[HELP] 23.976 (variable) to 23.976 (constant)

[Miranda]

Is there a way to do this without creating duplicate frames? It's an mp4 file, badly ripped from a 29.97 VHS tape of originally shot on film footage.

Media Info reports:

Frame rate mode : Variable
Frame rate : 23.976 (24000/1001) FPS
Minimum frame rate : 23.974 FPS
Maximum frame rate : 23.981 FPS

Thanks,

If the mp4 is simply wrong flagged:

• enabled "Config->Internals->Handling->Ignore all timecodes", and
  
• enable "Filtering->Misc->Owerwrite Input->Overwrite input frame rate" to 23.976
  

Side note: since the difference between min&max frame rate isn't high, you propably are fine with just using this.

If the source is indeed vfr with:

Minimum frame rate : 23.974 FPS
Maximum frame rate : 23.981 FPS

(and the min frame rate could be lower in reality, keep in mind, MediaInfo only looks at the first 100 or so time codes.)

you could:

• enable "Config->Input->Decoding->CRF output"
  
• enable "Filtering->Misc->Overwrite Input->Overwrite input frame rate" to 23.976
  
• enable "Filtering->Vapoursynth->Frame->Misc->FillDuplicateFrames" (SVP or RIFE are recommended)
  

This would tell Hybrid to tell the SourceFilter to decode the source to 23.976.
Since the sources 'Minimum frame rate' is below your target frame rate you fill get duplicate frames.
So to remove these you tell Hybrid to replace duplicate frames with interpolations.
