Video Frame Interpolation

Edited by Segmind Team on October 6, 2025.

What is FILM?

FILM (Frame Interpolation for Large Motion), by Google Research, is a state-of-the-art AI model that is designed to perform frame interpolation for image and video sequences. It can generate professional-level intermediate frames between images that are widely spaced, producing smooth results even with considerable motion between each frame. FILM can effectively perform better than the conventional interpolation techniques to render fluid and life-like motion by making use of a highly advanced scale-agnostic feature pyramid and bi-directional motion estimation.

Key Features of FILM

• •It employs a scale-agnostic feature pyramid for handling both small and large movements
• •It has a bi-directional motion estimator with shared weights across scales
• •It can perform high-quality frame synthesis with temporal consistency
• •It can do intelligent inpainting of occluded regions
• •It supports various output frame rates - up to 120 FPS
• •It can execute flexible frame multiplication (1-10x) for customizable smoothness
• •It includes the optional audio preservation in processed videos

Best Use Cases

• •It can be utilized to create professional slow-motion footage from standard videos
• •It can create smooth time-lapse photography sequences
• •It can improve gaming and sports replay footage
• •It can convert low frame rate content to high frame rate
• •It can improve motion clarity in security camera footage
• •It can generate smooth transitions for animation and VFX

Prompt Tips and Output Quality

For optimal results with FILM:

• •Use short video clips for faster processing and better quality
• •Choose frame multiplier based on desired effect:
  • •2-3x for natural slow motion
  • •4x+ for ultra-smooth, dramatic effects
• •Select appropriate output FPS:
  • •24 FPS for cinematic feel
  • •60 FPS for smooth gaming/ sports content
  • •120 FPS for maximum fluidity
• •Preserving audio when maintaining original timing is important

FAQs

What makes FILM different from other frame interpolation models?

The unique scale-agnostic architecture of Frame Interpolation for Large Motion (FILM) makes it possible to effectively manage much larger motions than commonly available models to deliver sharper and more accurate results even when there are considerably high number of movements between frames.

What is the recommended input video length?

To achieve high-end results, consider going with shorter clips (under 30 seconds) as they produce the best results and process more quickly. On the other hand, longer videos can be processed in segments if needed.

Can FILM handle any type of video content?

FILM is designed to work well with most of the content, but it performs best with clear, well-lit footage. If you need to process assets with fast-moving objects and complex scenes, then use lower frame multiplication settings for optimal results.

How do I choose between different frame multiplier settings?

It is quite simple to toggle between different frame multiplier settings: start with 2-3x for natural-looking results, increase to 4x or higher for more dramatic slow-motion effects; higher multipliers may introduce more artifacts in challenging scenes.

FILM: Frame Interpolation for Large Motion

FILM is an advanced AI model by Google Research designed to generate smooth, high-quality intermediate frames between widely spaced images. It leverages a scale-agnostic feature pyramid and bi-directional motion estimation to handle large movements, inpaint occlusions, and maintain temporal consistency. Use FILM to turn ordinary footage into cinematic slow motion, smooth time-lapse sequences, or crisp gaming and sports replays.

Getting Started

1. •Provide a short input video URL for faster turnaround.
2. •Choose your Frame Multiplier (1–10) for desired smoothness.
3. •Set Output FPS (1–120) to match your target viewing experience.
4. •Toggle Preserve Audio if original sound is needed.
5. •(Advanced) Enable Base64 Output to embed results directly in web pages.

Parameter Recommendations

Examples

Cinematic slow motion (film look):

{
  "input_video": "https://…/clip.mp4",
  "frame_multiplier": 2,
  "output_fps": 24,
  "preserve_audio": true
}

Ultra-smooth gaming replay:

{
  "input_video": "https://…/game.mp4",
  "frame_multiplier": 4,
  "output_fps": 60,
  "preserve_audio": false
}

Best Practices

• •Keep clips under 30 seconds for faster processing. Split longer videos into segments.
• •For scenes with rapid motion or complex backgrounds, use lower multipliers (2–3×) to reduce artifacts.
• •If you need maximum fluidity (e.g., slow-motion showcases), push multipliers to 6–8× but review results for occasional ghosting.
• •Preserve audio when timing and original dialogue or effects are critical; disable it when you plan to re-score or overlay new soundtracks.
• •Use Base64 output sparingly—this is ideal for quick embedding but increases payload size.

Troubleshooting

• •Soft edges or ghosting in fast pans? Lower the multiplier by 1 and reprocess.
• •Inconsistent inpainting on occluded regions? Try a two-pass approach: first interpolate at 2×, then run a higher multiplier on sections of interest.
• •Audio desync? Ensure “preserve_audio” is enabled and match the final FPS to your original timeline.

With these settings and tips, you can harness FILM’s power to produce buttery-smooth, visually stunning footage across a variety of projects.
