Sora Video Upscaler Free

Sora outputs at 480p for free users and up to 1080p for paid tiers, depending on the selected aspect ratio and subscription plan. Sora 2 offers higher resolutions in paid plans. This upscaler works on any Sora output resolution.

Yes. If your Sora video is 1920×1080 (1080p), 2x upscaling produces a 3840×2160 (4K) output. For 720p inputs, upscaling produces 1440p. The maximum upscaled output is approximately 10 megapixels due to browser memory limits.

Yes. Add the Sora watermark preset mask from the presets dropdown and enable the upscale checkbox. Both operations run in the same pass — you get a clean, watermark-free, 4K Sora video in one step.

For maximum quality, start from the highest resolution Sora output available.

Yes. Sora 2 uses the same video container format as Sora. Upload any Sora 2 video and upscale it the same way. Sora 2 watermark presets are also available for combined removal + upscaling.
