Conform frame rates in Final Cut Pro for iPad
When a clip’s frame rate differs from the timeline’s frame rate, Final Cut Pro uses a frame-sampling method to change the clip’s frame rate to match that of the timeline. You can choose (on a clip-by-clip basis) which frame-sampling method Final Cut Pro uses to modify the clip’s frame rate. The method you choose depends on how important it is to eliminate visual stuttering and artifacts.
Here are things to keep in mind when working with multiple frame rates:
You can't change the frame rate of a timeline after you create it.
Choose video and audio project properties based on how you intend to share your final video with your audience. For example, if you’re editing a project with mixed-format media and you intend to share it as a 1080p HD video, you should set your timeline’s video properties to 1080p HD.
If you have a clip that matches the video and audio properties of the format in which you intend to share your project, add this clip to your timeline first. Final Cut Pro automatically creates matching timeline settings.
Choose a method for conforming the frame rate
In Final Cut Pro for iPad, open a project.
In the timeline, add a clip with frame rate that’s different from the timeline’s frame rate.
Tap the clip in the timeline to select it.
Tap Inspect in the lower-left corner of the screen.
In the inspector, tap
next to Rate Conversion, then tap one of the following:Normal (Floor): The default setting. Final Cut Pro duplicates frames or rounds down to the nearest whole frame to match the clip’s frame rate to the project’s frame rate.
Nearest Frame: Final Cut Pro rounds up or down to the nearest whole frame to match the clip’s frame rate to the project’s frame rate. This setting reduces artifacts but may cause visual stuttering. For the highest-quality playback, rendering is recommended.
Frame Blending: Creates in-between frames by blending individual pixels of neighboring frames. Slow-motion clips created with Frame Blending appear to play back more smoothly than those created with the Normal (Floor) or Nearest Frame setting. This setting provides better reduction of visual stuttering, but you may see some visual artifacts. Rendering is required.
