Twitter Video Tools
A focused set of utilities for video-led content on X: prepare video links for your workflow, check your clips against X's format specs, and follow a pre-publish checklist that improves watch time.
- →Hook in the first 2 seconds — assume muted autoplay
- →Captions on: most timeline video is watched without sound
- →Upload natively — external video links get a fraction of the reach
- →First frame readable as a thumbnail
- →One idea per clip; save the rest for the thread
Use the link preparation tools to collect and clean video references from X.
Check your clip against X's specs — duration, resolution, file size, and aspect ratio.
Run the pre-publish checklist: hook in the first 2 seconds, captions on, native upload.
Frequently asked questions
What are X's video specs?
MP4 or MOV, up to 512MB, up to 2:20 for standard accounts (longer with Premium). Recommended: 1280x720 or 1920x1080, 30–60fps. Landscape and square both work; vertical fills more screen on mobile.
Does native video perform better than YouTube links on X?
Dramatically. Native uploads autoplay in the timeline and are favored by the algorithm; external links produce a small card and typically reach far fewer people.
Should I add captions to X videos?
Always — most timeline video is watched muted. Burned-in or uploaded captions significantly lift completion rate, which drives distribution.
