Description
Converts a variable frame rate (VFR) video to a constant frame rate (CFR) video with the help of Matroska Version 2 Timecodes.
Requirements
- TimecodeFPS (clip, string "times", int "numfps", int "denfps", bool "dropped")
- clip = last
- The clip to convert from VFR to CFR.
- clip = last
- string times = "times.txt"
- The path to Matroska timecodes (v2).
- string times = "times.txt"
- int numfps = 30000
- The numerator of the CFR.
- int numfps = 30000
- int denfps = 0
- The denominator of the CFR
- int denfps = 0
- 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.
- bool dropped = false
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"))
