1080p vs 4K: which should I use for social media?
For social feeds, the practical answer: shoot in 4K if your phone can, but export and upload 1080p. TikTok, Reels, and most feed viewing happen on phone screens at compressed bitrates where 4K's extra detail largely vanishes — while 4K files upload slower and eat storage. Shooting 4K still pays because it gives you room to punch in 20–30% in the edit with zero quality loss.
Where 4K genuinely matters: YouTube long-form on TVs, footage you'll crop heavily, and client work with 4K delivery specs. EseCut's free plan exports 1080p (the social sweet spot); 4K export is in Pro for when a delivery truly needs it.
