Got the file, if you had compressed the file you could have attached it, but never mind.
From the looks of it the encoding around frame 2039 of 5710.
Try these options (one at a time):

• enabling Filtering->Avisynth->Misc->use FFms2000
  
• enabling Filtering->Avisynth->Misc->LibavVideoSource instead of FFmpegSource
  
• enabling Config->Internals->Handling->Ignore all input time codes
  
• enabling Config->Input->Decoding->CFR output
  

If none of these help I would need the source file to reproduce the problem
