I have a .MP4 movie exported from Blender in 24fps in good quality, without any pixelation problems. In whatever movie player I open it, there are no pixelation problems.

When I create a new project in Final Cut, also in 24fps, and I import the clip, and I play it in Final Cut as such, even in the Timeline viewer (same problem after exporting from Final Cut), then every 18th or 19th frame gets pixelation problems as such:


How to solve please? Should I prepare the Blender movie in another file format?

For your reference, here is an undistorted frame:

The problem remains if I make a short (1-sec) small-resolution (550x550) sample.

Again, the 19th frame is distorted:

It should look more like this:

Here are my render settings for this small-resolution sample:

    This looks like "datamoshing", which happens when p, b and i-frames do not align properly. Which export settings did you use? Have you tried rendering a smaller portion again to see if the file is corrupted? – Florian Claaßen Feb 6 '20 at 8:19
  • @FlorianClaaßen I have tried using a short small-resolution new render sample from Blender. The same problem occurs within Final Cut (see my updated answer). What can I do please? My render settings have also been included. – O0123 Feb 6 '20 at 18:24

    Ah, I think I've got it. In the Video-settings, your Keyframe-intervals are set to 18 frames. For more information about keyframe intervals, this article was quite helpful to me: community.adobe.com/t5/premiere-pro/… I believe you should be able to resolve the issue by setting the interval to 1, thus placing a keyframe for each frame. – Florian Claaßen Feb 7 '20 at 8:36
  • @FlorianClaaßen And is there no way to prevent this after importing some clip into Final Cut? Because the original video from Blender took 2 days to render. – O0123 Feb 8 '20 at 16:48
