Quick answer
Most AI video models natively generate between 720p and 1080p, with some supporting higher outputs on premium settings. To go beyond that, creators run an AI upscaling pass, which can bring footage to sharp HD or 4K by reconstructing detail. So while raw generations rarely start at 4K, a generate-then-upscale workflow gets there reliably for delivery on large screens.
Resolution is a compute trade-off: doubling the pixel dimensions roughly quadruples the work per frame, so models default to resolutions that balance quality with generation speed and cost.
For most destinations — TikTok, Reels, web embeds — native 1080p-class output is already sufficient. Upscaling matters for YouTube at high quality settings, TV display, and client deliverables.
VdoBloom pairs its generation models with a Topaz-powered video upscaler, so a generated clip can be enhanced toward HD or 4K inside the same platform.
