Description of problem or question:
I am wanting to edit video captured from US over-the-air broadcast (mpeg2 1080i telecined 29.97fps) to remove the commercials and interlacing. My first step is to use Handbrake to detelecine into a 23.98fps progressive video which I can then edit in Kdenlive to remove the commercials. The problem I'm running into is that Handbrake is outputting variable frame rate even though I've selected "Constant Framerate" on the "video" tab.
Steps to reproduce the problem (If Applicable):
Feed Handbrake a video file, select "Constant Framerate", get variable instead.
HandBrake version (e.g., 1.0.0):
1.6.1 (x86_64 linux & macOS/Arm64)
Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):
Tried it both on linux (Manjaro stable with kernel 6.2.7) and macOS (Ventura 13.2.1) with the same results (MediaInfo reported both as having variable frame rate and Kdenlive agreed.) Below is the log from the macOS run.
