An editor takes a softly rendered Sora, Seedance, or Kling clip and ships a 4K master to YouTube or broadcast — without regenerating the shot. On Martini's canvas, route the locked clip into the video-upscale tool node downstream of the original generator (Seedance 2, Sora 2, or Kling 3), set 2x for safe defaults and 4x only on hero shots. Stack sparingly: one 2x pass beats stacking 2x then 2x. Final pass before NLE export. Pick a model below to walk through the upscale flow paired to your source generator.
ByteDance
Seedance 2.0 is the upstream model for clips that benefit most from 4K upscaling — its native output is 1080p in a clean, modern look that holds up to resolution enhancement without revealing artifacts. The pipeline is two-stage: generate the source clip with Seedance 2.0, then route the output through a video upscaler tool node (FAL Topaz Video, FAL Video Upscaler, or your workspace's configured upscaler) for the 4K master. The companion `tools/video-upscale` page covers the upscaler's parameters in detail; this how-to focuses on the Seedance-to-4K pipeline specifically. Default 2x upscale (1080p → 4K equivalent at 3840×2160) is the safe choice for most deliverables; 4x is reserved for hero shots where the longer render and higher credit cost are justified by the use case.
Kling
Kling 3.0 is the upstream pick when the source clip features human performers — its human motion engine produces the most anatomically accurate body, face, and clothing motion of any video generator on Martini, which means the upscaler has clean motion to work with rather than soft AI-motion artifacts. The pipeline is identical to Seedance: generate the source on Kling 3.0, then route through the configured video upscaler tool node for the 4K master. Default 2x is the safe choice (1080p → 4K equivalent); 4x for hero shots only. The companion `tools/video-upscale` page covers upscaler parameters; this how-to focuses on the Kling-paired pipeline specifically.
