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.

Video to Video mode

In this mode the model edits, extends, or restyles an uploaded source video. Below are the parameters that ByteDance Video Upscaler supports in this specific mode.

ByteDance Video Upscaler parameters in Video to Video mode

  • video — required
  • processing_type — options: standard; default: standard
  • scene — options: aigc, short_series, ugc, old_film, common; default: aigc
  • target_resolution — options: 720p, 1080p, 2k, 4k; default: 4k
  • target_fps — options: 24, 30, 60, 120; default: 60

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.
