Do you edit differently for TikTok, Reels, and Shorts?

Compares what creators change when cross-posting one short video across major feeds.

I am skeptical of posting the exact same file everywhere without checking the surface. Text placement, title dependency, music expectations, and the ending prompt can all feel different across TikTok, Reels, and Shorts. I still think the same core idea can travel well. What do you change before cross-posting: first frame, captions, sound, ending, or nothing until the data says so?
