Content Framerate

Content should always be delivered in the specified project framerate. While we can accept framerates other than the project framerate, we can only use frame blending and frame sampling, neither option is fantastic.

This often comes up on projects with a 30fps project framerate, that is mixed with 24fps content. The best case scenario is to deliver material that is native to the project framerate. If that is not possible, you may have better luck with Optical Flow or AI tools such as those from Topaz Labs.

Frame Sampling

This interpolation method duplicates or removes frames as needed to speed or slow your footage.

When converting 24FPS to 30FPS content this presents itself as a repeating pattern of four frames of motion and one duplicated frame.

Frame Blending

This interpolation method duplicates or removes frames as needed to speed or slow your footage and blends between the frames to make it look smoother..

As you can see in the image carousel below, this can lead to ghosting or doubling of imagery in interpolated frames.

Optical Flow

This interpolation method duplicates or removes frames as needed to speed or slow your footage and interpolates new frames in between to achieve smoothest possible motion.

With some type of content the algorithim behind optical flow may not yield the best results. Try it on your content and see if it works for you.
