Social Media Format
Fit a video or image to the frame size of Instagram, TikTok, YouTube Shorts, X, Facebook or LinkedIn, and keep the post caption within the platform's limit.
The Social Media Format node prepares a video or an image for one social media platform. You choose the platform and the format, such as an Instagram Reel or a YouTube Short, and the node resizes the media to that exact frame. The node also holds the post caption, with a counter for the platform's character limit and a live preview of the post.
When to use it
- You publish the same video to several platforms and each needs its own frame size.
- You want to see how a post will look on the platform before you publish it.
- You want the caption checked against the platform's limit before a publishing node posts it.
Quick start

Press Tab on the canvas and choose Video › Format & Export › Social Media Format.

Tips
- Choose the platform first. The size, duration and text limit in the panel update as soon as you change Platform or Content Type.
- Crop for a full frame. Pad keeps the whole picture but adds bars. Crop fills the frame and usually looks cleaner on a phone.
- Check the length. Keep a video within the Max Duration the panel shows. Use Trim Video to shorten it.
- Only need a new shape? Resize Video changes the aspect ratio without the platform presets and the caption.
- Publish automatically. Connect the outputs to TikTok Post, YouTube Upload or another publishing node. See Publishing to social media.
Frequently asked questions
Which frame size does Social Media Format use for Reels, TikTok and Shorts?
Instagram Story / Reel, TikTok Video, YouTube Short and Facebook Reel all use 1080×1920, a vertical 9:16 frame.
What happens when my caption is longer than the platform allows?
The character counter above the Caption / Post Text field turns red, and the panel says how many characters are over the platform's limit. Shorten the text before you publish.
Can Social Media Format prepare images as well as videos?
Yes. The Media input accepts a video or an image, and some formats are image formats, such as X Image Landscape and LinkedIn Image Square.
How many credits does Social Media Format cost?

What is the difference between Social Media Format and Resize Video?
Resize Video only changes the aspect ratio. Social Media Format applies a platform's exact frame size, shows a preview of the post, and carries the post text to the next node.
