MikuMikuDance (MMD) can only load AVI videos container instead MP4. There were no AVI codec spec that the application support, BUT its depend on what decoder installed on your System/Windows.
To support to decode H264, install x264vfw (video for windows). After some experiment with FFMpeg the decoder seems works well with baseline profile instead main or high.
> ffmpeg -i "INPUT.mp4" -c:v libx264 -profile:v baseline <VIDEO_OPTS> <AUDIO_OPTS> "OUTPUT.avi"The VIDEO_OPTS and AUDIO_OPTS are optional or may be omitted.
For VIDEO_OPTS values:
- 30 fps video:
-filter:v fps=30 - enable opencl:
-x264opts opencl
For AUDIO_OPTS values:
- No audio or mute:
-an - MP3 audio:
-c:a libmp3lame

To cut the video refer to “-ss” and “-t” options, see: https://trac.ffmpeg.org/wiki/Seeking
If you have nVidia GPU cards, change -c:v libx264 into -c:v h264_nvenc to enable using GPU encoder.
