What is frame interpolation?

This workflow contains custom nodes. You need to install them using ComfyUI Manager before running the workflow.
Frame interpolation generates intermediate frames between existing frames, resulting in smoother motion and improved temporal consistency. This technique is essential for video post-processing and can significantly improve the quality of generated videos.

Use cases

Frame interpolation supports:
  • Increasing frame rate in short clips - Convert low-FPS videos to higher frame rates
  • Smoothing motion in generated or edited video - Reduce stuttering and stepping artifacts
  • Preparing sequences for downstream video models - Standardize frame rate for consistent processing
  • Fixing low-FPS generations - Many video generation workflows default to 16fps, which can introduce noticeable stutter

Why frame interpolation matters

Many image and video generation workflows still default to 16fps, which can introduce noticeable stutter, stepping, and uneven motion, especially in camera moves and character animation. Frame interpolation is an effective way to smooth these artifacts without regenerating the source frames, making motion feel more natural while preserving the original composition and timing. Rather than always treating interpolation as a final post-process, it can also be used as a preprocessing step, allowing you to standardize frame rate early and feed cleaner temporal data into larger animation and video pipelines.

Frame interpolation workflow

The Frame Interpolation workflow is available in the ComfyUI template library. It inserts new frames between existing ones with a FILM or RIFE model, so you can raise the frame rate of a clip without regenerating it. Frame Interpolation workflow preview

Open in Comfy Cloud

Download Workflow

Download JSON or search “Frame Interpolation: FILM or RIFE” in Template Library
The workflow loads an interpolation model from ComfyUI/models/frame_interpolation/. Download film_net_fp16.safetensors into that folder, or pick a RIFE variant from the Comfy-Org/frame_interpolation repository.

Get started

  1. Update ComfyUI to the latest version and install the required custom nodes with ComfyUI Manager.
  2. Download the FILM model into ComfyUI/models/frame_interpolation/.
  3. Open the Template Library and search for Frame Interpolation.
