so when you sync to a fingersnap on video at the same time as a snare, do you line up the initial frame of the snare or the first loud frame? and then do you line up with the blurry frame of the snap being performed, or the first clear frame of the snap being completed?
the first loud sounding frame and the first clear frame of the closed snap should be fine, then watch it and see if it feels right. but actually in most cases, if i am snapping to a snare drum, it probably means i was listening to a playback of the song while recording. so what i do when the video is imported is i synchronize the room audio to the track and then everything is automatically at the right time
