The advanced stuff behind how the VClean Player works
« on: November 18, 2014, 06:32:18 PM »
We worked extremely hard on creating a way to effortlessly have the clean files line up with most movies it will encounter without having to consult a large list of custom offsets for each and every version of a movie out there. A good example of this method would be subtitle files, where you are required to have a thousand unique subtitle file for every single version available.

Advanced Logic and Math

To counter this method the VLClean Player uses extremely advanced logic and math to try and ensure all the filters are compatible with each other regardless of where you obtained your video backup. Before a clean file creator uploads their filters, they are required to record their "Original_offset" in the clean file.

This is where the "Offset" button on the interface becomes vital. When used, the Offset button takes your input video file and uses advanced programming logic to calculate the length in milliseconds to the first audio spike of a predetermined decibel level in your video file, when you place your video file in VLClean and hit the "Offset" button, VLClean then records your video file's predetermined decibel level, uses more advanced math to compare to the Original_offset then displays a collection of 1-3 offset numbers that should make your filter line up perfectly.

What if the offset numbers are wrong?

Sometimes, on rare occasion the offset function is unable to calculate an actual working offset number. The causes are a number of things including extended/theatrical run time differences, encoding errors, run-time compression algorithms. To manually fix most issues check out our guide on custom clean file offsets. Make note though, that on rare occasions the video backup's may have runtime compression where the video actually plays faster then 1:1, like if were watching a movie on fast forward but instead of a speed of 2x its more like 1.2x, this will cause the filter to be off no matter what and you should consider re-creating/obtaining your backup.

It should play fine in RMP.

When you play the file in Plex, press the down arrow, does it stay Video: Copy or Video: Convert?
