Description

Converts a variable frame rate (VFR) video to a constant frame rate (CFR) video with the help of Matroska Version 2 Timecodes.

Requirements


Syntax and Parameters

TimecodeFPS (clip, string "times", int "numfps", int "denfps", bool "dropped")


clip   = last
The clip to convert from VFR to CFR.


string  times = "times.txt"
The path to Matroska timecodes (v2).


int  numfps = 30000
The numerator of the CFR.


int  denfps = 0
The denominator of the CFR


bool  dropped = false
If true, it will throws an error if there are frames dropped in the conversion. Good to figure out if the CFR is set too low.


Examples

Convert a VFR video clip to CFR FILM (23.976fps):

FFVideoSource("myclip.mp4", timecodes="timecodes.txt")
VFRtoCFR(times="timecodes.txt", numfps=24000, denfps=1001)

AudioDub(FFAudioSource("myclip.mp4"))
