[HELP] Indexer doesn't create .ffindex file.

[Refzyy]

My problem is that everytime im trying to use an .mkv file as input file, the indexer won't create an .ffindex file.
It only happens when using an .mkv file, i can use .mp4 and .m4v files but not this one file format. Maybe also other file formats don't work but i mainly need to use .mkv files :/

Im using: Windows 10 64Bit
Error message: Indexer didn't create: C:\Users\Refzyy\AppData\Local\Temp\15_43_37_3210.ffindex!
What i wanted: I wanted to convert an 4k30fps file into an 4k 60fps file using avisynth.

Are you using Avisynth or Vapoursynth?

Avisynth.

Does the Avisynth Preview work properly? My guess is that the avisynth source filter used doesn't support your input file, also try:
Filtering->Avisynth->Misc->LibavVideosource insread of FFmpegSource
or
Filtering->Avisynth->Misc->Use FFms2000

Ps.: For 4k content better use Vapoursynth since it scales better with more threads.
