I have a looping blender animation in mp4 format that is 10,000 frames long, but I basically want to make it longer to the point where the changes between frames are imperceptible, but the animation still progresses over time. I've tried just stretching the clip in kdenlive, but it looks like it does no frame interpolation with default settings, and the transitions between animation positions is perceptible and instantaneous.
I've seen examples of ffmpeg minterpolate used to convert to higher frame rates, and ffmpeg examples to slow down videos (and increase video duration), but is it possible to do both at once with minterpolate?
I'm hoping to get the length to 10 hours, but details about the end frame rate, codecs, etc isn't too important as long as the video
- is able to be uploaded to youtube (https://support.google.com/youtube/answer/1722171)
- takes <24 hours to render
- doesn't have perceptible changes in the animation
