After you’ve added a recording, we’ll open the syncpoint editor by default.
If you’ve inadvertently closed it, or you close your slice and come back to it later, you can open the syncpoint editor by clicking this button at the top right of the editor:
With the syncpoint editor open, you’ll notice a waveform of the recording. This is to help guide your listening as you mark the measures of the music.
If you’ve just uploaded a recording, the waveform may take a few minutes to process before it appears. (Long videos take more time to process.)
In addition, we currently don’t generate waveforms for recordings of type video URL.
But in either case, have no fear — the syncpoint editor is still fully functional even if the waveform is missing.
