Nero AI frame interpolation is a technique that uses artificial intelligence to create additional frames between existing frames in a video. This process enhances the smoothness of motion by filling in the gaps between frames, making the video appear more fluid and visually appealing.
AI frame interpolation will be enabled automatically if you select a frame rate higher than the original.
The scene detection switch is used to avoid strange frames generated by interpolation when the scene changes. If there is no scene change in your video, you can turn off this option to speed up the frame generation.
AI slow motion
AI slow motion can only be enabled when the AI frame interpolation is enabled.
Select the time scale factor from 2x to 8x and choose the audio post-processing method to start processing.
Audio post-processing method:
Keep original audio: do not process the audio and keep the original length, please note that the audio will lose synchronization with the video.
Remove audio: remove audio track, suitable for the users who want to process audio separately.
Sync audio (preserve pitch): slow down the audio pace and keep the audio pitch, please note that the audio may sounds strange when the speed is low.
Sync audio (do not preserve pitch): slow down the audio pace and the audio pitch become lower than the original.

Please check the following preview screenshots and recommendations are on the below.
All the original videos resolution are 1280×720. Upscale to 3840×2160 (4K) and zoom to 200% to preview.
2D animation
Animation model is strongly recommended to increase the sharpness and contrast to get the clear view of the upscaled video.
Animals
Versatile model is recommended to keep the details of the animals. If you feel the processing time is too long, Fast model can also be used but it keeps more noises than the versatile model.
Portraits
Realistic model is recommended to refine the skin texture and suppress the noises. If you prefer to keep the skin texture, versatile model is also recommended.
Still life
Realistic model is recommended to refine the edges by sharpening the video and suppress the noises. If you prefer the less sharpness view, versatile model is also recommended.
Landscape & architecture
Versatile model is strongly recommended to keep the sharpness and slightly increase the contrast to reserve more details from the original video.
3D CG
Realistic and versatile models are both recommended to retain the sharpness and reduce the blurry. If the original video has been applied some post-processing effects like film grain, you can use the versatile model to keep these effects. If it is not, realistic model can process the video more faster.
