The short answer
The failed version of this workflow looks like: finish a video, export it for Instagram, re-crop for TikTok, re-export for YouTube, then write four captions from scratch. That is four exports and forty minutes, and it is why most people quietly stop repurposing after a fortnight.
Rule 1: one export, decided up front
Shoot and export 9:16 vertical. It is native on Reels, TikTok, Shorts, Stories and Threads, and accepted on X, LinkedIn and Pinterest. One file clears almost every destination, and the exceptions are predictable rather than surprising.
Keep it under 3 minutes if YouTube Shorts is in your list, because Shorts is the tightest cap of the major formats and it governs the whole set. Full per-platform limits are in the video specs table.
Rule 2: adapt the text, not the video
The part that actually needs to differ per platform is the words, and it is much cheaper to change than the footage.
- TikTok — the hook belongs in the first line, and the text is searchable, so say what the video is.
- Instagram — tolerates a longer caption; the first sentence is what shows before "more".
- YouTube Shorts — the title carries most of the weight, more than the description.
- LinkedIn — context first. The same clip needs a sentence explaining why a professional audience should care.
- X — shortest of all. One line, and the video does the rest.
This is roughly a minute of work per destination and it is the entire difference between repurposing and spamming. Platforms do not compare notes with each other, but humans notice a caption written for somewhere else.
Rule 3: schedule in one pass, not as you go
Upload once, write the variants in one sitting, queue them all, then close the tab. Publishing to one platform now and the others "later today" is how the later ones never happen.
It also makes your numbers readable: same video, same publish time, so any difference in performance is the platform rather than the hour you happened to be free.
What not to repurpose
- Anything with a visible watermark from another app. This is not a style point — on Instagram a watermarked Reel is ineligible for the recommendation surfaces that reach non-followers. See recycled content.
- Platform-specific references. "Link in bio" means nothing on YouTube.
- Long-form as-is. A 20-minute video is not a Reel with a trim; it needs a genuinely chosen segment.
Questions people actually ask
How do I repurpose one video for social media?
Export a single 9:16 vertical file under 3 minutes, then adapt only the caption and title per platform. Re-editing the video per destination is what makes repurposing expensive; changing the text is what makes it work.
Does reposting the same video hurt reach?
Not by itself. Each platform judges the post in front of it. What does hurt is an identical caption written for a different platform, or a visible watermark from another app.
How many platforms should I post to?
Start with the two or three you can consistently feed, then expand. Our free plan covers 5 channels with unlimited scheduled posts, which is past the point most people can keep supplied with content.
