The goal of this page is to compare subframe rounding and handling of fractional framerates of various DAWs and NLE. – feel free to add values for any DAW and NLE that is yet missing:
Dial to the given audio-frame number, then change fps setting in the DAW and note down the HH:MM:SS.FF
timecode that corresponds to the given audio-frame.
Audio-frame: 964965602 @ 48KHz

uses fractions for fractional framerates ie 30000/1001 = 29.970029…
uses limited fixed float for fractional framerates ie. 29.97, 23.976. bug: uses 24.976 instead of 24.975
