Myth: 1080p export is fine, 4K is pointless on a phone-watched Short
Sounds logical. Tested it: YouTube re-compresses everything, and exporting at higher resolution survives that compression better. A 4K-downscaled-to-1080 export looks sharper than a native 1080 export after YouTube's encoder mauls it.
— CapCut: exports up to 4K free
— InShot: 4K locked behind Pro
— Premiere: full control, heavy
Pros: cleaner edges, less blocky motion in fast cuts.
Cons: bigger files, slower upload, marginal on static talking-heads.
Price: CapCut free does 4K; InShot Pro $3.99/mo.
Best for: motion-heavy content (sports, gaming, fast b-roll).
Verdict: export above 1080 if your tool allows. Static face cam? 1080 is genuinely fine. Skip the upgrade there.
