Why does my Canva 4K export look blurry after I upload 4K video?

Yeah, that’s likely the limitation, not a bad export setting. Canva says it can export in 4K, but it downscales uploaded 4K video to 1080p and keeps that 1080p version. So exporting the design at 4K can make a bigger file, but it can’t put back detail that was reduced when the clip was uploaded. If the 4K master matters, do the final cut and export in an editor that preserves the original footage, or use the original file for the last export instead of relying on Canva to carry it through at full resolution.
