Post YouTube Shorts to Threads automatically

A Short fits on Threads without any trimming, since Shorts top out at 3 minutes and Threads takes 5. deploy.social posts the original file to YouTube Shorts and Threads together, or schedules it, with a 500-character caption for Threads.

The first step in Deploy: a Connect button for each of YouTube, Instagram, TikTok, Facebook, Threads, X and Bluesky.
Step one. Connect YouTube and Threads once, then pick where each video goes.

What changes between the two

Deploy checks all of this before it posts, so you don't have to.

A video uploaded to Threads plays in the feed. A pasted YouTube link shows as a link card.

Threads also lets you add a first comment to a video, which is a good home for the link back to your channel.

Post it to both at once

  1. Keep the original

    Use the finished video from your editor, the same file you uploaded to YouTube. That keeps the quality of the original rather than a download of it.

  2. Connect YouTube and Threads

    Open Deploy and connect both. It takes about a minute each, and you only do it once.

  3. Upload once

    A vertical 1080 by 1920 MP4 plays well on both.

  4. Write the caption

    Add a title and a description for YouTube. The Threads box holds 500 characters, so cut the description down there. Deploy offers Shorten, which starts a version just for Threads.

  5. Deploy

    Both go out together, or schedule them for later. Each platform reports back on its own.
