timecodeSecondsToFrames method
returns timecode frame count from timecode seconds. Timecode seconds are always based on the integerFps and that's why drop frames are needed will roll over after 24 hours
Implementation
int timecodeSecondsToFrames(double seconds, {ignoreDropFrame = false}) {
seconds = rollover(seconds);
return seconds.round() * integerFps;
// return (seconds * ((isDropFrame && !ignoreDropFrame) ? integerFps : fps)).floor();
}
