimenting with new tools to identify the original authors of content and give a cut of revenue to each. He argued that the program should reward the effort that went into something, not just the account that helped a post travel furthest.
Bier also noted that all aggregator accounts had their payouts reduced to 60% in that cycle, with another 20% slated to be cut in the next. According to Social Media Today, payouts are based on cumulative impressions from verified users, and that X had no way to differentiate types of engagement at the time. That means reposts may have earned more than thoughtful original posts, a gap the changes were intended to fill.
Other platforms have implemented similar steps. Instagram announced efforts to combat aggregator reposts in 2024, including removing reposts from its Explore page. In March, Meta announced that user time spent watching original Reels approximately doubled in the second half of 2025 compared to the same period of 2024. Social Media Today said X’s approach is more directly tied to financial incentives and less algorithmic than those that limit the reach of aggregator profiles.
X has seen a rise in video engagement over the past couple of years. At the same time, the app has apparently stopped referring to itself as a video first platform, a tagline it adopted in 2024.
The tagline was made by then CEO Linda Yaccarino, who stated in 2024 that X is now a video first platform and that video views in the app have increased significantly. Social Media Today’s July story contended that X hasn’t done much to become a video focused product, and stated that X usage was still a lot below TikTok, Instagram and YouTube.
X has made several initiatives to make video a significant part of the app over the past couple of years. These include a trial of a video tab in the lower functional bar and a slate of deals on original video content. In May 2025, X announced a slate of X Original programming which included celebrity led productions. Social Media Today said that X’s algorithm has sought to boost video posts to increase time spent in the app.
X has introduced captions, translation, green screen recording, overlays and a livestream API in the span of a couple of months, and the composer is the latest of those releases.
There are a few missing details in the provided text. The report does not specify which devices and regions will get access to the new composer, when the update will be available for all users, and how many languages Grok can translate captions into. The July update was mentioned in the context of iOS, but the October report makes no mention of any particular platform.
Those who want to use the new composer should check the applications’ settings for its presence. The report by Jacchia, which is linked to the original article, is the official source of information about the update.
Q 1: What did X change in its video composer?
The update gives the composer a more focused layout and better caption tools. Creators can edit captions by hand or ask Grok to correct them, and Grok can translate captions into another language.
Q 2: Who announced the update?
X developer Allegra Jacchia shared it on X. She described the new editor as cleaner, more intuitive and much easier to use.
Q 3: What does Grok do in the new composer?
Grok is the AI tool built into X. In the composer it can correct captions and translate them into another language.
Q 4: Can creators still edit captions without Grok?
Yes. The composer lets creators edit captions manually, and asking Grok for corrections is an added option.
Q 5: When did X last make a major change to its video editor?
X released a major video editor update in July 2026 with multi-language caption tools and green screen recording. Coverage of that release described the iOS version of the app.
Q 6: What other video features has X added recently?
X added video text overlays for iOS users in August and launched an updated livestream API in September. In July it also launched a livestreaming command center in Creator Studio.
Q 7: Why is X building native video tools?
X is working to incentivize original content creators, and the report says native tools let posters share more original content. Creators then do not have to repurpose clips they already edited in other apps.
Q 8: Does the report say which devices get the new composer?
No. The report does not name platforms, regions or a rollout schedule, so those details are unconfirmed.
