AI Video Upscaler | ByteDance 4K Enhancement

Improve an existing clip with ByteDance Video Upscaler. Upload a video and choose target resolution, scene preset, and FPS in AISVIT.

About this model

ByteDance Video Upscaler enhances an existing video instead of generating a new scene from text. Use it after you already have a clip and need cleaner detail, higher target resolution, or frame-rate interpolation.

Best fit tasks

  • Upscaling AI-generated clips from 720p or 1080p toward 2K or 4K delivery.
  • Improving short social, product, storyboard, or demo footage when the composition is already approved.
  • Testing high-FPS output for smoother motion when the source clip is short enough to keep cost predictable.

Main advantages

  • Works from a source video, so it fits a finishing workflow after generation.
  • Supports target resolution choices from 720p to 4K in AISVIT.
  • Can apply frame interpolation when target FPS is higher than the source.

Limitations to know

  • This is an upscaler, not a prompt-first video generator. It requires an existing video.
  • AISVIT exposes the standard processing tier at launch; pro processing is not enabled in the public workflow.
  • Cost depends strongly on target resolution and FPS, so 4K at 60 or 120 FPS can become expensive on longer clips.

Simple workflow

  1. Upload the final or near-final source video you want to improve.
  2. Choose the scene preset that best matches the footage: AIGC, UGC, short series, old film, or common.
  3. Select target resolution. Use 720p or 1080p for tests, then 2K or 4K for a final candidate.
  4. Choose target FPS. 24 or 30 FPS is cheaper; 60 or 120 FPS uses the higher FPS band.
  5. Run a short clip first before processing a longer version.

Input formats

  • Source video file such as MP4, MOV, or WEBM within AISVIT upload limits.

Output

  • Enhanced MP4 video URL at the selected target resolution and FPS.
