Steamboat Willie Restored Audio Test (Flutter removal)
I tried to fix the flutter with the demo of Celemony Capstan.
It's not perfect as it's the first time I tried the software, also there was the issue of syncing the video later that I had to do manually. There should be some settings for video, but I didn't try them.
Anyways it's just a test that shows what is possible with this kind of software (Izotope RX Advanced Wow and Flutter can also do this). But it definitively will take some time and work, and the software is very expensive.
