The most expensive mistake in social media editing isn't bad cuts — it's wrong pacing for the platform.

The most expensive mistake in social media editing isn't bad cuts — it's wrong pacing for the platform.

TikTok, YouTube Shorts, and Instagram Reels all have different average attention curves. Shorts viewers drop off hardest in seconds 3-7. TikTok viewers often give 10-12 seconds before the first major drop. Reels viewers are somewhere in between, with a second drop around 50-60% completion.

If you're cutting video the same way for all three platforms, you're leaving completion rate on the table. The edit that works on TikTok is usually too fast for YouTube Shorts, where retention data shows slightly more tolerance for setup. The edit that works on Reels often moves too slowly for TikTok's native audience.

Practical adjustment: export the same content with different cut timing per platform. On TikTok, keep your fastest cuts and tightest transitions for the first 8 seconds. On Shorts, you can breathe slightly more. On Reels, focus on the midpoint drop — most Reels lose viewers at exactly 50% completion, so your biggest payoff or most interesting information should land just before that.

One edit file, three platform exports, meaningfully different completion rates.
