# Threads Formats, media and text limits, options, inbox and analytics on Threads. Publish `feed` and `carousel` to Threads, read every post's numbers, and answer comments once Meta approves Rizamo's access. Set a target's `format`, or leave it out and Rizamo picks one from the files. ## Formats [#formats] | Format | Files | Text | | --- | --- | --- | | `feed` | Text alone, or 1 image or video | 500 | | `carousel` | 2 to 20 images or videos | 500 | ## Media [#media] Rizamo takes JPEG, PNG, WebP, MP4 and MOV files up to 4 GB. What Threads takes: - **Images:** JPEG or PNG, up to 8 MB, up to 1,440 px wide, 1:10 to 10:1 on `feed` and `carousel`. - **Video:** H.264 or HEVC with AAC audio, 23 to 60 frames a second, up to 1,920 px wide. | Format | Length | Size | | --- | --- | --- | | `feed` | 1 s to 5 min | up to 1 GB | | `carousel` | 1 s to 5 min | up to 1 GB | ## What Rizamo does to files [#what-rizamo-does-to-files] - **Images:** another type becomes JPEG or PNG; a larger file is compressed under 8 MB; a wider one is made 1,440 px wide; `feed` and `carousel` images outside 1:10 to 10:1 are fitted to it over a blurred copy of themselves. - **Video:** one Threads does not take as it is (its codec, frame rate, width or size) is converted to H.264 and AAC within those limits; one whose header is not at the front only has it moved there, for streaming. Its length cannot change: a video too short or too long for the format is refused when it is attached. - Your file itself never changes: the copy is made when the post goes out, and each target's `changes` says what was done. ## Text [#text] - Up to 500, counted in characters, each emoji as its bytes in UTF-8 (a 😀 counts 4). Rizamo counts the same way, so `POST /v1/posts/validate` refuses what Threads would. - A first comment takes up to 500 characters. - Up to 5 different links in a post, a link card included. ## Options [#options] Under `options.threads` on a target. Each says which formats take it. | Option | Type | What it does | | --- | --- | --- | | `linkAttachment` | string | Text posts (no image or video) without a poll: a link shown as a preview card. Left out, Threads makes the card from the first link in the text. A post takes at most 5 different links, this one included. | | `poll` | object | Text posts (no image or video) without a link card: a poll. Threads decides when it ends. | | `topicTag` | string | The post's topic, 1 to 50 characters, without periods (.) or ampersands (&). One per post. | | `replyControl` | `everyone`, `accounts_you_follow`, `mentioned_only`, `parent_post_author_only`, `followers_only` | Who may reply: everyone (Threads' default), accounts_you_follow, mentioned_only, parent_post_author_only or followers_only. On a chain, every post of it. | | `quotePostId` | string | Quote another Threads post, by its id on Threads (a network post's `networkPostId`). | | `isAiGenerated` | boolean | Labels the post as made with AI (Threads' "AI info"): text, image, video and carousel posts, and every post of its chain. | ## First comment [#first-comment] `firstComment` goes out right after the post, as the post's first reply, a post of the profile's own, up to 500 characters. Not with a chain: its next part is the first reply. One it would not take is refused when the post is made (`400`), with the reason. If it fails once the post is live, the post stays published. ## Chains [#chains] `chain` publishes up to 24 more posts after the first, each a reply to the one before, each with its own text and files. A part that fails stops the rest; the parts before it stay live, and publishing the post again goes on from the part that failed. `chainResults` says how each part went. ## After publishing [#after-publishing] - **Edits:** Threads does not change a live post's text: an update to a live post is `not_supported`. - **Deleting:** deleting a post takes it off Threads when the account's `capabilities` include `delete_posts`. Each target's `removal` says what happened. It needs `threads_delete`, which Threads gives only to its testers until Meta reviews Rizamo's access. ## Inbox [#inbox] Replies to the profile's posts are its comments. A profile cannot read or answer replies through Rizamo yet: Threads gives them only to its testers until Meta approves Rizamo's access to replies. A Threads tester who did not allow replies when logging in can log in again and allow them. - Replies to comments: up to 500 characters. They go out in the background: a reply is `sending`, then `sent` or `failed`. - Messages: none. Threads has no messaging API. - Mentions are not read yet. | Action | People's comments | The account's own | | --- | --- | --- | | Hide | yes | no | | Delete | no | yes | | Like | no | no | ## Comment automations [#comment-automations] Comment automations work on Instagram accounts and Facebook Pages only. ## Daily caps [#daily-caps] Up to 250 posts an account in 24 hours, counting posts published. A post over a cap waits for room ([Limits](/limits#publishing)). ## Analytics [#analytics] Days run on Pacific time (`America/Los_Angeles`). On connecting, Rizamo reads back the posts of the last 12 months (up to 500) and 365 days of the account's numbers.
