I'm working on my first video, and it was harder than I thought to sync the video with the MIDI. My process was to render the audio from Reaper and sync that to the video footage first, import that to SeeMusic with the exported MIDI file, and try to sync them. I'm open to any suggestions on how to do this better. It seems like it works better when I add some blank space at the beginning of the video, giving the MIDI notes time to trail down the screen.
There is a feature that would definitely make this easier, which would be to make it possible to see the audio waveform from the video (or imported audio). If there was some way to slide the video around to sync the first note with the first MIDI note, that would be amazing. Or if sliding the video was too hard, maybe being able to place a marker on the waveform for the first note and then have that sync to the first MIDI note. Thanks!
