Post Instagram Reels to X (Twitter)
Upload your original video to X and it plays in the feed, up to 20 minutes. deploy.social posts it to Instagram Reels and X together from one upload, with a caption cut to X's 280 characters. X is on every plan.
What changes between the two
| Instagram Reels | X | |
|---|---|---|
| Length | 3 seconds to 15 minutes | Up to 20 minutes, longer on Premium accounts |
| Caption | 2,200 characters | 280 characters |
| Shape | Vertical is best, wide and square are accepted | Anything from 1:3 to 3:1 |
| Account | Business or Creator | Any account |
A video, not a link
A video uploaded to X plays in the feed. A pasted link to your Reel shows as a link card that people click through to Instagram to watch.
Reels are vertical, and X takes anything from 1:3 to 3:1, so the same file works on both. Instagram only lets tools post to Business and Creator accounts.
Post it to both at once
Keep the original
Use the finished video from your editor or camera roll, the same file you'd upload to Instagram. Posting from the original keeps every platform on the best quality you have.
Connect Instagram and X
Open Deploy and connect both. It takes about a minute each, and you only do it once.
Upload once
A vertical 1080 by 1920 MP4 plays well on both.
Write the caption
Write one caption. The X box holds 280 characters, so if yours is longer, Deploy says so and offers Shorten, which starts a version just for X. The other platforms keep the full one.
Deploy
Both go out together, or schedule them for later. Each platform reports back on its own.
