Raymond LutzFor now enjoy this dual-system sound demo. Stay tuned for a multicam demo with Olive and OpenTimelinIO
Here is the camera recording: image + sync signal (fingers sound is absent, remember: this is a dual system sound set-up):
This is the ZOOM H4n Pro recorder tracks. Note the thin spikes in the right channel (the yellow ovals): they are the sync pulses from the GPS, straight on the UTC second (the left channel are the fingers snipping). Those sync spikes are present in the movie too (by construction)
Postprocessing with dualsoundsync.py, aligning the spikes in the audio recorder file with those in the camera file:
$ dualsoundsync /media/shooting_files_rep scanning rushes_folder splitting audio from video... splitting audio R and L channels trying to decode YaLTC in audio files 1 of 4: nope 2 of 4: ZOOM_Rchan.wav started at 2021-10-13 01:45:08.263145+00:00 3 of 4: nope 4 of 4: fuji_a_Lchan.wav started at 2021-10-13 01:45:14.361967+00:00 looking for time overlaps forming pairs... joining back synced audio to video: dualsoundsync/synced/fuji.mp4
Tadaam, fuji.mp4 automagically synced!
