# Threads
> Connect Threads, publish posts and chains, and understand text, carousel, image, video, GIF, Ghost Mode, and topic-tag limits.
Use Threads in Omni Writes for single posts, scheduled posts, multi-post chains, Ghost Mode, mixed-media carousels, GIPHY GIFs, and topic tags.
This page covers Threads behavior and the media accepted by Omni Writes—not plan or billing limits. Ghost Mode exists only on Threads; Instagram, Facebook, LinkedIn, and X do not have Ghost Mode in Omni Writes.
## Availability at a glance
| Capability | Available | Notes |
| --------------------- | --------- | -------------------------------------------------------------- |
| Text post | Yes | Publish now or schedule |
| Multi-post chain | Yes | Up to 11 posts; published as replies in order |
| Ghost Mode | Yes | Threads-only; text-only; archives after 24 hours |
| Single image or video | Yes | Threads fetches and processes the file |
| Mixed-media carousel | Yes | 2–20 images and/or videos |
| GIPHY GIF | Yes | One attachment on a text post |
| Uploaded GIF file | No | Use the GIPHY picker |
| Topic tag | Yes | Applied to the root post (not with Ghost Mode) |

| Calendar and Replies | Yes | Replies depends on connection permissions |
| Polls and DMs | No | Not in the current integration |
## Connect Threads
Go to **Settings → Channels**.
Choose **Threads**, complete Meta/Threads OAuth, and approve publishing permissions.
Verify the connected Threads username appears on the channel card.
## Publish a post or chain
Select Threads, write up to 500 characters per post, add media or a GIPHY attachment, and optionally add one topic tag to the root post. For a chain, attach media to the exact post where it should appear. Chains support up to **11** posts. Auto-split can break a long draft into multiple posts while staying inside that 11-post ceiling.
## Ghost Mode
Ghost Mode publishes an ephemeral **text-only** Threads post that stays active for **24 hours**, then archives automatically. It is a **Threads-only** product feature.
| Rule | Behavior in Omni Writes |
| ----------------- | -------------------------------------------------------------------------------------------- |
| Platforms | Ghost Mode appears only for Threads—not Instagram, Facebook, LinkedIn, or X |
| Selected networks | In the main composer, Ghost Mode stays on only when **Threads is the only selected network** |
| Media | Not allowed — images, video, carousel, GIF, and link attachments are stripped |
| Topic tag | Cleared while Ghost Mode is on |
| Chains | Single text post only; turn Ghost Mode off before adding another post |
| Replies as ghost | You cannot reply to another post with a ghost post |
Use the Ghost Mode control in the Threads composer when you want a short-lived text post.
## Text and publishing limits
| Rule | Threads platform | Current Omni Writes |
| --------------- | -----------------------: | ---------------------------------------------------: |
| Text | 500 characters | 500 characters |
| Topic tag | One | 1–50 characters; periods and ampersands are rejected |
| Chain length | Platform reply chain | Up to 11 posts in the composer |
| Published posts | 250 per rolling 24 hours | The platform quota still applies |
| Carousel | 2–20 items | 2–20 items |
## Media limits
| Media | Threads platform | Current Omni Writes |
| -------------------------- | ------------------------------ | ----------------------------------- |
| Images | 1, or 2–20 in a carousel | Up to 20 |
| Image size | 8 MB each | 8 MB each |
| Image formats | JPEG, PNG | JPG, JPEG, PNG |
| Videos | 1, or multiple carousel videos | Up to 20 carousel items |
| Video size | 1 GB each | 250 MB each (product) |
| Video duration | 5 minutes | 5 minutes |
| Mixed image/video carousel | Allowed | Allowed |
| GIF | GIPHY attachment | One GIPHY attachment on a text post |
Threads allows a 1 GB video, but Omni Writes currently accepts up to 250 MB. The lower limit applies here.
### Image details
* Width: 320–1440 pixels.
* Maximum aspect envelope: 10:1.
* Use sRGB color.
* A carousel can mix images and videos.
### Video details
* Container: MP4 or MOV.
* Codec: H.264 or HEVC with AAC audio.
* Duration: more than 0 and no more than 300 seconds.
* Width: up to 1920 pixels.
* Frame rate: 23–60 FPS.
* Aspect ratio: 0.01:1 through 10:1.
* 9:16 is recommended for vertical content.
## GIFs and topic tags
A Threads GIF in Omni Writes uses GIPHY; it is not an uploaded GIF file. Use one GIF on a text post and do not combine it with uploaded media. One topic tag can be sent with the root post; ordinary hashtags remain part of the text. Ghost Mode disables topic tags and GIF attachments.
## Media processing
Threads creates media containers before publishing. Every carousel child must become ready before the parent carousel publishes.
Keep scheduled assets available until publishing completes. A deleted, private, or expired file can make the complete carousel fail.
## Common problems
* **Media fetch failed:** Re-upload the file and retry.
* **Too many carousel items:** Reduce the set to 20 or fewer.
* **Video too large:** Compress it below 250 MB.
* **Ghost Mode blocked media:** Turn off Ghost Mode before attaching media or building a chain.
* **Ghost Mode turned off automatically:** Deselect other networks so Threads is the only destination, or keep Ghost Mode off for multi-network posts.
* **Authorization expired:** Reconnect Threads, confirm the username, and retry from Calendar.
