Tella posts your video straight to your X account from Share → Publish. The description becomes the post text, or the title if the description is empty. X posts are public.
Publish a video to X
- Click Share and open the Publish tab.
- Under Destinations, pick X (connect it first if it says Connect).
- Under Post details, click All destinations to show the platform tabs, then open the X tab and write the post in Description.
- Click Publish to X.
Tag an account in an X post
On the X tab, type @ and the start of an account’s name in the Description, then pick the account from the list.
How long can an X post be?
The character count under the description uses your account’s limit: 280 characters, or 25,000 with X Premium or a verified checkmark.
How long can an X video be?
X sets the limit per account: 20 minutes for most accounts, and longer with X Premium or a verified checkmark. Tella reads your account’s limit and greys out X with Unavailable: longer than 20 mins if the video is longer.
Share a Tella link on X instead
Copy your video’s Tella link and paste it into a post. X shows a preview that most viewers can play inline, and some clients open the video on Tella instead.
Upload the video to X yourself
Click Download in the editor and save the video as an MP4, then attach it to a post on X. Set Subtitles to Burned in before downloading if you want subtitles, since X doesn’t take a separate subtitle file. Last modified on September 30, 2026
