One benefit of not using fpsnum, fpsden is you get unique frames - this is beneficial if you were using temporal filtering, or if you were using "slow" filters such as some machine learning - there is no reason to use duplicates You can add ChangeFPS to add the duplicates frames and make it CFR afterwards . There are also VFR to CFR avs plugins that read the timestamp/timecodes file if you needed CFR |

The video is decoded at the average frame rate, but if you happen to be encoding with the x264 encoder, you can add the timecodes to the command line and it'll encode in VFR mode. --tcfile-in "D:\timecodes.txt" It's been a while since I've encoded anything as VFR, but the first line of the timecodes file should look like this: # timecode format v2 or this: # timestamp format v2 I can't remember if x264 accepts both these days, but if the timecodes file isn't recognized, try changing the first line. |

At the risk of being argumentative, ChangeFPS can't convert VFR to CFR correctly. If you had an imaginary video where the first half was 15fps and the second half was 30fps, the average frame rate would be 25fps. If you used ChangeFPS(30) to convert it to 30fps, the extra frames would be inserted evenly throughout the video, but to keep the A/V sync, the extra frames all need to be inserted in the first half.

I also mentioned avs plugins that read the timecodes when converting to CFR, which is better way to do it when you have audio. https://github.com/Asd-g/TimecodeFPS https://github.com/jojje/VfrToCfr-the-other-one |
