Good day,
If I set num-frame with the desired target frame rate value (ex: 60fps), the output_frames folder will contain only 60 frames when I run these two lines:
$targetFps = 60 rife-ncnn-vulkan -i input_frames -o output_frames -g 0,1 -m rife-v4.16-lite -n $targetFps
Hence, I ffprobe'd the input file for the total frame count, then set num-frame by multiplying its value by (60 / 24) = 2.5, no luck.
Is it possible to use the num-frame parameter in order to interpolate from 24 to 60fps directly? If so, can you give a usage example?
Thank you kindly.
