# How to Post a Video on X > Choose a rights-cleared video, add it through the X composer, review post and download settings, and inspect the published post after sharing. - Canonical: https://fluxgravity.io/guides/how-to-post-video-on-x - Published: 2026-10-11 - Content type: guide X supports video recording and uploads through its app and web composer, with eligibility and upload limits that can vary by account and subscription. Check the current Help Center before preparing a large file. ![Warm FluxGravity social illustration for an X video posting guide](https://fluxgravity.io/images/editorial/guides-how-to-post-video-on-x-editorial-map.svg) *Original page-specific FluxGravity editorial map based on this guide's structure. It is not a product screenshot, account test, or performance result.* ## Check current video eligibility first **Answer:** X's supported file types, duration, size, and account limits can change, so confirm current requirements before exporting a video. X Help describes recording or adding a video in its app and uploading a file through x.com. Its current page also documents different upload limits by account status. Because these limits can change, review the live Help article for your account before preparing a long or high-resolution file. A file rejected during composition may need a supported export rather than repeated attempts. Choose a clip that fits the message and audience. If the clip contains third-party footage, music, or identifiable people, confirm that the rights cover X publication. Check that the video does not expose private information or include a claim that has not been reviewed. - Check current X file and account limits. - Use a file you are authorized to publish. - Keep sensitive details and unverified claims out of the clip. ## Prepare the post text and accessibility **Answer:** Write a concise post that gives context, and review captions, audio, and any timestamps before composing. A useful post tells readers why the video matters and what they will see. Avoid a caption that promises details the video does not contain. If a longer video has chapters or notable moments, X's help notes that timestamps can provide context and help viewers navigate. Verify the time points against the final export before adding them. Check the video on a phone with sound off and on. Add captions or other accessible context through the controls currently available to the account. Do not assume a speech-to-text transcript is accurate; verify names, figures, and technical terms. Keep a version record if the video is part of a campaign. - Make the text match the actual video. - Check captions, sound, and timestamp accuracy. - Preview the final export before upload. ## Upload from the web or mobile app **Answer:** X documents web upload through the post composer and mobile recording or importing through its app; use the path that matches your device. For web, X Help describes using the compose box or post button, selecting the gallery control, choosing a supported video file, completing the message, and posting. In the app, the documented options include recording or selecting a video from the device. Menu labels vary by platform and version, so follow current help if your composer differs. Wait for the file preview to appear and confirm that the intended video is attached. If X reports that the format is unsupported, consult the current requirements and export a compatible copy from your editor. Avoid submitting the same post several times while upload status is uncertain. - Use current device-specific instructions. - Check the attached preview before submitting. - Do not retry until you know whether a post was created. ## Review download and privacy settings **Answer:** Before posting, review whether the video can be downloaded and whether the post audience matches your intent. X's current Help article describes a video download control in the composition flow for eligible experiences and notes that the download choice may not be changeable after posting. The available option can depend on account age and app version. Check the setting before publication if downstream downloading matters to you. Do not assume deleting a video can fully reverse copies already saved by others. Confirm post visibility and account privacy. A public video and a protected-account post have different audiences. If the clip includes a customer, employee, or event participant, make sure permission and disclosure cover the way it will be shared. - Review the current video download option before publishing. - Confirm account privacy and post audience. - Get consent and rights for people shown. ## Publish and inspect the post **Answer:** Submit once, wait for confirmation, then open the actual X post to verify the video and text. After posting, inspect the public or intended-audience view. Check the video playback, crop, sound, post text, timestamps, and account attribution. If the upload is absent or wrong, record what happened and check for a duplicate before retrying. A composer preview is not proof that the final post is available to viewers. For time-sensitive material, assign someone to verify the post quickly and respond to questions. If there is a link, open it from the viewer's path where possible. Keep the X post URL as evidence of publication, but do not claim reach, views, or conversions without observing those measures. - Save the X post URL and verification time. - Check playback and audience visibility after publication. - Separate published status from performance results. ## Handle errors and keep ownership clear **Answer:** If the video fails or appears incorrectly, check X's current support guidance, the account, and the published post before editing or resubmitting. An unsupported file, slow upload, account restriction, privacy setting, or temporary service issue can affect posting. Check the current error message and X Help. If a post exists but the video failed, use the current edit or deletion controls only after confirming the exact post and understanding whether the text or media can be changed. A team record should identify the file owner, rights approval, final post text, account, reviewer, upload date, and public URL. Do not store passwords or tokens in the record. If another person manages the account, use the authorized workflow rather than sharing credentials. - Use current support guidance for errors. - Check for an existing post before resubmitting. - Use authorized account access and a minimal audit trail. ## Do not imply an untested scheduler **Answer:** This guide describes X's own post composer and does not establish an automatic FluxGravity publishing workflow. FluxGravity may help prepare a video caption from approved facts, but a text draft is not an uploaded file or posted video. Confirm current product features, permissions, supported media, and plan limits before describing a connected workflow. Free FluxGravity access excludes publishing. No X account was accessed and no video was uploaded for this guide. The illustration is editorial, not a product screenshot. A release version should include a first-hand account test if it gives detailed current UI steps, plus an editorial check of X's upload requirements. - Treat drafted copy as unposted until verified. - Recheck X's current upload documentation at release. - No X or FluxGravity post result is claimed. ## Frequently asked questions ### How do I post a video on X?
