Converting VFR to CFR with HandBrake

This is a test to understand what happens when a user responds to an old thread. This thread was started in 2017 and it's last post (before my new one) was December 2018. I am replying to the original post, so I think this should send an email notification (for those, like me, who track this forum via email) with the original topic ("converting vfr..."). And my fear is that it will not appear in the current list of PR topics, because that sorts by original post date. Let's see....

Good thread Neil. Here's a preset I created a few weeks ago for converting VFR footage into near-lossless 30fps H.264 CFR footage (RF=5). I use this to convert screencasts captures created by Microsoft's Expression Encoder. For more general usage I recommend an RF of 20-24 instead (it's the "VideoQualitySlider" value in the preset).

To use this preset, copy the contents and save it to a file with a .json extension, then import in Handbrake via Presets -> Import from file.
