How they differ
| X | ||
|---|---|---|
| Posts | video, photos, text | video, photos, text, PDFs |
| Shapes | 16:9, 1:1 | 1:1, 16:9 |
| Text | 280 characters, then a thread | 3,000 characters |
| Title | None | None |
| Options | Long text becomes a thread | Hook-first captions |
A 16:9 video works on both without cropping. The text limit differs (280 against 3,000), so write a shorter version for X in the same post.
02
In the dashboard
- Connect X and LinkedIn to the same profile.
- Pick both in the composer, add the video and the caption, and change the text for either one if it needs its own.
- Post now, schedule, queue or repeat it. Each network’s result shows on its own, with one-click retry if one fails.
