HL-OutPaint Extends Video Spatially at High Resolution Over Long Sequences
May 18, 2026
HL-OutPaint uses a two-stage coarse-to-fine pipeline with Global Coarse Guidance — a low-resolution structural representation built from dominant motion — to maintain spatio-temporal consistency during large spatial extrapolation over long video sequences. The approach targets format adaptation use cases like aspect ratio conversion.

HOW THIS AFFECTS YOU
●
builderRelevant if you're building video format conversion pipelines that need to handle long sequences with large spatial extrapolation.
●
researcherThe Global Coarse Guidance mechanism is a concrete approach to global consistency in video outpainting worth comparing against diffusion-based baselines.
●
designerThis enables automated aspect ratio adaptation for long-form video content without manual cropping or reframing.
